Saitō

Saitō (斉藤) exists in Seraph of the End where he previously used the alias Makoto Kijima (木島真) while working for the Brotherhood of a Thousand Nights (Later referred to as the Hyakuya Sect). Addressed by Urd Geales as Rígr Stafford (リーグ・スタフォード), and additionally referred to as Rigr by Shikama Dōji, it may be this is his true name.

In the ancient past Saito lived as a vampire, a second progenitor along with Urd. Leaving the progenitor council, it transpires that Saito founded the Hyakuya Sect in response to the nascent human organization created by the First. Acting as an experimental subject himself to conceal his vampire traits, Saito would come to have his body made up of chains. Hiding himself in plain sight, Saito took an interest in Guren Ichinose during the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen prequel light novels, and its manga adaption, where he was aware of the incoming apocalypse.

Appearing in Seraph of the End: Vampire Reign, he found Krul Tepes before coming across a vampire he sired, Ferid Bathory after some time apart. Active once more, Saito's resurgent Hyakuya Sect had developed its own army, one strong enough to launch an attack on Shibuya under the control of the Japanese Imperial Demon Army. His true target the First, he had the capabilities to attempt a capture. Calm and in control of a situation, Saito would progress further in his goal of learning more of the First's activities.

Appearance
He appears as a nondescript man with a business or gentleman-like bearing. Saito has short clean-cut black hair with bangs, where there is a parting on his centre right and again near the middle. This leaves his bangs uneven, with a conspicuous section of hair across his forehead. While the front section of his hair is the only part that can change depending on how it is swept, it is often to his left. Saito's hair is short enough to keep his ears visible, which are not pointed like other vampires due to bodily modifications. Although he actually has red eyes, Saito wears colored contacts over them to hide his vampirism, so they are a dull black. Vampire traits such as his fangs are also hidden.

Like other Thousand Night members, Saito wears a business suit that includes a collared white dress shirt of which the long sleeves can occasionally be seen at the end, and a relatively thin black tie. A black dress jacket is worn over this, which is fastened together by three buttons, and Saito also wears identically dark pants. Dark grey socks are also worn, in addition to laceless dark dress shoes.

Before physically altering his appearance, and dressing in a style consistent with the time period he is in, during the events of the past in Ancient Greece, Rigr's original appearance was that of a typical young-looking vampire with the physical age of someone in their late teens to early twenties. His hair was quite long and reached down to the back of his neck. Even when long on the sides, Rigr's pointed vampire ears were visible, where it is probable his eyes were also red at the time. His bangs reached over his eyebrows too. While Saito's hair is now black, it was light colored, his eyebrows included.

Clothing worn in the past was in keeping with what poorer members of society would have had. Although extravagant clothing was an option, it did not seem to have been worn casually. Basic tunics were a consistent clothing choice, where one was light in coloration. Across time, the tunics shared that Rigr had the top of them fastened with a string like material in a cross pattern. While Living in Romania, Rigr wore a dark medieval like tunic then too, with bracers on his arm. Additionally, light pants were over relatively dark boots. In a rare case where a sword was possessed, Rigr kept it on the left.

Personality
Pensive, Saito often contemplates matters at length, particularly when patiently awaiting developments. Speaking aloud to himself, Saito shares how he wishes the First would stop awakening so loudly as now others will get in his way. Giving thought to matters, more than once Saito comments on how topics such as what they are, and how many years has it been since he last saw someone, to be good questions. Often, Saito already knows the answer though. It was a good question in his view, where Saito could not say how strong he was, although clearly did know. This is a similar case when in pressuring situations. In no particular hurry, Saito will consider a situation and give thought to his options. In both events Saito is not in actuality overly bothered about potential obstacles, he will stick to what he has his mind on regardless.

"It seems this was a trap meant for me after all. Now then... What to do? Should I leave, or should I allow it to play out?"

- Chapter 50: "Brothers in Blood"

Calm in enacting plans as well, Saito acts at his own pace and is rarely perturbed. This remains the case when Saito is attacked; cut apart he is content to let it be observed how it is all for naught. Appearing joyful at being sliced by Guren, he would also be undaunted at being dismembered by the First. Speaking as he would normally, even in instances such as having his head detached, Saito also does not take into account how horrified others might be at his state. His severed head continues talking with Kimizuki, even with the threat of the First nearby.

A surprised expression is reserved when accused of trapping Krul, and when sensing the First's awakening. Genuine or not, Saito does not hide such an expression where often he conceals his true feelings under a warm smile. In response to surprises, Saito focuses on his objective at hand and attempts to avoid them. With Urd arriving in Japan with a host of vampire nobles, Saito fled rather than engage with them. Where it was a trap set by Ferid, and seeing him again after time, Saito still headed to where his goal concerned him rather than enact punishment, or speak further.

Having a pleasant demeanor, Saito is exceptionally nice to both followers, and those hostile to him. Although vampires, generally speaking, regard humans as livestock at best, and allow ranks to influence their views of other vampires, Saito does not look down on either in the same manner. Where the world has been divided between human versus vampire factions, Saito employs both human and vampire forces in his Hyakuya Sect, all acting under one banner, the only major organization to do so.

For those of interest, Saito treats Mika gently and gives him money for ice cream when out walking with him in the summer of 2012. However, where Yu was acting temperamental, Saito opted to drag to the orphanage on Christmas Day. Blunt, Saito tells Yu that his home went up in flames. Further, that Yu was so hated by his own parents that they tried to kill him. Despite that, Saito mentions that in the Hyakuya Orphanage, everyone there was just as unwanted as him, therefore he would have a big, new family. In at least trying to get on someone's level, Saito resorted to different methods when interacting with others.

In forming alliances or engaging with those he can have a use for, Saito attempts discourse rather than ruling by force in such cases. While he indicated an idea that he was superior to Urd as he was still a vampire where he was not, Saito addressed how they were both brothers sharing the blood of the First, and attempted to make use of that connection to persuade him that they should stop interfering with one another's plans. It was a similar happening with Guren, where Saito spoke to him first of their shared enemy in the Hīragi Family. Also in both cases, Saito opted to fall back rather than fight, where dialogue would be successful later in having them work together.

For his position and what he is working towards, Saito is not particularly violent, especially when compared to others. Rational, when attacking it is done swiftly and effectively. Assaults may also be tests to induce changes in others. Missile strikes he orders on a number of aircraft successfully hinder other vampire progenitors' progress for a time, done not out of malice but to ensure he could act first. It is an attitude that can help him taking into account what he may be after, but does not seem like one that would make the best use of the capabilities he has. Nevertheless, it does not stop Saito from being proficient with the many strong powers at his disposal, a non-violent streak does not prevent him from using chains and spells decisively when he wants.

A rare case of a vampire embracing human based creations, Saito also employs the use of spellcraft. Not being dismissive of something based on who made it, Saito neither disregards items that are strong, though not as powerful as his abilities as a second progenitor. Still helpful to him either way, Saito uses spell tags and other magical capabilities for supportive measures. Analytical enough to consider why vampires would not use notably helpful contraptions, Saito is sure to exploit these weaknesses himself for his own advantage.

"It was an illusion. One of the kind humans can create. Vampires have a bad habit of looking down their noses at humans... ...Making it all too easy for them to fall for human tricks."

- Explaining a spell tag created version of himself that appeared to break out a prison, and fight other progenitors.

Where many keep their secrets, Saito is forthcoming in providing sensitive details that only a select few would know. In attempts to bring Guren over to his side, Saito detailed the very seismic event of how the world would end. Information Saito has is used to gain favor with others. Stating he was aware of why the First took other third progenitors but not Lest Karr, he offers these details, and made it all the more enticing by emphasizing the urgency.

"Let me out and I'll tell you. Urd will surely kill me when he comes. Then the secret you want to know so badly will be forever out of reach."

- Framing it as a last chance to persuade Lest Karr to free him.

It is not the same story when it comes to sharing details about himself. Calculating, Saito goes to great extents to hide his true strength and identity to new people. While facing Guren in First Shibuya, Saito would not reveal his real name at first which done little to benefit him given he was seen as an assassin. It is difficult to ascertain his true nature. This is not helped when he professes things that may not be the case. Suspected of being behind a plot to trap Krul, when accused of having Ferid serve as his lackey, Saito unconvincingly claims that he has no idea what she was talking about, even though it really was the case he was not involved with Ferid's plan.

On account of their very being, where vampires generally do not express emotions aside from a desire for blood, feelings shown such as amusement is considered abnormal enough to deem one eccentric. Even considering normal standards of humor, Saito not only displays a humorous streak, but one that can be alarming. This is all the more disquieting when he exhibits it during times of danger to himself.

"Oh, this? I woke up one morning and it was like this. Isn't that strange? Ha ha!"

- Answering the First on what happened to his head, when it is floating in the air while connected to his body by a chain.

It may not be intentional or may be so natural to him that he does it without anyone picking up on it, yet Saito could have a surreal sense of humor, as illustrated with mannerisms and certain behavior. Speaking as his body is being re-attached via chains, Saito also decides to hang upside down from the ceiling. Self-deprecating, Saito spoke of doubting his own capabilities of being able to capture the First and added how he felt he would fail. Feigning ignorance at decidedly not regular occurrences may as well be a personal hobby for him. Regarding the chains in his body, Saito speaks how he just woke up one morning and it was like that. Rhetorically asking whether that is not strange, Saito then laughs to himself as he enjoys quite the grand time.

His sense of humor also supplements one of Saito's most distinguishing traits, namely having the deceptive habit of saying the opposite of how he feels on the inside. Although upfront in telling the First he was restraining him, Saito then professed that he was not at all confident and had the feeling that it would fail utterly. A pretense where his words did not reflect his well-prepared actions, Saito seemed sure his aim was feasible, which it likely was given his challenge against the First.

Reverse psychology is used effectively on targets. It functions all the better when Saito, through intuition or background knowledge, has a good grasp of how others may react. A contented guise accompanied with his words can induce combatants into attacking, where Saito awaits like a claw-trap, only one far more lethal to a greater number of beings.

"Yes, I would die quite dead. Please don't cut-"

- Pretending that cutting the chain connecting his head and body would result in his death, knowing full well that the chain would be cut, to result in a huge mass of chains springing out into the First.

Maintaining a facade even with it clear his actions are a ruse, Saito continues to downplay what he has prepared. Armed with something monstrous that even Shikama Doji seems wary of, Saito is afraid to say how the beasts of the apocalypse he has at hand are all smoke and mirrors. A deeply misleading claim where they are more than capable of crashing into the First's scythes. Keeping an eye on how the battle is going, Saito remarks whether the First just became stronger, and thrilled, he orders a counter-measure at the right time. Being duplicitous is helpful to Saito, but equally as prominent is that he derives happiness from it. In all such situations, Saito had the greater retaliation for what was sent at him. Further, the conflict was going his way.

"Uh-oh! Don't tell me you just got even more powerful."

- Drily commenting on the First's strength, before activating the full curse system when the First fights how Saitō wants.

An appearance of being anxious is shown when Guren threatens to overpower and kill him, this was despite the fact he is actually far stronger. Another display may have been one of slight exasperation when the attack on the school goes off schedule. Also commenting on his odds at coming across Guren and Shinya there, it is that he intentionally sought them out.

In times of what may be genuine trouble, Saito reacts with worry. Prepared to double-cross Guren in the middle of an intense fight with the First, he saw the chance to drain power to supplement his own. Betrayed in turn, Saito's expression of shock when he was stabbed with a Sinful Key by Ferid seemed real. Secluding himself in an alleyway, in the aftermath of an assault that left his entire lower torso missing, Saito weakly considered what further parts of his plot could be enacted. Although Ferid seemed a threat upon his return with the sinful key, Saito was fast enough to attack with his chains, however he still acted to restrain rather than destroy this menace.

Not as concerned with someone who had successfully ambushed him and blown half his body off with a sinful key, where the injury was not regenerating as fast, Saito anticipated greater problems incoming. More conscious of Urd's arrival, planning ahead, Saito's thoughts in a soon to be even more dire situation involved having his body recover. Not being weighed down by pride is a great asset for him, in welcoming Urd's lifeline of an offer of help, after accepting, Saito found an expected problem dealing with the threat of Ferid on his behalf.

Fear does not impact Saito, even when perhaps it should. Having his severed body investigated by Ky Luc he matched his curiosity with an interest of his own. Unfazed at the comment that all of his bones should be broken, Saito remained undaunted despite his precarious state. Escaping, yet being caught again did not result in dread, neither was anything incapacitating felt to his emotional state when confined to a magically imbued prison that was formed to stop stronger beings such as him from escaping. Even with the presentiment that Urd would kill him, Saito was not afraid of that, rather it provided an opportunity for him to only claim to be scared.

"Oh no. I'm scared out of my mind. Please don't pick on me."

- With Ky Luc picking up that Saitō looks in total control he expresses otherwise, which greatly provokes Ky Luc.

His hunch on the mark, where Saito's meek allegations that he was not as strong as reported, and particularly the submission that he was frightened could have worked was in inducing Ky Luc to attack him, and so afford the chance of damaging his prison from the outside, for him to escape. While such a hypothetical occurrence did not come to pass on account of Lest Karr's interference, Saito still riled him with offers of news on his background. Ultimately, although Saito knew where to metaphorically stick pins, yet where his provocations did not yield results, he still seemed to delight in them anyway.

A sense of coldness, outwardly indistinguishable from sereneness is maintained when taking actions that correspond with being frustrated, or murderous. Seemingly at ease in a prison, Saito suddenly crushes the arm rest with his hand. Informed that this was disturbing other vampires, Saito claimed that he was bored before deciding that maybe he could pass the time by killing every single one of them. Adding that may be fun, Saito certainly does not miss the chance to deliver a candid response to those who think they are done should they mess up.

"Actually... ...I'll destroy you all even if you don't mess up."

- Answering Lest Karr's concerns that if they mess up here he might destroy them all.

A detached attitude is had towards others, seemingly on a whim. Without a word, Saito slaughters the scientists in the room with Mirai, all the while with a contented smile on his face. Although the action helped her, Saito opted to refer to Mirai as "it". With what his Hyakuya Sect is involved in, Saito is not above human experimentation.

His true objective is unclear, even to those such as Mahiru who he works with. Someone as close as Basteya who was counted on in a plan involving restraining the First only made reference to Rigr being behind it all. Where it is felt to be certain is that Saito is invested in the Seraph of the End project. He is the one who invites Mahiru to the Thousand Nights, which they both betray later on. Although Saito convinces Mahiru to become a vampire, he refuses to turn her himself.

One clear part of his motive seems to be his desire to be acknowledged and "seen" by his "Father" (Sika Madu). This seems to be one of his foremost goals and a principal drive behind all of his actions. Although never outright stated, this obsessive desire to be noticed by his "Father", is also one of the main reasons for him changing his name and appearance to that of a Japanese name and a more Asian appearance due to his "father's" preference for the country. Later during his destructive battle against the First, he was shown to have become excited and giddy at the prospect of his "Father" finally beginning to "notice" him.

Resentment can manifest in different ways, before completely reversing in some cases. After witnessing the experiences that befell Sika Madu from other angels, Saito's anger changed from resenting the First, to becoming irate that he had been shouldering a heavy burden all by himself and without telling anyone. In such rare cases where Saito does express anger, he can quell such feelings upon a change in perspective.

Critically considering matters, Saito gives some thought to whether memories he is accessing are true. After witnessing angel souls flying into humans, that he is potentially an angel is something Saito readily accepts however. It was peculiar for Saito to shed tears for two reasons, both on account of his temperament and that he is a vampire which generally are unable to feel as much. Saito found that he was crying after learning about Sika Madu's background when thinking whether he still memories from being an angel.

"?! I don't remember any of this, but... ...I'm crying. Is that...? ...Do I still have my angel memories somewhere...?"

- Tearful having witnessed angel related memories where he accepts he is one.

History
An earliest known recollection shows Rigr was a human in a prison cell along with Urd. Seeing Sika Madu before them, they were promised eternal life. Along with Urd, he was present when Ashera awakened after being transformed into a vampire. Pointing it out to Urd beside him, Rigr commented that now they are three. Feeling that things will be much more fun, Rigr picked up on Urd's statement of them being superior beings to humans. When Ashera began craving blood, Rigr told him that he will get used to it, as it will never truly go away. Rigr then suggested to Urd that they will have to teach Ashera how to deal with it. A thousand years ago, Rígr was a second progenitor among the vampires who always accompanied the First Progenitor, Sika Madu.

At some point, Rigr took up residence in a castle within a mountainous region of Romania. Questioned by Urd who was with him on whether he was leaving, Rigr did not answer, not even when asked if it was to chase the First. After drifting forward, the question from Urd was what he thought he could do, to which Rigr answered with a question of his own, namely what Urd thought he could do by staying. Hearing that Urd would uphold the laws of vampire society, Rigr commented that was amazing, and whether he would do that for thousands of years, without any hope of reward.

Remarking how selfless it was of Urd, he spoke how the First was gone and has abandoned vampire kind. Answering Urd not to sulk, Rigr added that it was not like he is abandoning him. With only the two of them remaining in the world, Rigr agreed it is true, out of all the old vampires it is just him and Urd. He then addresses whether Urd is going to miss him. When Urd wondered if he said yes would Rigr stay, he flatly replied no.

Aware that the penalty for breaking their laws is death, Rigr spoke how they laid down those laws themselves. They were building a vampire utopia, one that would last forever. Saying that he was sorry, Rigr felt their utopia was just an illusion.

"Yep. We laid down those laws ourselves. We were building a vampire utopia. One that'd last forever. But I'm sorry. Our utopia... ...was just an illusion."

- In the past within Romania Rigr considered his and Urd's plans and what they amounted to.

Asked who he thought he was to decide it was mere illusion, Rigr retorted who was Urd to decide it is real. Their parent has left them, and whether that was seen as a reason to leave too, Rigr affirmed that Urd was staying and he will protect everyone. Apologizing, Rigr was ready to draw the sword at his hip to block Urd's strike. Clashing with Urd who intended to make him stay, Rigr said could they maybe stop this, and that Urd cannot beat him.

Landing then jumping into the air, Rigr was able to cut off both of Urd's arms. Before him, Rigr stated that was enough. Where Urd always looked slightly pleased with himself when he would win, Rigr liked that so he held back every time in their previous fights. Saying that he was sorry, Rigr did not intend to hurt him.

Announcing that he would be off, Rigr was questioned with him gone who was left that can leave a scratch on Urd. As he considered the mountainous horizon, Rigr heard if he left then Urd will hate him forever. Deeming that fine, Rigr told Urd to go ahead, if that will give him a reason to keep going.

At an unstated time, Rígr turned Ferid Bathory into a vampire, though he ended up abandoning him when Ferid did not live up to his expectations. He was also a witness, along with Urd, on the day Sika Madu disappeared with Ashera Tepes. With the abandonment of vampire kind by the First, he also left his post as Second Progenitor of the Progenitor Council. Disappearing from the eyes of vampire kind for the following millennia, Rigr pursued his own goals.

Later, it was revealed Rigr had in fact followed the First Progenitor to Kyoto, Japan. Speaking how when he was still young, Rigr claims he found something there. Where the First has founded a human organization named the Emperor's Demons, he then founded the Brotherhood of a Thousand Nights in order to assist him in his goal to be noticed by his "Father". Seemingly, it also continued the First's experiments with the Seraphs for his own goals. Founding the Hyakuya Sect and injecting his own genes into the Ichinose family, ironically it pitted him against the First's own organization of the Japanese Imperial Demon Army, and the Hīragi Family. Activity was seemingly not undertaken where the First had selected the Hīragi's to become his host family of vessels for him to possess as a demon, and act as their secret patron. Whatever action Rigr took it did not prevent the Hīragi family from consolidating power and monopolizing the Magic Underground of Japan for a thousand years.

Having given up his seat, Rigr reappeared in Japan under the name Saitō, and operated as an assassin for the Brotherhood of a Thousand Nights. Having experiments done on his body, it was to the point that his vampire nature was barely noticeable.

"True. Has it really been that long since I quit my post as second progenitor? I did dye my hair... and changed my name, too. For the last few centuries, I've called myself Saitō. Does that have a nice Japanese ring to it?"

- Remembered by Krul.

Events of 2012
When Guren returns to his apartment after school with Sayuri Hanayori and Shigure Yukimi, he heads to the upper floors that has been converted to a training dojo by the Ichinose family. Within the elevator, Saito awaits and dressed in his suit he is assumed to be the owner. Going along with this assumption, when Guren boards the elevator, he notices something amiss by the elevator buttons, so Saito is caught out.

Seen as an assassin, Saito engages Guren in combat. Making little attempt to say he is not one targeting Guren, his arm in mangled, where he experiences many would be fatal blows. Not deterred, Saito hardly reacts to his would-be agonizing wounds. Black mist seeps out from his injuries as Saito's body is mutilated. On this, it is speculated that Saito is neither human nor vampire, but a kind of monster that resulted from some sort of human experimentation - a chimera. Introducing himself as "Makoto Kijima", Saito shares he is an assassin from the Brotherhood of a Thousand Nights. His wounds heal at an incredible pace, and then Saito details that he was there to offer Guren an alliance between the Thousand Nights and the Order of the Imperial Moon.

"You have a lot to be angry about, Guren Ichinose… Believe me when I say you don’t have enough power to defeat the Hīragi Clan on your own."

- An attempt to foster an alliance with Guren.

The offer refused, and with Guren warning that he will kill him, Saito hears a count down for him to retreat. Doing so, Saito in return gives Guren a warning - a warning that he would regret not having joined the Thousand Nights.

"If things continue on their current path, a viral outbreak will occur. Forbidden magics that no man was meant to meddle in will be unsealed, and our world will become one in which humans can no longer survive."

- Sharing dire news to Guren.



On another day, Saito is near the front of a small supermarket that he may have known Sayuri and Shigure were within, while Guren waits outside. "Mr. Saitō" is called to by a young boy named Mikaela Hyakuya. Presenting money to Mika for him to buy treats for the others back at the Hyakuya Orphanage, he is friendly and kind to him. Calling him Mikaela and giving him a 10,000-yen note, Saito waits as he runs off into the supermarket.

Recognized by Guren who casually strikes up a conversation with him, Saito is asked about his identity and real name. To this, Saito replies to Guren that he does not have a real name. Another offer for Guren to join the Thousand Nights is refused. Questioned what he plans to do with Mikaela, since Guren knows that the Brotherhood carries out human experimentation, Saitō answers that the Hyakuya Orphanage is run by the Brotherhood as a charitable endeavor. Adding that he had volunteered his own body for experimentation, Saito reveals to Guren that the Imperial Demons run by the Hīragi family have begun studying forbidden magic. In response, the Thousand Nights are trying to put a stop to them.

Once more, Saito extends the alliance offer to Guren. Requesting he join them, this time Guren questions where his clan would stand in this midst of the conflict. Saitō warns him that in ten days, war will break out between the two largest and most powerful magical syndicates in the country. Asked for an hour to decide, this is refused. In doing so, Saito hears Guren once more turning down his offer of alliance. Warned that he would regret not having the Ichinose clan on his side, Saito then finds Mikaela returning after their exchange.

When Mika comments about Guren having a nasty look in his eyes, Saitō jokingly cautions him to stay away from Guren. Stating that he does not know him and may be a pervert, Saito and Mika are compelled to immediately leave Guren afterwards.

During the qualifying exams, after Guren decides to forfeit his match with Seishirō Hīragi, with Shinya Hīragi's help, Saito evidently launches a surprise attack on the premises around that time. Among the weapons he has at his disposal, one includes a beam of red light that appears high in the sky above the schoolyard. The attack misses Mito Jūjō and Norito Goshi due to Guren pushing them out of the way just before the beam of light collided with the schoolyard.

The beam of light instantly massacres many of the students in the vicinity, before Hyakuya Sect assassins are sent in. Commencing the war between the Brotherhood of a Thousand Nights and the Hīragi Family, while he had alerted Guren that it would start in ten days, it has only been two days since the warning. Saito had lied, or launched his attack before schedule.

As Guren is about to draw his sword to join the fight, Saito floats down by himself from the sky to the center of the schoolyard's temporary fighting ring, now abandoned. Studying the carnage with a smile, Saito declares that everyone, the students, could all die. With Shinya and Seishirō there, Saito is asked by the former who he is.

With Seishirō infuriated, Saito is told that he made a big mistake attacking the Hīragi family. Remarking that he hates noisy brats, Saito attacks himself. Right before he strikes him fatally, Saito's assault misses since Guren manages to kick Seishirō out of harm's way and out of sight. His attacks are dealt with by Guren resorting to casting numerous spells.

Upon Shinya and Guren deciding to work together, Saito fights against both. Managed to be pinned in place, Saito's offer of an alliance to Guren is learned of by Shinya and how they met previously. As soon as this is mentioned, Saitō once more offers the alliance, this time including it to Shinya. However, when Guren refuses and tells Shinya he could decide whatever he wanted, but he refuses to be controlled, Saito is then attacked.

Calmly watching as Guren's blade descends to cut him through, Saito speaks that his body had been altered to resist such tactics. In a demonstration, Saito's body begins to diffuse into mist as he prepares his chains to deflect Guren's attack. Not enough, Saito finds Guren's blade has sliced through the chains and into his flesh.

Soon afterwards, Saito finds Guren slap on a fuda and it explodes with energy. Surprised to see the curse eating away at him, Saito is bewildered at the effect. After saying that his body had been altered to resist all Hīragi clan magic, Saito hears Guren is not a Hīragi. Fear crosses Saitō's face as Guren tells him that the curse would consume him until the point where he would be trapped for all eternity inside his sword. Calling for Guren to stop, Saito has answers and information demanded. An attempt to retaliate is done by activating a spell from his eye, but this is prevented with Shinya using a fuda.

Eventually, Saito relents and explains that one of the students had betrayed the Hīragis. Where the student had been selling secret magics to the Thousand Nights, he explains that the research project was an experiment they have been carrying out together with the student. Divulging to them that the Hīragi family was betrayed by someone important, Saito hints it is someone who despises the Hīragis family, and is higher than Shinya.

"It’s a long story. One of the students here betrayed the Hīragis. This student has been selling secret magics to the Thousand Nights, behind the clan’s back… The research project was an experiment we’ve been carrying out together with the student."

- Catastrophe Book 1 Chapter 7, page 145

Although Saito does not speak the name, he appears set on having Shinya immediately realize who it is. When Guren demands from Saitō who it is, he merely responds that if Guren wished to kill him, he might as well get it over with already. Informing him that his mission was almost complete, Saito reveals that they were here to recover research materials. Additionally, Saito is also here to pick up their "collaborator," and that his job was to simply keep both Guren and Shinya busy. His words result in Shinya running off in a panic as he realizes the trap.

Soon afterwards, Saito finds that Guren has figured out who the traitor was, Mahiru Hīragi. Commenting that he had thought Guren would be more upset since she was his girlfriend, Saito then hears him deny this. Continuing to goad and chide at Guren about Mahiru, he states that the reason she had come so far in doing all of this was to return to his side. Tempting Guren with Mahiru, stating that with the two of them together, it would make a welcome addition to the Brotherhood in Saito's opinion.

Questioned if this was also part of his mission, to wait for this moment before extending an invitation once more to join them, Saito finds their engagement interrupted soon afterwards when the Imperial Demon Army arrives. A set-up by Mahiru was to have her abducted by the Thousand Nights so that no one would discover that she was the traitor, of which Saito was likely there to facilitate.

Saying that they were out of time, Saito finds Guren refuses to let him leave, where he is threatened to be killed if he does not give him any information. Alerting Guren that if he kills him, he would never see Mahiru again, Saito hears that Guren is fine with the idea. A matter for him to consider is Guren saying that he did not grow stronger with the intention to see Mahiru again.

At this, Mahiru herself appears and Saito sees her engage with Guren with her newfound powers due to the research of cursed gears. After awhile when Mahiru starts to slowly be consumed by the demon curse, Saitō intervenes by wrapping one of his chains around her darkening arm, suppressing the power. Informing her that they are running out of time and that they must leave, Saito finds she agrees with him. Although questioned by Guren on what he did to Mahiru, when attacked, he is defended.

When Guren refuses to come with them again, Mahiru then tells Guren there was something important she wanted to tell him. In response to this, Saitō seems to panic and advises her to wait, but he is ignored before Guren is warned of the apocalypse and end of the world that would soon come around Christmas. Afterwards, Mahiru disappears through one of the smokescreens and Saito is left alone with Guren once more.

By this time, Saito acts tired and exasperated before stating that they have gone far off schedule. If Guren wishes to get in touch with the Thousand Nights in the future, Saito says he should go to the Hyakuya Orphanage and speak to the director there. After this, Saito promptly leaves.

Some time later, the 6 p.m. news shows the fire at an apartment complex. A disheveled woman steps out of the crowd and screams for Yūichirō. She screams about a demon and says the fire should never be put out, then adds the demon child should be killed immediately. After she dowses herself in lighter fluid, but prevented by setting herself alight by firefighters, Saitō appears and approaches the camera before the footage is cut.

When attacking First Shibuya High School with the rest of the Hyakuya Sect, Saitō orders his soldiers to rape Sayuri and Shigure in order to make Guren become a demon more quickly. When the pair realize this, they attempt to swallow poison, but Saito uses his chains to pull the poison capsules from their mouths. When Saitō notices Guren’s arrival, he steps back, while Guren slaughters the Thousand Nights soldiers.

Applauding him, Saito encourages Guren to give in to the demon’s curse. Seemingly cut in half, it is revealed as an illusion. Informing him that Norito is holed up in the fifth-floor girls’ bathroom, while Mito is in the audiovisual room, Saito says Guren will not be able to resist becoming a demon once he saves them. With Mahiru joining Saitō, after heading to the roof to torment Guren and his aides more, they then disappear.

Within Guren's apartment, Saitō awaits lounging on his sofa. At this time Saitō reveals he is actually a second progenitor who has been alive for over 1000 years. Saitō ask Guren to kill his servants and join him.

On December 24th, Saitō is driving Yu to the orphanage. Telling Yu that the children at the orphanage are kind and they will get along, Saito hears the boy say he cannot get along because his parents said he was a demon child. To this, Saitō decides not to tell him that they were not his real parents. Instead, Saito tells Yu that children are cuter when they are smiling.

Opting to tell Yu that if he wants to die, Saito specifies he could open the door and jump out of the car. After Yu says that as long as there are good things left he will not die, Saitō thinks about how he does not even remember if he had family or friends or good memories. Calling the director of the orphanage, Saito speaks how he is bringing a child of great destiny and a demon. Not elaborating when the director does not understand, Saitō considers about how it is raining, which will be beautiful with the blood being shed.

On December 25th, Saitō notes that it is snowing in Tokyo, and regards his former comrades the vampires who raided the Thousand Nights. He thinks about how everyone is acting crazy before the world is about to end. Bringing Yu to outside the orphanage, Saito tells him that the children could be his family. When Yu says he does not need one, Saitō remembers that he once had family members that were important to him, which would mean he would lose them.

While wondering how many hours are left, Saito's phone continuously vibrates. Knowing that they are reports about what is going to happen at the end of the world, he does not look at them. Looking up at the sky, Saito contemplates how he cannot save the world so he must plan for the future. Smiling at Yu, he brings him into the Hyakuya Orphanage.

Events of 2013
Saitō sends a fifth progenitor vampire, Caek Sanorium to contact Guren that his master has taken a 'liking' to Guren. When Guren collides with the wall of a building, his spine is broken along with his internal organs. As his demon curse activates and begins healing his injuries, while he could not stand, Saitō visits the injured Guren and mentions that the world has ended after all. Questioned if there is a point wearing contacts despite him being a vampire, Saito answers that it makes him look more human. Stated by Guren that he is not human either way, Saitō replies nor he is a vampire anymore.

Asked what he is then, Saitō finds his question interesting. Wondering if anyone knows what they are, Saito requests an answer from Guren. Speaking that all vampires were human once, Saito adds it is just as Mahiru was. When Guren feels that he is the one responsible for turning her into a vampire, Saito answers though she is not one anymore. Demanded to know what he did to her Saitō simply replies: what she wanted. After Guren responds that she swallowed the demon and went inside him, Saitō reveals he already knew.

Finding Guren's sword levelled at his throat, Saito is asked again what did he to her. Repeating his answer, Saito is questioned what is it exactly that Mahiru wanted. Answering it was for him to 'survive', that she wanted Guren to become his strength, supporting him from within. Questioned if he has her to do that, Saitō admits so but also adds he would not take all the credit.

Pushing Guren's blade out of the way, Saito asks Guren directly what he thinks of this world. Going on to discuss who built this world, Saito also raises the one who made it the way it is. Where Guren responds how should he know, it is suggested that Saito read philosophy. Taking this as nonsense, Saito is of the view that it is written by people whose life-spans are measured only by the tiniest fraction of his own. Reminded that Guren is only sixteen, Saitō laughs as it is a good point considering someone who is that age has been through a lot.

With Guren regarding the world that he himself destroyed, Saitō continues and says that he went through something similar as well. Mentioning when he was about Guren's age that 'it' happened to him, Saito explains the details how he was nearly seventeen or in his twenties when he was sired, yet finds his memory has grown hazy. Questioned what exactly is he talking about, Saitō mentions the only man in this world who has been alive longer than him. Naming him as the one who sired him, it is the first progenitor.

Having no idea what he is talking about, and so his point is asked, Saito holds up a finger and shares his belief that the story of this world has been written by the First. Although Guren does not understand, Saitō continues anyway to ask about the First, and wonder what is his final objective. On whether he is a god, Saitō comprehends so, yet says he is a vampire in a case. Continuing, Saito reveals he is been pursuing the First. As for what reason, Saitō tells Guren it is for him to know. Even if he would tell him, Saito feels Guren would not understand as he has not lived long enough to comprehend it.

While Guren states this has nothing to do with him, Saitō interjects that he is not a scion of the First's tale but Saitō's 'child'. After Guren says he has only one father, the deceased Sakae Ichinose and no one else, Saitō tells him that is beside his point. Regarding what is the point, Saitō starts by speaking that there are two separate occasions on which he has played a significant role in shaping the history of magical society in Japan. Sure that Guren already knows one of them; Saitō was the one who created the Brotherhood of a Thousand Nights, and explains he did so to oppose the Order of the Imperial Demons.

When Guren says he did so due to the Imperial Demons being manipulated by the First, Saitō is impressed by how perceptive he is. Smiling, it is added that when it comes to it, nearly everything in this world is his creation. Some things did not go according to plan as although he created the Brotherhood of the Thousand Nights, none of them seemed to do what he wanted them to as they began conducting their own research without Saitō's knowledge. In fact, all of them seemed to play right into the First's hand.

As all of it is his creation, and in fact all part of his plans all along, Saito asks himself what should he do. The more he tries to catch up with him, the further ahead he seems to get. Feeling he is being trapped, Saitō feels he then had no choice but to take a different track; he would do nothing but instead change what he was doing. He planted his own seeds in the fields the First had cultivated. When Guren asks him of the changes, Saitō raises two fingers. Explaining his second major act within the magic-using worlds, 100 years ago he arranged for the second most powerful and influential clan in the Order of the Imperial Demons after the Hīragis, the Ichinose clan to come into conflict with their masters.

Explaining that he used a woman to do it, she was an alluring girl and with a little extra help from his own sorcery, she drove a wedge between the clans in no time at all. As the Ichinoses would become outcasts, as if the clan itself is in the balance on the verge of dissolution, Saitō intervened. Telling Guren that his story is not like in the movies as there is no happy ending, he starts saying the girl in his story was conceived with a child. Into that child, Saitō inserted a small amount of tissue from his own body then clarifies that Guren is the descendent of that child.

Finding Guren swinging his sword, using all of his strength, with the intention to kill, Saitō effortlessly intercepts the blade with his two fingers. When Guren calls all the power from his demon, and shouts an intent to kill, Saitō praises how strong he become. Speaking how he is making his 'dad' proud, Saito's words anger Guren more. Since Guren refuses to believe that he is his father, Saitō agrees, then specifies he is more like a greatest grandfather, which makes them both strangers.

Failing to quell his fury, Saito tilts his head to the side, to avoid the sword Guren swings at him. While Guren is undeterred, and cursing him to die, Saitō keeps laughing. Then raising a hand lightly into the air, in bringing it down sharply, the strike across Guren's face nearly takes his head off. Further slamming his body to the ground, the impact leaves Guren's neck broken. Where he could not breathe, and his mind was unable to form a logical thought, Saitō disregards that and is only impressed how powerful Guren has become as no human could survive such a blow.

Stating to Guren that the First is apathetic, Saito lists that he has no human heart, does not care about lives, and love or hate mean nothing to him. Supposing it is because the First thinks that he is perfect in every way, or it is just that he has lived too long, Saito considers the distance to the human race. He mentions that this is no different from the Ichinose clan, which was cast out for the sake of love. Speaking that the First is the one responsible for being outcast, it was because he did not care which caused the rise of the Brotherhood of the Thousand Nights.

While wondering again if he is dancing in the First's palm, the bones in Guren's neck have healed and Saitō is asked what could he possibly want from him. Saitō answers in him being his scion, he made him resist the First. Returning to his story, Saito mentions abducting the maiden from the pages of his story. With Guren knowing he meant Mahiru, before saying anything more Saitō cuts him off. Having nothing for their feelings, he just brought the two together and Guren fell in love with Mahiru.

Smiling, Saito he takes a dagger-like utensil out from his chest pocket. Although Mahiru-no-Yo has materialized next to Saitō, he cannot see them. Sensing their presence however, Saito asks if she is there, but does not hear her confirmation. Hearing Guren specify that her location is next to him, Saitō expected as much. While he is questioned by Guren about the dagger he is holding, Saito does not give him a proper answer. Instead he talks to Mahiru-no-Yo on whether she knows. Then swinging the sinful key above his head before throwing it, Saito hurls it to pierce Mahiru-no-Yo's throat.

Causing Mahiru-no-Yo to collapse on the ground, where Guren is angered and questioning what has he done, Saitō seems unconcerned. Stating 'nothing much', Saito mentions he just hid something called a sin. When Guren demands to know whose sin, Saitō answers him he will find out soon enough. Now, they will need to collect those sins to make their wishes that are to be granted. As Saitō is about to depart, he does not want the First to notice him. While Guren wants an explanation, Saito interrupts and says he himself will reach him even without an explanation, as he is his child and he made him to serve him.

Having disappeared when Shinya suddenly arrives at their location after his fight with Caek, a letter has been left. When Guren later opens the letter, a document inside the envelope contained information on two subjects. Their location, when they could be rescued, along with the best way to do so was also featured. Saito had left two names on the list, Yūichirō Amane and Mikaela Shindō.

Post-Shinjuku Arc
Saitō first appears in a flashback, he was taking Yu to the Hyakuya Orphanage. Mentioning that Yu's parents hated him so much, it is recalled Saito said they tried to kill him. He also spoke how Yu's previous home went up in flames.

"Needed or not, this will be your new home. It's the only place you can live. Welcome to the Hyakuya Orphanage, Yūichirō Amane."

- Bringing Yu to the orphanage.

Osaka Arc
Reappearing before Krul Tepes, who is sealed in a wall and starved for blood, Saito comments on how pathetic she has become. Although he is not recognized by Krul at first, Saito asserts she should know him quite well. He is then recognized as "the one who always tagged along behind the first progenitor." A flashback of events that occurred 1000 years ago shows Rigr was near the First.

With Krul commenting that he has changed a lot, Saito asks if it has really been that long since he quit being a second progenitor. He changed his name to Saitō, which sounds Japanese. Asked by Krul if he ordered Ferid to capture her, he denies it before remarking about the difference in power between her and Ferid. He says Ferid must have tried really hard to capture her.

Glancing at the human limbs hanging from the ceiling, Saito comments that Ferid has been an eccentric one since the day they first met. After Krul angrily demands to know if he did this, and what he is plotting, Saitō denies any connection to Ferid at all. Saito affirms he discarded Ferid a long time ago because he was unable to live up to his expectations. Speaking that this is no different than what the first progenitor did to them, Saito feels he was only interested in Ashera Tepes, who is Krul's brother, and ignored and discarded the rest of the vampires.

Asked if he is also after the first progenitor, where Krul says that all vampires despise him to some degree, Saitō judges that is a good question. Commenting that all vampires go through a rebellious phase at some point, Saito enquires if Ferid has said anything about him. As if sensing something happening outside, Saitō accurately shares how a fleet of ships from Russia has arrived. Furthermore, the ships contain Urd Geales, and a few nobilities. From her expression, Saito concludes it is not Krul who brought them, so wonders if it is his son who has summoned the other progenitors.

"Still... What brings them all the way to Japan so suddenly? They are quite in the way of things. I have already invested over 1,000 years into this plan. I'd rather not have any last-minute interruptions. Who on Earth could have summoned them here? You? No, not you. Then, who? Perhaps it was my rebellious son?"

- Speaking to Krul about Urd, Lest Karr, and the arriving nobles.

Noticing a bleeding wound on Krul's neck, he observes that a strange ointment has been applied to the area to keep it from healing. Saito mentions that a high ranked progenitor gives off a unique scent that attracts lesser vampires. Although Saito licks the ointment off the wound, he states that Urd already smelled the blood. Saito then figures that this was a trap for him.

Contemplating whether or not to leave, Saito finds Urd bursting through the door who goes right for him. Stopping Urd's fist, Saito is referred to as "Rigr Stafford". When asked if he is behind what is happening in Japan, Saitō greets him with a smile, and dodges Urd's sword slashes. While Saito is remarked to have gotten slow by Urd, he remains unfazed. Allowing his arm to be cut off, multiple spiked chains burst from the severed end and travel towards Urd. Although they are slashed away, it is except for one that pierces Urd's neck and causes curse-like marks to appear.

When Urd demands to know what that was, Saitō explains that it is a curse he had been working on for centuries with human help. After Urd claims that Saitō is no longer a vampire, he replies that remaining as a vampire is the reason why the first progenitor left Urd. Pointed out that he was abandoned too, it is much to Saito's agreement. Asked what Saitō wants, he answers by asking Urd the point of continuously living century after century, following the rules of a father who abandoned them.

Continuing, Saito raises that they are brothers coming from the same blood of the first progenitor, so Urd should not be interfering with him. Pressing him to leave, when Urd refuses, Saitō then lassos a chain around Krul and pulls her out of the wall. Using his chain to launch Krul at Urd as a distraction, Saito then sprints to the open door. When Lest Karr shows up, Saitō draws close before simply slicing through the third progenitor to get through.

Once outside, Saito leaps away. Making his way through a garden, Saito comes to a halt with Ferid in his path. Although Ferid says that he has been awaiting him as it has been a thousand years since they last met, Saitō tells him that he has no time to chat as Urd would be following him. Tempted by Ferid to kill him, Saitō is wary of triggering another trap if he tries. With further temptations, Saitō lunges at him, before proceeding to pat Ferid on the head. Saito claims that he chose "an odd one" to turn into a vampire. Before departing, Saito tells Ferid that he will forgive him for this act, but will not do again next time.

When it is recalled how Mika was watching when Yu first came to the Hyakuya orphanage, Saitō is remembered. Physically appearing, Saito is standing atop the Sunshine 60 Building in Ikebukuro, Tokyo, and holding two small cross-shaped daggers. Overlooking the devastated district, Saito muses aloud about how far the person has come in the last thousands of years. Further pondering concerns whether he still goes by "Sika Madu" or is now "Shikama Dōji".

"Dun da-da daaah. Way in the distance, I see the world is about to change. My... How many thousands of years has it taken to get this far? Founding the Hyakuya Sect... pursuing the Hiragi Family... Say, First-- No. I can't tell if you are still Sika Madu, or if you're Shikama Dōji now... But whoever you are, is everything still proceeding according to your plan? Or am I catching up to you? See? I hold two of them now. Is this, too, part of the fate which you decreed for me? Or perhaps..."

- Wondering to himself as seismic and long-planned events are on the horizon. Prepared, Saito is armed with two sinful keys.

Asking aloud if his interference is disrupting that person's plan, Saito is then informed by a suited person that it is time to go. As he leaves, it makes Saitō wonder how much time is left for this world.

Shibuya Arc
Later in Ikebukuro, he, along with other vampires across the world, feel the First Progenitor's presence. Mentioning that it has been a long time, Saito feels it seems it was recent. He considers today is the day that it begins.

Remembered as a second progenitor, Saito is also considered as a member of the Hyakuya sect when Guren and Kureto Hīragi are discussing Mahiru. He is also discussed by Ferid and Crowley Eusford, where it is known by them that Saito is one of the names of Rigr Stafford. Additionally, Saito is suspected of seeking the First out.

Standing amongst the ruins of Tokyo, near the east exit of Ikebukuro station, Saitō becomes aware that the first is awake again and really wishes he would stop doing that. Noting he is always so loud about it, now everyone will notice and get in his way. Yet Saitō wonders whether the first is being loud on purpose.

Moving to the old Hyakuya Sect underground headquarters, Saitō walks before a fleet of missile bearing trucks. Informed by a suited man that a target signal as been acquired, Saitō gives the order to launch a volley of target seeking rockets towards the aircraft transporting Urd, along with Krul, also Lest Karr and Ky Luc. His involvement is suspected by Urd, as Rigr is remembered by him speaking to the First and Yu from the past.

Admiring the crescent one above, Saitō contemplates what a lovely moon, and that it would be wonderful to be able to die on a night like this. He concludes that Urd Geales will not die though, before he is told that all aircraft have been destroyed. Deeming this news good in that it has bought them perhaps half a day, Saitō intends to move his forces onward to Shibuya. Legions of the Hyakuya Sect are before him, and Saitō proclaims that today, they destroy the Japanese Imperial Demon Army.

Having arrived in Shibuya outside the city walls, with Yu having been captured by a Hyakuya agent, Saito directs his soldiers to take him to the lab in Ikebukuro. Additional orders are to then destroy the Japanese Imperial Demon Army and capture the First. Stripping the 'Sun God Aten and Michaela' from Urd and the First are further commands.

With his army having arrived at Shibuya, Saitō stands with his eyes closed. Being informed that preparations are complete, Saito hears that the attack may begin at any time. Checking if everything is in order, Saito acknowledges that they are facing some powerful opponents. This includes the First himself, and several "family" members who bear his genetic material. Nevertheless, Saito instructs them to go all out from first contact, but once the objective is acquired, they are to retreat immediately. Checking that he is understood, Saitō raises his hand to initiate the full-scale attack.

His helicopters were able to become so close without being detected by using a curse-based camouflage, and Saitō orders them to fire. As the operation occurs, Saitō stands atop a wall and is revealed to others as being the one in complete control of this invasion plan by Basteya Irclu.

Having made his way to the area where Mirai Kimizuki has been activated as a seraph, Saitō uses six long chains from his back to murder the scientists there. Stood directly behind Shihō Kimizuki and having heard that Mirai is his sister, Saito speaks how he will have to treat it with care. Not answering Kimizuki's question of who he is, Saitō is afraid he does not have time to speak with him right now. Saitō then asks rhetorically what he means to Kimizuki, before questioning whether he should go to his sister. Not turning as the First enters the room, instead Saito politely says hi to Shikama Dōji. Where the First has possessed and is in control of Shinoa Hīragi's body, Saito is aware of his presence all the same, and notes that it has been a while.

Standing opposite the First with Kimizuki and Mirai in between them, Saitō is politely asked how many years has it been. He considers it a good question, it has been at least two-thousand years. Asked if he has been well, quite, he thanks the First before explaining that the years have been entertaining for him fortunately enough, very much so. As chains extend from his back, Saitō hungrily elaborates on his contentment that this is because he has been so eagerly awaiting the First’s return, he practically counted the days. The chains have penetrated the ground around him, and Saitō arrives at his point that he could hardly wait to show the First what he is truly capable of. There is an emphasis on making the First pay attention.

"I've been so eagerly awaiting your return, you know I practically counted the days with bated breath. I could hardly wait... ...to show you what I'm truly capable of-and make you pay attention."

- Pleased that the First found him.

Joined by Basteya, and another vampire suddenly crashing into the room, Lord Saito hears that the unification spell is ready. Where they will begin at his command, Saitō states it is good, and directs it to proceed. Answering the First's enthusiastic question as to what he will do, Saito simply replies that he is restraining them. Saitō duplicitously agrees with the First's analysis that they are all so weak. Claiming in honesty he is not at all confidant, Saito adds that he has the feeling they will fail at it utterly.

This stage of his plan involves having his own Hyakuya Sect army use spell tags to make themselves targets. Stabbed with chains that appear, they are sapped off their power which flows into Saitō where he can now suspend himself off the ground. With the First having reasoned this, regarding how powerful it makes him, Saitō deems it a good question but could not say. Curse marks have appeared on his face as Saito announces that he may as well test it. Asking whether the First thinks so, but not waiting for a reply, Saitō declares here he goes to his father. In response to Shikama Dōji instead making a move towards Mirai, he immediately lashes out with a chain. Snatching and binding their wrist, he awaits the First in Shinoa's body to react.

The opportunity is used to advise Kimizuki to take the girl and run, make his way towards Shinjuku where Saitō claims that he has allies there. His chaining broken free of, Saitō is decapitated by the First, yet his head lies on the floor still alive and well, where it is attached by a chain to his body. His head on the ground, Saito continues explaining to Kimizuki that the Demon Army was founded by the First for his personal use. As long as Kimizuki stays here, he will be experimented on so Saito advises that he should run quickly.

With his head able to be raised, Saitō insists that he would never do such a thing in response to the accusation by the First that they would be his guinea pigs instead of theirs. As Saitō's head floats above him like a balloon with a chain to his torso, he is queried on what happened to him. Replying that he woke up in the morning and it was like this, Saito then asks is it not strange.

Feigning ignorance on his state is changed to a clear appraisal that he would be quite dead if the First cut the chain connecting his head and body. In the middle of politely asking that the First please not cut it, Saitō's neck chain is sliced. He manages a smirk before a profusion of chains explodes from the opening in his neck.

The chains are directed to stab into the ground near where the First is. After they sprint away from the weapons and leap through the glass exiting the building, the chains follow them, arching out onto the exterior. Shinoa with the First within is airborne and possesses six seraph-like wings. His head reattached, Saito has now conjured before him an array of thick scaled necks ending in a range of animal heads, all with lifeless white eyes. The species Saito is armed with consist of a ram, panther, goat, wolf, lion, and a draconic like creature. Not commenting on the First's remark that it looks almost like a beast of the apocalypse, Saitō only notes its impressiveness. He attempts to assure the First that it is all just smoke and mirrors though. Then changing the topic, Saito observes that their wings are as lovely as always, just like an angels.

Viewing the scythes now circling around the First in the sky, and with their suggestion that Saitō might need to be punished, he declares it is about time. Asking if he has finally managed to make the First see him, Saitō requests his chains to come and pierce them through. His animal head weaponry dive head first upwards into the whirling ring of scythes, with large explosions resulting from the impacts and Saito sustains this assault on the First, seemingly enjoying the battle. With something sensed emerging elsewhere, Saito is asked by the First whether it was his doing. Deeming it a good question, Saito asks what they think.

With chains continuing to be used, Saitō drily remarks on whether the First just got even more powerful, and speaks how this is a problem to make his concern more convincing. Whatever trump cards Saitō has, the First will not let him use them, and he finds a lone scythe directed at him. In response, Saitō happily orders the full curse system to be activated.

Maintaining the fight, Saitō sees Guren, who has demon horns, join the battle. With his arrival and the First doubting the abilities of this trump card referred to, Saitō smiles. Commenting on the lateness, Saitō mentions he nearly died. Enquiring about the key, he has a sinful key tossed to him from Guren above. Catching it, Saito explains that according to his calculations, and considering that the First still has not manifested their real body, then the three shining keys Saitō possesses should be enough to seal him away.

Considering the possibility that the First is correct on the extent of the speed, Saitō springs into the air and announces if he ate three more demons, what then. He betrays his allies Guren, with Noya and Mahiru in the middle of the fight against the First. Moving in to bite Guren, he discovers his deception is met with a double cross from the other side.

At Guren's direction, where Ferid appears through a portal created by the Jigenso cursed gear of one of his agents, Saito appears apprehensive. Having been struck with a sinful key by Ferid who details that one key is enough to break him, there is a resulting large explosion. Visualized, Shinoa is aware of Saito as controlling the Hyakuya Sect from the shadows as she considers who they can side with.

Post-Shibuya Arc
Saitō's chest upwards, aside from the left of him that has chains from the opening, is what remains of his being. Having dragged himself to within an alley, Saito thinks how it is incredible how he is not healing at all, and puts it down to getting hit by a sinful key.

"Boy, this is incredible. Not healing at all. I guess this is what happens when you get hit with a sinful key?"

- Thoughts on his dismembered state after experiencing the detonation of a sinful key.

Asking himself whether he will be able to get away, Saitō notes his plan is not complete yet, but then finds he has been tracked by Ferid and Crowley. He comments Ferid came after he announces his intent to kill Saitō. Enquiring what his plan is, Saitō would like to know what Ferid gets from killing him. Questioned on what meaning there is to their lives, Saitō sees the sinful key raised, so he directs a chain to scrape across Ferid's cheek. Further ones are blocked, and an explosion occurs in the alleyway. Spotting Ferid above, Saitō wraps chains around his arm and holds him there. Voicing that making him a vampire was a mistake, Saitō states first and foremost Ferid was always abnormal.

With Ferid speaking to Crowley, Saitō wills himself to heal, to get his power back and focus. Although feeling he could escape Ferid and the range of the sinful key's reach, the problem for Saito is someone he really does not want to deal with is almost here, and he has to move before his arrival. Damning the situation when he hears a voice offering help, Saitō answers that the offerer was the last person he wanted it from. Regarding when he was told not to turn Ferid, he replies that it is too late for that now and if Urd meant it then he should have tried harder to stop him back then. Where Ky Luc and Lest Karr are with Urd, Saitō is again asked whether he wants help. After a moment, Saito accepts and requests that Urd helps.

After Crowley has taken Ferid's dismembered upper torso into the air, Saitō replies to Urd to let him play just a little longer. All the while, Saito also thinks just a minute more and he will at least have his skin healed enough to move. As Saitō states that if Urd takes Ferid likely then he can be scary, and for Urd to be careful, his body is pierced by Ky Luc. Unbothered, before Saitō can speak on what his chains are, his mouth is covered by Lest Karr.

He reacts when Ferid appears through a portal created by Jigenso, and has appeared behind the progenitors with a sinful key. When Crowley catches and activates it, Saitō appears happy and states that they cannot react in time for the keys effects. With this, Saito then praises Ferid. After a window shattering sound is heard, Saitō has the chains raise himself. Able to sense Ashera Tepes, with Krul Tepes and Noya Hienma, he considers it unbelievable after all that has happened.

"You're kidding. I sense Ashera Tepes. Krul Tepes too. Even Noya Hienma. Unbelievable. After all that's happened, still."

- Sensing demons and vampires, and saved by Mika turning into a demon.

In spite of escaping from the alleyway, Saitō is confined within a prison with his wrists bound, where chains strap him to a throne within a cage. Tapping an armrest and humming to himself, Saitō pays no mind to the vampires around discussing him, before suddenly crushing the end of the left armrest and damning the situation. Finding that Ky Luc is speaking to him, Saitō smiles pleasantly after hearing that the legends about him are all very old. With Ky Luc mockingly wondering whether he is really that powerful, Saitō denies it and merely affirms he is weak. Why else would he be bound in humiliation like he is. Told he has an awfully cocky look in his eye, like he is in total control, Saitō disagrees. Professing to be scared out of his mind, Saitō begs Ky Luc to please not pick on him.

When Ky Luc's provocation falters due to Lest Karr's words, Saitō repeats loudly to not pick on him. Glared at by Ky Luc and returning a look of his own, Saitō asks what, does he not have the guts to pick on him. Petitioned to stop teasing their subordinates by Lest Karr and replying that he is so bored, Saitō says maybe he could pass the time by killing every single one of them, that may be fun. Since the prison's power intensifies depending on the age of the vampire, Saitō agrees it is true, he cannot move an inch. Deeming it incredible, Saitō is surprised they could make something like this. Informed the prison was probably designed to hold him, Saitō asks whether Urd made it. Wondering whether Lest Karr thinks Urd is mad at him, Saitō hears that he is the only one Urd becomes emotional over. Concluding Urd is furious then, Saitō questions if Lest Karr thinks he should apologize. Thinking it is a good question on whether Urd would forgive him, Saitō ponders how it has been a long time, so long that he only barely remembers.

It is remembered that in a mountainous region within Romania that Rigr was exiting a castle. He discussed leaving, and who Urd was to decide the vampire utopia they wanted to make was real, when Rigr thought it was an illusion. It is recalled Rigr defeated Urd in a fight. After the recollection, Saitō asks Lest Karr whether he thinks Urd will torture him today. With Lest Karr of the view that he should be executed for breaking far too many of their laws, Saitō protests that the laws are so stuffy before questioning who came up with them. Reminded that he came up with them, Saitō remembers then decides it is okay, he will add one that says it is okay to break all the others. All the laws are meaningless, and Saito adds they can run in the halls now, give blood to humans and makes all the new vampires they want.

"Oh yeah! Okay, then I'll add one that says it's okay to break all the others. All the laws are meaningless! You can run in the halls now! You can give blood to humans and make all the new vampires you want!"

- Reminded it was himself that made what he described as stuffy laws, Saitō has some amendments as he attempts to talk his way out of imprisonment.

Turning to what Urd said, Saitō is informed by Lest Karr that it was not to speak with him at all. Replying but he came to his prison anyway, Saitō mentions how Lest Karr does want to talk to him and has questions he wants to ask. When Lest Karr replies not particularly, Saitō is certain he does. Like he said, when the First took all of the best third progenitors with him, why did he not choose to take Lest Karr.

Mentioning Ashera and Byakko then Gekkouin, along with Kiseki-o also Raimei and even Noya, they were all taken. Saito may be aware that as demons they were situated around Sika Madu, who held Yu from the past near the clear casket containing Mikaela, all the while with black suns floating above them. Continuing to speak with Lest Karr on how two were left out. One was Krul Tepes, and the other, Saitō just cannot place the name, but thinks it was Lest... Lest Karr. Ordered to be quiet, Saitō speaks why did the First leave Lest Karr behind.

"When the first took all of the best third progenitors with him... ...why didn't he choose to take you? Right? Ashera. Byakko. Gekkouin. Kiseki-o. Raimei. Even Noya was taken. But two weren't. Two were left out. Krul Tepes, and one other. What was his name again? I think it was Lest... Lest Karr?"

- Apparently aware of other third progenitors, and sharing this background to induce Lest Karr to ask him to reveal the secret why he was left by the first, so Saitō could ask to be freed first.

Maybe it was because he was incompetent or was there something else Lest Karr is lacking. Commanded to be silent, Saitō mentions Urd knows why, but bets he has not told him and this is why Lest Karr came to talk to him. In response to Lest Karr's denials, Saitō wonders just why the First did not choose him, then raises that he wants to know so badly he is desperate. After Lest Karr shouts no, Saitō simply requests he let him out and he will tell him. Adding that Urd will surely kill him when he comes, Saitō entices him further with the prospect that the secret Lest Karr wants to know so badly will be forever out of reach.

When Lest Karr declines to free him, Saitō enquires as to what the different reason for approaching him was. Informed that Lest Karr just wanted to hear what he had to say in his imprisoned state where he could not escape, Saitō asks what he was expecting. Clear that Lest Karr is not going to free him, Saitō questions if he is really okay with the secret staying secret forever. Accused of not knowing the answer even if Lest Karr did have a secret, Saitō insists he does. Called a liar, Saitō states Urd knows too before being asked to stop this poor struggle. Mentioning by the way, Saitō snaps his fingers for a multitude of chains to break out of the backrest of the throne and fly into the vampires around him. While Lest Karr and Ky Luc are not attacked, Saitō's chains have torn through the roof of his cage to form a cyclone of them and the vampires they have pierced through. Stood on the top of the formation, Saitō reveals that prison never really bound him, at all. He declares that everything that Urd values he will destroy.

"That prison never really bound me. At all."

- Failing to have others free him, Saitō frees himself from a prison meant to contain specifically him.

Freed, and with it time to destroy everything precious to Urd, he focuses on Lest Karr below. When Lest Karr speaks if they mess up here they all might be destroyed, Saitō claims actually he will destroy them all even if they do not mess up. After Lest Karr readies his rope spear weapon, Saitō remarks too slow. His chains fire towards, only to miss him, and Saitō comments that Urd sure likes keeping dedicated ones. Finding that Ky Luc has reached his vantage point, Saitō remarks that he is fast, then avoids the ranged emission from his weapon. Adding that he is powerful, Saitō asks Ky Luc what progenitor is he. Clashing, Saitō thinks amazing, Ky Luc is getting even faster. Speaking that those are not the moves of a mere fifth, Saitō announces he could see Ky Luc killing a third like that, which means he must be Urd's right hand.

With Ky Luc sharing he is going to kill him a second progenitor, Saitō aims a spike at his face. Then seeing the chain has gone through Ky Luc's head after he ploughed onwards into it, Saitō in turn has been struck in the chest. Also observing Lest Karr appearing, crackling with electricity around him, Saitō sees so this is how it is going. Judging Lest's Karr's generation a powerful attack, but it takes time to charge, Saitō feels he best dodge. Ordering Ky Luc to move, with him meaning to keep him there, and with Lest Karr's Burst Heaven's Fan power invoked, Saitō deems that is scary, it could even damage him.

Lying on the ground with Ky Luc armless near him, Saitō is missing his left leg and can only make sounds in his vanquished state. When Urd returns, Saitō is told to stop messing with his subordinates. The defeated Saitō claps his hands, and Saitō himself is sitting on his chair in the unbroken cage he was in. Displaying two spell tags, Saitō reveals it was an illusion. Explaining it was one of the kinds humans can create, Saitō adds that vampires have a bad habit of looking down their noses at humans. This makes it all too easy for them to fall for human tricks. In response to Ky Luc's bafflement, Saitō raises if he wants to practice too. He could introduce him to a Hyakuya Sect basics of spell craft class. Addressing Urd and how he built this prison just for him, Saitō decided he would not leave, just for him. Able to do so if he wanted, Saitō details he just had to make them open it for him.

"Hi, Urd. I hear you built this prison just for me. So I decided I wouldn't leave, just for you. I could've if I wanted, though. I just had to make them open it for me."

- Having remained in Urd's prison.

In response to Urd seeing he is just as insufferable as always, Saitō sees he still puts on that pleasant facade. Watching him speak with Ky Luc, he thinks how Urd has truly been blessed with good companions. Questioning why stick him in here, Saitō wonders if Urd is going to slice him to bits. Answering Urd already knows what he is doing, Saitō states he is getting revenge for the First betraying them. Told in doing so he betrayed Urd, and affirming it is true, Saitō adds to go ahead and slice him to bits then, he does not mind being killed by him. That he came here to talk is raised, and Saitō articulates that he thought about Urd every day, even when it was not necessary. With this conversation cut off, Saitō is queried by Urd how far his revenge plan advanced and is it going smoothly. From this, Saito then fixes him with a gaze.

Questioned if he invested this much time into his revenge only for it to fail, Saitō replies his revenge is still going precisely according to plan. Offering his hand, Saitō feels together they can kill the First and asks Urd to join him, he cannot do it on his own.

"My revenge... ...is still going precisely according to plan. Together we can kill the first. Join me, Urd. I can't do it on my own."

- His plan on track, Saitō asks for help to kill Shikama Doji.

Speaking how they will both get revenge on the First for abandoning them, Saitō shares that he has finally finished his preparations, that is why he came back. Adding he is sorry it took so long, when Urd asks how he plans to do that, Saitō addresses did he get some hostages already, in reference to Kureto and Shinya who Urd brought with him. Wondering what of Raimei and Byakko, rising from his throne (which he is not bound by) Saitō judges it excellent. According to his plan, the First will wake again in five seconds. It is time for them to move to the next stage too. Counting down each number, Saitō brings his hands together and states now.

Outside the prison, Saito has formed a large pentagram made up of chains from his hand that is held above him. Asked by Urd what he is starting, Saito replies he would say the climax of their little story. Turning to the cage, Saito questions why Urd created that cell. A jail that drains more power the older the vampire it holds, Saito wonders who Urd really thinks belongs in there. Chains are used to stab into Kureto and Shinya which results in the capture of their respective demons, Raimeiki and Byakomaru. The chain formation has emerged out of Kiseki-o's coffins to assail Sika Madu in his demon related location. In sending chains into humans to bind their demons, and in turn attempt an ambush on the First elsewhere, Saito is impaled through the chest by the return fire of a scythe.

Madly laughing as blood sprays out his mouth, Saito addresses Sika Madu's words that he can die now. Speaking how the First finally deigned to notice him, Saito feels Sika Madu must really be in trouble if he did that. Calling for Urd to support him, once the scythe is pulled out, Saito announces today is the day they surpass the First. Directing a chain into Shinya, it can emerge from Kimizuki's chest physically a great distance away. Able to communicate through the chain out of Kimizuki, he speaks for Guren. Stating that it has begun, Saito voices that it is time for them to put their plan into motion and to help him. Guiding him to use the drugs he gave him, Saito explains they can take their demons back from the First. Relaying the urgent communication, Saito adds they can then use Kimizuki's power to let them reach Yu and Mika to save them from the First.

"Guren? Guren! It's begun. It's time for us to put our plan into motion. Help me. Use the drug I gave you. Take your demons back from the first. Then use Kimizuki's power. That will let you reach Yu and Mikaela and save them from the First's assault."

- Contacting Guren by a chain that emerges through Kimizuki, and seeking their help in his attempt to trap the First, where Yu and Mika can also be saved from him.

When Sika Madu calls for his and Urd's assistance having come under attack from seraphs, chains pull the First into a coffin. Pulling him into the physical world, Saito stands ready waiting for the First to awaken. After a comment that the First looks like a wreck, and whether he can see them, Saito speaks how if only Sika Madu had asked in the first place, they would have gladly helped him, then addresses Urd for him to agree.

"If you'd only asked in the first place... ...We gladly would've helped you. Right, Urd?"

- With Sika Madu caught, beside Urd he speaks to the First.

Viewing Sika Madu chained in the prison that kept him, the line of conversation that is desired to be heard is the beginning of the world, to the reason Sika Madu abandoned them. Wanting to have at it, Saito adds they are all listening. Asked whether his plan went as expected, Saito questions in turn how was it, and whether the First's plan has been destroyed. Questioned if Sika Madu was his only objective or was there more to it, Saito wonders what does he mean by that before considering the question of how many sinful keys does he hold.

Akihabara Arc
Directly asking what the First is plotting, Saito also raises what ultimate goal does he strive for. Said to know that already, otherwise he could not interfere as thoroughly as he had, Saito mentions Shikama Doji wants to bring Mikaela back to life since he was his son. Commenting that he was a guinea pig to him at first, Saito wonders if it is the case that he was to be a potential body to house Mikaela in. Feeling Urd was one too, Saito guesses the First was trying to create a doll strong enough that it could hold his dead son's soul. Assuming he was a failure, Urd as well, Saito formulates that Shikama Doji moved on to the next generation, but Lest Karr, and Krul, they were all failures.

"I was a guinea pig to you at first, wasn't I? A potential body to house Mikaela. So was Urd. You were trying to create a doll strong enough... ...That it could hold your dead son's soul. But I was a failure. Urd was a failure. You moved on to the next generation. But Lest Karr, Krul... They were all failures."

- Inferring that vampires were tests by Shikama Doji to resurrect Mikaela.

At that point, Saito postulates the First changed his tactics. Recollecting how in the past he was a human with Urd in prison and promised eternal life by Sika Madu, he felt they were then discarded without a second thought. Questioned whether he held a grudge ever since the First left, Saito considers it a good question. Having been given eternal life as promised, Saito details how they needed some reason to keep living it. The days become so boring otherwise.

Recalling how ages ago when he was still tailing him, Saito found that in Kyoto, Japan, the Emperor's Demons, a human organization, had been formed. Noting that it was ostensibly a religious sect, Saito found they were conducting experiments on turning vampires into demons. Confirming that he injected his own genes into the Ichinose family, and founded a competing organization, Saito affirms it was the Hyakuya Sect. Wondering whether Shikama Doji noticed the little barb he hid in that name, Saito explains "Hyakuya" means one hundred nights. It means one hundred nights for them, then a thousand, to a million meaningless nights spent by them after the First abandoned them.

Reacting with mild bemusement to Shikama Doji's words that he did not notice the name, and that nothing in this world means anything, Saito then seizes the First's neck through the prison bars. Demanding to know whether he is kidding him, Saito raises if everything is meaningless, then why does Shikama Doji have the single-minded determination to bring his son back. Instructing him to not drag them into his problems, Saito adds thanks to him, they have no reason to live, yet no way to die, so wonders what are they supposed to do.

"Are you kidding me? If everything's meaningless, why the single-minded determination to bring your son back? Don't drag us into your problems. Thanks to you, we've no reason to live, yet no way to die. What are we supposed to do, hm?."

- Seizing the First by the throat and rejecting his words that nothing in the world means anything, Saito questions their existence with no direction from him.

Suggested that they become independent for once, Saito laughs off the idea. Addressing becoming independent of the First's manifestations, Saito states Shikama Doji was quick enough to take advantage of his Hyakuya Sect. Even now he feels trapped within his grand plan. Releasing the First's neck, Saito announces he is sick of it. Not reacting to Shikama Doji having blue blood, Saito also stands indifferently to Urd's look. Upon hearing that they have already cut themselves free of Shikama Doji's strings, and told to just look and how they have him bound and imprisoned, Saito aims his hand backwards to fire three chains into the First.

"Ha ha ha ha ha! Independent of your machinations? You were quick enough to take advantage of my Hyakuya Sect. Even now I'm trapped within your grand plan."

- Laughing off the idea of being independent from the First as he mentioned.

Striking Shikama Doji in the throat with the chains, Saito orders him to shut his mouth. All that ever comes out of it is lies. Asserting that he will ask the questions here, Saito orders the First to answer them, nothing more. Speaking of one day when he noticed an anomaly in what he thought was his organization, an orphanage had suddenly been added. Considering the Hyakuya orphanage, having looked into it, Saito found it was experimenting on and killing thousands of human children. One day, several decades later, Saito notes a certain boy appeared on its doorstep. Detailing that he had a familiar face, and familiar name, with it being Mika, wondering what is he, Saito questions the First whether he finally found a vessel up to his high standards.

Accused of interrupting, with Shikama Doji mentioning Mahiru, then Shinoa, and Yu, and saying that Saito tampered with them all, he answers yes, but the First accounted for this, even planned on it. Although the First states he is not god, Saito answers he cannot trust him. With the request to listen to him, after Shikama Doji claims they have a mutual interest, Saito shoots a chain through him and reiterates he cannot trust him.

While Urd, along with Lest Karr, and Ky Luc react in a pained manner in response to the First's telepathic communication how when vampires die they become demons, with no will of their own, so they should listen to him, Saito deploys spell tags. Retrieving them from his jacket, and casting them into the air, Saito says to let them break that brainwashing spell. After his chain that was in the First clanks to the ground, and it is remarked that he is not an ordinary vampire anymore, Saito speaks of the spells at his disposal. Sharing how he took advantage of an organization Shikama Doji created as well, Saito mentions the Emperor's Demons and their spellcraft. Mentioning light spells, Saito also lists demon curses, to blood magic, and control of the divine punishment in order to weaponize the seraph of the end.

Unsure of who that punishment comes from, Saito then brings up how with Shikama Doji's angelic wings he almost seems angelic. Wondering where did he come from, Saito also questions who is chasing him. Pointing his finger, Saito queries who, and what is Shikama Doji. Summarizing that his goal is to bring his son Mikaela back to life, Saito reasons if he is the First's son then he must be the same species as him. While he cannot say if Shikama Doji is an angel or a demon, he does know that reviving one would take an unimaginably large price. One so large that other angels would punish the attempt.

Reminded of the First's vow he had them take, and deciding that now is a good time to defend the world from a potential second ruining due to Shikama Doji attempting to resurrect his son, Saito brings Urd in the agree with his stance. The world has already been destroyed quite enough in Saito's view, and they cannot let the angels come and punish it further. Hearing that nothing will happen to the world, Saito is informed that the price is seven sinful keys, and the lives of every last vampire.

"You know? I don't think we can allow that to happen. You did make us vow to maintain world order for eternity. We're bound to uphold that vow. Right, Urd?"

- A sudden interest in defending the world now that Shikama Doji's likely activities threaten it, so Saito will act to undermine the First.

Darkly recalling the mutual interest that Shikama Doji mentioned, Saito is asked are they not about ready to die, where they ought to be bored of living by now. Mirthful, Saito sees and questions is that what this is. Taking issue with the assumption that Saito would want to help Shikama Doji resurrect his son, and be one of the vampire sacrifices and so acquire the death he is supposedly after induces a reaction in him. Pleased, without a word, Saito launches a myriad of chains from out his back which plough into Shikama Doji. Deciding to have finally founds a meaning for his life, in response to Shikama Doji's assumptions, Saito declares he is against him getting what he wants.

"I've finally found true meaning for my life. I think I don't want him to ever get his wish."

- Where the First wants to sacrifice vampires to resurrect his son, Saito rejects the offer of death he had in mind and has a new goal.

Sorry to everyone, Saito speaks to Urd, with Lest Karr, and Ky Luc as well. Stating how he comes back for the first time in ages, Saito raises how now he has to make a selfish demand. Not responding to Urd asking when has he not made selfish demands of them, Saito rallies them with the speech that they cannot trust Shikama Doji's words. Something could happen to the world, and there is no guarantee that they will properly die if they listen to the First. Extending his hand, Saito suggests they resolve to live and prevent the First's son from being resurrected. When the world is stabilized, Saito adds a further incentive that he will ascertain a method of allowing them to die. Promising this, Saito asks for their trust.

"We'll need to stay alive for now... ...Stop Mikaela's resurrection... ...And stablize the world. I'll search for a way for us to finally die, I promise. Can I ask you all to trust me in this?"

- Directives to Urd, Lest Karr, and Ky Luc, all the undermine the First.

Finding that Urd will support him, Saito keeps his hand there as he is welcomed home by Lest Karr, with Ky Luc also agreeing with his plan. Repeating that they will find their own way to die, there is then the matter of interrogating Shikama Doji thoroughly.

Transported in the back of a truck, Saito has noticed Shikama Doji's expression as he lies nailed to the floor. Wondering what is so funny, Saito details how Shikama Doji is pinned, helpless, and has no hope of victory. Then questioning whether everything is still going to his plan, Saito adds if that is the case then they will put a stop to it.

"What's so funny? You're pinned. Helpless. You've no hope of victory. Or, what? Is everything still going according to your plan? If so, we'll put a stop to it."

- Transporting Shikama Doji and curious about his state.

Notably angered at Shikama Doji's content smile, Saito would like to know what is so amusing. Hearing Shikama Doji speak aloud about how who he is addressing's usefulness is over, and everything is going as it ought to, Saito focuses on the devour part that was said. Questioning who is to be devoured, Saito asks what does Shikama Doji mean.

Mount Fuji Arc
Having moved the First's cage inside a building, Saito stands within it. Where subduing the Demon Army soldiers of the now conquered Shibuya is left to the vampire progenitors, Saito awaits Hyakuya Sect members directed by Basteya to establish defensive sigils. Upon their activation which affects the prison, Lord Rigr is informed they are complete.

Stood over Shikama Doji who remains nailed to the floor of the prison, Saito is expressionless. Speaking how he is going to look into his past, Saito tells the First he will discover what he wants to protect. Also meaning to learn about what his ultimate goal is, Saito states he is then going to destroy it.

"I'm going to look into your past... ...First. I will discover what you want to protect... ...What your ultimate goal is... ...And then I'm going to destroy it."

- Informing the restrained Shikama Doji what his intent is, and apparently able to access his past memories.

Kneeling down, Saito continues to say that is the only way they have of escaping this curse that is Shikama Doji. Placing his hand near the First's head, Saito is cautioned by Urd to be careful which he reacts to. Proceeding, Saito means to go to the past.

Standing over Shikama Doji who now has cables attached to his head, Saito asks the First whether he is ready. Intending to poke around inside his mind, Saito grasps Shikama Doji's forehead and turns him to leave his neck exposed. Opening his mouth to reveal his fangs, Saito moves in.

Having placed his finger into the First's skull, evidently Saito had successfully viewed the memories of Shikama Doji who remained pinned in his prison. It is possible that Saito had seen that Sika Madu's lifespan went back to when Dinosaurs were the dominant species on Earth, which was one of several Satellite Kingdoms across various planets. Details such as a Seraph Civilization being formed on Earth, where beings including Homunculus' were involved in the Tower of Babel project to return seraphs to paradise where God was situated may have also been viewed.

This may have been the first time that Saito would see that Sika Madu's son, Mikaela was alive, along with a named homunculus called Yu. The possibility that the actions of an angel who had some similarities to him, namely Paimon, was seen is also likely. That Sika Madu had created Mikaela and stored utensils notably similar to Sinful Keys that he had been gathering would be striking details for Saito to learn about.

The destruction of the seraph civilization including the angels who appeared like humans by trumpet armed seraphs accompanied by a six-winged angel was an event that could have also be observed. That Sika Madu was left cursed as an undead to burn for eternity would be something that affected Saito. Since Sika Madu experienced what he did because he desired to resurrect seraphs who had perished from a species affecting plague, this would be something that also resonated in Saito.

What Saito saw for certain was Yu the homunculus bringing the first humans seen on Earth. The light-based spirits of angels flying into the human children may be able to be discerned by him. Physically there in the memory where he is able to access it, Saito crouches in thought as he considers the collective scenarios he is very likely to be up to date with. After a pause, Saito speaks aloud how if this is true then Sika Madu has spent all these eons fighting all by himself.

"Then, if this is true... ...You've spent all these eons... ...fighting all by yourself?"

- Viewing the memories of Sika Madu and what he experienced as an angel among others.

In the memory Saito regards Sika Madu who has just finished commenting on a human child resembling Urd and a human with parallels with himself. Making no comment on the humans, Saito has physically moved himself to the First in the memory. Regarding him, Saito progresses from glaring to addressing how the unresponsive memory of Sika Madu is still fighting for them even now.

While the memory of Sika Madu spoke how human lives where short, and so the angels without memories inside them may find happiness, Sairo concentrates on the First himself on how he has been here struggling. Livid at the idea, Saito shouts in outrage how Sika Madu has been dealing with this all by himself the whole time.

As Sika Madu mentioned how he is not going to give up on everyone and will resurrect them all, Saito found himself experiencing emotion. With tears streaming down his face, Saito was surprised to find he had them. Speaking how he does not remember any of this, Saito notes he is crying. Giving some thought as to why, Saito wonders does he still have his angel memories somewhere.

As Sika Madu interacted with the homunculus named Yu at the time, Saito also responded to a sound a child made. For his focus on Sika Madu it was also seemingly the first time Saito noticed that a child had approached the coffin containing the corpse of Mikaela. That the child was speaking to it was apparently not something initially noticed by Saito.

For his method of accessing memories, it is not known if Saito was accessing these ones the same time as Yu and Mika were from their location in the Sea of Trees around the base of Mt. Fuji. It is also unknown, though is a possibility that Saito would have overheard Mikaela's plan with the homunculus named Yu. From within the body of a human, Mikaela intended to hide his spirit there. The homunculus would assume his physical corpse form and so Sika Madu would never be able to resurrect Mikaela as his soul was elsewhere in the body of a human.

If he learned this, Saito would possibly have access to information that Shikama Doji didn't. He may have also seen Yu the homunculus, in the form of Mikaela's corpse scatter the sinful keys where Sika Madu had caught one. Where they were of major importance, it was all the more notable on account that Saito has Shikama Doji physically captured before him.

Evidently, Saito had learned that Yu was approaching the Demon Amy headquarters. Having moved to a large spacious room, Saito alone sits on a throne as other vampires flank him on either side. On Saito's right stands Urd and Lest Karr. To his left he has Ky Luc and Basteya in attendance as they receive Yu.

At ease on his throne, Saito's gaze is fixed upon Yu who has entered the room. Changing his expression to a more welcoming one, Saito comments what an unexpected guest. Saito asks Yu why he is here.

"Well, well! What an unexpected guest. Why are you here?"

- Finding that Yu has arrived to the Demon Army headquarters.

Natural abilities
Compared to a human, Saito as a vampires has supernaturally powered speed, physical strength, and senses as well. As a noble, Saito has the ability and permission to turn a human into a vampire. This was exercised on Ferid, where his blood has also been used to turn Crowley. Being a former second progenitor, Saito has renounced his title but lost none of the strength his rank involves. Where ranks ascending to one indicate strength, Saitō was already among the most powerful vampires worldwide. As vampires require blood to sustain themselves, Saito's capabilities were all the more potent after consuming it. In drinking from a human with a demon, it is implied that Saito can supplement his strength by draining their essence too.

Having displayed great speed, Saito was capable of dodging most of Urd's sword slashes. It was a testament of his skill given that Urd was also a second progenitor, and so another extremely powerful being. At the time there was a comment from Urd who noted Saitō had gotten slower than before for unknown reasons. Regardless of a possible taunt, accurate observation or not, it still did not stop Saito holding his own. Furthermore, Saito in fact was fast enough to strike Urd with one of his chains. Additionally, in fleeing, Saito was quick enough to do this, and gain a lead where Urd felt he could not pursue him.

Reflexes and having a quick reaction time are of benefit to Saito. Able to react in time to intercept an attack from Urd when he was moving at speeds fast enough to swiftly reach Ferid's mansion, he was able to seize his fist. In Catastrophe book 6, Saito came under attack from Mahiru after her transformation into a vampire. Where she also had the Shikama Dōji scythe, a Cursed Gear weapon that can inflict fatal injuries to vampires, Saito is capable of blocking it with just two fingers. Similarly, when Guren was drawing upon demon power, Saito could then also prevent the blade from making contact by holding it with his fingers. His reflexes allow him to grip would-be lethal weapons, in the capable hands of other supernaturally strong combatants.

The strength afforded to him allows Saito to strike someone with the force to break bones such as the neck, and rupture internal organs. Those who are capable of regenerating from such injuries need time to recover from the impacts. Barely any exertion is required to deal serious wounds, in drawing a hand across third progenitor Lest Karr, he could inflict cutting-like injuries. Cleanly slicing him apart, Saito's hands alone were lethal tools to overcome powerful foes.

As seen after being severely injured by Ferid using a Sinful Key, Saitō also possesses extreme physical durability and endurance even for a vampire. Being strong enough to survive having the majority of his body obliterated, rendered incapable of regenerating the damage right away due to the key's powers, Saito was still able to move around and escape to safety to momentarily hide from his enemies and rest. Upon being confronted by Ferid and Crowley, Saitō was shown to nonetheless possess sufficient speed and strength in his incredibly weakened form to fight, out-pace, and physically restrain Ferid.

Upon being located by Urd, Ky Luc, and Lest Karr, it was theorized that in order to properly capture him, the only "safe" way to do so was to completely destroy the entirety of Saitō's skeletal structure, rendering him partially dead. Further emphasizing the fact that, even in his weakened state, both progenitors would likely have no chance of capturing him, and he could easily kill them both regardless.

Through some means, likely his senses on account of being a second progenitor, Saito is aware of activity from afar that others are unable to make out. Where third progenitor Krul could not sense them, Saito knew that Urd as well as many nobles had arrived. This was not limited to beings, from his location within a building, Saito could also make out that a fleet of ships were incoming as well. Able to perceive more than what physical senses would allow, Saito could discern that Mahiru-no-Yo had manifested and was nearby, where as a demon they are invisible to all. Able to sense the awakening of a long dormant demon, Noya, he could also physically locate individuals. Knowing where Guren's friends specifically where, and what their state was, Saito could also have a chain emerge from Kimizuki some distance away.

Spell Tags
Keeping many spell tags on his person, often within his jacket, Saito uses physical ofuda to create both illusions, and nullify magical effects from others. Although some spell tags can be used offensively, where they can create minor explosions, dangerous more so when many can be deployed, Saito almost always uses his for-support purposes.

Many light flickering spell tags could be cast into the air which ended what Saito called a brainwashing spell from Shikama Doji. Where the First's voice harmed those he was communicating telepathically with, Saito was aware of how to overcome it and did so successfully via this magic.

"I took advantage of an organization you created as well. Your Emperor's Demons and their spellcraft. Light spells. Demon curses. Blood magic. And control of the divine punishment... In order to weaponize the seraph of the end."

- The source of his magical based abilities, some more devastating than others, and all potent.

From his confinement in a vampire prison, which had magical restraints, Saito could evidently pass spell tags that were unaffected by the particular magics of that contraption. Remarkably, Saito could generate a spell tag creation of himself. Simultaneously, Saito was able to inflict the illusion that the prison had been destroyed to a third progenitor vampire. The manifestation that rose up from the seemingly ruined cage could also use Saito's chains to strike through vampires, and also speak exactly as Saito would do. Seemingly vanquished, clapping its hands together resulted in the puppet like substitute's disappearance.

Bodily Modifications
Modifications to his structure have increased his strength, as Urd felt when he proved able to fight on par with him, another second progenitor, implying that he was once weaker than Urd but with his modifications, he is as powerful as he is. Upfront that he has had help from humans, Saito has also drawn upon experimentation from various human experimentation organizations, namely the Thousand Nights, but the truth for this is unclear.

Where he himself was the test subject, Saito's body appears to be a chimera where instead of a collection of various animal parts, it is a combination of manipulatable chains, a black mist like substance, and a regenerative flesh like material. Feasible that Saito's clothing can be generated when the material is cut, it seems very much a case that Saito is human in appearance only, again due to bodily modifications, then not even a vampire on the inside anymore. Able to turn into smoke and dust, injuries that release this substance from his body will detrimentally affect his attacker.

"Very impressive, indeed. My poisonous mist should have paralyzed you by now… Don’t tell me you’ve been holding your breath this entire time?"

- Catastrophe Book 1 Chapter 3, page 62

Chains
Where other vampire opt for swords that can drain their own blood to enhance their physical prowess further, Saito notably uses a very rare weapon, a chains system. Dexterous at using them, Saito can have a chain fire towards a foe's face, then wind past to barely scrape the skin as a warning. Unlike a sword for instance, chains do not need to be held, and in appearing from Saito's back they can attack and defend without any movement on his part. Behaving as if controlled by his mind, Saito has mentioned they are cursed, and so magically controlled. In a fight against Guren they were covered with fuda, so may be able to be enhanced further.

"Isn't it amusing? It is a curse that I have been working on for centuries, with human help."

- Saitō to Urd Geales.

Far from a cumbersome, hard to use, or requiring effort to swing choice of tool, one chain alone is (especially with the sharply pointed tip) a remarkably functional weapon. They effectively serve as spears that can strike from any angle. Lashing across a limb can cut it right off. Exceptionally fast, and striking with some impact, they can stab straight though a targets head. True to the spear comparison, one drawback is the impact is so strong that in the event it does go through the target, and not staggering them in such cases, the chain does not stop a target continuing their path towards him, as Ky Luc demonstrated.

One chain alone makes for a weapon that can wind round to avoid being blocked against, with the power to cut through bone, and has an extendable reach so Saito does not even need to draw close to an enemy and so not risk damage to himself. Where it can rapidly appear to jab, disappear and repeat from a different angle, the elements of surprise, and uncertainty come with the weapon. One alone has these benefits, yet Saito uses multiple chains, and more often than all at once as well. Seemingly not needing to aim, or focus on who to target, it is more like each chain will leap into a target to defeat them all at once. A barrage of them can mow down many targets instantaneously, where with their speed there is not chance to react, let alone acknowledge the situation.

Latching them onto a wrist for example, a remarkable precision can allow Saito to restrain specific targets. Wrapping them around someone's waist, he can lift them up as Saito done when displaying Shigure whose arm has been dismembered. Should a limb of his own be cut off, it seems a chain will automatically be connected with the rest of his body and draw it closer in order to be re-connected. Strong enough to hold his head up, Saito could have that positioned above his body via the chain connection. From his feet, Saito can have chains hold him in place on a ceiling.

It was displayed how a stream of them out of his left hand can be formed into large shapes. A great many chains, far more than what could physically fit into his body, can intricately form into a star inside a circle, a pentagram design. Once chains are stabbed into human hosts, this construction can capture demons. Used in conjunction with demon powers, Saito's chains can reach targets of his choice including the First who is in his own demon realm. Firing a chain into one human can have it appear out of another human in the physical world. Shooting a chain into Shinya, where Kiseki-o's transportation related coffins in the demon realm were likely used, the chain could emerge from Kimizuki back in the physical world. This can be used for communication where it is able to relay Saito's voice for him to administer plans.

His chains also allow him to absorb the life force of others if they come in contact to increase his power. A requirement seems to be that the chains need to stab into someone whose strength is to be sapped. Coinciding with a ritual, the chains apparently played a sizeable role in allowing them to be coated in entities resembling beasts of the apocalypse. The summoned beasts' heads consisted of a draconic-like being, a lion, wolf, bear and a goat heads.

"Isn't in impressive? Though it's all smoke and mirrors, I'm afraid."

- An account of what his beast of the apocalypse resembling power is.

The smoke and mirrors comment spoken to be deceptive, Saito directed the beasts upwards, where the chains propelled themselves at the First in order to skewer him.

Seraph of the End: Guren Ichinose: Catastrophe at Sixteen
The following quotes are from the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen prequel light novel series.

Book 1
From Book 1:

"My name is Makoto Kijima. I belong to the Thousand Nights."

- Saitō to Guren.

"I don’t have a real name."

- Saitō to Guren.

"War. It won’t be gods who spread this virus. It will be man. Humans. And ones that you know very well. The Hīragi Clan."

- Saitō.

"Checkmate. When you meet your maker, tell him it was pride that was your downfall."

- Saitō.

"Just my luck. I picked the worst spot to land. There’s only seven people on the list of dangerous targets at this school, and I’m stuck handling two of them."

- Saitō.

"Haha! Have it your way. But you realize that Mahiru is still in love with you, don’t you? The only reason she grew so strong, and betrayed her own family, was so that she could return to your side. It was very brave of her, don’t you think? All these years she’s remained true, working hard to be reunited with you. Don’t you think it’s time you rewarded her devotion? All she wants is for you to hold her again…"

- Saitō to Guren.

Guren Ichinose: Catastrophe at Sixteen Book 4
From Catastrophe Book 4:

"Uh oh, it looks like the demon’s already here. Guren gave in sooner than I thought."

- To no one in particular.

"Impressive, impressive… It’s made you stronger than I expected. Much, much stronger. How do you like the demon’s curse? How does it feel to give up being human? Does it feel good?"

- Saitō to Guren.

"By the way, how long are you able to stay in control of yourself? How many minutes are you human and how many minutes do you go berserk?"

- Saitō to Guren.

"Do you really have time for this? There are many more desires you need to fulfill. More people you want to impress. You have to show everyone how strong you’ve gotten and make them bask in your glory. Remember, you’re strong now. So very, very strong. And it feels good. That’s why you gave up your humanity. Just to feel this pleasure. To fulfill your desires. That’s how you grow more powerful. Stronger, and stronger, and stronger."

- Saitō to Guren.

"Saving your friends was just an excuse, wasn’t it? You told yourself you were giving up your humanity in order to protect others. But I know the truth. You needed an excuse to justify taking the next step forward. But it was a lie. Just an excuse. The truth is you couldn’t resist your desires. In any case, you’ve given up your humanity, and it’s time you enjoyed yourself. Go while you may. You don’t have any to waste on me."

- Saitō to Guren.

Guren Ichinose: Catastrophe at Sixteen Book 6
From Book 6: "What would you do if I said I was [Mahiru’s] new boyfriend? …Ah, you don’t seem to be very angry, do you? Don’t worry, though, I’m not her boyfriend. She’s a bit too scary for my—"

- To Guren.

"It’s a punishment sent down by God to chastise mankind for its insolence. But now there are foolish humans attempting to utilize it to create a weapon, never pausing to consider it might be put to more productive use."

- Saitō to Guren about the Seraph of the End.

"The outcome won’t change, but still you wail and gnash your teeth. You put up this pathetic resistance, even though in the end you’ll still make the same choice. But the kinder and more human you are, the deeper the despair into which you will fall, and the greater the strength you will acquire."

- Saitō to Guren.

"I’m a human."

- Saitō to Guren before abruptly revealing he is a vampire.

"Don’t say that. Your speed just now was breathtaking. Just what you would expect from a progeny of Third Progenitor Krul Tepes. You’ve only just become a vampire, and already you have enormous strength."

- Chapter 4

Seraph of the End: Vampire Reign
From the Seraph of the End: Vampire Reign manga:

"A good question. All vampires hate their 'parent' at one time or another. Almost like how human children go through a rebellious phase. Oh! Has Ferid said anything about me?"

- To Krul after she asks if he is after the first progenitor.

"Time, huh? Is there much of that left for this world, I wonder?"

- Contemplating to himself.

"It's about time. Have I finally managed to make you see me?"

- The response to the First saying they will have to punish Saitō.

"But you came to my prison anyway. You do want to talk to me. You have questions you want to ask."

- Engaging with Lest Karr after asking what Urd said, and hearing that it was not to speak with him at all.

"Boy, Urd sure likes keeping the dedicated ones."

- Reflecting on Urd after Lest Karr just avoided his chains.

"Aha. So that's how this is going. A powerful attack, but it takes time to charge. I'd best dodge."

- Taking a moment to regard Lest Karr's "Burst, Heaven's Fan" power being generated, and his response to it.

"Ah, Urd. You've truly been blessed with good companions."

- His thoughts on Urd around Lest Karr and Ky Luc.

"But you already know what I'm doing. I'm getting revenge... ...for the First betraying us."

- Sharing his motives with Urd.

"Today! Is the day! We surpass you!"

- His response to being told to die after being struck by Sika Madu.

"At that point... ...You changed your tactics. You'd promised us eternal life... ...But then you discarded us without a second thought."

- Recalling when Rigr with Urd were human and in prison where they were found by Sika Madu.

"But who does that punishment come from? And considering your wings, you almost seem angelic. Where did you come from, hm? Who is chasing you? Who, and what, are you?"

- Questions on who enacts divine punishment, and observations of Shikama Doji.

"Devour? Devour who? What do you mean?"

- Unaware that Shikama Doji is telling Asuramaru to let Yu consume him within a demon realm.

"That's the only way we have... ...Of escaping this curse that is you."

- Referring to Shikama Doji as a curse, he intends to ruin his plans.

"Are you ready, First? I'm going to poke around inside your mind."

- Speaking to Shikama Doji who remains imprisoned with cables attached to his head.
