Saitō

Saitō (斉藤) is a former second progenitor of the vampires, who later acts as an experimental subject and assassin in the Brotherhood of a Thousand Nights (Later referred to as the Hyakuya Sect). He is the one of the main antagonists in Seraph of the End: Vampire Reign along with Ferid Bathory and Sika Madu.

He previously used the alias Makoto Kijima (木島真) while working for the Thousand Nights, and Urd Geales addresses him as Rígr Stafford (リーグ・スタフォード), Shikama Doji also refers to him as Rigr, indicating this is his true name. He is a second former member of the Progenitor Council.

Appearance
Saitō appears as a nondescript young man with a gentleman-like approach. He has short clean-cut black hair with bangs and dull black eyes. Like other Thousand Night members, he wears a business suit that includes a white dress shirt, black dress jacket and pants along with a black tie.

Despite being a vampire, he does not have pointed ears. Although he actually has red eyes, he wears colored contacts over them to hide his vampirism. He also keeps his fangs hidden.

Personality
Saitō has a cold sense of humor and attitude towards others, possibly due to his nature as a vampire. He is cold, calculated, and goes to great extents to hide his true strength and identity. While facing off with Guren in First Shibuya. He'd never revealed his real name at first but after the first attack in which they needed to retrieve Mahiru Hīragi, he appears worried when Guren threatens to overpower and kill him, despite the fact he is actually far stronger than Guren and Mahiru. He also acts exasperated and tired when their attack on the school gets off schedule. It is stated by Ferid that Saito was using Guren all along.

He treats Mikaela Hyakuya gently and gives him money for ice cream when out walking with him in the summer of 2012. However, he treats Yūichirō Hyakuya coldly when he drags the temperamental child to the orphanage on Christmas Day. He also bluntly tells Yu that Yu's home went up in flames and that Yu was so hated by his own parents that they tried to kill him. Saitō then states that in the Hyakuya Orphanage, everyone there was just as unwanted as him, therefore he would have a big, new family. It is difficult to ascertain his true nature.

His true objective is unclear, even to Mahiru Hiragi. All she knows for certain is that he is invested in the Seraph of the End project. He is the one who invites her to the Thousand Nights, which they both betray later on. Although he convinces her to become a vampire, he refuses to turn her himself. However one clear part of his motive seems to be his desire to be acknowledged and "seen" by his "Father" (Sika Madu) and seems to be one of his main goals and his main drive to all of his actions even states as he wants to restrain and capture him.

Although never 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, Saito was shown to have become excited and giddy at the prospect of his "Father" finally beginning to "notice" him.

History
A thousand years ago, Rígr Stafford was a second progenitor among the vampires who always accompanied the First Progenitor, Sika Madu. At some point, Rígr turned Ferid Bathory into a vampire, though he ended up abandoning him when Ferid didn't live up to his expectations. He was also a witness, along with Urd Geales, on the day Sika Madu disappeared with Ashera Tepes. Rígr later gave up his seat and reappeared in Japan as Saitō, working as an assassin for the Brotherhood of a Thousand Nights, and had experiments done on his body, to the point that his vampire nature was barely noticeable.

Rigr, along with Urd Geales, waited until Ashera awakened after being transformed into a vampire, pointing it out to Urd beside, him and commenting that now they are three. He feels things will be much more fun, and picks up on Urd's statement of them being superior beings to humans. When Ashera begins craving blood, Rigr tells him that he will get used to it, as it will never truly go away, and suggests to Urd that they will have to teach him how to deal with it.

Events of 2012
When Guren returns to his apartment after school with Sayuri and Shigure, he heads to the upper floors that has been converted to a training dojo by the Ichinose family. As he waits for the elevator, he is greeted by a man dressed in a suit who he assumed to be the owner, so the man goes along with his assumption. However, when Guren boards the elevator he notices something amiss by the elevator buttons, then realizes that the man is not whom he claims to be. Immediately, he concludes that the man could only be an assassin.

Soon afterwards, he and the man engages in combat. Guren manages to mangle the man's arm and land many blows on him that would prove to be fatal, however the other is not deterred. In fact, he hardly reacted to his would-be agonizing wounds. Black mist seeps out from his wound as his body is mutilated. Guren thinks that he is neither human nor vampire, but a sort of monster that resulted from some sort of human experimentation - a chimera. Later, the man introduces himself as "Makoto Kijima", an assassin from the Brotherhood of a Thousand Nights. His wounds heal at an incredible pace. He claims that he was there to offer Guren an alliance between the Thousand Nights and the Order of the Imperial Moon. Guren blatantly refuses their offer, warning the man that he will kill him. He starts counting down for him to retreat, in which the latter does so. In return, he too gives Guren a warning - a warning that he would regret not having joined the Thousand Nights. The elevator door closes and the man is gone.



Later another day, Guren sits in front of a small supermarket as he waits for Sayuri and Shigure to shop for ingredients. Nearby, he hears a little boy excitedly shouting for a man named "Mr. Saitō." He watches as the boy eagerly speak with the man for money to buy treats back for the others at the Hyakuya Orphanage. The man, Saitō, acts friendly and kind to the child, calling him Mikaela and giving him a 10,000-yen note. After the child has run off to the supermarket, Guren immediately recognizes the man in suit as the assassin from before.

He casually strikes up a conversation with the assassin about his identity and real name, in which the other replies that he doesn't have a real name. After refusing another offer from Saitō to join the Thousand Nights, he questions what the man planned to do with Mikaela, knowing that the Brotherhood carries out human experimentation. Saitō states that the Hyakuya Orphanage is run by the Brotherhood as a charitable endeavor, and that he'd volunteered his own body for experimentation. He reveals to Guren that the Imperial Demons run by the Hīragi family have begun studying forbidden magic, and that the Thousand Nights are trying to put a stop to them.

Once more, he offers to Guren an alliance to join them, in which 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 syndicate in the country. Guren asks for an hour to decide, but he is refused. In doing so, he once more turns down Saitō's offer of alliance. He warns the man that he would regret not having the Ichinose clan on his side. Mikaela soon returns after their exchange, commenting about Guren having a nasty look in his eyes to Saitō.

The assassin jokingly warns him to stay away from Guren, stating that he does not know him and may be a pervert. This compels them to immediately leave Guren afterwards. Guren ponders afterwards whether or not he had made the right decision in turning down his offer.

During the qualifying exams, after Guren decides to forfeit his match with Seishirō with Shinya's help, he notices a beam of red light high in the sky above the schoolyard. Before anything else, he quickly forces Mito and Norito 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. Dust and smoke rises up from the bombing, creating a smokescreen that masks their sight. Guren realizes that the war between the Brotherhood of a Thousand Nights and the Hīragi Family had begun. Recalling Saitō's words, the assassin had warned him the war would start in ten days, it had only been two days since the warning. Knowing Saitō has lied to him though he had expected it, he views the situation on hand.

As he is about to draw his sword to join the fight, a lone man floats down from the sky in the center of the schoolyard's temporary fighting ring, now abandoned. Guren immediately recognized him as Saitō. The assassin studies the carnage with a smile and states that everyone, the students, could all die. With Shinya and Seishirō alongside him, the former asks who the man is. Seishirō is infuriated and tells the assassin that he made a big mistake attacking the Hīragi family. Saitō comments that he hated noisy brats before attacking. Right before he strikes him fatally, Guren manages to kick Seishirō out of harm's way and out of sight. Quickly, he casts numerous spells for him to be able to deal with Saitō's attacks. Shinya, still present, is surprised and astonished by Guren's sudden display of admirable prowess. Afterwards when Guren threatens him, the two decides to work together to fight against Saitō in the meantime.

After they manage to pin Saitō in place, Guren explains to Shinya about his and the assassin's relationship and how they met previously, including the alliance he had proposed. As soon as this is mentioned, Saitō once more offers the alliance, this time including it to Shinya. However, Guren refuses and tells Shinya he could decide whatever he wanted, but he refuses to be controlled. With this, he attacks the man. The latter only calmly watches as Guren's blade descends to cut him through, stating that his body had been altered to resist such tactics. With that, his body begins to diffuse into mist as he prepares his chains to deflect Guren's attack. However, at the last moment he comments that it wouldn't be enough, and Guren's blade slices through the chains and into his flesh.

Soon afterwards, Guren slaps on a fuda and it explodes with energy. Saitō is surprised to see the curse eating away at him, bewildered at the effect and saying that his body had been altered to resist all Hīragi clan magic. Guren corrects him and says that he's not a Hīragi. Fear crosses Saitō's face as Guren tells him that the curse would consume him until he would be trapped for all eternity inside his sword. He calls for Guren to stop, in which he demands for answers and information. He tried to retaliate by activating a spell from his eye, but Shinya easily prevents it with a fuda.

Eventually, the man relents and explains that one of the students had betrayed the Hīragis, selling secret magics to the Thousand Nights and that the research project was an experiment they've been carrying out together with the student. He tells them that the Hīragi family was betrayed by someone important, someone who despises the Hīragis family and is higher than Shinya. Shinya immediately realizes who it is, Guren demands from Saitō who it is. The latter merely states that if Guren wished to kill him, he might as well get it over already. He tells him that his mission was almost complete, and that they were here to recover research materials and to pick up their "collaborator," and that his job was to simply keep both Guren and Shinya busy. With this, Shinya quickly runs off in a panic as he realizes the trap.

Soon afterwards, Guren realizes who the traitor was, Mahiru. Saitō comments that he had thought Guren would be more upset since she was his girlfriend, but Guren denies it. Saitō then continues to goad and chide at Guren about Mahiru, saying that the reason she had come so far in doing all of this was to return to his side. He tempts Guren with Mahiru, stating that with the two of them together, it would make a welcome addition to the Brotherhood. Guren then questions that if this was also part of his mission, to wait for this moment before extending an invitation once more to join them. However, they are interrupted soon afterwards when the Imperial Demon Army arrives. Guren realizes that everything had been set up by Mahiru, that no one would discover that she was the traitor and rather she was abducted by the Thousand Nights. Saitō then says that they were out of time, but Guren refuses to let him leave and that he would kill him if he didn't give him any information.

The assassin tells Guren that if he kills him, he would never see Mahiru again. Guren merely says that he was fine with the idea, saying that he did not grow stronger with the intention to see Mahiru again.

At this, Mahiru herself appears. They exchange words with each other, with Mahiru displaying her newfound powers with the research of cursed gears. After awhile when she starts to slowly be consumed by the demon curse, Saitō finally intervenes by wrapping one of his chains around her consumed arm, suppressing the power. He tells her that they were running out of time and that they must leave. She agrees with him, but Guren stops Saitō and asks what he did to Mahiru. As he attacks the man, Mahiru intercepts his strike, cutting through Guren's blade with hers.

When Guren refuses to come with them again, Mahiru then tells Guren there was something important she wanted to tell him. At this, Saitō seems to panic and tells her to wait, but she ignores him before warning Guren of the apocalypse and end of the world that would soon come around Christmas. Afterwards, she disappears through one of the smokescreens and leaves Guren alone with Saitō once more.

The assassin by this time acts tired and exasperated, saying that they have gone far off schedule. He informs Guren that if he wished to get in touch with the Thousand Nights in the future, he should go to the Hyakuya Orphanage and speak to the director there. Then, he promptly leaves.

Some time later, the 6 p.m. news shows the fire at an apartment complex. A disheveled woman in her mid-twenties with long, silky black hair steps out of the crowd and screams for Yuichiro. She screams about a demon and says the fire should never be put out. She says the demon child should be killed immediately. She dowses herself in lighter fluid, but firefighters tackle her before she can set herself aflame.

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 he uses his chains to pull the poison capsules from their mouths. When Saito notices Guren’s arrival, he steps back, and Guren slaughters the Thousand Nights soldiers.

Saitō applauds him and encourages him to give in to the demon’s curse. Guren cuts him in half, but It is only an illusion.

Saitō tells him Norito is holed up in the fifth-floor girls’ bathroom while Mito is in the audiovisual room. He says he will not be able to resist becoming a demon once he saves them.

Mahiru joins Saitō and then goes to the roof to torment Guren and his aides more. After that, they disappear.

Guren returns to his apartment to see Saitō lounging on his sofa. 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. He tells the Yu that the children at the orphanage are kind and will get along, but the boy says he cannot get along because his parents said he was a demon child which Saitō decides not to tell him that they weren't his real parents. He tells Yu that children are cuter when they are smiling which Yu replies he does not want to be cute.

Saitō tells Yu that if he wants to die he could open the door and jump out of the car, but 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. He then calls the director of the orphanage and says he is bringing a child of great destiny and a demon, but the director does not understand. Saitō thinks 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 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. Saitō brings Yu to outside the orphanage and tells him that the children could be his family, but Yu says he doesn't need one. Saitō remembers that he once had family members that were important to him, which would mean he would lose them.

Saitō wonders how many hours are left, and his phone continuously vibrates. He knows that they are reports about what is going to happen at the end of the world, but he does not look at them. He looks up at the sky and thinks about how he cannot save the world so he must plan for the future. Saitō smiles at Yu and brings him into Hyakuya Orphanage.

Post-Shinjuku Arc
Saitō first appears in the flashback, taking Yu to the Hyakuya Orphanage. He mentions that Yu's parents hated him so much, they tried to kill him, and Yu's previous home went up in flames.

Osaka Arc
He reappears where he visits Krul Tepes, who is sealed in a wall and starved for blood. He comments on how pathetic she has become, and though Krul does not recognize him at first, he says she should know him quite well. She then recognizes him as "the one who always tagged along behind the first progenitor."

After a flashback of events that occurred 1000 years ago, she comments that Saitō has changed a lot. Saitō asks if it has really been that long since he quit being a second progenitor and says he changed his name to Saitō, which sounds Japanese. She asks if he ordered Ferid to capture her, but he denies it and comments about the difference in power between her and Ferid. He says Ferid must have tried really hard to capture her.

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

Krul asks if Saitō is also after the first progenitor and says that all vampires despise him to some degree. Saitō says that is a good question and that all vampires go through a rebellious phase at some point. He asks if Ferid has said anything about him, only for Krul to call him Saitō's lackey. As if sensing something happening outside, Saitō says a fleet of ships from Russia have arrived with Urd Geales and a few nobility. He wonders it it is his son who has summoned the other progenitors.

Saitō notices a bleeding wound on Krul's neck, and observes that a strange ointment has been applied to it to keep it from healing. He mentions that a high ranked progenitor gives off a unique scent that attracts lesser vampires. He licks the ointment off the wound, but says that Urd already smelled the blood, and then figures that this was a trap for him. He contemplates whether or not to leave when Urd bursts through the door and goes right for him.Saitō stops Urd's fist, and is referred to as "Rigr Stafford" when asked if he is behind what's happening in Japan. Saitō greets him with a smile and dodges Urd's sword slashes. Urd says Saitō has gotten slow, though the latter remains unfazed and allows his arm to be cut off. Multiple spiked chains spring from it and towards Urd, who slashes them away except for one that pierces his neck and causes marks to appear.

When Urd demands what that was, Saito says that it's a curse he had been working on for centuries with human help. Urd claims that Saitō is no longer a vampire, to which the latter replies that remaining as a vampire is the reason why the first progenitor left Urd. Urd points out that Saitō was abandoned too, much to the latter's agreement. Urd then asks what Saitō wants to which the latter answers by asking him the point of continuously living century after century following the rules of a father who abandoned them. Saitō continues with saying that they are brothers coming from the same blood of the first progenitor, so Urd should not be interfering with him and tells him to leave. Urd refuses, so Saitō then lassos a chain around Krul and pulls her out of the wall to launch at him as a distraction. He sprints to the open door when Lest Karr shows up, but Saitō simply slices through him to get through.

Once outside, he makes his way through a garden, only to come to a halt by Ferid, who says that he has been awaiting him as its been a thousand years since they last met. Saitō tells Ferid that he has no time to chat as Urd would be following him. Ferid tempts Saitō to kill him though the latter is suspicious on triggering another trap if he tries. Ferid continues to tempt him, so Saitō lunges at him and pats Ferid on the head. He comments that he chose "an odd one" to turn into a vampire. Before he departs, Saitō tells Ferid that he will forgive him for this act, but won't do again next time.

Besides appearing in Mika's flashback on the day Yu first came to the Hyakuya orphanage, Saitō does not appear again in person until where he is seen standing atop the Sunshine 60 Building in Ikebukuro, Tokyo, holding two small cross-shaped daggers. Overlooking the devastated district, he muses aloud about how far the person has come in the last thousands of years and whether he still goes by "Sika Madu" or is now "Shikama Dōji". Saitō then asks aloud if his interference is disrupting that person's plan, before a suited person informs him that its time to go which makes Saitō wonder how much time is left for this world as he leaves.

Shibuya Arc
Much later in Ikebukuro, he, along with other vampires across the world, feel the First Progenitor's presence. Saito mentions it's been a long time but it seems it was recent, and today is the day that it begins. Still in Ikebukuro, at station east exit, commenting about the First Progenitor's interference with his plan. At the old Hyakuya Sect underground headquarters, he orders the researches to launch multiple missiles In what turns out to to be an attack on the aircraft carrying Urd Gaeles, Ky Luc, Lest Karr and Krul Tepes. Urd figures out that Saitō was the one who sent the missiles. Saitō is seen glaring at the moon as he wishes that Urd would die on this night. A suited man informs Saitō about the extent of damage to the aircraft. Saitō then decides to go to Shibuya, as he announces to the legions of the Hyakuya Sect, among them vampires, telling the army that today they are all going to destroy the Japanese Imperial Demon Army.

Saito is remembered as a second progenitor and member of the Hyakuya sect when Guren and Kureto are discussing Mahiru.

Standing amongst the ruins of Tokyo, near the east exit of Ikebukuro station, Saito 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 Saito wonders whether the first is being loud on purpose.

Moving to the old Hyakuya Sect underground headquarters, Saito walks before an fleet of missile bearing trucks. Informed by staff that a target signal as been acquired, Saito gives the order to launch a volley of target seeking rockets towards Urd Geales, Krul Tepes, 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, Saito 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, Saito intends to move his forces onward to Shibuya. Legions of the Hyakuya Sect are before him with Saito proclaiming that today, they destroy the Japanese Imperial Demon Army.

Having arrived in Shibuya outside the city walls and captured Yu. He orders his men to take him to the lab in Ikebukuro then destroy the Japanese Imperial Demon Army and capture the first, and strip the 'Sun God Aten and Michaela' from Urd and the first.

With his army having arrived at Shibuya, Saito stands with his eyes closed before being informed that preparations are complete and that the attack may begin at any time. Saito asks if everything is in order acknowledging that they are facing some powerful opponents including the first himself and several "family" members who bear his genetic material. Nevertheless he 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 Saito 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 Saito orders them to fire. As the operation occurs, Saito stands atop a wall and is revealed to others as being the one in complete control of this plan by Basteya Irclu.

Having made his way to the area where Mirai has been activated as a seraph, Saito uses six long chains from his back to murder the scientists there. He is stood directly behind Kimizuki and heard that Mirai is his sister and so he will have to treat it with care. Not answering Kimizuki's question of who he is, Saito is afraid he does not have time to speak with him right now. Saito then asks rhetorically what he means to Kimizuki, before questioning whether he should go to his sister. He does not turn as the first enters the room instead politely saying hi to Shikama Doji who is inside Shinoa's body and notes that it has been a while.

Standing opposite the first with Kimizuki and Mirai in between them, Saito 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 explaining that the years have been entertaining for him fortunately enough, very much so. As chains extend from his back Saito 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 Saito reaches his point that he could hardly wait to show the first what he is truly capable of, with an emphasis on making the first pay attention.

He and the first are joined by Basteya Irclu and another vampire suddenly crashing into the room where lord Saito hears that the unification spell is ready and they will begin at his command. Saito states it is good, proceed, and answers the firsts enthusiastic question as to what he will do simply replying that he is restraining them. Saito duplicitously agrees with the first's analysis that they are all so weak, claiming in honesty he is not at all confidant. Adding 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 Saito and he can now suspend himself off the ground. With the first having reasoned this, regarding how how powerful it makes him Saito judges it a good question but could not say. Curse marks have appeared on his face as he announces that he may as well test it. Asking whether the first thinks so but not waiting for a reply, Saito declares here he goes to his father. In response to Shikama Doji instead making a move towards Mirai, Saito immediately lashes out with a chain snatching their wrist and waits for the first to react.

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

With his head able to be raised, Saito insists that he would never do such a thing when accused by the first they would be his guinea pigs instead of theirs. As Saito's head floats above him like a balloon with a chain to his torso, he replies that he woke up in the morning and it was like this when queried on what happened to his head, asking 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 do not cut it, Saito's neck chain is sliced and he manages a smirk before a profusion of chains explodes from the opening in his neck.

These are directed to stab into the ground where the first is who sprints away from them and leaps through the glass exiting the building. The chains follow them, arching out onto the exterior. Shinoa with the first within is airborne possessing six seraph wings. Saito's head is reattached and he now has conjured before him an array of thick scaled necks ending in a range of animal heads with lifeless white eyes consisting 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, Saito only notes it's impressiveness. He attempts to assure the first that it is all just smoke and mirrors though before observing that their wings are as lovely as always, just like an angels.

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

With chains continuing to be used, Saito drily remarks on whether the first just got even more powerful, and that this is a problem to make his concern more convincing. Whatever trump cards Saito has, the first will not let him use then and Saito happily orders the full curse system to be activated when a scythe is flung towards him.

Maintaining the fight, Saito sees Guren join the battle. With his arrival and the first doubting the abilities of this trump card, Saito smiles. Commenting on the lateness, Saito states he nearly died. He enquires about the key and has one tossed to him from Guren above. Catching it, he explains to the first that according to his calculations and considering that the first still has not manifested their real body, then the three shining keys Saito possesses should be enough to seal the first away.

Considering the possibility that the first is correct on the extent of the speed, Saito springs into the air and states if he ate three more demons, what then. He betrays his allies Guren, Noya and Mahiru in the middle of the fight against the first and moves in to bite Guren. Saito finds his deception met with a double cross as he is struck with a dagger from Ferid, appearing through Jigenso’s portal upon Guren’s command. Appearing apprehensive hearing from Ferid that one key is enough to break him, there is a resulting large explosion.

Natural Abilities
Being a former Second Progenitor as well as one of the highest ranking members of the Progenitor Council, Saito was already among the most powerful Vampires and much stronger than vampires who are of a lower rank, although on his own admission, he is still far surpassed by Sika Madu, the First Progenitor.

His modifications have increased his strength, as Urd Gaeles noted when he proved able to fight on par with him, another 2nd progenitor and the current leader of the Progenitor council, implying that he was once weaker than Urd but with his modifications, he is as powerful as he is and they tie as the strongest Vampire with Sika Madu now a demon. He also instantly defeated the Third Progenitor Lest Karr, who is considered to be stronger than Krul Tepes.

He has displayed great reflexes and speed, managing to intercept an attack from Urd when he was moving at speeds vast enough to swiftly reach Ferid's house, the clash of strength that caused a crater to be formed, and dodge most of Urd's slashes, although Urd noted Saito has gotten slower than before for unknown reasons. When Ferid dared Saito to kill him, he instantly covered the distance between them and patted his son's head while he could not see his sword finger change. In Book 6 of the Catastrophe light novel, after Mahiru's transformation into a vampire, she attempts to kill Saitō with Shikama Dōji, but fails when the latter manages to block the cursed scythe with just two fingers. Mahiru notes that despite herself becoming a vampire and receiving the strength of a Third Progenitor, she is still unable to land a single hit on him.

As a noble, he has the ability and permission to turn a human into a vampire.

Unknown Abilities
Saitō can turn into smoke and dust and release chains from his body. He says this is from being experimented on by the Thousand Nights, but the truth for this is unclear. By using these abilities, he hides his true nature as a vampire. His chains also allows him to absorb the life force of others if they come in contact to increase his power. He is also able to summon beasts heads that consists of a dragon, lion, wolf, bear and a goat heads. Shikama Dōji described them similar to the beasts of the apocalypse.

Weapon
In the light novels, his chains covered with fuda and smoke coming from his body when fighting Guren Ichinose. In Vampire Reign, when fighting Urd, there are no fuda and the chains are enchanted. He also slash Lest Karr in half simply by making a sword finger.

 * "It seems the future head of the Ichinose Clan is no pushover. But my, such a temper… A person just happens to board an elevator at the same time as you, and you attack without giving it a second thought..."—Chapter 3, Pages 60-61
 * "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?"—Chapter 3, Page 62
 * "My name is Makoto Kijima. I belong to the Thousand Nights."—Chapter 3, Page 63
 * "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."—Chapter 3, Page 65
 * "Here, Mikaela, take this money. The supermarket’s right over there. I can trust you to buy the treats on your own, can’t I?"—Chapter 5, Page 91
 * "The kids at the orphanage all know me as their friendly Uncle Saito.”—Chapter 5, Page 91
 * "I don’t have a real name."—Chapter 5, Page 92

 * "The Thousand Nights is dedicated to ensuring our country’s future. You may not be aware of it, Guren Ichinose, but if Japan continues on the path it’s on, it will face ruin. The trumpets of the apocalypse are soon to sound."—Chapter 5, Pages 92-93

 * "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."—Chapter 5, Page 93

 * "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."—Chapter 7, Page 145
 * "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…"—To Guren, Chapter 7, Page 148
 * [Guren: "So the one who convinced Mahiru to betray her clan…"] Saito: "…was me. She told me how she still loves you. She wants to create a world where the two of you can be together. She said she would do anything to achieve that goal. Even sell out her own family."—To Guren, Chapter 7, Page 149

Book 4
Soldiers began pawing at Shigure’s clothing.—Saito ordering the Thousand Night grunts to rape Shigure, Chapter 2 "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." "…" Saito’s body finally vanished from sight. His voice, however, continued to fill their ears. "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." "…" "This is your chance. Save young Norito first, in the fifth-floor girls’ bathroom, and then Mito in the audiovisual room. If you go in that order, you’ll be able to protect them both. Once you do, you’ll understand just how incredible this power really is. It will consume you. You won’t be able to turn back, to shake how good it feels. Yesterday you were pond scum. Today you are god. You’re their savior. Once you see how good that feels, you won’t be able to resist becoming a real demon."—To Guren, Chapter 2
 * "Look at how big this one’s tits are. She’s hot, isn’t she? Why don’t we fuck her?" he’d said.—Suggesting the Thousand Nights rape Sayuri, Chapter 2
 * "You can try to chew through your tongues if you like," he said. "I’m pretty sure you both know how difficult it is to kill yourselves that way. The worse for wear you both wind up, the more Guren will be affected and the more powerful he will be."—To Shigure and Sayuri after he prevents them from committing suicide, Chapter 2
 * "I don’t really have a name," the man in the black suit replied. "But Guren refers to me as Saito."—To Shigure, Chapter 2
 * Saito laughed. "I’m trying to rape you, obviously. Okay, everyone, we’re running out of time. You better get started on this shorty as well."
 * "Uh oh, it looks like the demon’s already here," he said. "Guren gave in sooner than I thought."—To no one in particular, Chapter 2
 * "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?"—To Guren, Chapter 2
 * "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?"—To Guren, Chapter 2
 * "We didn’t make it to the final act, unfortunately, but what did you think of our little performance? That forbidden power feels better than you ever imagined, no? You were able to save your two followers from being terribly abused. The truth is I was hoping to injure these two lovely girls beyond repair. So that I could drive you even further into despair and teach you the sweet, sweet joy of revenge."—To Guren, Chapter 2
 * "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.

Book 6

 * He was sitting on the couch. He turned his head slowly toward Guren and grinned. "Welcome home, Lord Ichinose."—To Guren Ichinose, Chapter 3
 * "What would you do if I said I was [Mahiru’s] new boyfriend?" Saito asked back, grinning. "…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, Chapter 3
 * "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."—To Guren about the Seraph of the End, Chapter 3
 * "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."—To Guren, Chapter 3
 * "I’m a human," replied Saito.—To Guren before abruptly revealing he is a vampire, Chapter 3
 * "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."—To Mahiru, Chapter 4

Seraph of the End: Vampire Reign

 * "True, your old home did go up in flames. Not to mention you are now so hated even your own parents tried to kill you. But it's all okay now. In this orphanage, you'll find friends who're just as unwanted as you are. You'll have a big, new family."-- Saitō to Yūichirō, Chapter 22, "Taboo Krul"
 * "Needed or not, this will be your new home. It's the only place you can live. Welcome to the Hyakuya Orphanage, Yūichirō Amane."-- Saitō to Yūichirō, Chapter 22, "Taboo Krul"
 * "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 Saito. Does that have a nice Japanese ring to it?"--To Krul, Chapter 49, "Progenitor's Memory"
 * "What? You allowed yourself to be captured by Ferid of all people? You must be kidding. Like me, you are a child of the first progenitor. Ferid is merely a child of mine. There should be quite a difference in power. My, my. He must have tried really hard if he managed to capture you. Still... So this is his mansion? He has been this way since the day we first met... but goodness, he is an eccentric one."--To Krul, Chapter 49, "Progenitor's Memory"
 * "Me? Oh, no. I have no connection to Ferid at all. He was unable to live up to my expectations. So I discarded him ages ago... Ah well. Not that that is any different than what the first progenitor did to us. In the end, he was interested in only one child--your brother, Ashera Tepes. He ignored and discard all the rest of vampire-kind."--To Krul, Chapter 49, "Progenitor's Memory"
 * "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, Chapter 49, "Progenitor's Memory"
 * "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?"--To Krul about Urd, Lest, and the arriving vampires, Chapter 49, "Progenitor's Memory"
 * "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?"--Saito, Chapter 50, "Brothers in Blood"
 * "Isn't it amusing? It is a curse that I have been working on for centuries, with human help."--Saito to Urd Geales, Chapter 50, "Brothers in Blood"
 * "What do you want, living pointless century after century, faithfully upholding the rules set down by a father who carelessly abandoned us both? Oh, I don't need you to tell me. We are both brothers born of the blood of the same first progenitor, after all. So what say we stop interfering with each other? Okay? Okay. Now, leave Japan. This is my playground."--Saito to Urd Geales, Chapter 50, "Brothers in Blood"
 * "I certainly chose an odd one to turn into a vampire. I will forgive you for today. But next time, I will not be so generous to you and your games, Ferid."--Saito to Ferid, Chapter 50, "Brothers in Blood"
 * "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 Doji 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..."--Saito to himself, Chapter 68, "Saviors"
 * "Time, huh? Is there much of that left for this world, I wonder?"--Saito to himself, Chapter 68, "Saviors"
 * "Oho! It's your sister, hm? I guess I'll have to treat it with care."--Speaking to Kimizuki regarding Mirai as a seraph after having murdered scientists in the room with chains on his back, Chapter 80, "Lightning Over Shibuya"
 * "A good quetion. It's been at least, oh... 2,000 years or so, I'd say."--Civilly discussing the last time he saw Shikama Doji (note, number "2,000" used over words "two thousand"), Chapter 81, "Fallen Wings", page 3
 * "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, Chapter 81, "Fallen Wings" page 4
 * "Take the girl and run. Make your way towards Shinjuku. I have allies there. Find them"--Calmly stated point by point steps for Kimizuki to take with Saito allowing him to rescue his sister and revealing allies in Shinjuku, Chapter 81, "Fallen Wings", page 12
 * "The demon army was founded by the first for his personal use. Stay here and you'll only be experimented on further. Run quickly"--His view of the Japanese Imperial Demon Army, knowledge of experiments on people, and explaining this whilst his head is on the floor with only a chain connecting it to his body nearby, Chapter 81, "Fallen Wings", page 13
 * "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, Chapter 81, "Fallen Wings", page 14
 * "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, resulting in a huge mass of chains springing out into the first, Chapter 81, "Fallen Wings", page 15
 * "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, Chapter 81, "Fallen Wings", page 18-19
 * "It's about time. Have I finally managed to make you see me?"--The response to the first saying they will have to punish Saito, Chapter 81, "Fallen Wings", page 20-21
 * "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 Saito wants, Chapter 84, "Nativity of a Princess", page 8
