Saitō

Saitō (斉藤, Saitō) 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.

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 and calculating and goes to great extents to hide his true strength and identity. While facing off with Guren in First Shibuya 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 or Mahiru, even after Mahiru becomes a vampire. He also acts exasperated and tired when their attack on the school gets off schedule.

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 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.

History
Saitō was a second progenitor among the vampires, but he later gave up his seat and reappeared as an assassin for the Brotherhood of a Thousand Nights.

Book 1
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. 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 blantanly 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 his body was his own that he volunteered on his own for experimention. 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, he 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 experiement 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.

Book 3
In chapter 3, 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 lights herself on fire, and firefighters tackle her.

Saitō appears and approaches the camera before the footage is cut.

Book 6
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. He asks Saitō to kill his servants and join him.

Story: Vampire Reign
Thus far, he only appears in the flashback while taking Yu to the orphanage in chapter 22.

Natural Abilities
Being a vampire, Saitō is naturally far stronger and powerful than any human.As a vampire, he has immortality, eternal youth, immense strength, and rapid regeneration.

Being a former second progenitor as well as a member of the Progenitor Council, he is one of the most powerful vampires worldwide. He is also stronger than vampires who are of a lower rank.

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

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 obtaining strength equal to a Third Progenitor, she's still unable to land a single hit on him.

It should be noted that he has yet to display his abilities as a vampire aside from slightly-greater-than-human strength and rapid regeneration.

Unknown Abilities
Saito 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.

Weapon
In the light novels, he uses chains covered with fuda and smoke coming from his body to fight Guren Ichinose.
