Saitō

Saitō (斉藤, Saitō) was formerly a second progenitor of the vampires and also served as an assassin in the Brotherhood of a Thousand Nights, later referred to as the Hyakuya Sect.

Appearance
Saitō is shown to have the appearance of a young man with a gentleman-like approach. He has short clean-cut black hair with bangs and dull black eyes. 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.

Personality
As seen by the single appearance he has made, Saitō seems to have a cold sense of humor and attitude towards others, perhaps this being due to his nature as a vampire.

He is secretive and patient, going to great lengths to hide his true strength and identity.

He treated Mikaela Hyakuya gently and gave him money for ice cream. However, he treated Yūichirō Hyakuya with a cold nature, holding him against his will as he brought him to the orphanage. He also bluntly stated that Yu's home went up in flames and was also so hated by his own parents that they tried to kill him. Saitō then stated that in the Hyakuya Orphanage, everyone there was just as unwanted him therefore he would have a big, new family. It is difficult to ascertain his true nature.

History
Saitō was a former second progenitor among the vampires, but later due to unknown reasons he gave up his seat and became an assassin for the Brotherhood of a Thousand Nights. There, he worked with Mahiru Hīragi in the experimentation of the seraphs. They shared similar interest in opposing the Hīragi family itself. He delivers Yu to the Hyakuya Orphanage where Mika and Akane live on the night of the Apocalypse.

He is the one who convinced Mahiru to join the Thousand Nights, and later he betrays them after she does.

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.

Saito from the Thousand Nights appears and approaches the camera before the footage is cut.

Book 5

Book 6
Guren returns to his apartment to see Saitō lounging on his sofa. They fight, and Guren accidentally cuts off Saitō’s arm. 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. He is presumed to be stronger than Lest Karr and Krul Tepes due to his higher ranking in the council.

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.

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