Isaya Shoto

Isaya Shoto (菖藤 依早弥)is a 2000 year old pureblood vampire. He had just recently woken up from a 50 year slumber.

Personality
Isaya's personality is one that is very calm and collected. Isaya thinks things out rationally and has become very wise over the span of his long life. But it seems that he also has a comical side as shown with Kaien.

Background
Not much is known about Isaya's past, even though he is 2000 years old. But it seems that Isaya knew Juri Kuran before she passed away as he mentioned that she was like the very blaze of the sun. He is also old friends with Kaien Cross, which he seems to know that he has been raising Juri's child and also about his past as a vampire hunter.

Isaya also mentioned that he had a wife and children. They are believed to be deceased since Isaya's wife turned their offspring into humans. The offspring then turned old and passed away, leaving him all alone to become a spectator.

Isaya slept for 50 years prior to the story start and woke just shortly after the vampire party.

Plot summary
Isaya is the first pureblood Yuki Kuran and Hanabusa Aido visit on Yuki's mission. After hearing Yuki's speech, Isaya responds by saying that many people will view this as a reckless and foolish move; that he could be the one to chop off her head instead. She says that she knows that this could have been the worst option to take, but even if it saves one person then it would be worth it. With that said she turns to leave, but before she can, Isaya asks if she could really kill someone with that thing. After she reassures him that she could, she and Hanabusa leave Isaya's residence.

Once Yuki leaves, it is revealed that Kaien is also present. Isaya mentions that when he first met him, he thought that that he would turn out just like himself and become a 'spectator on the sidelines', instead of causing ripples in the surface. He also says that he has too much time and nothing to do, something common among the purebloods. Once Kaien leaves, he finally has his first meal from his awakening, served by his maid.

Powers
Like all purebloods, Isaya has an accelerated healing power and is immortal.
