Kaburagi Akira is a seemingly normal high school student at the time that Mina Tepes creates the Vampire Bund.

Akira is confronted by Meiren, and Akira begins doubting Mina. He finds out about Mina kidnapping the Prime Minister's grandson and confronts her about it and about the fact that vampires have infiltrated the school. She says that the vampire society rests on her shoulders and that she will do whatever necessary to make sure that the Vampire Bund plan is fulfilled. After hearing this, Akira teams up with some of the kids from school to eradicate the vampires inside the school.

Akira's curiosity about the concept of eternity leads him to ask Mina questions that are difficult to answer. Though it may sound promising, eternity is not without its harsh realities.

Killers-for-hire stalk Akira, and the werewolf's inability to transform puts his life in jeopardy. Meanwhile, Mina raises the stakes of her wager after a particularly unpleasant test of her purity.
