Tetsuo is not shy at all and introduces himself, on the other hand, Sakie is a succubus, and is afraid to hurt someone with her powers, that’s why she refrains from contact with other persons as much as possible. Their first encounter is bitter, and Sakie thinks he is just curious about her.
Days later, Tetsuo tries to apologize with Sakie, but ends up rejected once again. At that moment, a new student approaches Tetsuo, she is Hikari Takanashi. Hikari says a student is not feeling well and needs help.
Tetsuo is confident he can help; all he needs to do is take a good look at the student expression to find an issue. However, this case is completely different, Kyouko Machi is a dullahan and her head is separated from her body.
