Immorality

A new teacher is in town, but she's no ordinary one. She is a night dweller who preys on men. In return for orgasmic pleasure through intercourse, she devours their souls. Knowing about her cursed blood, a secret society hunts for her blood for the ceremony that is to come. Is Sayoko a human, a demon or perhaps a messiah? What connection does she have with the government? Who are these people that hunt for her blood? What are they trying to achieve from the ceremony?
