Akira Inugami is a werewolf and a transfer student who wants nothing more than to be left alone. His new homeroom teacher, Akiko Aoshika, cannot square what she saw the night before, a gang beating this same boy half to death in a park, with the unmarked student now sitting in her class. Placed alongside the school's worst delinquent, Inugami keeps his nature hidden while bullies and street gangs start circling, and the violence around him escalates.
