Akira Inugami is the new student at a school where his placement in the same class as the notorious troublemaker and gang leader sparks concern among the principal and teachers. Meanwhile, Inugami's homeroom teacher, Aoshika, is puzzled by a bizarre incident she believes involved Inugami being savagely attacked and killed the previous night, only to find him unharmed the next day, denying any involvement. Unbeknownst to Aoshika, a monstrous werewolf-like creature intervened, decimating the thugs who targeted Inugami in the park.
