Akira Inugami just transferred into his new school. The principal and teachers fear what may happen because Inugami was placed in the same homeroom as the school's biggest problem and gang leader.
His home-teacher Aoshika is going out of her mind trying to figure out what happened the night before where she could have sworn she saw this same Inugami beaten by a large group of thugs in a park and then hit by a car. But somehow, Inugami, who denies everything of course, is alive and without a scratch attending his first day at his new school.
What the teacher Aoshika did not witness was a crazy werewolf-like beast destroy the thugs that attacked Inugami in the park.
