Shaped by experiences that left him weary of human relationships, Rei Hitoma openly dislikes people. Seeking a quiet, uneventful life, he accepts a teaching position at a secluded school in the mountains, only to discover that his classroom is anything but ordinary. The students under his care are demi-humans who have gathered there with a singular goal: to learn what it means to become human. Despite his disillusionment, Rei finds himself responsible for explaining human behavior and social norms to mermaids, bunnies, werewolves, and the like. As his students earnestly struggle to understand humanity, their questions and aspirations gradually expose the contradictions in Rei's own beliefs.

Bats & Terry are the two tough guys in the school. They don't take crap from anyone, not even teachers.

When they rescue one especially pretty girl from a gang they fight over her, but it's all friendly and they both recognize that she has some scars. The police hassle them and yet admire them when they break up the gang. Oh, and they're the star pitcher and catcher for the high school baseball team!
