This one sneaks up on you. It hands you a man who has decided, with evidence, that he hates people, then makes him answer a job listing asking for a teacher who truly cares about their students, and you watch him fail to be as cold as he insists he is. Rei Hitoma's cynicism isn't a punchline here, it's a wound, and the demi-human kids in his classroom keep poking it by wanting exactly the human world that broke him. There's no spectacle, no arc escalation, just classroom light and small conversations that land harder than they should, the Interview with Monster Girls lane but with a teacher who needs saving more than his students do. The animation is plain and the first two episodes take a while to find the tone, so give it three. Then it's the show where a misanthrope learns his own lesson.

Rei Hitoma swore off humanity after a traumatic event shattered his faith in people, but a job posting for a caring teacher pulls him back into the profession anyway. He takes the position at a remote mountain school hoping for a calm life, only to find that his classroom is filled with demi-humans, from mermaids and bunnies to werewolves, all hoping to learn how to become human. What starts as just another paycheck becomes something deeper. Rei's cynicism clashes with his students' hopeful determination to understand humans. As he explains human behavior and social customs to them, their sincere questions and dreams begin to reveal the contradictions in his own outlook. Mixing comedy, fantasy and slice-of-life moments with real emotional weight, the story frames the classroom as a chance for teacher and students alike to heal.
