人外教室の人間嫌い教師

Rei Hitoma left his last school after a traumatic incident and now openly dislikes people, yet a job listing for a teacher who truly cares about students still pulls him to Shiranui Girls Academy, hidden in the mountains. His new class turns out to be demi-humans who have gathered there to learn how to become human. Kyoka Minazuki is a mermaid, Isaki Ogami a werewolf and Sui Usami a rabbit girl, and every earnest question they ask about humanity lands on a man who has given up on it.
