Jingai Kyoushitsu no Ningengirai Kyoushi

My name is Rei Hitoma, and I call myself a misanthrope because of my disturbing past. I took a teaching job in the mountains hoping that I’ll get a quiet and a healing life. But I ended up at a school of demi-humans who wanted to become humans. A mermaid, a werewolf and a rabbit are now studying to become human. My job is to teach them how to become a human but also they have to learn some things too. This isn’t another world or rebirth story, just a strange school and its usual class.
