人外教室の人間嫌い教師　ヒトマ先生、私たちに人間を教えてくれますか……？

Rei Hitoma is a former schoolteacher and a self-professed misanthrope due to past trauma. Hoping to live a slow, relaxing life, he takes a new teaching job in the mountains. But it turns out that this place is actually an all-girls school for demi-humans who want to become full-fledged human beings! (Source: Yen Press)
