Yen Press publishes the light novels in English and describes the story:
I'm Rei Hitoma, a self-professed misanthrope, thanks to some past trauma. Just when I thought my new teaching job in the mountains would provide a chill, rejuvenating environment, it turns out that this school is actually for demi-humans who want to become full-fledged human beings! There's a mermaid, a werewolf, a rabbit, and a bird...all of whom are now my charges. It's my duty to teach them about humankind—and maybe in the process, I'll learn a few things myself. This isn't an alternate world or a case of reincarnation. It's just the story of a teacher at a somewhat peculiar school, and his students who are striving to become human.
The light novels launched with its first volume with illustration by Sai Izumi in February 2022. Kadokawapublished the fourth volume in February 2025.
Atsu Benino's manga adaptation launched in Kadokawa's Shōnen Ace magazine in 2022. The manga ended on July 26, and the fourth and final volume shipped on September 26. Yen Press also publishes the manga in English.
