Kodansha Comics publishes the original manga in English and it describes the story:
Monsters of legend walk among us, going by the name “demi-humans.” Ever since he’s discovered the “demis,” one young man has become obsessed with them. So when he gets a job as a teacher at a high school for demi-girls, it’s a dream come true! But these demis, who include a rambunctious vampire, a bashful headless girl, and a succubus, have all the problems normal teenagers have, on top of their supernatural conditions. How to handle a classroom full of them?!
The ongoing manga launched in the debut issue of Young Magazine the 3rd in September 2014, and Kodanshapublished the sixth volume in May.
The manga inspired a television anime in 2017. Crunchyroll streamed the series as it aired, and Funimationstreamed an English dub.
