Synopsis: Iruma Suzuki, 14, has never had the best life. Forced to work odd jobs since his early youth, he finds that his parents have done something beyond the pale: they've sold his soul to a demon named Sullivan. Sullivan's goal? To make the young Iruma, a human (considered a delicacy in the Netherworld), his... beloved, doted-upon grandson! Iruma is enrolled in a demon school, and warned that if the other demons ever find out what he is, they'll eat him.
Anime adaptation has finished airing its first season, and the second is coming next year.
