Iruma Suzuki’s parents were horrible, nasty people who didn’t just mistreat him, they literally sold his soul to a demon! Ironically, however, it turns out surprisingly well, as it seems that the Demon has always wanted a grandson and is determined to make Iruma fit into that role… even if that means that Iruma has to go to school with all the other demon kids. Since Iruma’s never had a decent education, he’s fine with that, but there’s a catch: if anyone learns that he’s human, his classmates will eat him! Talk about pressure to fit in! Amazingly, Iruma manages to blend in fairly well with his devilishly good new friends! Now, if he could only stop nearly giving himself away by trying to do nice things, he might even survive to graduate in WELCOME TO DEMON SCHOOL, IRUMA-KUN!
