Overview

Fourteen-year-old Iruma Suzuki has had the worst luck of any kid alive — until his irresponsible parents sell him to a demon. But instead of doom, Iruma gets the family he never had: the powerful demon Sullivan adopts him as his grandson and enrolls him at Babyls, the demon world’s most prestigious school, where Sullivan himself is chairman. The catch? Iruma is human, and if anyone finds out, he will be eaten. So the boy who could never say no must survive classes, exams and demon classmates — including the fiery Alice Asmodeus, the chaotic Clara Valac and the terrifying teacher Naberius Kalego — while climbing the demon ranks toward his dream of becoming Demon King. Across 89 episodes and four seasons, Welcome to Demon School! Iruma-kun is a warm, hilarious and surprisingly moving story about found family, courage and learning to want something for yourself.
