Mairimashita Iruma-kun manga builds its entire comedy on the most dangerous secret a student has ever kept — a human boy enrolled in a demon school where the cafeteria would qualify him as a menu item, trying to stay invisible while the demon world keeps deciding he is interesting. You can read Mairimashita Iruma-kun manga online and follow Iruma Suzuki from the moment his parents sell his soul to a powerful demon who adopts him as a grandson, through every chaotic extracurricular disaster, bizarre school event, and accidental act of influence that turns the boy who just wanted to survive into one of the most talked-about figures in the Babyls demonic hierarchy.

Every chapter of Mairimashita Iruma-kun earns its warmth through the relationships Osamu Nishi builds around a protagonist whose defining trait is that he genuinely cannot stop caring about the demons who would theoretically eat him. Alice Asmodeus, Clara Valac, and Azazel Ameri are written with enough personality that the english translated chapters across 40 plus ongoing volumes feel like a genuine ensemble rather than a support cast, and the escalating demon-world power arcs give the school-life comedy real stakes without losing the tone that makes the series distinct. With a fourth anime season premiering in April 2026 bringing a new wave of readers to the source material, the manga goes significantly further than any season has reached.
