Welcome to Demon School! Iruma-kun (Seasons 1–4)

Welcome to Demon School! Iruma-kun (2019) is a Japanese anime you can watch online on iFILM. Fourteen-year-old Iruma Suzuki is handed over to a demon by his careless parents.

It reads like a horror setup, then turns sweet. The demon who buys him, Sullivan, only wants a grandson, and he enrolls Iruma at Babyls, the Netherworld academy where he happens to be principal. Now the timid, eager-to-please boy has to hide that he's human among classmates who can smell an outsider from across the room — and somehow keep rising through the ranks of a school built for demons. A perfectionist honor student and a haughty heir from an old family end up at his side.

Adapted from Osamu Nishi's manga and running since 2019, it's a warm coming-of-age comedy wearing a monster-school costume, where Hell turns out kinder than the home that threw Iruma away. Easy to recommend for cozy fantasy with no cruelty or gore. Stream every season of Welcome to Demon School! Iruma-kun online on iFILM.
