TV-14Season 4
Synopsis
Watch Welcome to Demon School! Iruma-kun (2026), Season 4 online on iFILM — 12 episodes of comedy anime that put the Misfit Class on stage. To climb to Rank 4, all thirteen students have to pull off a performance at the Music Festival.
That number is the catch: it turns out the class has one more student than anyone realized — Purson, a quiet boy almost nobody can see. Iruma keeps trying to reach him while the class rehearses its act, the Hell Dance set to a song called "Lilith's Carpet," with stern Kalego unexpectedly stepping in as their coach. Once the festival wraps, the season eases off into shorter slice-of-life chapters: Iruma and Asmodeus spending a day together, Lead's family drama, the usual chaos of the trio.
At twelve episodes it's a shorter run than the earlier seasons, so the focus is on character rather than scale — a new classmate and a stage arc give some of the background cast room to step forward. A fine entry point for anyone who's followed the show from the start. Stream Welcome to Demon School! Iruma-kun Season 4 online on iFILM.
