Welcome to Demon School! Iruma-kun Season 4 is mid-run on Crunchyroll, and Episode 12 just pulled a 4.4/5 community score — proof the demon-world comedy hasn't lost a step four seasons deep. If you've fallen behind, here's the where-to-watch and how it stacks up.
Quick answer
Welcome to Demon School! Iruma-kun Season 4 is currently airing on Crunchyroll (sub and dub), continuing the story of Iruma Suzuki, a human boy raised by a demon in the Netherworld school of Babyls. According to SenpaiRanks, the franchise ranks in the upper tier of the comedy board on the Consensus axis — its defining strength is broad, durable likability, with episodes like this one balancing old-school antics against world-changing stakes. It's one of the safest comedy picks airing right now.
What you're getting into
The pitch hasn't changed since Season 1: a relentlessly likable human survives demon school by being too earnest to fail. What keeps Season 4 fresh is the escalation — Ameri's arc as student council president pushes the show past gag territory into actual character development, the kind of slow build a four-season run earns.
Where to watch it
Crunchyroll carries all four seasons, so a newcomer can run the whole franchise in order without platform-hopping — a cleaner path than chasing it across services. That continuity is part of why it's an easy recommend.
How the franchise ranks
SenpaiRanks tracks Iruma-kun in the upper tier of its comedy ranking, with earlier seasons posting strong Consensus scores — this is a show people keep liking, season over season, which is exactly what the Consensus axis is built to surface. Quality holds steady rather than spiking; it's comfort-watch excellence, not a prestige swing. Slot it next to other current crowd-pleasers like Red Cat Ramen on the what to watch this season hub, or the action-leaning Blue Lock if you want a tonal change-up. Think it's underrated? Add your score on its ranking page — that's how the board stays honest.
