The watch order
There's no spin-off maze here — watch it straight through in release order:
- Season 1 (2019) — Iruma enrolls, meets Alice and Clara, and sets his impossible goal: survive Babyls without anyone learning he's human.
- Season 2 (2021) — the Battler arc and the school festival raise the stakes and the cast.
- Season 3 (2022) — the Harvest Festival and Iruma's bloodline start paying off.
- Season 4 (2026) — airing now, picking up the momentum of the third.
Skip nothing; there are no recap films you need for continuity.
Where to watch
All four seasons stream on Crunchyroll. We'll say it plainly rather than nudge you toward one storefront: for now, Iruma-kun is a Crunchyroll title, subtitled with a dub catalog behind it. The show originally aired on NHK Educational in Japan, which is part of why it stays so briskly family-friendly.
Is it good?
Short version: yes, if you want warmth over edge. Iruma-kun is a shonen comedy that rarely reaches for shock — its engine is a likable underdog surrounded by an escalating cast of weirdos. Per SenpaiRanks's ranking, it holds a comfortable spot in the mid-to-upper tier of the comedy board; the dual-axis read shows a show that's broadly liked and consistent season to season rather than a spiky one-cour standout. If you've burned out on grim isekai, this is the palate cleanser.
