Welcome to Demon School! Iruma-kun Watch Order
5 entries · · community-maintained
The Welcome to Demon School! Iruma-kun watch order runs four seasons and 89 episodes in release order, plus the upcoming If Episode of Mafia spin-off, with no OVAs or movies to fit in. Start with the 2019 first season, 23 episodes that cover Iruma being adopted by the demon Sullivan and enrolling at Babyls. Season 2 and Season 3, 21 episodes each, continue straight on from one another, and Season 4, airing from April 2026 with 24 episodes, picks up directly after Season 3. Because every season is a direct continuation, the correct order is simply the release order, and there are no specials or recap films to work out along the way. If Episode of Mafia, arriving in January 2027, adapts the alternate-universe spin-off manga that recasts the same characters as a mafia family. It is placed last as optional viewing since it is not part of the main story. If you are wondering where to start, it is Season 1, episode 1.

How this order works
AnimeChrono watch orders put every season, movie, OVA, ONA and special for a franchise in chronological story order, the order the events happen. When an OVA or movie takes place partway through a season, the episode range is split so it sits where it belongs. Entries you can skip are marked optional, and each order says where to start. Release order, sorted by air date, is a secondary view once every entry has a date. The orders began as a hand-curated set, and episode counts and air dates come from AniList. Fans maintain the orders from there. Any signed-in user can edit one. Edits from trusted contributors go live right away and the rest are reviewed first. Every change is versioned and can be reverted, and each order shows when it was last updated and last checked.
