Welcome to Demon School! Iruma-kun Watch Order

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.
