Iruma-kun Season 4 – Welcome to Demon School!

Iruma-kun (Mairimashita! Iruma-kun) is officially coming back for Season 4, and we finally have a premiere window. The series, which has steadily grown into a favorite among anime fans looking for lighthearted fun mixed with surprising emotional depth, is set to return in April 2026. With Crunchyroll confirming it will stream the new season internationally, fans around the globe can look forward to diving back into Iruma’s hilarious and heartwarming school life.

The big reveal happened during a Welcome to Demon School! special event in 2024, where the production committee announced the continuation of the anime. Shortly after, anime news outlets confirmed the return for April 2026, with Crunchyroll on board for streaming. While no detailed trailers or key visuals have dropped yet, the announcement alone sent the fanbase into celebratory chaos. But right now, the release window is locked to April 2026 but the production team has yet to release an official trailer, staff details, or returning cast list. Given how the previous three seasons were handled, it’s safe to assume that Iruma (Ayumu Murase), Alice, Clara, and the rest of Babyls Academy’s beloved characters will be back with their original voices.

The lack of full production details isn’t unusual. Anime announcements often secure the TV slot first, and then marketing slowly ramps up closer to release with promotional videos, visual art, and key cast/staff confirmations. So, expect to see a steady drip of updates throughout 2025.

Without giving away heavy manga spoilers, Season 4 is expected to pick up where Season 3 left off, diving into some of the manga’s more exciting school arcs. Fans are buzzing about the potential for new festival events, training arcs, and the ongoing development of Iruma as both a student and an accidental rising star in the Netherworld. If Season 4 follows the adaptation pace of previous seasons, viewers can expect around 20+ episodes covering multiple story arcs. That means more spotlight on fan-favorite characters like Ameri, Opera, and even the eccentric Headmaster Sullivan.

Therefore, season 4 of Welcome to Demon School! Iruma-kun is shaping up to be another fun-filled ride through Babyls Academy. While details are still under wraps, the April 2026 premiere gives fans something solid to look forward to.
