Welcome to Demon School! Iruma-kun is getting its first feature film. The anime’s “DEVIL’S PARTY! 2” event at Nippon Engineering College Arena in Tokyo on September 27 closed with a promotional video announcing a film project, and the video teases that the movie will tell a brand-new story rather than retell an arc fans have already seen.
The reveal landed at the end of a fan event that also looked ahead to the manga behind the series. The same video marked the upcoming 10th anniversary of Osamu Nishi’s original manga, which premiered in anime form in 2019 and has been running in print since March 2017.
What we know about the film
Beyond the announcement itself, details are still thin. There is no release date, release window, studio, staff list or confirmed format yet, and the teaser does not say whether the film will adapt manga material or tell a wholly original story. What the video does commit to is that the story is new, which points to original screenplay work rather than a straight adaptation of a single arc.
Ayumu Murase, who has voiced Iruma Suzuki since the first season, recorded a comment for the reveal. “I think it’s going to develop into something that makes you wonder, ‘What’s going to happen!?'” he said. “I’m really looking forward to it myself, and I hope everyone will come out to see it as well. For now, I’ll do my best with the recording, so please look forward to it!”
The 10th-anniversary note is a second, quieter piece of news. Nishi launched Mairimashita! Iruma-kun in Akita Shoten’s Weekly Shōnen Champion in March 2017, and the series has now reached 50 collected volumes as of September 8, 2026. A film arriving in the same period as that milestone is the kind of scheduling publishers and studios tend to plan around rather than stumble into.
What the series is
Welcome to Demon School! Iruma-kun follows Iruma, a kind-hearted 14-year-old whose parents sell him to demons for their own gain. The demon who buys him has no grandson of his own, so he dotes on Iruma instead and enrolls him at a demon school, where the human boy has to survive duels, rivals and classmates while his innate kindness slowly wins people over.
The anime so far
- Season 1: premiered October 2019 on NHK Educational with 23 episodes; Crunchyroll streamed it as it aired and added an English dub
- Season 2: premiered April 2021; Crunchyroll streamed it with an English dub following in June 2021
- Season 3: debuted October 2022 with a Crunchyroll simulcast
- Season 4: premiered April 4, 2026 on NHK Educational; ran for two cours and ended with its 24th episode on September 26, 2026
Crunchyroll streamed Season 4 across North America, Central America, South America, Europe, Africa, Oceania, the Middle East, the CIS and India, so the series’ audience is now genuinely global rather than limited to the Japanese broadcast footprint it started with on NHK Educational.
Why it matters
A first theatrical film is a step up in scale for any long-running TV anime, and for Iruma-kun it caps a run of steady growth: three TV seasons between 2019 and 2022, then a two-cours fourth season in 2026, and now a movie. Films also tend to carry bigger animation budgets and longer production schedules than a weekly series, which is one reason studios usually keep them for franchises with a proven audience.
The honest caveat is timing. Because nothing has been announced about when the film will arrive, the announcement is a promise rather than a plan readers can calendar yet. Given a film of this kind typically needs a year or more after an official reveal, fans should treat the reveal as the start of a wait, not the end of one.
It also helps that the source material is nowhere near finished. With 50 volumes in print and the manga still running in Weekly Shōnen Champion, the film has a deep well of unadapted chapters to draw from if it chooses to adapt rather than write something new.
