Welcome to Demon School! Iruma-kun gets a theatrical film

The Iruma-kun anime is getting a theatrical film. The official website for Welcome to Demon School! Iruma-kun posted on 27 September that a film project has started, alongside a special video and a promise that further details will follow.

That is the whole announcement, and it is worth being precise about how little is in it. There is no release date, no subtitle, no cast addition and no studio credit on the post, which says only that the theatrical project has launched, that a special video has been released and that viewers should wait for more news. The announcement visual is a title treatment with no character art, which suggests the production is being announced before it is being shown.

What the series brings to a film

The anime adapts Osamu Nishi's manga, which has run in Akita Shoten's Weekly Shōnen Champion since March 2017 and has passed 20 million copies in circulation across the series. The television version has been running since 2019, and the fourth season began in April 2026 as a two-cour run of 24 episodes on NHK, following Iruma Suzuki as a human boy passing himself off as a demon at the Babyls Demon School.

A film is the natural next step for a show that has spent four television seasons building a large ensemble around a school setting. The manga's later arcs move further into demon-world politics and the thirteen-crown gatherings, material that needs more room than a weekly slot comfortably gives it, which is usually the argument for a theatrical release in the first place.

Why the timing makes sense

Announcing a project with nothing attached is a familiar rhythm for Japanese animation, where a theatrical green light is often used to keep a franchise visible between television seasons rather than to launch something finished. The series has been a reliable performer rather than a breakout hit, and a film lets the production committee test a bigger budget against the audience the four seasons have built without committing to a fifth season straight away.

Our opinion

There is a version of this announcement that is genuinely exciting and a version that is a placeholder, and the official post gives away nothing about which one this is. The detail worth caring about is that the manga has moved past the school comedy into conspiracies that would look superb on a cinema screen, and a film is a chance to let the animation breathe instead of rationing movement across twenty-four episodes. The caution is that anime films spun off from long-running series have a habit of turning into extended episodes with a bigger budget and a returning villain. What would settle it is a studio and a director credit, not a date. Until those appear, the honest reading is that a film exists on a planning document and the special video is the only thing worth watching.
