by The popular fantasy-comedy anime and manga series “Welcome to Demon School! Iruma-kun” is officially heading to the big screen for the first time. A theatrical film project for the franchise was announced during the special fan event “Devil’s Party 2” on September 27, 2026.
The announcement marks an important milestone for the series, which will celebrate the 10th anniversary of its manga serialization in 2027. Along with the announcement, a special promotional video was released, giving fans their first glimpse of the new theatrical project.
While details such as the movie’s release date, story, staff, and format have not yet been revealed, the announcement has already generated considerable excitement among fans. Voice actor Ayumu Murase, who plays the series’ protagonist Iruma Suzuki, also shared his enthusiasm, teasing that the project could develop in a way that makes viewers wonder, “What’s going to happen!?”
“Welcome to Demon School! Iruma-kun” Is Finally Coming to Theaters
“Welcome to Demon School! Iruma-kun” is a fantasy comedy series created by Osamu Nishi. The story follows Suzuki Iruma, a kind-hearted human boy who unexpectedly finds himself living in the demon world after his parents sell him to a powerful demon named Sullivan.
Rather than being harmed, Iruma is adopted by Sullivan and becomes his grandson. He is then enrolled at Babyls Demon School, where he must hide the fact that he is human.
The series combines school comedy, fantasy, action, friendship, and coming-of-age elements. Iruma gradually develops strong friendships with demons while becoming involved in increasingly unusual adventures at Babyls.
The manga began serialization in Akita Shoten’s “Weekly Shonen Champion” in March 2017 and has become one of the publisher’s major long-running titles. According to the announcement, the manga had surpassed 20 million copies in cumulative circulation as of March 2026.
The timing of the theatrical movie announcement is particularly notable because 2027 will mark 10 years since the manga began serialization.
The Announcement Came at “Devil’s Party 2”
The theatrical project was revealed during “Devil’s Party 2,” a special event held on September 27, 2026, at the Nippon Institute of Technology Arena.
The event brought together cast members, staff, the original manga creator Osamu Nishi, and fans of the franchise.
As the event approached its conclusion, a video suddenly appeared on the large screen. The words “Major Announcement” appeared first, followed by the announcement that a “Theatrical Film Project” had officially launched.
The unexpected reveal immediately drew cheers from the audience.
A special video connected to the theatrical project was also released following the announcement. However, the production team has not yet revealed important details such as the movie’s storyline, release schedule, theatrical distributor, or whether the film will feature an original story or adapt material from the manga.
This means fans will have to wait for future announcements to learn exactly what kind of adventure awaits Iruma and his friends on the big screen.
Ayumu Murase Shares His Excitement
Ayumu Murase, the voice actor behind Iruma Suzuki, reacted enthusiastically to the announcement.
Murase said that he believes the project will be “an amazing development” that will make fans wonder what is going to happen next. He also revealed that he is personally looking forward to the project and encouraged viewers to come and see the film when it is released.
He also joked that his immediate priority is to do his best during recording sessions and asked fans to look forward to the theatrical project.
For Murase, who has voiced Iruma throughout the anime series, the movie represents another major step for a character he has portrayed for years.
His comments also suggest that additional production information could be revealed gradually as the project moves forward.
Osamu Nishi Teases More Information
Original creator Osamu Nishi also appeared at the special event and commented on the theatrical announcement.
Nishi said that they were excited about the project but jokingly explained that people involved with the production had told them not to reveal too much.
Although the creator did not provide specific details about the film, Nishi encouraged fans to wait patiently and promised that the team was working hard on the project.
The limited information is likely to make the upcoming announcements particularly interesting for longtime readers and anime viewers who are eager to discover whether the movie will introduce a completely new storyline.
A Major Milestone Before the Manga’s 10th Anniversary
The theatrical announcement comes at an important moment in the history of “Welcome to Demon School! Iruma-kun.”
The manga began in 2017, meaning the franchise will reach its 10th anniversary in 2027. Over the years, the series has expanded from a manga into a major multimedia franchise with television anime seasons, music, events, merchandise, and a large international fanbase.
The anime adaptation premiered in October 2019. Since then, the story has continued to introduce new characters, magical abilities, school competitions, friendships, and increasingly important challenges for Iruma.
The theatrical movie could therefore become one of the biggest projects associated with the franchise’s 10th-anniversary period.
However, the exact relationship between the movie and the anniversary celebrations has not yet been officially explained.
Season 4 Recently Reached Its Conclusion
The announcement also follows the conclusion of the fourth season of the TV anime.
Season 4 began airing in April 2026 and concluded on September 26, 2026, giving fans a new reason to celebrate just before the theatrical project was revealed.
The fourth season continued Iruma’s adventures at Babyls Demon School and expanded the world surrounding the protagonist and his classmates.
With Season 4 now complete, attention naturally turns toward the franchise’s next major project.
The theatrical movie announcement provides fans with a new storyline to anticipate while the series moves toward its 10th anniversary.
What Could the Movie Be About?
At present, the production team has not revealed the film’s plot, so its story should not be assumed.
One possibility is that the movie could tell a completely original story created specifically for the theatrical format. Another possibility is that it could adapt or expand an important storyline from the manga.
The movie could also provide an opportunity to explore characters who have received less screen time in the television series.
Iruma’s relationships with Asmodeus Alice, Clara Valac, Ameri Azazel, Kalego Naberius, and the other students and teachers at Babyls have always been an important part of the series. A theatrical production could bring these characters together for a larger-scale adventure.
For now, however, the official information remains limited, and fans will need to wait for further announcements before drawing conclusions about the story.
Why the Theatrical Project Is Important for the Franchise
The move from television to the big screen represents another stage in the growth of “Welcome to Demon School! Iruma-kun.”
A theatrical release can offer a larger visual scale, more elaborate animation, and a self-contained story designed for a cinema audience. It can also introduce the franchise to viewers who may not have followed every television season.
For existing fans, meanwhile, the movie provides an opportunity to see Iruma, his classmates, and the demon world in a new format.
The announcement is also significant because it arrives after several successful years for the anime adaptation. Since the first season premiered in 2019, the series has steadily expanded its audience while maintaining its distinctive combination of comedy, fantasy, action, and emotional storytelling.
