Iruma-kun IruMafia Anime Sets January Debut

The demon school crowd is trading classrooms for a crime family. Welcome to Demon School! Iruma-kun: IruMafia Edition will premiere on January 4, 2027, at 11:00 p.m. on NHK General TV in Japan, according to Anime News Network, with a 12-episode run planned. The Iruma-kun IruMafia anime brings the spinoff manga to television. The announcement arrived with a main visual and a set of character visuals for the spinoff, giving fans a first look at familiar faces recast in a mafia underworld.

IruMafia Edition is an alternate-universe take on the franchise, separate from the main story. In this version, Iruma is a poor but kind boy growing up in a rough city slum, and a small act of generosity changes his life. He shares his last loaf of bread with a severely injured old man and nurses the stranger back to health, only to learn the man is Don Sullivan, leader of the Babel Mafia. Sullivan takes Iruma in and asks the boy to become his grandson, which puts the kindhearted teenager in line to inherit a sprawling demonic crime family. The setup keeps the core joke of the original series intact while swapping school corridors for backroom deals and family loyalty. It is a simple swap with a lot of room for trouble, since Iruma survives by being decent in places that reward the opposite.

Returning voices lead the cast

The cast list leans on familiarity. Ayumu Murase returns as Iruma, with Ryohei Kimura as Alice Asmodeus, Ayaka Asai as Clara Valac, Mitsuki Saiga as Opera, Saori Hayami as Ameri, and Daisuke Ono as Kalego Naberius, Crunchyroll News reported. Each actor voices the same character they play in the main series, but the alternate setting gives those relationships a different edge. Keiichiro Kawaguchi directs the series for Tatsunoko Production, with Kazuyuki Fudeyasu handling series composition, Kenji Fujisaki designing the characters, and Yayoi Sekimukai composing the music. The staff list reads like a reunion too, which suits a spinoff built on characters the audience already knows.

A spinoff with its own manga history

The anime adapts a spinoff manga drawn by hiroja, based on Osamu Nishi's original series. The manga began in Bessatsu Shonen Champion in September 2023 and later moved to Weekly Shonen Champion, where it now runs on a biweekly schedule. The main Welcome to Demon School! Iruma-kun manga has reached 50 volumes, and its anime adaptation premiered in 2019 and streams on Crunchyroll. A fourth season of the main series began airing in April of this year, and a separate theatrical film project is also in development.

The newly revealed main visual puts the cast in sharp suits against a city backdrop, a deliberate break from the school uniforms and demon academy halls of the main show. Character visuals for the central cast arrived alongside it, letting viewers compare each familiar face with their mafia counterpart. The look sets the tone for the whole project: the same characters and humor, in a world where manners and menace sit side by side.

What remains unanswered is how viewers outside Japan will watch it. No international streaming platform has been announced yet, according to reports on the announcement, so fans abroad will have to wait for licensing news. The manga itself is already reaching English readers through Kodansha USA, which gives newcomers a way into the mafia twist before the broadcast begins. That gap between the Japanese premiere and any overseas release is common for NHK-aired anime, and it often closes once a streaming partner picks up the show. Kodansha USA's English edition of the spinoff manga gives readers outside Japan a way to meet this version of Iruma before the anime airs.

For longtime viewers, the appeal is the reunion as much as the premise. The main series built its audience on a human boy surviving demon school through kindness and quick thinking, and the spinoff tests whether that same charm works when the stakes are set by a crime family instead of a classroom. Fans will get their answer when the show opens on NHK, with the main visual already setting the tone for a darker and more tailored take on the demon world. The Iruma-kun IruMafia anime will show whether a demon school favorite can carry a crime story on charm alone.
