The main visual for the fourth season of the TV anime "Welcome to Demon School! Iruma-kun," based on the manga by Nishi Osamu currently being serialized in "Weekly Shonen Champion" (Akita Shoten), has been released. In the fourth season, the protagonist, Suzuki Iruma, takes on a music festival that will test the unity of his class. The visual depicts the 13 members of his problem child (abnormal) class clad in glittering costumes and bathed in lights on stage. The fourth season will begin airing on NHK Educational TV in April 2026.
A teaser PV has also been released. The video features the impressive sound of a trumpet, and shows Iruma and his classmates remembering the existence of a long-forgotten 13th classmate, Purson Soi, as they must unite to win the music festival. Purson has always avoided contact with others, believing that he must "never stand out," so Iruma and his classmates desperately try to recruit him.
To commemorate the broadcast of the fourth season, it has also been announced that an event titled "Welcome to Demon School! Iruma-kun 4th Season WELCOME PARTY!!!!!!" will be held at Theater 1010 (Adachi Ward, Tokyo) on March 14, 2026. Voice actors Ayumu Murase(Iruma Suzuki), Kimura Ryohei (Asmodeus Alice), Asai Ayaka (Valac Clara), Daisuke Ono(Naberius Kalego), and Saiga Mitsuki (Opera) will be appearing, along with original author Nishi. Plans include a talk corner showcasing behind-the-scenes stories and various staff anecdotes, an original drama reading, and the release of new information.
