by The fourth season of the anime “Welcome to Demon School! Iruma-kun” will begin airing on NHK Educational TV in April 2026. To commemorate this, a one-day event will be held at Theater 1010 on March 14, 2026.
This one-day event, a must-see for fans, will feature voice actors Ayumu Murase (Iruma Suzuki), Ryohei Kimura (Asmodeus Alice), Sayaka Asai (Valac Clara), Daisuke Ono ( Naberius Kalego), Mitsuki Saiga (Opera), and other cast members, as well as a special appearance by the original author, Osamu Nishi. Plans include a talk corner introducing behind-the-scenes stories from the anime recording and various anecdotes from the production staff, the release of new information, and an original reading drama.
The main visual for the fourth series has also been released. The new event that the protagonist, Iruma Suzuki, is taking on is 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 illuminated on stage.
A teaser video featuring the trumpet’s striking sound has also been released. While the entire class must unite to win the music festival, Iruma and his friends suddenly remember their long-forgotten 13th classmate, Purson Soi. Purson, who has always avoided contact with others, believes in “never standing out.” How will he deal with Iruma and his friends’ desperate attempts to recruit him? Will all 13 of them be able to take the stage at the music festival and win? A musical reorganization, complete with difficulties, begins.
Based on the manga of the same name currently being serialized in Weekly Shonen Champion, the story follows Suzuki Iruma, a human boy who becomes the grandson of Sullivan, the great demon of the demon world, and enrolls at Babylls. In this school, Sullivan serves as chairman. It follows his struggles and growth at the demon school. The manga has sold over 19 million copies.
