The highly anticipated fourth season of Welcome to Demon School! Iruma-kun (Mairimashita! Iruma-kun) is officially preparing for its return. Fans were recently treated to the release of a stunning new key visual, an exciting teaser promotional video, and confirmation regarding key production staff additions. Continuing the adaptation of Osamu Nishi’s beloved comedy-fantasy manga, the series is scheduled to debut on NHK Educational TV in Japan in April 2026. The upcoming installment promises to deepen the saga of Iruma Suzuki, the kind-hearted 14-year-old human who finds himself navigating the chaotic, often hilarious, world of a demon school after being unknowingly sold into service.

Production Staff and Studio Consistency

This new chapter introduces fresh talent to the production team while maintaining core creative consistency. Ayaka Tsujihashi, recognized for her directorial work on titles like Tsuki ga Michibiku Isekai Douchuu, steps up as the new director. Joining her is Saaya Sawada, who transitions from assistant production management on Birdie Wing: Golf Girls' Story to take on the crucial role of animation producer. Ensuring the show retains its established tone and quality, veterans Makoto Moriwaki returns as chief director, Kazuyuki Fudeyasu handles series composition, and Yumiko Hara is back to design the vibrant characters. Animation powerhouse Bandai Namco Pictures will once again be at the helm of production, upholding the visual standards set since the series’ premiere.

The Music Festival Arc Confirmed

The recently dropped teaser trailer offered a tantalizing glimpse into the next major storyline, officially confirming the adaptation of the fan-favorite Music Festival Arc. Critically, the preview introduced Purson Soi, the long-absent 13th member of the Abnormal Class, setting the stage for significant group dynamics and character exploration. This pivotal arc sees the first-year classes engage in a high-stakes performance contest, scrutinized by potential industry scouts. This scenario is ripe with opportunities for humor, drama, and extraordinary magical performances.

International Distribution and Manga Success

International viewers can rejoice as streaming giant Crunchyroll has successfully secured the rights for broad distribution across numerous territories, including North and South America, Europe, Africa, Oceania, the Middle East, the CIS, and India. Enthusiasts will not have to wait until 2026 to catch the action; Crunchyroll plans an exclusive early screening of the season's premiere at the Anime Frontier event in December 2025. With Osamu Nishi’s original manga continuing its run since 2017, and the 46th volume set for release in December 2025, the persistent success and renewal of the anime underscore the enduring appeal of this supernatural school comedy. High anticipation surrounds this installment, which is poised to deliver more laughter, challenges, and heartwarming demon school moments.
