Synopsis

*Welcome to Demon School! Iruma-kun Season 4* continues the story of Iruma Suzuki as he navigates daily life and lessons at the demon world’s Babyls School. With his human identity still a secret, Iruma keeps adapting to the school’s eccentric rules, classmates, and magical mishaps.

The fourth season returns to the same mix of fantasy school antics and warmhearted comedy, following Iruma’s ongoing growth among demons who are anything but ordinary.

Otaku Consensus

Season 4 is being received as one of anime’s more reliable comfort-comedy sequels: Makoto Moriwaki and Ayaka Tsujihashi keep the school chaos buoyant, while Bandai Namco Pictures’ bright, elastic staging supports the series’ mix of slapstick and sincerity. The music-forward flavor is a real asset, with fans calling out the opening as another “absolute bop” and the ending as upbeat fun, matching AniList’s unusually prominent Musical Theater and Band tags. The clearest recurring complaint is localization, especially viewer frustration that songs and Japanese on-screen text have not consistently received English covers or subtitles.

Why You Should Watch

Pick this up if you want a school shounen that treats kindness, performance, and classroom chaos as seriously as tournament brackets. Season 4 scratches the same itch as My Hero Academia’s class dynamics and Little Witch Academia’s magical-campus whimsy, but with far less angst and a stronger sitcom rhythm. Bandai Namco Pictures leans into elastic reaction comedy, while Akimitsu Honma’s music matters more than background flavor thanks to the season’s musical-theater and band emphasis. The appeal is the trio chemistry: Iruma’s survival-by-empathy energy, Alice’s dramatic loyalty, and Clara’s gremlin creativity keep the ensemble from becoming lore homework. If you want fantasy school comedy with songs, demon aesthetics, and found-family warmth without grimdark stakes or isekai power-fantasy swagger, this is the comfort-food version with actual craft behind it.

Key Characters

I
Iruma Suzuki(VA: Ayumu Murase)
Iruma works because he is a soft-spoken moral center in a loud ensemble, turning de-escalation, politeness, and adaptability into comic strengths.
A
Alice Asmodeus(VA: Ryouhei Kimura)
Alice is the polished, high-intensity counterpart to Iruma, beloved for making loyalty feel both absurdly theatrical and completely sincere.
C
Clara Valac(VA: Ayaka Asai)
Clara is the show’s chaos engine, but her appeal comes from how her surreal playfulness creates chemistry rather than just noise.

What Makes It Stand Out

1
Bandai Namco Pictures produces the season, and the studio’s approach fits a comedy where exaggerated reaction cuts, colorful designs, and quick shifts in tone are central to the humor.
2
The staff structure pairs chief director Makoto Moriwaki with director Ayaka Tsujihashi, while Kazuyuki Fudeyasu handles series composition; that combination gives the 24-episode cour a steady comedic rhythm instead of feeling like disconnected gags.
3
Music is unusually central to the season’s identity: AniList tags it with Musical Theater at 66% and Band at 65%, and early viewer impressions singled out the opening as part of the franchise’s “absolute bops” streak.
4
Akimitsu Honma is credited for music and Hozumi Gouda as sound director, a notable pairing for a season where songs, performance energy, and timing-heavy comedy are not just decorative extras.
5
Its reception is strong but still niche: MAL lists an 8.12 score from 9,835 votes and a #564 rank, while its #2721 popularity suggests a sequel audience that is smaller than its approval rating would imply.

Fun Facts & Trivia

Fun fact 1: Season 4 began airing on April 4, 2026 and is listed for 24 episodes, keeping it in the longer two-cour range rather than the more common 12-episode sequel format.
Fun fact 2: Osamu Nishi is credited as the original creator, with Yumiko Hara on character design, Hitomi Yoshida as art director, Tomoe Takaya on color design, and Hiroyuki Chiba as director of photography.
Fun fact 3: AniList’s tag spread is unusually specific for a fantasy comedy: School is marked at 88%, Demons at 85%, Magic and Isekai at 80%, and Found Family at 53%.
Fun fact 4: The season holds an AniList score of 80/100 with 779 favourites, closely tracking MAL’s 8.12/10 audience score rather than showing a major platform split.
Fun fact 5: One localization issue has become a talking point among English-language viewers: since Season 3, some fans have criticized the lack of English song covers and missing subtitles for songs or Japanese text on screen.
