English Season Dub Review: Welcome to Demon School! Iruma-kun Season 4
Welcome to Demon School! Iruma-kun returns with a much stronger and more confident start, shifting into the Music Festival arc, which feels far better suited to the anime’s pacing and tone compared to the previous season. The premiere reintroduces the lively charm of the Misfit Class while placing a welcome spotlight on Soi Purson, a previously overlooked classmate whose ability to blend into the background is cleverly explained through his family lineage and personal struggles with standing out. Despite his reserved nature, Purson proves to be surprisingly expressive when given the chance, revealing both a relatable personality and a hidden music talent that naturally ties into the upcoming challenge, while Iruma’s encouragement, equal parts genuine kindness and determined ambition, pushes him to step forward in a way that feels true to the series’ themes.
On the technical side, Season Four continues the series’ established production team, with Makoto Moriwaki returning as chief director and Ayaka Tsujihashi taking over as director at Bandai Namco Pictures, alongside Kazuyuki Fudeyasu handling series composition, Yumiko Hara on character designs, and Akimitsu Honma composing the music. The opening theme is “Ichi Ni no San” (“One, Two and Three”), performed by Penthouse, while the ending theme is “Super Yusho Tune!” performed by CANDY TUNE, marking the latest musical additions to the series’ ongoing run.
Welcome to Demon School Iruma Kun returns with the same infectious charm that has made it such a comforting series to revisit. Rather than focusing solely on Iruma’s growth, the story gives more attention to the Misfit Class and the relationships they continue to build. Its slice-of-life foundation remains intact, blending comedy, character interactions, and gradual world-building. While the slower pace may not appeal to everyone, it allows the supporting cast to receive more attention without taking away from Iruma himself.
The strongest material comes during the Music Festival, particularly the Lilith’s Carpet arc. What begins as another school event develops into a fun character-driven story that allows several members of the Misfit Class to shine. The preparation is filled with entertaining interactions, while the eventual performance brings together the season’s strongest character moments. The newly introduced “Soi Purson”, in particular, benefits from the additional focus, making this one of the most memorable portions of the series without needing to rely on major plot developments.
The Dem-Dol Games arc, which happens much later on, provides another entertaining change of pace, bringing plenty of comedy and chaotic energy along with it, and adds another layer of fun, while the dynamic between the two rival Dem-Dols provides an unexpectedly engaging subplot. That said, the pacing can become somewhat uneven, especially during the more relaxed episodes, since much of it was callbacks to a Season One episode where Iruma was forced to Crossdress to help a friend out.
In terms of sounds and visuals, the series continues to capture its colorful and energetic personality. The Music Festival is particularly impressive, with its choreography, animation, and musical performances coming together beautifully. The songs and vocal performances add plenty of personality, while the voice acting remains one of the show’s biggest strengths. Even the occasional imperfections help preserve the charm of watching the characters put together a school production rather than something overly polished.
Overall, Season 4 was an enjoyable continuation that puts the Misfit Class more firmly in the spotlight. Its slower, more character-focused approach may not satisfy viewers looking for major plot progression, but there is still plenty to appreciate in its humor, heart, and character development. Most importantly, it continues to show just how much these characters have grown together, and sometimes, watching a group of misfits simply enjoy being themselves is exactly what makes the series so much fun.
