Welcome to Demon School! Iruma-kun Season 4 is airing in Spring 2026, with the Misfit Class's Music Festival arc underway. The series has held the top spot in Anime News Network's weekly reader poll and placed in the top five of Anime Corner's weekly rankings.
Welcome to Demon School! Iruma-kun Season 4 is in the middle of its Spring 2026 run. The season has performed well in reader polls: Anime News Network's weekly poll for episodes aired May 13-19 ranked Iruma-kun first, ahead of Witch Hat Atelier and Dorohedoro. In Anime Corner's Week 8 poll, the series placed fifth with a vote share that was not specified, while Re:ZERO Season 4 dominated that poll with 20.08%.
The season's Music Festival arc has been the focus of recent episodes. Episode 6, which aired on Mother's Day weekend, centers on Purson Soi's mother supporting his decision to defy his father and stay in the festival. The episode also introduces judge Poro, whose harsh judging style threatens the Misfit Class's performance without Purson. Episode 7 devotes its entire runtime to the Misfit Class's musical theater performance. The episode follows Keroli's choreography, which assigns each demon a role suited to their personality, and the class's collective faith that Purson Soi will appear despite being absent all day. Purson gradually fades into visibility during the performance, playing the mysterious bat demon Pixie, and the crowd reacts with enthusiasm. Iruma stays in the background during the episode, acting as a supportive presence rather than a lead performer. Kaede Hondo's singing as Elizabetta receives particular praise. The English dub lacks subtitles for the songs, which undermines the episode's immersive quality.
