Overview
Mairimashita! Iruma-kun 4 (Welcome to Demon School! Iruma-kun Season 4) adapts Osamu Nishi's manga, is produced by Bandai Namco Pictures, runs 24 episodes and began airing on 4/4/2026. According to the synopsis, Suzuki Iruma and all thirteen students of the Misfit Class must perform to reach Rank 4 at the Music Festival.
OtaHub's take
The series combines comedy, fantasy and the supernatural, placing a human boy in a school for demons. Makoto Moriwaki is chief director, Ayaka Tsujihashi directs and Kazuyuki Fudeyasu handles series composition. It follows directly on from Mairimashita! Iruma-kun 3, so the character relationships are already established.
Verdict
It suits viewers who like warm fantasy comedy and a colourful supporting cast, but newcomers should begin with the first season rather than jump into season 4.
