The ongoing Welcome to Demon School! Iruma-kun Season 4 has gotten a second main trailer and main visual. The anime began airing on April 4 and will run for 24 episodes.
It was also announced that Yuma Uchida, Yoshitugu Matsuoka, and Misato Otsuoka are joining the cast as Leviathan Leiji, Belial-Berry Razberry, and Gyari, respectively.
The fourth season of the anime series comes four years after 2022’s third season, with the first two seasons debuting in 2019 and 2021. The anime is based on the manga by Osamu Nishi, with Kodansha USA describing the manga’s synopsis as such:
Hopeless pushover Iruma Suzuki has found himself in a devil of a predicament… His trashy parents have sold off his soul, and he now has to live and attend school in the Netherworld. But with his unique survival skills and doting demon grandfather’s support, Iruma will surely make it through this hellish experience. He’ll just need to subjugate rival classmates, summon familiars, and more, all while never revealing that he’s human… Easy as aleph, bet, gimel, right?
The Welcome to Demon School! Iruma-kun manga began serialization in 2017 in Akita Shoten’s Weekly Shonen Champion and has 49 volumes as of June 2026. The Welcome to Demon School! Iruma-kun: IruMafia Edition spin-off is set to receive an anime adaptation in 2027.
Crunchyroll and iQIYI are streaming Welcome to Demon School! Iruma-kun Season 4.
