Welcome to Demon School! Iruma-kun Season 4 Reveals April 4 Start, 2 Cours Length

By /

Welcome to Demon School! Iruma-kun Season 4 is set to begin airing on April 4. 

It was also announced that the TV anime will have two cours, and that “Ichininosan” by Penthouse is the opening theme song.

Welcome to Demon School! Iruma-kun is based on Osamu Nishi’s manga, which began in 2017 in Akita Shoten’s Weekly Shonen Champion and has 46 volumes as of February 2026. Kodansha USA describes the manga 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 previous seasons of the anime premiered in 2019, 2021, and 2022. 2027 will see the debut of the Welcome to Demon School! Iruma-kun: IruMafia Edition spin-off’s own anime adaptation.

Crunchyroll has secured Welcome to Demon School! Iruma-kun Season 4 for streaming.
