Welcome to Demon School! Iruma-kun Season 4 Reveals Main Trailer

A main trailer for Welcome to Demon School! Iruma-kun‘s fourth season has been unveiled, along with Takehito Koyasu‘s casting as Amduscias Polo.

Earlier this month, it was announced that the anime would start its broadcast on April 4 (JST), and that it will have a two-cour length.

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?

Welcome to Demon School! Iruma-kun’s earlier seasons in 2019, 2021, and 2022. An anime adaptation of the Welcome to Demon School! Iruma-kun: IruMafia Editionspin-off will air in 2027.
