What's Still Ahead in Season 4
According to the official account, Season 4 is far from over. Several major story events are still on the horizon, promising a packed second half for the season.

New Cast Members
Three new voice actors have been confirmed for Season 4, each bringing notable names to the project. Two of the newly introduced characters — Leviathan Leiji and Belial-Berry Raspberry — are members of the so-called "Three Greats" generation, meaning they are grandsons of the immensely powerful Three Greats demons. Along with Iruma, they are considered potential candidates for the future Demon King throne, making their introduction a pivotal development in the series' overarching story.
All three characters appear in the new main PV trailer, giving viewers their first impression of how these additions will fit into Season 4's evolving story.
About the Series
Welcome to Demon School! Iruma-kun is based on the manga by Osamu Nishi, serialized in Weekly Shonen Champion. As of June 2025, the series spans 22 volumes. The anime first premiered in 2019 and has been going strong ever since, finding a dedicated global audience through Crunchyroll's streaming platform.
Fourteen-year-old Suzuki Iruma is an ordinary human boy who unexpectedly finds himself whisked away into the demon world. To make things stranger, the demon who brought him there — Sullivan — appoints himself as Iruma's doting grandfather and enrolls him in the prestigious demon school. Navigating duels, classmates with unique quirks, and the constant fear of being exposed as a human, Iruma's natural kindness slowly but surely begins to win over even the most fearsome demons around him.
