Welcome to Demon School! Iruma-kun is officially returning with Season 4 in April 2026, with the window confirmed on NHK’s official page.

TL;DR
Iruma-kun is back in April 2026. The exact day is not confirmed yet, but the Season 4 window is locked.

Key Details
• NHK’s official Iruma-kun page lists Season 4 as broadcasting starting April 2026.
• Crunchyroll has published Season 4 promotional updates, including a trailer and visual.
• Crunchyroll also shared additional cast news, including Purson Soi.
• A specific date in April 2026 has not been confirmed in the official pages cited.

Breakdown
This is the kind of announcement fans want most: an actual season window from an official broadcaster source. April 2026 also lines up with a big Spring slate, which usually means strong weekly conversation and lots of shared reactions.

Crunchyroll’s steady promo drip suggests Season 4 will not be a quiet drop. Between a trailer, visuals, and cast updates, this looks like a planned push into the next arc, not just a routine return.

With no exact day yet, the main practical move is simple. Treat it as Spring 2026 and wait for the specific premiere date as we get closer to April.

What to Watch Next
• The exact April premiere day and time slot
• More cast announcements and character visuals
• Whether Crunchyroll confirms same day streaming timing
• Any hints about which manga arc Season 4 will emphasize first
