The following comment was provided on behalf of the group by member Natsu Minami, who is also a fan of the anime: We are thrilled to announce that CANDY TUNE will perform the ending theme for "Welcome to Demon School! Iruma-kun." I am deeply honored to be involved in this way as a fan who was so captivated by the series that I found myself wanting to join the Iruma Army. This track features CANDY TUNE's signature band sound, with its fast-paced melody and quick-speaking singing parts leaving a strong impression. Personally, I feel this overlaps with the chaotic atmosphere of the Misfit Class. I'm really looking forward to seeing what kind of ending emerges when it combines with Iruma-kun's worldview! Additionally, CANDY TUNE's official X (formerly Twitter) posted a video message from the members. Welcome to Demon School! Iruma-kun Season 4 Trailer Welcome to Demon School!
