Mairimashita! Iruma-kun 4th Season

Iruma and the rest of the Misfit Class face a new challenge at the Music Festival, where all 13 students must prove themselves worthy of reaching Rank 4. After learning to fight, cultivate their talents, and cooperate in countless ways, they now confront a test that raw power cannot solve: creating one performance that gives every member a place to shine.

For Iruma, still hiding the fact that he is human in the demon world, the stage becomes another place to learn how to stand beside his friends instead of disappearing into the background. Between rehearsals, rivalries, and the usual Babyls chaos, the class discovers that true harmony is harder than individual excellence, but may be the only way for all of them to rise together.
