What Happened in Episode 15?
Episode 15, which aired on July 11, 2026, focused on character development and lighter moments. The episode began with a reminder of Iruma Suzuki’s goal to keep advancing at Babyls Academy.
A major part of the episode centered on Jazz, a member of the Misfit Class. Jazz was training his familiar, a wolf-like creature named Spoo. He hoped that after his recent promotion, Spoo would become stronger. However, Spoo remained playful and awkward, spending more time dancing than fighting. Iruma accidentally discovered Jazz’s secret training. Jazz then admitted that he was worried because a familiar reflects its owner’s character, and Spoo’s behavior suggested that Jazz himself was “too cute”. Iruma reassured Jazz that he should not be troubled, as Spoo was already strong and had a warm nature like Jazz.
The episode then shifted to Lied, who was contacted by Azz about playing video games. Lied thought it would be a serious competition, but it turned out to be a practice match because Azz wanted to play the game with Iruma when it came out. After their matches, Azz opened up about his past, which was filled with expectations and loneliness. Lied told him to enjoy the small fun things they could do together. Following this advice, Azz invited Iruma and Clara to spend some fun time together.
What to Expect in Episode 16
Episode 16 is expected to continue the series’ blend of comedy and character growth. The show will likely begin preparing for the bonenkai, which is the Demon World New Year’s party. This event usually involves many characters and leads to funny situations. It also provides opportunities for character development outside the main plot.
The episode might also revisit unresolved storylines from previous episodes. For example, viewers might see more of Jazz bonding with his familiar Spoo, or how Azz is adjusting to his new life at school. Festival episodes in Iruma-kun often introduce new demon cultures, giving Iruma more chances to learn about the demon world.

Season 4 of Welcome to Demon School! Iruma-kun centers on the Music Festival arc. The Misfit Class faces a major challenge: all 13 members must reach Rank 4.
