Welcome to Demon School, Iruma-kun Season 4 Episode 8 puts the spotlight on growth—specifically, the kind that comes from admitting you've been stuck in the past. This week's installment features two demons reckoning with their own stubbornness, though in very different ways.

Poro and Soi's father (Mr. Purson) both have moments of reluctant acceptance, but theirs are fundamentally different reckonings. Poro's hung up on memories that may never have been what he remembers them to be. His relationship with the late Derkila was built around music, but time has warped those moments into justification for his rigid control over the music festival and the Misfit Class. He's been so committed to preserving what he thinks they shared that he's lost sight of what was actually real.

Mr. Purson, meanwhile, is trapped by expectations rather than nostalgia. He's spent years demanding that Soi be the perfect son—compliant, obedient, predictable. When Soi performs at the festival against his father's wishes, it's defiance. But when Soi tells his dad he won't follow that rigid mold, it becomes a declaration of independence. Soi isn't running away like his older brother did. He's claiming space to be both a leader and a musician, to write his own story on his own terms.

That parallel matters more than it might seem at first. The series has been building Asmodeus and Clara as Iruma's likely partners in his ascent to demon king, but this arc draws a line between healthy mentorship and control. Poro and Derkila's friendship, built on mutual creativity, contrasts sharply with Mr. Purson's one-way demands. One lifts you up; the other suffocates you.

Soi's victory isn't that he's won an argument with his father. It's that he's decided his future isn't his father's to dictate. Both Poro and Mr. Purson are learning—however painfully—that the next generation isn't going to live in the world they're stuck in. Sometimes growing up means watching the people who raised you finally catch up.
