The opening stretch of Welcome to Demon School, Iruma-kun Season 4 does something fans have been waiting on for ages: it finally gives Soi Purson a proper spotlight.
If you've been watching the series closely, Purson has basically been the ultimate background guy for three whole seasons. Episodes 1 to 3 turn that running joke into the main emotional hook, and honestly, it works. Instead of treating him like just a punchline, the season starts digging into why he keeps himself hidden and why being noticed feels like a problem, not a win.
Purson's whole deal is especially easy to understand. He's quiet, reserved, and clearly more comfortable staying out of everyone's way. On top of that, his family's bloodline ability is built around going unnoticed, so disappearing into the background is not just habit, it's pressure from home too. The show even reveals that his older brother is so good at staying hidden that Purson has never even properly seen him. That's funny in that weird Iruma-kun way, but it also makes Purson's situation feel kind of heavy.
That becomes a big issue because the Misfit Class needs him involved. Their classroom status depends on rank progress, and suddenly Purson is being pushed toward centre stage when that's the exact opposite of what he wants. He even calls out Iruma and the others for being selfish, which is fair. They're asking him to step up because it helps everyone else.
What makes the setup stronger is that Purson isn't just refusing for no reason. He genuinely loves music. That's the place where he can express himself, even if speaking openly to people is hard for him. So the conflict in these episodes isn't simply "shy boy must perform." It's more about whether Iruma can help someone join in without forcing them to become a completely different person.
That tension feeds straight into the Music Festival setup, which looks like the big early arc for the season. For a series that usually balances chaos, comedy, and wholesome friendship, this is a smart angle. Purson's problem feels personal, and Iruma has to handle it carefully instead of fixing everything with pure kindness and vibes.
Episode 2 goes a bit sideways from that main plot, pairing up Naphula and Ronove in a combo that is, frankly, chaos. Ronove being loud, sparkly, and impossible to ignore makes him the exact kind of person who would give Purson a headache. Ameri sends him out with Naphula to check on the first years, and that side story also ties back neatly to the broader character work. It even throws in another look at the in-universe shoujo manga First Love Memories, which remains one of the funniest recurring bits in the franchise.
The other big win in these episodes is how much new character detail gets sprinkled around. Purson turns out to be much more talkative when he's comfortable, and he has a sneaky sense of humour too. Sabnock and Kalego being skilled pianists is the kind of random reveal this series loves, while Keroli gets to lean back into her secret dem-dol side. Her performance choice, plus Elizabetta's succubus angle and Asmodeus reacting exactly how you'd expect, gives the whole class dynamic more energy heading into the festival.
For Malaysian and SEA anime fans, this is the kind of season opener that's easy to vibe with. School performance arcs always hit when the cast chemistry is strong, and Purson's introvert struggle is super relatable if you've ever been the quiet one in a loud group project. It also helps that Iruma-kun is still streaming on Crunchyroll, so regional fans can keep up without too much hassle.
If Season 4 keeps this balance of comedy, awkward feelings, and character growth, the Music Festival arc could end up being one of the more memorable Iruma-kun stretches in a while.
