The Misfit Class’ music festival arc just got more personal
Welcome to Demon School, Iruma-kun Season 4 episode 5 pushes the music festival beyond a simple school competition. Yes, the Misfit Class still needs a strong performance if they want to keep Royal One, their ridiculously premium classroom. But this episode makes it clear that the bigger story is Soi Purson finally stepping out from the background.
For Malaysian and SEA anime fans following weekly school-life shonen series, this is the kind of episode that reminds you why Iruma-kun has stayed so beloved. It is goofy, colourful, and very anime in the best way — but underneath the comedy, the show is dealing with something pretty relatable: the pressure of family expectations, wanting to belong, and trying to be seen as your own person.
Poro may be a problem for the Misfit Class
Episode 5 also raises a new concern around Poro, one of the judges for the music festival. The issue is not just that he has a big personality. The bigger problem is his history with Sullivan.
Both Poro and Sullivan previously served Derkila, the former demon king. Poro appears to carry some resentment from that period, feeling that Sullivan constantly overshadowed or undermined him. Add in Poro’s intense attachment to Derkila and his anger over the Royal One classroom being used, and suddenly the Misfit Class may not be walking into a neutral judging panel.
That matters because Iruma is Sullivan’s grandson. Even if the other judges play fair, Poro’s personal grudge could make things messy. For a class that has already fought hard to prove it deserves Royal One, that kind of bias would be sakit hati lah.
Purson is no longer just the background gag
The emotional centre of the episode is Purson. For much of the series, he has been the invisible classmate — literally and narratively. Season 4 has been slowly changing that, and episode 5 continues the work of turning him into a fully realised character.
The Misfit Class now knows more about him than just his ability to disappear. They notice his habits, his awkwardness, his musical talent, and the way he struggles under his family’s expectations. That shift is important because Purson’s story is not only about performing well. It is about whether he can claim space for himself.
His conversation with Iruma is especially strong because it balances comedy with a real emotional core. Purson opens up quickly and nervously, unloading his worries and desires, while Iruma quietly recognises parts of his own past in what Purson is saying. Their family situations are not the same, but both characters understand what it feels like to struggle with saying no and to find safety among friends.
That is why this arc hits harder than a standard school festival plot. The music performance is becoming Purson’s chance to show who he is, not just what his bloodline ability can do.
Why SEA fans should keep watching
For viewers in Malaysia and across SEA, episode 5 is a good reminder that Iruma-kun is not just carried by jokes and demon-school chaos. The series works because its emotional beats are easy to connect with. Anyone who has dealt with parental pressure, school expectations, or feeling invisible in a group will understand what Purson is going through.
The Misfit Class trying to protect Royal One is still fun, but the real win here would be Purson standing on stage and being accepted by his friends on his own terms. That is the kind of wholesome character payoff that keeps weekly anime discussions alive in group chats.
