Welcome to Demon School! Iruma-kun Season 4

Yeah, so Season 4 of *Welcome to Demon School! Iruma-kun* is here, and honestly? Babyls still feels less like a proper demon school and more like a place that specializes in turning regular school stuff into absolute chaos. And I’m not even mad about it. Quick recap if you’re new: Iruma’s parents are the worst. Genuinely awful. They straight-up sell him to a powerful demon named Sullivan. But instead of becoming dinner, Iruma gets adopted by this ridiculously doting grandpa figure and ends up at Babyls, a school full of demons who would probably eat him if they ever found out he’s human. What started as pure survival mode has somehow turned into one of the warmest found-family stories around. Wild how that happened. This season is mostly the Music Festival arc. The whole Misfit Class—all thirteen of them—have to hit Rank 4 or they lose their special classroom and all the good stuff that comes with it. Their big plan? Put on a school performance that doesn’t completely bomb. Imagine your entire future hanging on one talent show. That’s these kids right now. And finally, after three seasons of basically being a background ghost, Purson Soi gets actual screen time. The quiet kid whose whole thing is staying invisible finally steps up, and his story about wanting to be seen hits way harder than it has any right to. The class is still the best part. Iruma remains the softest, most earnest protagonist out there, slowly figuring out what he actually wants instead of just reacting to everything. Azz is still ridiculously devoted. Clara is still pure chaos in human (well, demon) form. And the rest of the group just vibes in the best way. Their friendships feel real, and watching them try to pull off this performance together is genuinely fun. Purson’s arc is the real win of the season. Turning a three-season gag into something with actual heart is peak *Iruma-kun*. The Music Festival itself is the highlight. It’s not about some world-ending threat. It’s just a bunch of weirdos figuring out how to work together, push past their own stuff, and put on a show. Somehow that ends up being more satisfying than half the high-stakes anime out there. That said, the pacing can drag a bit. Twenty-four episodes is a lot for what basically feels like one main arc plus some extra. There are stretches where it’s just the class being goofy for a while, and while it’s charming, you sometimes wish they’d pick up the pace. The Dem-Dol Games stuff is fun for a change of scenery, but it also kind of overstays. And yeah, the “Iruma is so nice that everyone’s problems get fixed” formula is still going strong—you can see the pattern pretty clearly by now. Animation-wise, it’s the same colorful, expressive style as always. Nothing mind-blowing, but the faces and comedy timing still work great. The music fits the vibe too, especially the festival numbers. Overall, Season 4 is another solid, cozy entry. It doesn’t try to reinvent itself, and it doesn’t need to. The characters are still lovable disasters, the heart is still there, and I’m somehow still emotionally invested in a classroom full of demons and one very overwhelmed human kid. If you’ve been riding with the series this long, you’ll probably have a good time. Just maybe don’t expect every episode to fly by. Still rooting for these weirdos. Somebody give Iruma a normal weekend already.

I hope it has more singing in this season. But it fun to watch. Let's see who is demon king

Sabro telling Baal he wants to win fair and square because he has rivals and friends at Babyls. That's the whole show in one line for me. The uncle stuff got tense as hell though

This is a great kickoff for the series' new arc, showcasing vibrant colors and an engaging, high-stakes buildup for the story centered on the exciting demi idol plot arc. I can't wait to see how this narrative will unfold with even more highly anticipated highlights. On top of that, the characters involved bring a lighthearted, amazingly energetic dynamic that genuinely excites me.

Final episode and now need to wait for new season again. Nooooo!

wait for long for this

amazingly

the way Derakila just casually tried to move a river because he felt like it is the funniest flex in demon history. no wonder Iruma looks at that and goes boy I got a lot to live up to

Sabro turning Baal down because a shortcut would be uncool and disrespectful to his rival is the whole reason this guy is worth rooting for

I was waiting all season for Sabro to get a real spotlight episode and this delivered. Him turning down Baal's shortcut is the payoff for all the growth since season one and it makes sense because of the friendships he built at school. The quiet part is what got me though. That shot of him and Iruma just lying on the library floor with books everywhere. No fighting no jokes just two kids who love the same legend. Then Baal shows up and the whole tone flips. You feel how dangerous it is for Sabro to say no to a member of the thirteen crowns and he does it anyway

As the episode progresses, the character dynamics certainly showcase the amazing energy and chemistry of Team Devimuse, which effectively delivers a highlighted comedic reaction and a fast paced approach that makes this story buildup incredibly entertaining. Plus, Merie-chan and Lindy add a wholesome flavor to the episode's plot. And the ending was totally intriguing and hooking!!!!!!

Maravilloso anime de principio a fin. Hay para todos los géneros pero en esta temporada destaca especialmente la música. Maravillosa animación y 0 sentido común.

A final episode that teases an even flashier sequel. I don't have any complaints about this season or the past ones at all, it’s just banger after banger. I'm really looking forward to the next season, since it will really put the studio's animation to the test and show how they adapt a certain hair-raising arc. Tbh, they’re all hair-raising, but one particular arc is definitely worth anticipating.

Tantas temporadas y nunca he logrado entender que le pasa a Baal.

Baal calling Sabro weak for having morals is exactly what the old Netherworld would do. Sabro choosing his friends over a shortcut is the new one. Kirio smiling at the end gave me chills

I didn't expect to care this much about Sabro's family drama. Silvia jumping on his back got me. Then Baal walked in and the whole room went cold. My mood flipped that fast

I did not expect to care this much about a library scene but the two of them just lying on the floor with books everywhere as the sun went down got me

the post credits bit with Silvia attacking Yamanda while he tries to pour tea cracked me up. endurance training apparently means jumping your butler

the music festival stuff was fun but this slower lore episode is what I wanted all season. the political stuff with Baal and the thirteen crowns has been building forever

Kirio showing up at the end with that smile again. Of course he's with the six fingers. That kid was never done being a problem
