Welcome to Demon School! Iruma-kun, Vol. 5
FICKLE FLASH OF FAME
After stealing the show at the Battler Party with his and his friends’ fireworks, Iruma realizes to his dismay that he’s accidentally made himself the center of attention. This first brush with fame quickly earns him the ire of a popular netherworld celebrity itching to ice him out of the picture. As if that weren’t enough, Iruma’s stunt in the spotlight brings him face to face with authorities who present him with an offer he never saw coming: the chance to return to the human realm for good.

Iruma como idol TOP
January 9, 2024
Now that the festival has been saved, it’s time for awkward family interaction! Then, Iruma is in dire need of a boxed lunch, plus we get a look at the idol scene in the netherworld, where Iruma might be a mere 5 feet or less from stardom.
Every time I start a volume of this series I am kind of underwhelmed and feel like this isn’t doing much for me, then I end up being quietly won over by its very earnest and very silly charms.
As I’ve said before - Iruma is a large part of why this series maintains such a strong emotional core. He’s no fool, just predisposed to believe the best of people and to work hard to give people a chance no matter what.
Anyway, festival time commences and we get introduced to the ridiculous brood that Clara calls family (those apples don’t fall far from the tree) and Azz’s mortifying mother. And Iruma, Sully, and Opera wreak havoc doing their own family thing. It’s very charming.
After a brief interlude where Iruma once again confirms his love for the demon world, the volume really gets going. Look, the pairing of Azz and Clara has not yet failed to produce results and watching the sparks fly as they try and make lunches for Iruma is probably my favourite section of this volume.
The next section concerns the idol scene in the demon realm and introduces Kuromu, the most popular idol in the realm. Or that might be re-introduces, since it turns out that she’s been lurking in the manga this entire time.
It’s a pretty fun reveal and her generally shy and retiring persona contrasting with the stage presence she has to manifest is a nice wrinkle, as is the way that Iruma accidentally keeps stepping on her fame.
This whole arc is both incredibly silly - Kuromu’s desperate attempts to keep her identity secret have a great reveal - but also get to the heart of her own insecurities and awkward relationship to her family. It’s got a very solid emotional core, like much of the series.
Naturally this also ends up forcing Iruma and company to form a makeshift idol unit during a time of crisis. Which leads to some pretty amusing drag jokes, not least of which is how into female Iruma his thirsty classmates are (without realizing that it’s Iruma, also naturally).
I don’t love doing recap reviews, necessarily, but Iruma is currently firing off with such consistency that it is laudable, yet also doesn’t give me much to point out that I haven’t already. Yeah, I still wish the art was a touch different, but I’ll live.
4 stars - it’s heart is in the right place and it’s pretty darn funny too. Just keep giving more of this and I won’t complain too much.

I wasn't sure the Valac family would be as wonderful without the singing from the anime, but that was a silly fear - they're still the amazing forces of chaos with or without musical numbers. And apropos of nothing, it occurs to me that if Ameri's father's name is Henri, she's probably supposed to be Amelie. Oh well.

I loved the book it gave a impact-ful story-line.

Ta część jak na razie zrobiła na mnie najmniejsze wrażenie. Pierwsza połowa, wydawało się, że powiela mocno rzeczy z tomu 4, ale na szczęście druga połowa wynagrodziła te mankamenty.

Assez fun la découverte des diablodoles et comprendre un peu mieux le lore autour des démons et de l'enfer. 😈

3.5 || adventurous funny fast-paced
Plot or Character Driven: Plot
Loveable characters: Yes
Flaws of characters a main focus: Yes
Once again, thank you my goat Nishi-sensei for the hilarious deadpan expressions!! It's clear that in this volume, Iruma is blending into the Netherworld both in artstyle as well as in the way he carries himself. The art has "stabilized" so to speak, yet still retains its charms and Nishi-sensei's signature hatching techniques and the insane details in the more tender moments. Though I do think that Iruma's rank ascension did progress rather quickly relative to the entire story thus far (Gimmel at Chapter 35 already!!) but I do understand this felt way longer when waiting for the weekly releases. Still, it's pretty early on and we get that shounen boost so I'm not really one to complain.

Pretty okay volume, would be lower if it didn't have the whole part abt the student body president and Iruma( I ship them so hard). Also lowkey in my brain Az is trans bc Alice to az is some trans shit.
