Welcome to Demon School! Iruma-kun Season 3
Oshimeter
Synopsis
Sold to a demon by his deadbeat parents, human kid Iruma Suzuki somehow landed the best thing that ever happened to him. Now three seasons in, Iruma and his misfit classmates at Babyls Demon School face a new problem: they need to rank up to Dalet before second year or they lose their fancy Royal One classroom. The catch is that ranking up in demon school means surviving stuff like the Harvest Festival, which is basically a competitive free-for-all in a dangerous jungle where everyone's trying to outperform each other. This season leans hard into what makes Iruma-kun work so well: the class dynamic. You've got a whole roster of weirdos who each get moments to shine, and watching them push past their limits to hit that rank goal gives the show a sense of momentum that the earlier seasons were still building toward. The ranking system isn't just window dressing; it actually shapes how characters grow and what they're willing to risk. Bandai Namco Pictures keeps the animation expressive and colorful, which fits the comedic tone without undercutting the moments that carry real weight. If you enjoyed Blue Exorcist's demon school setting or the fish-out-of-water charm of The Devil Is a Part-Timer, this scratches a similar itch. And if Rosario + Vampire left you wanting a better version of "human stuck in monster school," this is the one. Twenty-one episodes across the 2022 run, and the pacing never drags.

A gentle finale with just enough tension under the surface. The final reveal is a fantastic hook. Season 3 ends warmly, but with the next problem already waiting.
A sweet cooldown episode with two good halves. Light, charming, and a nice breather before the finale.
This episode shifts from cozy teacher banter to genuine menace. The faculty scenes are fun, but the reveal at the end changes the vibe fast. Good set up!
The Legend Leaf payoff is delightfully ridiculous. After all that buildup, the goofy reveal is perfect. Silly, triumphant, and surprisingly emotional.
A warm victory lap after the exam madness. Promotions, celebration, embarrassment... It is mostly payoff, but the emotional reward lands because the season made the whole class matter.
The festival climax is full of teamwork, tricks, and last-second reversals.The whole class quietly backing Iruma feels earned. A smart, exciting setup for the final push.
A very strong Clara episode. You'll like it if you want to know more about her character. Great payoff for the friend group.
Lead getting emotionally WRECKED is both hilarious and kind of tragic. This episode is mostly setup, but it keeps a lot of moving pieces entertainingly chaotic.
The giant vine moment is great, and the episode keeps the pressure on. Momentum stays high. Exciting ep!
One of the better Iruma-center episodes. Watching him fight through that fear was satisfying.
Toto is the kind of goofy detour this series does really well. The challenge stays tense, but the solution is pure Iruma-kun nonsense.
Ameri’s total faith in Iruma is adorable. The season starts feeling bigger and more purposeful here.
Hype episode, we love an evil cycle episode. Asmodeus and Sabnock finally become a workable disaster duo! Great episode
A strong ensemble episode that shows just how differently every pair has adapted. Fun episode!
This episode is hilarious and weirdly sweet. Clara’s Toy Box is a perfect Clara ability: playful, overwhelming, and hiding real feelings under nonsense. I personally don't really care about shipping, or ClaraxIruma but if you are into that maybe there is something for you?
Iruma’s survival-first strategy is so smart it loops back around to being funny. A wonderfully chaotic episode.
Jazz and Allocer get one of the season’s coolest side stories. This episode proves Season 3 is not just Iruma’s show; the whole class gets room to shine.
A relaxing and entertaining start to the series. The mix of fantasy adventure and cooking makes it unique and enjoyable to watch.
The Harvest Festival begins with exactly the right mix of excitement and menace. Everyone feels stronger, stranger, and more dangerous than before. Great ep!
Ending the episode with such a hooking cliffhanger was a brilliant way to keep you engrossed in the story's direction & its further revelations for the entire arc. Moreover, it’s truly heartwarming how their solidifying friendship was deeply foregrounded throughout their journey.
