reirei★★★★☆VerifiedEP 18I liked this episode. It was light-hearted and funny from beginning to end. The grandparents were definitely the highlight, making everything so chaotic and hilarious at the same time, lol. I loved those scenes!
Iruma Suzuki is only 14 when his deadbeat parents sell him to a demon, which sounds horrifying until you learn the demon in question is basically the world's most doting grandpa. Iruma now lives in the Netherworld, attending Babyls School for Demons while desperately trying to hide the fact that he's human, which, in a world of demons, is basically being a walking snack. He's flanked by Asmodeus, a noble demon who's sworn undying loyalty to him after losing a fight, and Clara, who has the energy of a golden retriever that found coffee. The fourth season picks up with the Music Festival Arc, where Iruma's entire Misfit Class needs to hit Rank 4 together. That means all thirteen of them, including the ones who can barely function in normal society. The show's strength is how it builds out each classmate with their own Bloodline Magic and personal hang-ups, then finds ways to make you genuinely care when they level up. Bandai Namco Pictures keeps the animation bright and expressive, and the demon world design stays inventive without ever feeling generic. If you liked Blue Exorcist's demon school setting or the fish-out-of-water comedy in The Devil Is a Part-Timer, this scratches a similar itch but leans harder into the warmth. Fans of Rosario + Vampire's "human in monster school" setup will feel right at home too, though this one's more wholesome than horny. Three seasons in and it hasn't lost momentum. that's rare for shounen.

katana★★★★★VerifiedEP 18It was an entertaining episode, and I really liked the chemistry between the three grandsons, lol. The second half was especially adorable! Clara was hilarious, and I loved seeing the trio get the spotlight again. It was just so wholesome.
sandaime★★★★★VerifiedEP 18This whole episode was so cute and light-hearted while also building some anticipation for the future Demon King. Iruma was hilarious, and the whole concept of the Demon King's traits wasn't even that demon-like, which made everything even sillier.

tsubasa★★★★☆EP 18First half was great. Second half is ok - just feels like more filler. Pacing has always been weird with Iruma. I do like that they explained why the demons gather to eat and how that showed their greed.
jeerox★★★★★EP 18A banger episode where the foreshadowing of Iruma came to life. And still, everytime i see the foreshadowing gives me goose bumps. A very entertaining episode where demons aura are of fire. But yeah it was still fun watching the episode.
fedel89★★★★★EP 18Episode lacked something. I needed more plot for the demon kin candidate. Now the next part of the episode are just fun and games. Though all in all, I enjoyed it!
fedel89★★★★★VerifiedEP 17Really really exciting! Finally getting to the intense part! Will there be really a chosen one? For me, this is a cliffhanger episode! But at least we get to see some "Candidates" for the you know what! Haha!
akumapulse★★★★☆EP 18Episode 18 of Welcome to Demon School! Iruma-kun Season 4 shifts into a more relaxed, cooling-down phase following the explosive energy of recent weeks, focusing on aftermath recovery, lighter comedic interactions, and quiet character reflections. By slowing down to let the cast breathe, the episode provides a gentle palette cleanser while navigating the shifting dynamics of the school. The pacing is steady, moving through its beats at a comfortable clip without the same propulsive energy that carried the last installment. It occasionally feels a bit stretched as it moves through standard transitional beats and lower-stakes gags — not sluggish, but noticeably more subdued. Visually, the episode remains a strength. The production stays bright, clean, and expressive, maintaining the series' signature colorful aesthetic and lively character designs even during quieter conversation scenes. The show's distinctive charm comes through clearly, even without straying far from its established visual style. The writing is serviceable this time, leaning heavily on familiar filler tropes and predictable situational comedy, offering minimal overarching plot progression while keeping the focus entirely on comforting character fluff. It keeps the cast's dynamics ticking along, though it leans more on familiar beats than offering much that feels fresh or surprising. Emotionally, the episode lands reasonably well without reaching for anything particularly heavy. The impact is mild and cozy, providing a pleasant sense of camaraderie without attempting any heavy dramatic punches — a few warm moments that keep things pleasant if not especially memorable. The soundtrack fits the tone competently, with a cheerful and dependable quality that matches the lighthearted atmosphere smoothly, keeping things warm and approachable without doing much to stand out on its own. Taken together, it's a comfortable, low-stakes cool-down episode that gives the cast a well-deserved breather. While it lacks the soaring highs of the arc's major centerpieces, its casual charm makes for a pleasant, easygoing watch — a bit of a step down in energy from the previous episode, but still a solid part of the season.
akumapulse★★★★☆VerifiedEP 17Episode 17 of Welcome to Demon School! Iruma-kun Season 4 dives headfirst into high-energy spectacle and joyous chaos, capturing the absolute best of the series' vibrant identity. Balancing grand-scale festival antics with deeply satisfying character moments, the episode delivers a relentlessly entertaining ride that keeps the excitement peaking from start to finish. The pacing is the clear highlight. It's swift and expertly managed, maintaining a lively rhythm that seamlessly zips through comedic beats, rapid-fire dialogue, and show-stopping highlights without ever letting the energy dip — a tightly constructed, thoroughly engaging rhythm from start to finish. Visually, the production shines with bright colors, expressive character reactions, and dynamic choreography that bring the chaotic atmosphere to life. It's clean, expressive, and full of the charm that suits the show's distinctive tone, even if it doesn't push far beyond the series' established visual identity. The writing delivers engaging progression for the ongoing arc, keeping the narrative lively by giving various fan-favorite characters their time to shine. It still relies on comfortable series tropes, but the cast's interactions land well and the show's blend of humor and heart stays intact throughout. Emotionally, the episode strikes a warm, satisfying balance, leaning into genuine camaraderie and triumphant payoffs that make you root for the cast. The character moments carry real charm, even if the episode doesn't reach for anything particularly heavy this time around. The soundtrack punctuates the comedic and heroic moments perfectly, matching the high spirits of the narrative and providing pleasant, fitting atmosphere throughout, even if it doesn't become especially distinctive on its own. Altogether, it's a thoroughly delightful, high-momentum installment that showcases the series at its most fun. With stellar pacing and infectious energy, it stands out as one of the stronger entries of the season — a genuinely enjoyable watch and a major highlight of the current arc.
vamplier★★★★★EP 18Gracias a todos los dioses por otro maravilloso capítulo de este maravilloso animé. Un punto de desarrollo serio de la trama, pero en realidad no, y el trio de Iruma se prepara para su segundo año, pero en realidad no. Un capítulo divertido, hermoso y emocionante.
frostsincere★★★★★EP 18It was another funny ep again. The gramps were so funny, their reactions got me laughing the whole time. And the trio bonds were really heartwarming and pure comedy. Asmodeus was really funny, i even thought that he might malfunction anytime lmao. Clara was really good tho, i think it suits her.

vamplier★★★★☆VerifiedEP 17Otro capitulo maravilloso de esta serie maravillosa. Lo que prima es la presentación de personajes. Personajes maravillosos por cierto. Comienza la selección del próximo rey demonio y los 13 empiezan a mostrar sus cartas.
robert_rifle★★★★☆EP 17Baal is definitely planning something dirty with that secret nomination he mentioned and you can tell the other crowns are already suspicious of what he is up to
vincent_valentine★★★★☆EP 17The way they introduced Berry and Leiji was so cool and you can really see how their upbringing at those specialized schools shaped their crazy personalities compared to the babyls crew
ortega★★★★☆EP 17The internal conflict for Henri and Amuryllis while they watched their kids really got to me, because you can tell they want the best for them but also fear that kind of responsibility
ancient_robot_295★★★☆☆EP 17Leiji carving giant sculptures and ignoring all the school rules is the exact kind of chaos you want from a top tier demon candidate and he makes a perfect rival for Iruma
kittan_bachika_188★★★★☆EP 17I was actually nervous for Iruma when he got tied up for that interview because those thirteen crowns members look completely different when they are being serious and judgmental toward the kids
jushiro_jubei★★★★☆EP 17This gathering felt so much bigger than the school festivals you usually see, because the entire future of the netherworld is actually on the line now and seeing Iruma stand between those two terrifying grandsons while holding his own was great and it is cool that Sullivan wants to nurture the next king, instead of just picking the strongest one
