Mairimashita! Iruma-kun [Season 1-3]

“Welcome to Demon School! Iruma-kun”: A Wholesome Demon Comedy That Feels Like Saturday Morning Cartoons

Let’s be real—when you hear “14-year-old human sold to demons,” you probably picture something dark, edgy, or straight-up terrifying. But Mairimashita! Iruma-kun? It’s the exact opposite. This anime is like if your favorite childhood Saturday morning cartoon got a demon-themed glow-up—colorful, chaotic, and so wholesome you’ll forget it’s set in the Netherworld. Over three seasons, it’s carved out a spot as one of the most beloved feel-good comedies in recent years, and after binging all the episodes, it’s easy to see why.

First, let’s get the basics straight. Iruma Suzuki is your average overworked kid—until his deadbeat parents sell him to Sullivan, a powerful demon who’s been lonely and desperate for a grandchild. Instead of being his slave, Sullivan dotes on Iruma like he’s the crown prince of the Netherworld, enrolling him in Babyls Demon School where Iruma has to hide his human identity (spoiler: demons have no clue Earth exists, so this is harder than it sounds). The premise sounds wild, but the show leans into the absurdity so hard it works. It’s not about Iruma fighting for survival—it’s about him navigating demon exams, making friends, and accidentally becoming the most popular kid in school without even trying.

What makes Iruma-kun stand out is its cast of characters. Let’s start with Clara Valac, the pink-haired ball of chaos who’s either your favorite character or your biggest pet peeve (no in-between). She’s loud, hyper, and breaks into song at the drop of a hat—like that time her entire family performed a musical number about… well, being demons? Fans are split: some call her “funny annoying” (shoutout to the Reddit user who said she’s “infecting Azz with her antics”), while others find her “fucking annoying” (sorry, Clara stans). But love her or hate her, she’s the heart of the show’s humor—her random outbursts and obsession with Iruma keep every episode from feeling stale.

Then there’s Asmodeus Alice (Azz), Iruma’s self-proclaimed “servant” and the most dramatic demon you’ll ever meet. He starts off as a stuck-up rich kid who only cares about power, but by the end of Season 1, he’s dressing up in astronaut suits to react to Clara’s nonsense (yes, really). Their dynamic is pure gold—Azz’s seriousness clashing with Clara’s chaos is like watching a cat try to herd a hyperactive dog. And let’s not forget Ameri Azazel, the student council president who’s secretly a huge fan of human manga (she thinks Iruma’s “human quirks” are just him being a “cool delinquent”). Her crush on Iruma is so obvious it’s painful—she blushes every time he talks to her, and fans are begging for their relationship to develop in Season 2 (one MyAnimeList user even joked about their “tall-girl/short-guy” dynamic being iconic).

The show’s humor is what hooks you. It’s silly, slapstick, and full of running gags—like Sullivan’s over-the-top grandpa antics (he once turned into a giant teddy bear to hug Iruma) or the Valac family’s musical numbers that come out of nowhere. One fan compared it to “Saturday morning cartoons from my childhood,” and that’s spot-on. It’s the kind of show you can put on after a long day and just laugh—no complicated plot twists, no dark themes, just pure fun. Even the “serious” moments (like Iruma accidentally summoning a demon king-level power) are played for laughs, which is a breath of fresh air in a genre full of edgy demon stories.

But Iruma-kun isn’t just about jokes. It’s surprisingly wholesome. Iruma’s journey from a kid who’s never been loved to someone surrounded by friends who would do anything for him is heartwarming. Sullivan’s love for his grandson is genuine—he cries when Iruma calls him “grandpa,” and he’ll do anything to keep Iruma safe. Azz and Clara’s friendship with Iruma is also sweet—they accept him even when they (eventually) find out he’s human, which says a lot about the show’s message: that family and friends are what matter most, no matter where you come from.

Of course, it’s not perfect. Some fans think the later seasons suffer from pacing issues—one MyAnimeList user said the “battlers arc felt a bit boring.” Others find the musical numbers cringy (sorry, Valac family stans). And let’s be real—some of the jokes are hit-or-miss. But for every flaw, there’s a moment that makes you smile. Like when Iruma stands up for his friends, or when Azz finally admits he likes Clara’s antics, or when Ameri geeks out over human manga. These small, sweet moments are what make the show special.

The ending of Season 1 left fans screaming. After a chaotic final episode (complete with a cooking battle between Azz and Clara), Iruma’s eyes glow red, and he says, “I want to be the Demon King.” It’s a cliffhanger that had everyone begging for more—one fan even wrote, “I need Season 2 now!” The setup for future seasons is exciting: will Iruma embrace his demon side? Will Ameri find out he’s human? Will Clara ever stop singing? We don’t know, but we can’t wait to find out.

Overall, Mairimashita! Iruma-kun is a must-watch for anyone who loves feel-good comedies. It’s not groundbreaking, but it’s fun, wholesome, and full of heart. As one fan put it, “This show brought me a lot of joy and fun—and that’s the most important thing in an anime.” Whether you’re a kid or just a kid at heart, this demon school comedy will make you laugh, smile, and maybe even wish you could attend Babyls (minus the whole “hiding your human identity” thing). So grab some snacks, sit back, and let Iruma, Clara, and Azz take you on a wild ride through the Netherworld—you won’t regret it.

Final Verdict: 8/10. It’s not perfect, but it’s the kind of show that will leave you feeling warm and fuzzy inside. And let’s be real—we all need more of that in our lives. Now, if you’ll excuse me, I’m off to rewatch Clara’s musical numbers. They’re cringy, but I can’t help it—they’re catchy.

P.S. Clara is best girl. Fight me.
