Mairimashita! Iruma-kun [Season 1 Episodes 1-23]

“Welcome to Demon School! Iruma-kun” Season 1: A Wholesome Demon Comedy That Steals Your Heart

Let’s be real—when you hear “14-year-old sold to demons by his parents,” you expect something dark, right? Maybe a horror anime where the kid’s running for his life, or a gritty fantasy about surviving hell. But Mairimashita! Iruma-kun (Welcome to Demon School! Iruma-kun) flips that script so hard it lands in a pile of glitter and demon-shaped cookies. This 2019 anime from Bandai Namco Pictures isn’t about fear—it’s about found family, chaotic friendships, and the kind of humor that makes you snort-laugh into your popcorn. And according to fans on MyAnimeList, it’s exactly what we needed.

First off, let’s talk about the setup because it’s wild. Iruma Suzuki is your typical nice guy—so nice, in fact, that his deadbeat parents sell him to a demon named Sullivan. But instead of being dinner, Iruma becomes Sullivan’s beloved grandson. Cue enrollment at Babyls, a prestigious demon school where Iruma has to hide his human identity while navigating classes like “Demon Etiquette” and “How Not to Get Eaten 101.” Sounds stressful? Nah—this show turns every “oh no” moment into a joke. Like when Iruma accidentally becomes the school’s most popular student because his human kindness reads as “ultra-demonic badassery” to everyone else. Relatable? Maybe not, but hilarious? Absolutely.

The characters are where this anime shines—and fans have opinions. Let’s start with Clara Valac, the pink-haired ball of chaos who’s either your favorite or your biggest pet peeve. “Clara is the best character—she’s annoying, but funny annoying,” says one fan, and honestly? Same. She’s the friend who’d steal your lunch, then sing a song about it while wearing a chicken costume. And don’t even get us started on her musical numbers—yes, there are musical numbers. The Valac family’s random song-and-dance routines are so out of left field they work, even if some fans groan (we see you, haters—you’re just jealous you can’t sing like Clara).

Then there’s Asmodeus Alice, Iruma’s self-proclaimed “servant” who’s basically a demon prince with a flair for drama. At first, he’s all “I will protect you, master!” but by the end of the season, he’s joining Clara’s nonsense and reacting to her antics like a toddler whose ice cream just melted. One fan even pointed out that Azz’s over-the-top reactions (like floating into space in an astronaut suit) are low-key weird—since demons don’t know about Earth—but who cares? It’s funny.

And let’s not forget Ameri Azazel, the student council president who’s low-key obsessed with human manga (don’t tell the demon authorities). She’s tall, tough, and has a secret soft spot for Iruma—and fans are here for their awkward dynamic. “Ameri still hasn’t figured out she’s crushing on Iruma,” jokes one viewer, and honestly? Same energy as when you stare at your crush’s Instagram for an hour then deny it. Their height difference (Ameri’s a giant next to smol Iruma) is iconic—perfect meme material for tall-girl/short-guy couples everywhere.

The comedy here is pure chaos, but it’s the heart that keeps you watching. Iruma’s journey from a kid who can’t say “no” to a demon school legend is all about finding people who love you for who you are—even if you’re a human in a world of horns and tails. Sullivan, his demon grandpa, is the definition of “doting parent”: he’d buy Iruma a mountain of candy, then fight a dragon if it looked at his grandson wrong. The friendship between Iruma, Clara, and Azz feels real too—they bicker, they laugh, and they’d probably die for each other (though Clara would definitely make a song about it first).

Now, let’s address the haters. Some fans say the later episodes have pacing issues, or that the “serious” moments fall flat. And yeah, the Battler’s Arc dragged a little—we get it, not everyone wants to watch demons compete in a sports festival. But here’s the thing: this anime isn’t trying to be Attack on Titan. It’s trying to make you smile, and it succeeds. As one fan puts it, “This show brought me joy—and that’s the most important thing.”

The season finale? Chef’s kiss. It wraps up with a cooking battle between Clara and Azz (because why not?), a final Valac family musical, and a cliffhanger that left everyone screaming: Iruma’s eyes turn red, and he says, “I want to be the Demon King.” Wait, what? Fans are split—some are hyped for “Evil Iruma” in Season 2, others are worried they’ll skip the build-up. But either way, it’s the perfect tease.

Overall, Mairimashita! Iruma-kun Season 1 is like a warm hug with a side of demon jokes. It’s not perfect—some episodes drag, some gags get old—but it’s fun. And in a world where everything feels stressful, fun is enough. As one fan summed it up: “I enjoyed every episode and every minute. 10/10.”

So if you’re looking for an anime that’ll make you laugh, roll your eyes, and maybe even shed a tiny tear (don’t worry, it’s happy tears), give this one a shot. Just don’t be surprised if you start calling your friends “master” or singing demon songs in the shower. We won’t judge.

Now, where’s Season 2? We need more Clara chaos in our lives.

Final Verdict: 8/10—chaotic, cute, and completely worth your time.

P.S. If you’re team Clara, you’re right. If you’re team Ameri, you’re also right. If you’re team “I just want Iruma to be happy,” same.
