Meet the characters from Welcome to Demon School, Iruma-kun!

Iruma Suzuki

Iruma is this endlessly earnest, awkwardly charming human stuck in a demon school — he’s basically kindness personified and also incredibly accident-prone. He adapts to absolutely anything by smiling until the situation calms down, and then panicking inside (big energy). He’s wildly loyal, surprisingly brave when it matters, and also hilariously bad at subtlety — like, he’ll try to be sneaky and somehow everyone knows. His role is that warm, baffled heart of the story who somehow makes friendship into a superpower.

Alice Asmodeus

Alice is a flashy, scheming aristocrat-type with too much confidence and zero chill, in the best way possible. He’s fiercely protective of his friends, especially Iruma, and will analyze a problem like it’s a chess match while wearing a ridiculous grin. He’s vain and theatrical but also collects tiny sentimental things (I swear I saw him tuck a pebble into his pocket once), so he’s not all bluster. Basically, equal parts strategist and softie who will roast you for fun and then dramatically defend you five minutes later.

Ameri Azazel

Ameri is pure regal intensity — student-council-through-and-through, poised, terrifyingly composed, and somehow also a romantic lead who blushes at the slightest thing. She runs things with that iron-clad dignity that makes even the hallways feel judged, but she has these adorably awkward cracks where she smiles like a lunatic at cute things. She’s strict yet secretly sentimental (cookies will make her melt, don’t tell), and she has this mysterious aura that’s 90% drama, 10% soft heart. Honestly, you respect her, fear her, and want to hug her all at once.

Clara Valac

Clara is the human balloon of pure chaos — she screams, she giggles, she flails, she’s everywhere and also somehow the most reliable wreck of energy you’ve ever seen. She’s wildly imaginative and zero-filter, which means she’ll invent a game involving glitter, a broom, and a conspiracy theory in under a minute. She’s also oddly perceptive; she’ll jabber nonsense and then drop this dead-on observation about you like she read a manual. Total unpredictable friend energy — part tornado, part teddy bear, full-speed adorable.

Kalego Naberius

Kalego is the grumpy, sharp-tongued teacher who terrorizes and refines everyone at once — sword-level sarcasm, huge brain, low patience. He’s the classic “I’ll beat you with knowledge” type; strict, intimidating, and secretly doing oddly compassionate things at midnight (regrading papers with a scowl and a tiny smile). He alternates between disciplinarian and mentor in ways that make you suspicious he’s a walking paradox. Basically, terrifyingly efficient with a soft underbelly he would absolutely deny having.

Sullivan

Sullivan is theatrical in the best, loudest sense — huge, flamboyant, and impossibly kind; he adopted Iruma and then became this grand, chaotic dad figure who lives for dramatic entrances. He runs things like a benevolent carnival master: confetti, fanfare, booming laughter, and then unexpectedly quiet moments where he’s just…soft. He’s generous to a fault, fiercely protective, and also absurdly dramatic about small things (somebody touched his hat and the world ended for a minute). He’s basically a walking, talking parade float with a surprisingly tender core.

Opera

Opera is deliciously theatrical — she treats life like a stage performance, speaks in majestic pauses, and is never without an outfit that could headline a show. Mysterious and a little spooky, she has that refined glamour but also an odd whimsical streak (maybe she collects spoons? maybe she doesn’t, who knows). She switches between hauntingly composed and delightfully eccentric, so you can never predict which Opera you’ll get that day. She’s dramatic, stylish, and probably judging your playlist while offering you a biscotti.
