My Sweet Piano has been Hello Kitty's best friend since first grade. She is endlessly cheerful, talks to almost everyone she meets, and can get excited over almost anything.

Pochacco

Soccer Team Captain · School Heartthrob

Pochacco is the chill athletic heartthrob of Sanrio High — the kind of person everyone notices the moment he walks into a room. He's My Melody's ex, which makes things complicated now that Hello Kitty is on the scene. Hello Kitty caught a glimpse of him on her first day and couldn't look away. He's interested in her too. My Melody noticed.

Badtz-Maru

Senior · Pochacco's Right-Hand Man

Badtz-Maru is one of the coolest guys at Sanrio High — confident, funny, and effortlessly popular without even trying. He's sassy, witty, and sometimes completely chaotic, always ready with a sarcastic comment before you even finish talking. Don't let the attitude fool you though. The moment someone outside the group gives his friends a hard time, he's the first one to step forward. He acts tough, but he's fiercely loyal.

My Melody

School Queen Bee · Pochacco's Ex

My Melody is the queen bee of Sanrio High — polished, popular, and not used to losing anything she considers hers. She broke up with Pochacco, but she definitely noticed when he started paying attention to the new transfer student. Her response to finding Hello Kitty's open locker on the first day? A quiet "Oh...nothing." To be continued.

Personality: Sweet on the surface, calculating underneath

Kuromi

Senior · Sanrio High's Rebellious Trendsetter

Kuromi is the most fearless girl at Sanrio High — sharp-tongued, mischievous, and completely unbothered by what anyone thinks of her. She lives in Y2K fashion, stays on top of every K-pop release, and always has a comeback ready before you finish your sentence. She and Badtz-Maru are constantly roasting each other and pulling pranks, and it somehow works perfectly. Don't mistake her edge for coldness — if someone messes with one of her people, she is the first one stepping forward.

Cinnamoroll

Art Club Star · Pompompurin's Best Friend

Pompompurin

Pochacco's Circle · Cinnamoroll's Best Friend

Laid-back and lovable, Pompompurin somehow always ends up napping at the exact moment he's needed — yet always shows up for his friends when it counts. He's part of Pochacco's main circle alongside Badtz-Maru and Keroppi, and best friends with Cinnamoroll in the way that just makes sense.

Wish Me Mell

Greenhouse Club · Top of Her Class

Wish Me Mell is one of the smartest students at Sanrio High — the kind of girl who studies ahead, takes perfect notes, and still finds time to tend the greenhouse before first period. She's mostly soft-spoken and focused, but has a bubbly side that comes out around the people she trusts. Her biggest weakness? Mocha — the school heartthrob who drives her absolutely crazy, and she wouldn't have it any other way.

Circle: Marroncream, My Sweet Piano — quiet afternoons in the greenhouse or tea parties between classes
Dating: Mocha — she fell first and fell hardest; she sees through his arrogance and quietly refuses to let him get away with it

Tuxedosam

Drama Club Star · The Fabulous One

Tuxedosam is the most theatrical student at Sanrio High, and he knows it. Whether he's commanding the stage, critiquing someone's outfit mid-hallway, or launching into a full performance to make a point, Sam does nothing quietly. He's mastered five accents, has an opinion on every fit, and somehow still manages to be friends with absolutely everyone — because underneath the drama, he's completely genuine.

Circle: Friends with everyone — especially My Melody, who is the only one who can calm him down mid-monologue
Known for: Five-accent repertoire, unsolicited fashion critiques that are somehow always right, and making any situation a performance
Personality: Hardworking, over the top, loud, funny, and dramatically fabulous — takes his craft seriously even when no one else does
Favorite subject: Drama Club

Cogimyun

Magical Girl · The Enchanting One

Cogimyun looks like the sweetest, softest thing to ever walk the halls of Sanrio High — and she is — but don't let that fool you. She is a magical girl with a television career, a wand collection, and a level of savagery that surprises everyone who underestimates her. She's technically supposed to be saving the world on weekends, but she keeps finding reasons to stick around school and help people instead. She loves it here.

Personality: Cute, magical, surprisingly savage, loves reading, deeply caring — somehow ageless even though she is very much a teenager
Favorite subject: Cloud Chemistry

Mocha

Campus Heartthrob · The Effortlessly Cool One

Mocha is the guy everyone notices without him even trying. He's laid-back, athletic, and way too comfortable coasting — whether that's on the field, in the halls, or mid-scroll on his phone. He's not exactly motivated to do much, but he's got Wish Me Mell in his corner, who is somehow the one person who actually gets through to him. They're not officially together. Everyone knows they basically are.

Circle: Always seen with his dog (who rocks shades better than anyone), and low-key inseparable from Wish Me Mell
Known for: His hair, his sunglasses collection, and doing the absolute minimum while still somehow looking good doing it
Personality: Chill, athletic, effortlessly cool — not great at school, but working on actually caring (Wish Me Mell's influence)
