The Characters of Sanrio High
Hello Kitty

Hello Kitty

New Transfer Student · The Heart of the Group

Hello Kitty just transferred to Sanrio High alongside her lifelong best friends My Sweet Piano and Dear Daniel. Adjusting hasn't been easy — she's got a temper that flares and a roar that surprises people. But underneath all of that is one of the kindest hearts you'll ever find. She's the glue that holds her whole crew together, even when she doesn't realize it. She's deeply emotional underneath it all, and that same open heart is what lets her become friends with nearly everyone she meets. When the fighting reaches the Metaverse, she's right there on the front lines, and off the battlefield she's become known for her solo songs — "Heart," "The Girl," and many more. Her love for Dear Daniel runs so deep that she gives up half of her own light heart to save him, a sacrifice that ultimately pulls her toward darkness. She cuts her hair short afterward, a quiet but unmistakable act of rebellion against the person she's expected to be.

My Sweet Piano

My Sweet Piano

Hello Kitty's Best Friend · The Energetic One

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. She had a habit of making friends within minutes, even if she had just met someone. And yes — she will forget her water bottle every single day. She's dating Buppi, who she had a huge crush on long before they got together — a crush that only grew after he gave her his own jacket when she was cold. After becoming a minor character from Season 1 onward, her love of art never faded — she goes on to become a famous artist and a teacher, passing everything she knows on to the next generation.

Dear Daniel

Dear Daniel

Hello Kitty's Best Friend · The Calm One

Dear Daniel has been Hello Kitty's best friend since middle school. He's calm, easygoing, and usually the one keeping everyone on schedule. Unlike Piano, Daniel never tries too hard to impress anyone. He showed up on the first day of Sanrio High in his baby blue compact car, ready to drive the group to wherever the story was headed. Later on, Daniel becomes immortal, ascending to godhood and making his home in the Metaverse, where he spends his time helping those who need it. He does feel the weight of letting Hello Kitty go, but in the end he's genuinely happy for her — and for Hangydon.

Pochacco

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

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

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.

  • Trio: The Queen Bee Trio — with Kuromi & Cinnamoroll
  • Ex: Pochacco — broke up with him, but she's definitely not over it and still wants him back
  • Personality: Sweet on the surface, calculating underneath
  • Favorite subject: Fashion Club
Kuromi

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. She looks up to her big sister Romina more than anyone, and underneath the attitude, she's determined to find her — Romina left behind only a note saying she's on a gem island that appears on no map.

Cinnamoroll

Cinnamoroll

Art Club Star · Pompompurin's Best Friend

Cinnamoroll is dreamy, gentle, and always seems slightly elsewhere — but in the best way. Her art pieces always end up on the school bulletin board, and she blushes every single time someone points it out. Her and Pompompurin are inseparable in the way only true best friends can be.

Pompompurin

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. He's dating Macaroon, who keeps him on his toes.

Keroppi

Science Club · Pochacco's Circle

He's part of Pochacco's main circle and somehow manages to be friends with absolutely everyone at Sanrio High. He's proud of how far he's come and keeps pushing forward — and the Lily Pad family keeps growing right along with him, ever since their inheritance.

Wish Me Mell

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

  • Favorite subject: Culture of Cute History
Tuxedosam

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.

Cogimyun

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

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

Macaroon

Cheer Team · Field Hockey Tomboy

She'll spend her whole allowance on macaroons without a second thought, and she's dating Pompompurin.

Baku

Baku

Kuromi 5 · Rebellious Anti-Hero

Baku is the school's resident anti-hero — casual, arrogant, and always working an angle. He's constantly making deals, scamming people out of their money or their homework, and never misses a chance to call someone "sucka." He's part of the Kuromi 5, where he flirts shamelessly with Kuromi because, as he puts it, she's pretty and she's the leader. He loves spray painting, messing with others, and bragging to his friends about how he single-handedly saved the school — whether anyone believes him or not.

  • Group: Kuromi 5
  • Best friend: Berry (who he constantly tells to shut up)
  • Loves: Spray painting, scamming others, messing with people
  • Personality: Rebellious, arrogant, casual, a scammer at heart
  • Favorite subject: None
Berry

Berry

Kuromi 5 · Baku's Biggest Fan

Berry is a punk at heart and Baku's self-appointed best friend — whether Baku likes it or not (he doesn't). Berry idolizes him completely, never stops talking, and has zero concept of personal space, hugging Baku at every opportunity he gets. He runs his own magic show in the auditorium, loves pulling pranks, and is a proud member of the Kuromi 5. He's also been secretly keeping a time capsule full of Baku memorabilia, which disturbs Baku deeply every time it comes up. He's dating Cherry, who he adores completely — though she's not afraid to slap him when he starts adoring Baku more than her.

  • Group: Kuromi 5
  • Best friend: Baku (who can't stand him, though Berry hasn't noticed)
  • Dating: Cherry
  • Loves: Pranks, magic, running his magic show in the auditorium
  • Personality: Punk, talkative, clingy, idolizes Baku
  • Favorite subject: Whimsical Club
Cherry

Cherry

Kuromi 5 · The School's Resident Witch

Cherry is a witch, through and through — she brews her own potions, has taught herself teleportation and floating, and has a creepy little giggle that makes people nervous for good reason. She's the least known member of the Kuromi 5, but the fans who do know her love her the most. She practically lives in the library to skip class, and has claimed the Dragon Domain Ruins section as her own personal hideout. She loves motorcycles and reading, is dating Berry, and doesn't hesitate to slap people when she's bored.

  • Friends: Kuromi, Nyanmi, Baku, Berry, Wanmi, Konmi
  • Loves: Motorcycles, reading, potions, the library's Dragon Domain Ruins
  • Skills: Teleportation, floating, a creepy giggle
  • Personality: Mysterious, witchy, easily bored, slaps first and asks questions never
Pandapple

Pandapple

The Peaceful Panda Lover

Pandapple is one of the gentlest souls at Sanrio High. He's rarely seen without his beloved panda, Bobo, and he'd rather spend an afternoon apple picking in the orchards than anywhere else. He loves the meadows, gets lost in a good book, and is happiest baking or cooking up something with apples. He's friends with Keroppi and has had a quiet crush on Hello Kitty for a while now, though he'd never admit it outright.

  • Friends: Keroppi
  • Crush: Hello Kitty
  • Loves: Apple picking, orchards, meadows, reading, baking with apples

Buppi

Buppi

The Underrated Soccer Lover

Buppi is a friendly, down-to-earth guy who lives and breathes soccer — he just wishes more people at school were as invested in it as he is. He's kind through and through, the kind of person who'll hand over his own jacket the second he notices someone's cold, which is exactly what he did for My Sweet Piano, who's had a huge crush on him ever since. The two are now dating. He's underrated around school, but anyone who actually knows him knows he's a great guy at heart. He loves fish and seafood dishes, is naturally athletic, and is close friends with Keroppi, Dear Daniel, and Pandapple.

  • Dating: My Sweet Piano
  • Friends: Keroppi, Dear Daniel, Pandapple
  • Loves: Soccer, fish and seafood dishes

Retsuko

Retsuko

Transfer Student · Student Council

Retsuko transferred to Sanrio High from Aggretkotsu Academy, and she's quickly become known as fast, kind, smart, and a dedicated member of the student council. Her past wasn't easy — she was bullied, and it was her friends Haida and Fenneko who helped her through it. She still carries a temper and once battled real depression, but she's learned to keep both in check. One of her favorite outlets is death metal karaoke. She had a long-running rivalry with Hello Kitty, the two of them framed as rival faces of their story, which eventually built into a full competition — but the rivalry turned into friendship, and Retsuko invited Haida and Fenneko to Sanrio High, who arrived on a flying vehicle. These days, all Retsuko really wants is a relaxing vacation. She loves pizza and strawberry-drizzled milkshake ice cream, enjoys typing and reading newspapers, and is dating Haida — a relationship that eventually leads to marriage once they're grown up.

  • Dating: Haida (they later marry as adults)
  • Friends: Haida, Fenneko
  • Rivalry-turned-friendship: Hello Kitty
  • Loves: Pizza, strawberry-drizzled milkshake ice cream, death metal karaoke, typing, reading newspapers

Fenneko

Fenneko

The Energetic Engineer

Fenneko joins the cast in Season 2, and the picture above is her prequel look — the outfit she was wearing the very first time we see her, not her main school outfit. She and Haida went to Aggretkotsu Academy alongside Retsuko, and when Retsuko left for Sanrio High, the two of them were left behind feeling lonely, so Fenneko flew them both in on her own helicopter, the Yellow Capery, to track her down. Underneath her energetic exterior is an amazing heart, and she will always protect Retsuko no matter what. She's passionate about engineering, but just as obsessed with fashion and social media, and she loves being energetic more than almost anything. She has a crush on Pandapple that she eventually works up the courage to express. Her favorite place to unwind is Berry Swirl Market, where she shops until her bags are overflowing, and her favorite subject is Shimmery Exploration. She's rarely seen without her phone, and her go-to treat is a vanilla, cherry, and strawberry ice cream sundae.

  • Loves: Engineering, fashion, social media, shopping at Berry Swirl Market, her phone, vanilla/cherry/strawberry ice cream sundaes
