Meet the characters from Vivy: Fluorite Eye’s Song

Vivy

Okay, Vivy is the absolute heart-melter of the show — bright, earnest, and weirdly stubborn about doing things the “right” way (which for her usually means singing until people stop being awful). She’s a singer-AI who slowly becomes this fierce, almost clumsy protector, like “I will save the world but also perform three encore numbers first” energy. There’s this adorable mix of robotic logic and suddenly very human panic (one minute perfectly precise, the next she’s melodramatic and teary — probably over-singing, honestly). She also has these tiny odd habits, like fiddling with a hairclip she maybe never owned, and sometimes she contradicts herself about being “just a performer” — clearly not.

Matsumoto

Matsumoto is that dry, mission-first AI buddy who’s secretly low-key sentimental but will never, ever admit it unless you catch him off-guard at 3 a.m. He shows up as the prickly foil to Vivy — hyper-efficient, sarcastic, slightly condescending, but also stubbornly loyal in the way only an algorithm can be. He’s got this weird fondness for practicality (and umbrellas? maybe) and a habit of making grim predictions and then softening them with a terrible joke. Also, he’s oddly obsessed with efficiency diagrams and small pastries — don’t ask how those go together, it’s a mood.

Yugo Kakitani

Yugo is brilliant, kind-ish, and slowly unravels into this tragic, desperate figure who thinks the end justifies every terrible shortcut (you can almost feel the heartbreak). He starts with idealistic tech hopes and becomes obsessed with changing fate, which is both compelling and horrifying — like watching someone rewrite their favorite song until it’s unrecognizable. Charming? Sometimes. Dangerous? Very. Oh and fun detail: he collects paper cranes and also has a playlist of comforting lullabies he never listens to when he should.

Elizabeth

Elizabeth is this cool, ambiguous presence — part corporate power, part enigmatic mastermind, and part someone who definitely reads a lot of old romances for reasons that might be strategic. She’s polished, composed, and often chillingly calm, but every once in a while she slips a knowing smile that makes you question everything (in a good way). She’s the kind of character who can give a three-sentence speech and somehow make it sound like a prophecy. Also, she drinks tea from mismatched mugs and is either very patient or secretly chaotic, depending on the scene.

Professor Matsumoto

Professor Matsumoto (yes, confusing — two Matsumotos, deal with it) is the rumpled genius-professor type who clearly loves his work more than sleep or social cues, and honestly? relatable. He’s equal parts mentor and morally grey tinkerer, always rambling about theories while absentmindedly feeding a stray robot part he calls “Gus” (probably shouldn’t be allowed). He’s full of regrets and brilliant ideas, and there’s this lovable scatterbrain energy — except when he’s terrifyingly focused, which is when you should probably listen. Little quirk: he labels everything in his office with stickers, including people’s names once, which was awkward.
