Reina is a short girl with long silver hair and deep blue eyes who tends to have a blank expression on her face—even when she's laughing or crying. She can smile and get genuinely cheerful, though it mostly happens around Shouta Raidou, the boy who picked up her eraser one day in class. That small moment sparked her interest in him.
She's quiet and timid, with a real problem reading social cues. With people she doesn't know, she gets so shy her voice practically disappears. But then she'll swing the other way and get overly friendly with someone she just met, acting way too familiar without realizing it. That unpredictability, combined with her deadpan face, got her isolated pretty badly in the past, which left her genuinely afraid of getting close to anyone. Now she's incredibly grateful to anyone who accepts her weird behavior—her friends, her family—and feels like she owes them something. She'll cook for them, help them study, whatever she can do to pay back the kindness.
Because of how badly she misreads social distance, Reina's constantly second-guessing how her friends actually see her. She worries she's being a burden, that her issues are too much. Still, when her friends need her, she doesn't hesitate to step up. She's protective of her friendships and makes a point of showing how much she appreciates them. She's said she wants her high school friend group to stay close even after graduation.
You'll usually see her in her school uniform: dark blue button-up over a white shirt, navy skirt, long black tights, and brown loafers.
