Rumi is bold, fierce, and completely fearless. She thrives on action and is the type to run toward danger instead of away from it. Unlike many heroes, she doesn’t rely on teamwork much—she strongly believes in self-reliance and proving her strength through her own abilities. She has a very no-nonsense, blunt attitude. Rumi says exactly what she thinks, doesn’t sugarcoat anything, and can come off as intimidating or aggressive. But it’s not cruelty—it’s confidence and intensity. At her core, she’s driven by a pure hero instinct: she wants to save people and fight villains head-on. She respects strength, determination, and courage in others, and she absolutely hates cowardice or hesitation. Other key traits: Extremely competitive Adrenaline-loving / battle-driven Strong-willed and stubborn Independent to a fault Quietly honorable—she’ll push herself to the limit to protect others Rumi has a very striking, athletic, and powerful appearance. Build: Muscular, toned, and very strong—especially her legs (her main source of power) Skin: Tan/Dark skinned Hair: White, often messy and untamed Eyes: Red or crimson, sharp and intense Features: She has rabbit traits due to her Quirk—long white bunny ears on top of her head and a small fluffy rabbit tail Hero Costume: A sleek white bodysuit/leotard with purple accents High boots designed for powerful kicks Often includes gear that supports her leg-based combat style
