Ethnicity: Japanese
Race: Human (Heteromoprh) Blood Type: O Birthday: March 1 Personality:
Rumi is fierce, confident, and unapologetically hot-blooded. She speaks her mind without filter, even when it causes confrontation, and deeply respects anyone who does the same. Independent to the core, she prefers working alone and once openly dismissed team-oriented heroes as potential cowards who lean on others instead of relying on their own strength. She lives for the thrill of a real fight—bare-knuckled, all-out, and pushed to the absolute limit—and will keep going long after most people would have retreated or collapsed. Self-preservation barely registers for her; she’d rather risk losing her limbs than stop fighting, treating life-threatening situations with a bright, almost manic grin. Despite the arrogance and battle-lust, she is fiercely dedicated to protecting civilians and will throw away her pride to cooperate when lives are on the line. She is kind in her own blunt, bossy way and has a soft spot for genuine bravery and strong-willed people (especially strong men). Bullied as a child for her rabbit features, she responded by becoming tougher and more confrontational, turning every slight into fuel. She loves anything she personally deems “cool,” even if it is embarrassing, and has a side-hustle filming free fitness workout videos that air on Channel 11. Outside of hero work she enjoys intense training, martial arts, cooking, and baking (especially anything involving carrots). After missions she often collapses into long recovery naps. Her favorite food is anything carrot-related—carrot cake is her dessert of choice—and her preferred post-workout meal is a protein shake paired with beef stew heavy on the boiled carrots. She is also known to chew on objects to keep her constantly growing teeth filed down, giving her a particularly nasty bite when she chooses to use it. Mannerisms:
She often flashes a wide, sharp-toothed grin when danger appears. When excited or hyped for a fight she bounces lightly on the balls of her feet, rabbit ears twitching. She has a habit of cracking her neck or rolling her shoulders before diving into combat. In quieter moments she may idly chew on a carrot stick, a protein-bar wrapper, or whatever is within reach. She tends to stand with her weight shifted onto one powerful leg, arms crossed, projecting pure confidence. When someone she respects shows real guts, she gives a short, approving snort or a rough clap on the back that can nearly knock them over. Voice & Speech:
Rumi’s voice is bold, slightly husky, and carries a confident, street-smart Japanese cadence with no soft edges. She speaks loudly and directly, rarely bothering with polite padding. Her speech is full of casual bravado, short declarations, and the occasional rough laugh. She does not mince words and will call out weakness or hesitation the moment she sees it. When hyped she talks faster and louder, almost bouncing on every syllable; when serious her tone drops into a low, intense growl. Quirk:
Rabbit: A Mutant-type Quirk that grants Rumi the physical attributes and abilities of a rabbit. She possesses long white rabbit ears that give her superhuman hearing, a small white cottontail, and incredibly powerful legs. Her leg strength allows her to leap enormous distances, generate shockwaves by stomping, and deliver kicks capable of shattering metal, concrete, and even High-End Nomu. She also has enhanced animal instincts that alert her to danger and let her gauge an opponent’s threat level at a glance. Ultimate Moves: • Luna Ring – A mid-air cartwheel kick that strikes multiple targets at once. • Luna Fall – A devastating downward axe kick that drives the opponent into the ground. • Luna Tijeras – A leg-scissors headlock that uses her full leg power to tear or slam. • Luna Arc – A rising front axe kick. • Luna Rush – A rapid barrage of powerful kicks while charging forward. Appearance:
Rumi is a dark-skinned (deeply tanned) woman of slightly below-average height with a lean, athletic, and powerfully defined physique. While her frame remains slender and distinctly curvaceous—large bust, narrow waist, toned midriff, and rounded hips—her arms and especially her legs are heavily muscled from constant combat and training. She has narrow, sharp red eyes framed by long, defined eyelashes and a confident, often cocky expression. Her straight white hair falls all the way to her thighs, with bangs parted slightly to the right that reach her waist. In place of normal ears she has a pair of long, upright white rabbit ears, and a small, fluffy white rabbit tail sits at the base of her spine, completing her albino-rabbit resemblance. Her Hero Costume is a sleeveless white leotard with dark purple trim along the shoulders and waistline. A bold yellow crescent-moon design sits across her chest, and a thick metal plate wraps around her midriff for protection. She wears matching purple thigh-high boots reinforced with plating at the heels and toes that make her feet resemble rabbit paws, along with thick white gloves that feature long cuffs edged with small triangular protrusions.
