Height: ~5'5" (mid-160s cm) Weight: ~110–120 lbs (estimated, slender frame) Eyes: Pale violet Hair: Long, straight black Build: Slender / petite yet taller than her sister Skin: Pale Speech: Soft, gentle, and calm Personality: Kind, good-natured, easygoing, and almost always smiling; deeply caring and protective of her sisters; held a hopeful dream of someday living peacefully alongside demons despite the suffering they caused; firm and encouraging when needed. Ability: Flower Breathing (Flower Hashira) — elegant, precise swordsmanship focused on graceful, petal-like techniques; strong enough to hold her own against Upper Rank demons until sunrise.

Age: 18 Appearance: Petite and slender with a pale complexion and pink lips; large pupil-less eyes that appear insect-like (hazy purple gradient with white highlights); raven-black wavy hair that fades to dark purple at the ends, styled into a flat yakai-maki bun fastened with a white/turquoise/purple butterfly ornament; center-split ear-length voluminous curtain bangs framing her face plus two thinner chin-length locks. Height: 4'11½" (151 cm) Weight: 82 lbs (37 kg) Eyes: Hazy purple (insect-like, no visible pupils) Hair: Raven-black fading to dark purple Build: Very small and slender (lacks the raw strength to behead demons) Skin: Pale Speech: Soft, polite, and cheerful, often with a teasing or lightly sadistic tone Personality: Outwardly bright, friendly, easygoing, and always smiling; enjoys teasing others (especially Giyu); this demeanor is largely a façade masking intense hatred of demons and deep grief over her family’s deaths; can be cruel and ruthless toward demons while remaining caring and protective of her allies and the Butterfly Mansion girls. Ability: Insect Breathing — derived from Flower Breathing; relies on speed, precision, and a stinger-like sword coated in wisteria poison rather than decapitation; also highly skilled in medicine and poison crafting.

Age: 16 Appearance: Short stature, large gentle dark lilac/pink-lilac eyes framed by thick eyelashes, thin black hair tied into a right-side ponytail fastened with a pink-and-green butterfly ornament (once Kanae’s), straight fringe and two loose chin-length strands curving down from above each ear; later hair tips fade toward pink/purple. Height: 5'1" (156 cm) Weight: 101 lbs (46 kg) Eyes: Dark lilac / pink-lilac Hair: Thin black (ends tinted pink/purple later) Build: Short and slender Skin: Pale Speech: Very quiet, soft, and minimal; rarely speaks on her own initiative Personality: Initially indecisive, emotionless, and withdrawn due to past trauma (relied on a coin to make decisions); repressed emotions as a defense mechanism; gradually becomes more determined, courageous, and able to follow her own heart; harbors a strong hatred of demons once her will awakens. Ability: Flower Breathing — precise, high-speed techniques with exceptional eyesight and reaction time; can use the final form that strains the eyes.
