Kaname Hiiragi, the second eldest among six non-blood-related sisters in the Hiiragi household, carries herself with a quiet reserve layered beneath a multifaceted persona. Her sharp black hair—spiky bangs contrasting straight lengths—frames pale features accentuated by vivid crimson eyes, while her tall, slender frame (172 cm, 88-58-87 cm) commands silent attention. Publicly, she thrives as the "Icy Lawyer," a title earned through unflappable courtroom poise and a reputation for cool detachment. Privately, however, career pressures gnaw at her composure, fueling secret yearnings for escape into prolonged solitude.

Central to her narrative is the fractured bond with Kuuya Hiiragi, the family’s adopted brother and her first love. Their strained dynamic reignites when he returns after years of forced separation—a consequence of their father’s intervention in their childhood closeness. A single volatile encounter between them, charged with confrontation and intimacy, sparks Kuuya’s resolve to reinvent himself, mirroring Kaname’s tsundere duality of sharp-edged assertiveness veiling fragile emotional undercurrents.

Within the family’s chaotic orbit, she juggles legal obligations with sibling duties, often retreating into risky stress-relief habits like late-night drives paired with alcohol. Though naturally guarded, she engages in the household’s eccentric rituals, swapping tailored suits for school uniforms, traditional kimonos, or athletic bloomers—garments that clash pointedly with her polished professional veneer.

Her past, shadowed by Kuuya’s abrupt removal from the family during their youth, fuels present tensions. His homecoming unravels half-buried grievances, manifesting in her conflicted actions—a dance of sharp words and concealed care. Kaname meticulously upholds an illusion of control, her true emotions locked behind practiced indifference as she navigates the crosscurrents of duty, desire, and unresolved familial scars.
