Born on September 9, Hikage developed emotional detachment early, molded by orphanage life where peers taunted her impassive face. At eight, she fled to a gang under Hinata’s leadership—a surrogate mother who nurtured her stoicism. Hinata’s demise in a clash spurred Hikage to enshrine her leader’s knife, a token of their bond and the catalyst for her first visible emotion: a "drip in her heart, rain inside." Hebijo Academy’s Elite Class recruited her for her criminal past, positioning her as Haruka’s immediate successor. She wields twin knives concealed in gauntlets, striking with serpentine agility. The emotionless shell fractures subtly during *Bon Appétit!*'s cooking competition, where adopting a festival vendor persona—crafting puns to lure patrons—sparks contemplation of existence beyond the shinobi path, though her exterior remains unchanged. Complex ties define her interactions: a cautious dance with Haruka, dodging her experimental drug trials, contrasts with dry-witted exchanges and silent alliances with Daidōji and Yagyū. A Kansai lilt and inked tales of a hardened past set her apart. Beyond her core tale, she surfaces in *Kandagawa Jet Girls* as DLC, stretching her reach. A sporadic restaurant gig hints at mundane counterpoints to shinobi shadows. Her name, "sunshine" veiled "among shadows," mirrors her duality—forged in loss, balancing solitude with ephemeral bonds.
