Hikage is a young female member of Special Fire Force Company 7 and the twin sister of Hinata, both serving under Captain Benimaru Shinmon in Asakusa. Her black hair forms a bubble at the back and sweeps left across her face, contrasting Hinata’s right-parted style. She dons a black kimono with flame-patterned sleeves and a blue waist stripe, denoting her Company 7 allegiance. Jolly and mischievous by nature, Hikage frequently uses vulgar language—traits she attributes to Benimaru, though he denies influencing her. Despite her innocent look, she relishes confronting those she deems "bad people" and shares an unbreakable bond with Hinata; their deep mutual understanding foils impostors and prevents arguments. Hikage avoids keeping secrets from Hinata to avoid angering her and possesses an intense fondness for sweets, even bargaining her clothing or silence for candy. As a Third Generation pyrokinetic, Hikage generates and manipulates flames, cloaking herself in a fiery fox-like aura that amplifies her strength and agility to overpower adults effortlessly. Her combat style mirrors Hinata’s, allowing seamless coordination in battle. During the Asakusa arc, White-Clad members kidnapped Hikage and impersonated her to infiltrate Company 7. She surrendered her kimono willingly and hid this from Hinata in exchange for sweets. Dissatisfied with the candy amount, she attacked her captors and escaped. Reuniting with Hinata, the twins joyfully incinerated the kidnappers after branding them "bad people." In the Great Cataclysm arc, Hikage perished during the catastrophe. Shinra Kusakabe later reversed the cataclysm by manipulating time and restructuring reality, reviving her.
