Gozumaru commands as the young head of the Gyūki Clan, residing among the Nura Clan’s ranks as a contender for future leadership. His appearance mirrors Gyūki’s influence, with dark brown hair swept into a tie at the nape, deliberately veiling the left half of his face—a reversal of his predecessor’s style. When loosened, his hair frames a deceptively feminine bob, a trait he hides with prickly reluctance. Exuding icy composure laced with calculated cruelty, he fiercely champions his clan’s supremacy over the Nura main house, driven by arrogant confidence in his combat prowess and a thirst to test it against rivals like Ryūji and Mamiru. Loyalty to Gyūki anchors his every move, pushing him to orchestrate conspiracies against Rikuo Nura. During the clan’s rebellion, he isolates Rikuo and Tsurara to eliminate her, only to fall to Rikuo’s untransformed strength. Following Gyūki’s pardon, he and Mezumaru endure forced residence at the Nura estate. In the Shikoku conflict, he spearheads reconnaissance against the Shikoku Hachijūhakki Yakō, deploying razor-string tracking and clashing with adversaries like Gangi Kozō before Tamazuki’s assault leaves him wounded, requiring rescue by the Sanba Garasu. He wields a katana and manipulates razor-edged strings, though his precision falters compared to Mezumaru’s mastery. His signature Gozu Shadow Claw summons chitinous pincers from his back to strike foes, while a hypnotic chant bends wills—a tactic used on Shima, Kiyotsugu, and Gangi Kozō. Relationships reveal contradictions: he locks horns with Mezumaru in fiery disputes yet shields a fiercely protective bond, harbors grudging respect for Rikuo beneath disdain, and nurses ambiguous sentiments toward Tsurara, speculated by peers to mask a concealed infatuation. Standing 162 cm with a lean 58 kg frame, his personal quirks include a June 28 birthday and a disdain for sweets. Paired with Mezumaru, their combined names evoke the ox-headed and horse-faced guardians of Chinese myth. His possessions span an ancestral Japanese sword and dried ginkgo, while his piercing white pupils mark his gaze. Across narratives, he embodies unwavering loyalty and razor-sharp cunning, threading a volatile path between rivalry and uneasy collaboration within the Nura Clan’s intricate hierarchy.
