Okuyasu Nijimura begins as a violent antagonist, motivated by unwavering loyalty to his brother Keicho, who seeks to euthanize their father—a mutated husk corrupted by Dio’s flesh bud. Following Keicho’s demise, Okuyasu aligns with Josuke Higashikata and Koichi Hirose, clashing with Morioh’s malevolent Stand users. His Stand, The Hand, wields space-erasing power, though its potential is tempered by Okuyasu’s blunt tactics and self-deprecating view of his intellect. Through harrowing battles and split-second choices, he hones his instincts, bridging raw strength with budding strategy. Okuyasu’s past is scarred by poverty, parental abuse, and his mother’s death. His father’s grotesque transformation pushed Keicho to exploit Stand arrows, drafting Okuyasu into a desperate crusade. This forged a reliance on his brother’s commands, leaving him adrift after Keicho’s death. Beneath his abrasive demeanor lies fierce devotion, evident when he pleads with Keicho to spare their father and later cares for the mutated figure alone. His loyalty extends to allies, as seen when he charges to aid Koichi against Rohan Kishibe, only to be ensnared by Heaven’s Door—a Stand that manipulates him into a near-fatal act. Though this clash strains his rapport with Rohan, it underscores his readiness to risk himself for others. Pivotal growth emerges during Yoshikage Kira’s assault: gravely wounded, Okuyasu defies death, spurred by a vision of Keicho urging autonomy. This resolve fuels his critical role in Kira’s defeat. His personality melds brashness with childlike quirks—complaining about singlehood, nitpicking expenses—yet his moral core stays unshaken. The Hand’s spatial manipulation sporadically reveals ingenuity, like warping terrain or outmaneuvering foes, balancing Okuyasu’s impulsivity with flashes of tactical clarity. His arc traces a path from dependence to self-trust, anchored by loyalty and a humor-edged heart.
