Yoma Hashimoto, a young Japanese model recognized for his striking light hair with dark streaks and compact, camera-friendly features, transitions from an athletic frame to a formidable, sculpted physique marked by wing-shaped muscle formations on his trapezius and ankles. These anatomical distortions, symbolic of his bond with Hermes, emerge after he commits to an intensive training regimen at the Morioh Grand Hotel gym. There, his rivalry with Rohan Kishibe ignites through competitive treadmill duels. Initially driven by disciplined ambition, Yoma’s psyche warps into a narcissistic obsession with bodily perfection. He enforces a merciless routine: protein-only meals, rigid sleep cycles, and grueling workouts, erupting into violence when confronted. His fixation escalates to embezzling from his girlfriend Mika, converting her apartment into a bouldering maze, and slaughtering Mika, a deliveryman, and a gym patron—casualties he dismisses as hindrances to his ascension. As Hermes’ chosen vessel, Yoma wields preternatural prowess: sprinting backward at 20 km/h, hurling 20 kg weights with ease, and enduring lethal impacts. His muscles amplify strength and stamina, while his perception pierces supernatural forces like Rohan’s Heaven’s Door, visualized as floating manuscript pages. Adaptations underscore his divine link through an ethereal aura mirroring classical Hermes imagery, hinting at either Stand affinity or godly possession. In their climactic duel, Yoma sabotages Rohan’s fingers to force a “balanced” treadmill race. Seizing the victory remote, he triggers his own defeat—deactivating Rohan’s machine launches him backward through a window. His survival hangs unresolved; Rohan theorizes either inhuman athleticism or divine mercy spared him, with the creator acknowledging potential reappearances. Beyond modeling, Yoma’s brief acting stint connects him to prominent performers, though his tale centers on his physical and moral unraveling. Adaptations enrich his Hermetic ties visually while preserving his core descent into obsession.
