Hinata Aoi, elder twin brother of Yuta Aoi and leader of the idol unit 2wink under COSMIC PRODUCTION, radiates a mischievous charm. A playful trickster, he swaps places with Yuta during class and infuses performances with high-energy vocals tempered by warmth. Though outwardly cheerful, he hides a shy, impulsive streak, fiercely prioritizing Yuta’s happiness even when it strains their bond. Their relationship anchors his identity, yet he quietly navigates their diverging perspectives to sustain their partnership. Hinata’s vibrant orange hair, parted at the center, frames green eyes and features two dark pink clips on the left. His school uniform leans casual—shirt untucked, blazer unbuttoned—paired with hot pink headphones. Onstage, he dazzles in sleeveless vests and harem pants blending hot pink, aqua blue, white, black, and yellow, accessorized with wristbands and nail polish. Off-duty, layered jackets, zippered shirts, and color-blocked pants mirror his lively yet cohesive aesthetic. Behind his exuberance, Hinata secretly takes on extra work to fund their idol path, stemming from a determination to position Yuta for success. This covert hustle strains their connection, as he masks his vulnerabilities behind a united front. Though he champions twin-centric performance concepts as 2wink’s leader, clashes emerge over their unit’s direction. Despite his sociable facade, he keeps even Yuta at a subtle distance, guarding his inner struggles. His hiragana-written name evokes sunflowers and the sun-moon duality, casting him as Yuta’s radiant counterpart. He shares a home with his father, twin, and two cats. A lover of sweets who tolerates spice, Hinata shines in interactions with children. His autograph bears a triangle motif echoing 2wink’s branding. Narrative arcs trace his journey to harmonize leadership, brotherhood, and personal growth. As Yuta questions their unit’s path, Hinata confronts the tension between public unity and private fractures, seeking resolution through shared understanding beyond the stage. His evolution hinges on balancing vulnerability with responsibility, redefining partnership while preserving their inseparable identity.
