Junpei Hyūga captains Seirin High’s basketball team as its sharp-shooting guard, reluctantly embracing leadership before maturing into a steadfast pillar of the team. His short dark hair, gray eyes, and glasses contrast his first-year bleached blond style—a remnant of teenage rebellion after nearly abandoning basketball post-junior high losses. Teppei Kiyoshi’s intervention reignites his drive, steering him to Seirin and rekindling his competitive fire. Renowned for clutch three-pointers, Hyūga shifts from mimicking Ray Allen to mastering Reo Mibuchi’s "Earth" technique. Under Kagetora Aida’s guidance, he devises the Barrier Jumper, a step-back mid-dribble maneuver crucial in high-stakes games. Opponents eventually decode its timing, yet his cold focus and combative intensity during critical plays cement his reputation as a pressure performer. Raised in a family barbershop, he hones haircutting skills alongside academic prowess in Japanese history. His downtime features collecting warrior figurines, crafting battle dioramas, and binge-watching historical dramas. He avoids ghost stories, favors cats, and endures coach Riko Aida’s disastrous cooking—subtly masking his unspoken affection for her. Initially clashing with Kiyoshi, Hyūga evolves to revere him as a mentor, while fostering camaraderie with teammate Izuki Shun. Leadership trials harden his resolve, anchoring his belief that "Perseverance is power." Key growth arcs see him conquering past insecurities, perfecting the Barrier Jumper in winter training, and dissecting rivals’ strategies mid-game, such as dismantling Reo Mibuchi’s plays. Though prone to technical fouls and ranking lowest in skill drills among second-years, Hyūga’s shooting accuracy remains elite. Quirks like attempting hot-spring voyeurism contrast his role as Seirin’s emotional anchor, rallying teammates under duress and stabilizing morale when stakes soar.
