Kyōhei Misumi, a second-year student at Noukin High School, carries a history of junior high delinquency marked by frequent brawls. Transitioning to a calmer demeanor upon entering high school, he was pressured into joining the kabaddi club by Kei Iura, who exploited his turbulent past. Over one year and one month of involvement, he adapted to the sport’s discipline, balancing his aggressive instincts with teamwork.

Standing 178 cm tall with a muscular 80 kg frame, he sports scruffy orange hair and green eyes (alternately noted as brown hair and petrol-colored eyes). His red Noukin Kabaddi uniform, emblazoned with the number 3, underscores his athletic role. Born March 9 under Pisces with blood type B, his zodiac and biological traits hint at a complex personality.

Once a volatile delinquent, Kyōhei now channels his physical prowess and aggression into strategic kabaddi plays, evolving from isolation to collaboration. Key victories showcase his growing self-worth, countering earlier insecurities. His name—combining “capital city” and “peaceful” in “Kyōhei,” with “water” and “clear” in “Misumi”—mirrors his journey from chaos to clarity.

Interactions with teammates like Shinji Date, who share histories of abandoned athletic ambitions, deepen his narrative of redemption. Their mutual struggles emphasize themes of purpose and resilience, anchoring Kyōhei’s evolution within a broader exploration of identity and belonging.
