Hajime Aoyagi, a former Sohoku High School bicycle racing club vice captain, evolved from a reticent first-year into a strategic leader by his final year. Initially introverted, he communicated minimally yet harbored profound concern for teammates like Junta Teshima, Jin Tadokoro, Shoukichi Naruko, and Kimitaka Koga. His gradual shift toward camaraderie culminated in mentoring first-year Issa Kaburagi through written cycling strategies, blending his quiet nature with mentorship. Physically, his appearance transformed from short brown hair obscuring one eye to shoulder-length dark blond locks. Media depictions inconsistently rendered his eyes as gold, blue, or brown, while his wardrobe frequently sported exclamation-mark motifs. Aoyagi’s cycling ethos shifted under Teshima’s influence, embracing teamwork over solitary training. His resilience shone through feats like dragging Junta from the pack’s rear and propelling Sohoku forward at the Inter High despite a knee injury. His tactical innovations included the "Supersonic Oxygen Human Bullet Aoyagi Train," a sprint fueled by rapid oxygen intake, and the "Bambi Style," concentrating thigh power for high-cadence cornering. The "Fake Launch" tactic masked teammates’ sprinting vulnerabilities, showcasing adaptability offset by stamina limitations. Early achievements featured Chiba Prefecture rookie race victories and a third-place finish in the Bay Coast Criterium Race. After initial Inter High exclusions, rigorous training camps secured his third-year team spot. Beyond cycling, he frequented art galleries, savored plum rice balls and cabbage, played DS games, and sketched landscapes with notable skill. Aoyagi’s narrative arc centered on selfless domestique duties, epitomized during the 42nd Inter High when he exhausted his strength to reunite Sohoku with Hakone’s frontrunners before withdrawing. His journey—from withdrawn cyclist to a linchpin of teamwork—embodied themes of perseverance and collective triumph.
