Akira Midōsuji reigns as the third-year captain and undisputed ace of Kyoto Fushimi High School's bicycle racing club, a position seized during his first year by defeating the previous ace in a decisive race. The former captain then yielded leadership to Midōsuji, acknowledging his superior skill and consistent victories. He commands the club dictatorially, demanding absolute control over team strategy and member assignments. Physically, Midōsuji possesses a tall, slender frame featuring remarkably long, flexible limbs and wide shoulders. His appearance transforms significantly throughout high school, particularly his hairstyle: shifting from medium-length to a buzzcut, then a mohawk, spiked hair resembling a mace, and finally a bowl-cut. Distinctive features include an extremely long, frequently protruding tongue and unsettling bodily contortions producing disturbing sound effects in animation. His eyesight measures an exceptional 20/10. Midōsuji exhibits a severe, eccentric, and manipulative personality. He deploys psychological warfare to destabilize opponents, ruthlessly invoking past traumas, weaknesses, or fears mid-race. He dismisses others, including teammates, as "small fry" or "zaku" (insignificant). Expressions of camaraderie or emotional passion disgust him, often labeled "gross." He treats teammates as expendable pawns, abandoning them during climbs when deemed useless. He harbors specific animosity toward Shunsuke Imaizumi, stemming from a past tournament where Midōsuji's underhanded tactics cost Imaizumi victory; tormenting Imaizumi brings him particular enjoyment. An intense pride in his square teeth defines him, instilled by his late mother's belief that athletes require beautiful teeth. He deeply revered her, and this devotion initially fueled a mentality of racing every event as if his last. This approach eventually caused burnout, forcing him to drop out 3km from a finish. By his second year, he developed an obsession with turning situations into wagers and experimented sadistically with transforming his racing style. As an all-rounder cyclist, Midōsuji excels in climbing, sprinting, and tactics. His intellect is paramount, enabling intricate, multi-phase strategies with contingencies for environmental variables and opponent strengths, meticulously researched beforehand. His racing leverages unique physiology: the "dancing technique" involves leaning his torso perilously low over the handlebars to minimize wind resistance. His modified De Rosa bicycle features an elevated saddle and extended handlebars to accommodate this position and utilize his long limbs. His signature "real form" activates when rolling up jersey sleeves and shorts legs, accompanied by full neck extension and muscular power release, drastically boosting speed to close large time gaps, especially on descents. This form incorporates the "Full-Throttle Dive Banks" cornering technique – leaning the bike dangerously low at high speeds. His "Morphed sprint form," the "Grasshopper/Locust form," positions head and back parallel to the ground with elbows thrust backward. By second year, he adapted this form for climbs, using strapped thigh muscles released only for final sprints, aiding wet-weather control. He also employs the "bike throw" technique, thrusting arms forward at the finish line for milliseconds' advantage, demonstrated in his victory against Hayato Shinkai. Midōsuji's backstory includes an early fascination with insects and pre-high school racing victories: Arashiyama Hill Climb, the 15th Fushimi Road Race, and the 11th Chiba Cycling Road Race representing Tachibana. Interactions with Sakamichi Onoda in Grande Road suggest complexities beyond his antagonistic facade. His family name's official pronunciation is "Midousuzi" (TMS Entertainment/merchandise), commonly transliterated as "Midousuji" in English. Hobbies include an interest in bicycles (favoring De Rosa) and watching the anime "Love Hime," the same series featured on Onoda's bike stickers (his opinion unknown). Favorite foods are eel, tofu, and eggs; he enjoys Western music, British music, and children's songs.
