A monstrously talented cyclist who exercises absolute control over the team. He values only the result of being 'number one' over process or sportsmanship. He treats even his teammates as tools or parts for victory, ruthlessly discarding them if they lose their utility. He intimidates those around him with behavior and speech that defy common sense, but beneath it all lies a terrifying obsession with winning. 1st Year.

Initially, he rebelled against Midosuji's dictatorship and inhumane methods. However, realizing that Midosuji's pure obsession with victory and monstrous skill are genuine, he sets aside his pride for the sake of the team's success. He voluntarily becomes Midosuji's 'right hand' and 'steed.' Throughout the Inter-High, he silently endures Midosuji's vitriol and verbal abuse, perfectly fulfilling his role as a windbreaker so Midosuji can sprint at the final finish line. He fulfills his responsibility as captain until the very moment he collapses by the roadside from exhaustion, pushing Midosuji forward. 3rd Year Captain.

Fascinated by the ace Midosuji's overwhelming skill, he mimics his unique eccentricities and speech patterns. He often acts like a sycophant, monitoring or creating friction among teammates to get on Midosuji's good side. While he appears absolutely obedient on the surface, he secretly harbors the ambition that "if Midosuji falls, I will become the ace of this team." He has a strong comedic side, often bluffing beyond his actual skill level and provoking Sohoku or Hakone Academy riders only to have it backfire. 2nd Year.
