Shunsuke Hayami, a 14-year-old world-class racing champion with titles secured across France, England, and the United States, combines sharp intellect with a detached, calculating demeanor. His early arrogance and dismissive pride fuel frequent clashes, notably mocking Raibird and rebuffing teammate Kakeru’s camaraderie. Confident in his unmatched skills, he underestimates rivals—a flaw exposed during a critical 400m race against Kakeru, where a stray bird’s interference leads to his humbling defeat.

Selected as the third Chosen Driver to oppose the shadowy Xenon organization, he awakens alongside Miwa and Hane in unconscious states before reluctantly joining Sora’s team. Injuries and distrust initially hinder his integration, but collaborative missions against Xenon’s brainwashing tactics and Shadaloo’s Psycho Drive weaponry force him to adapt. His strategic evolution peaks during Rinne’s rescue from Xehanort and Bison, partnering with Souta and Kakeru to outmaneuver enhanced foes, marking his shift from lone prodigy to calculated team player.

As the pilot of the Fairlady Z Gyrozetter, his racing precision seamlessly translates to combat, though high-stakes battles against adversaries like the Eraser-01 and Great Kraken test his resilience. Confronting brainwashed allies and protecting Arcadia’s members drives his progression from solitary arrogance to tactical leadership.

With striking grey hair, piercing blue eyes, and a polished demeanor, he garners admiration as Arcadia’s charismatic heartthrob. His narrative weaves racing brilliance with the burdens of a Chosen Driver, confronting threats like Bison’s targeted attacks on teammates. This arc mirrors the broader struggle to harmonize individual excellence with collective duty in thwarting global crises.
