A masked stranger emerges as the protagonist's key mentor after a severe racing crash leaves him hospitalized. Concealing his face with a ski mask, this unnamed figure offers a second chance at racing, claiming to be a world-famous driver and referencing the name "Nick" (a character inspired by Formula One champion Niki Lauda).

He secures the protagonist's entry into the Katori Motors racing team, providing access to prototype vehicles and professional competition. His mentorship involves actively monitoring progress and decisive intervention during crises, including physically confronting the protagonist to prevent resignation after setbacks. His guidance is instrumental for the protagonist's participation in events like the Japanese Alpine Road Rally and the construction of a custom race car from scrap materials.

A significant revelation later identifies the masked man as the protagonist's father, who disappeared during a military training flight. This paternal bond explains his deep involvement. He oversees critical milestones, including observing the test drive of the protagonist's self-built car on Mount Fuji.

His influence propels the protagonist's journey from discouraged crash survivor to competitor in elite events like the Monte Carlo Road Rally. While his identity as the father is revealed, his full name, specific history beyond the military disappearance, and face beneath the mask remain concealed.
