Yuya Fubuki serves as the protagonist of the original "Circuit no Ohkami" manga serialized in Weekly Shōnen Jump from 1975 to 1979. This young racer pursues a singular ambition: becoming the Formula One World Champion. His journey through professional racing's competitive world forms the core of the franchise, charting his challenges, rivalries, and growth within motorsports' high-stakes environment.

As an early dedicated racing protagonist in shōnen manga, his character established a precedent for future genre series. The sequel, "Circuit no Ōkami II: Modena no Tsurugi," shifts focus to a new protagonist, Ken Ferrari. Yuya Fubuki's direct involvement or development in that storyline, including its OVA adaptation, remains absent. His background, development, and driving dream of F1 supremacy are firmly rooted in the original manga series.
