Yutaka Asahi instructs aspiring jockeys at the JRA Horse Racing School, personally guiding students including Yu Arimura. His charcoal grey hair falls to his neck, framing hazel eyes and a distinct goatee. He consistently dons a black hat, a white dress shirt layered over a long-sleeved grey shirt, a black belt, pants, and boots. Elusive in nature, he communicates with a unique tone while maintaining a professional instructional demeanor. He shares a bond with his twin brother, Takeshi Asahi—an adult monk with facial hair—and engages primarily in professional relationships with racing school students like Yu Arimura.
