In the past, he was an exceptionally talented professional Keijo player, widely recognized for his strategic prowess and his most famous technique, the "Vacuum Butt Cannon." His promising career was cut short prematurely by a severe hip injury, an event that led him to dedicate himself to training the next generation of players. As an instructor, he is distinguished by his eccentric yet highly effective training methods, guiding the protagonist Nozomi Kaminashi and her peers toward professional careers. His prestige in the world of Keijo stems from both his past achievements and his reputation as one of the country's top trainers, capable of transforming raw students into high-level competitive athletes.
