A legendary karate master and founder of the Hokushin School, he's basically obsessed with testing himself against the strongest fighters around. He's the kind of guy who'll straight-up call himself "The Strongest of all"—and given his reputation, not many people argue. His whole thing is seeking out worthy opponents, which is why he organized that tournament with Tatsumi, dangling a shot at fighting him as the prize. The whole setup screams someone who needs constant challenge to feel alive.
The character was inspired by the real-world legend Mas Oyama, the founder of Kyokushinkaikan karate, so there's actual martial arts weight behind the concept. That influence shows in how the character carries himself—it's authentic rather than just anime posturing.
