George Takizawa, a retired world-champion boxer, runs his own training facility, the J. Country Gym. After leaving the ring, he mentors two boxers: Joe Akamine and Ryuichi Suzuki. His coaching philosophy prioritizes technical skill and disciplined form, placing him at odds with rival gym owner Mr. Matsuda, with whom he has significant disagreements on boxing styles.

His personal life is shadowed by family conflict rooted in his boxing career. His daughter, Maki Takakura, harbors deep resentment towards him, blaming his pursuit of the world championship for her mother's death during that period. This tragedy led Maki to associate boxing with her loss, fostering a strong aversion to the sport. Despite Maki's hostility and her alignment with Joe Yuuki—the rival of his trainee, Akamine—Takizawa maintains a patient and understanding demeanor. He actively seeks reconciliation and desires to rebuild their fractured relationship.

At the gym, Takizawa presents as a grounded and supportive mentor. He frequently visits a local restaurant owned by "Grampa," often with Akamine and Ryuichi, suggesting bonds beyond training. Recognizing Akamine's natural talent, he encourages him to commit more seriously to professional boxing. Firm in his boxing principles, Takizawa remains an approachable and dedicated coach.
