Nagata, Seihō High School's ace pitcher and a right-handed thrower, wields a powerful fastball as his primary weapon, consistently clocking around 145 km/h. Leading Seihō's pitching staff in the competitive Tokyo fall tournament, he faces Seidō High School. Nagata initially overpowers Seidō's lineup early in the game. However, significant difficulties emerge against Seidō's cleanup batters, especially Miyuki Kazuya and Zono Takashi, who drive powerful hits off his increasingly vulnerable fastball. The pressure of the game and the opposing hitters' power visibly impact Nagata's composure and performance during this critical matchup. After his high school career, Nagata pursues professional baseball, joining the Yokohama Marines as a pitcher. His professional trajectory includes progression through the Marines' minor leagues.
