Hachirō Kurogane, an 18-year-old baseball player, is drafted out of high school by the Carbons, a team with a long-time reputation for losing. During his introductory press conference, Hachirō reveals his intention to be season MVP, a difficult task for any player, let alone a rookie. This is because of a promise he made with his childhood friend Suzu Domon, who rejected his confession but said she would reconsider if he ever achieved those goals. With his dedication and goals in mind, Hachirō aims to bring the Carbons to glory and to make the playoffs once again, with the ultimate goal of winning the championship.
