This is the story of Natsunosuke Honda, a professional baseball player—a relief pitcher who has been with the Spiders for 8 years. The squad is structured as a highly stratified society, with the player's performance determining his annual compensation. Natsunosuke is one of the game's highest-paid players. He assesses how excellent players are by how much money they earn, and he wants to be at the top and stay there, so he is always seeking for guys to challenge and does everything he can to ensure that he is better than them.
