Takao Taniguchi was the captain & pitcher of his junior high school's baseball team, but after suffering a fractured finger during a game Takao enters Sumitani High School as a fan and not a player. Even though Takao joins the soccer team and shows potential, he still has a great love for baseball and still umpires games in secret until his coach hears of this and gets angered, forcing Takao to leave the team. At the recommendation of the soccer team captain, Takao joins the Sumitani baseball team... Unfortunately, the team is notorious for losing big games due to their inexperience.
