In the game, the player takes the role of an unnamed former little senior league baseball ace who lost his or her baseball career after suffering an unspecified injury. The character moves to his or her grandmother's hometown and enrolls in the local high school, resolved never to enter the world of baseball again. When the character meets Tsubasa Arihara, he or she is persuaded to be the manager of the school's baseball team, and to take the team to the high school nationals at Koshien.

In the game, players gather team members (there are over 50 characters in the game) and experience the team members' stories. Players also train the members to improve their skills, and take members to games to compete. Players then have to decide on the batting order.
