It has been 3 years since his dad passed away, but at age 9 Goro is finally old enough to enter Little League Baseball. He returns to the field of the Mifune Dolphins, but when he arrives he learns they only have 5 players and that the team could be folding. To make things worse the soccer club has gotten permission from the city to fully take control of the field. The coach recommends Goro goes to the other Little League team in the city, but Goro is determined to play for the Dolphins and begins recruiting his classmates to play.
