The pitcher Yuudai and the catcher Shoutarou have been childhood friends and battery-mates ever since they can remember. The third-years have retired from the baseball team, and now it's time for the the second-year players to step up and prepare for the Koushien tournament! However, just before the autumn tournament, Yuudai suddenly starts to have the yips, which threatens his spot on the team. After chasing the same dream and the same white ball for 10 years, their relationship becomes unsettled... Why is Yuudai feeling so uneasy?
