During her junior high years, pitcher Yomi Takeda failed to advance far in a cross-school baseball tournament. Because her team's catcher was not at her level, she was unable to utilize her signature move, the "Magic Throw," and she eventually came to regret not being able to use it.

There, she reunited with Tamaki Yamazaki, her long-lost childhood friend, who had played catchball with her in their youth. Tamaki also played baseball as a catcher during her junior high years and was capable of catching Yomi's "Magic Throw!" The promise they made to each other in childhood could now be fulfilled! Walking the path of baseball together once again... The story of these girls who love baseball begins!
