Yakyuu is CUTE!! During her middle school years, Takeda Yomi was a pitcher for the baseball team, who faced defeat in the first match. Carrying regrets about not being able to throw her "magical pitch" due to not having a catcher, she enrolls in Shinkoshigaya High School, where the baseball club is currently on hiatus. There, Yomi reunites with her childhood friend, Yamazaki Tamaki. Having worked hard as a catcher, Tamaki is able to receive Yomi's full-powered pitches. The battery, reunited while keeping the promise they made as children, begins to walk the "path of baseball" once again after having paused for a while! The story of girls who love baseball begins!
