Mariko Hirooka is a new teacher at Mamenoki High School, a private school in the countryside of Kyushu. For some reason, she takes on the responsibility of coaching the school baseball team, which has set a modest goal of "getting out of the first round at prefectural qualifying." The nine members of the team are a little too carefree and easygoing, and they lack proper fighting spirit! However, contrary to all expectations, the team easily wins the prefectural tournament and unexpectedly made it to Koshien! What will happen next?
