Hiroki, Kohei and Natsuki are the main members of the baseball team at Kenritsu Jingen High School, your average Japanese high school team with no medals, but no epic failures either. When the new semester begins, Hiroki receives a failing grade at a test. If he doesn't pass, he won't be able to part in training camp, so he attempts to retake the test. *Based on the manga series "Chotto Mate Yakyubu! ~Kenritsu Jingen Koukou Yakyuubu no Nichijou" by Takana Yukue
