Hiro Kunimi loves baseball and was the star pitcher of the youth team until he injured his elbow. Much to the dismay of his friends, Hiro has decided to give up his beloved baseball, even going so far as to burn his glove and enroll in one of the few schools without a baseball club. Hiro then joins the soccer club and decides to throw himself into the sport. One day, in a bid to humiliate the Baseball Fan Club – run by the clumsy Haruka – the Soccer Club challenges them to a match. Disgusted by their arrogance, Hiro decides to quit the Soccer Club halfway through the game and joins the Baseball Fan Club instead! It seems that Hiro’s desire to play baseball and his dream of reaching Koshien are too strong to simply ignore after all.
