What are big brothers for? When the arrogant young studs of the Nekomi Baseball Club try a squeeze play on Megumi and her tiny Softball Club, it's up to Keiichi to help his little sister keep her club alive, and win a playoff match for the right to use the baseball diamond for practice. Of course, Megumi has three goddesses on her side. But the Baseball Club will stop at nothing to win the game, and get Megumi and the goddesses to work for them as Baseball Club gophers!
