Cross Game 2 is an omnibus collecting Japanese volumes 4 and 5 and features story and art by Mitsuru Adachi.

Wakaba's last dream before she set off on that fateful day was of Ko pitching in front of a packed house at Koshien. Ko's been training every day since, trying to emulate the best pitcher he knows: Wakaba's sister Aoba. But will Aoba's seeming hostility toward him and a new high school coach who only cares about winning prevent Ko from fulfilling the dream?
