In "Cross Game," Kou Kitamura and Aoba Tsukishima are constantly at odds, even though their families are close friends and business partners. Kou, the only child of a sports store owner, has no interest in baseball, despite developing his batting skills through regular visits to the batting center run by the Tsukishima family. Meanwhile, Aoba is passionate about baseball and shines as a pitcher.
Although they seem like complete opposites, Kou and Aoba share a deep bond through their feelings for Wakaba Tsukishima, Aoba's older sister and Kou's destined love interest. Wakaba often sparks their ongoing rivalry. Whether they will eventually recognize their common ground is uncertain, but baseball might be the key to resolving their personal struggles.
