Cross Game 7 features story and art by Mitsuri Adachi.

With his final summer in high school approaching, Ko and the rest of the team are right in the thick of the regionals to qualify for Koshien. They manage a win in their first game, but the next round pits them against Kurokoma, led by none other than Seishu's infamous former coach, Daimon.

Seishu is cautious because they know Daimon would really hate to lose to the "Portables" twice. And as the team battles its way toward Koshien, Akane Takigawa is dealt a blow to her health and is hospitalized.
