Akira always recklessly runs head-first at any problem. Having just transferred into Nanjou High's part-time evening classes, he picks a fight with the full-time students' baseball club, a favorite for Koushien who are monopolizing the playing grounds. In order to challenge the full-time baseball club on equal footing, Akira will aim for Jinguu, the home of "the other Koushien" for part-time high school students!

Volume 2 includes the oneshots Inochi no Mound and Mou Hitotsu no Koushien.
