One more time, I'd like to pitch into that mitt ... Eijun Sawamura's life changed in an instant when he first met catcher Kazuya Miyuki. At fifteen years old, he says his farewells to his friends and goes to the famous baseball high school Seido High. There, he will find prideful players who have put it all on the line for baseball! The path to victory is unfamiliar ... Seido's players devote themselves to grueling daily practices. First-year Tojo tries to distinguish himself and raise the team's morale, but the results of the practice games are not up to snuff. Then, the super high school level slugger Raichi Todoroki and his Yakushi high school team are chosen for a practice match! A serious game to test the abilities of the new team has now begun!!
