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 Seido-Ohya game begins to determine which team will move on to the semifinals. Because Furuya is injured and can't play, the starting pitcher is… Sawamura! But can he really make use of an off-speed pitch he learned less than a week ago against a team of the smartest and slyest players Seido has ever faced?!
