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! Seido has passed the third round of the Fall tournament. But with the quarterfinals only a week away, Furuya faces an injury that might leave him unable to play! What is necessary for the team to advance? And what is Sawamura lacking as a pitcher? Could this be the major shake-up Seido needs to win the tournament and move on to Koshien?!
