Ace of the Diamond, Volume 31 (Ace of the Diamond #266-274)

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!

After vowing revenge on their rival team, Inajitsu, in the following round, Seido easily defeats Nanamori and advances in the Fall Tournament. However, Inajitsu struggles against their own second round opponent, Ugumori, whose ace pitcher, Umemiya, pins them down with his tenacious pitching arm and an aggressive offense. Perhaps?
