Big Windup! 2

After a falling out with his middle school team, Mihashi enters Nishiura high school with no social skill, a warped opinion of himself, and every intention to quit baseball. The newly formed Nishiura baseball team, however, needs a pitcher, and they welcome him. Most enthusiastic is Abe, a domineering catcher with his own game issues. And so a battery every bit as complementary as it is dysfunctional is formed. If they can figure out how to work together, they might be the answers to each other's problems-and the team might be able to win.

Unaired episode 12.5 included on the 7th DVD & Blu-ray volume. Kurata from Bijyou feels guilty about beating the crap out of other players. Abe’s accidental injury strikes a chord, and he no longer wants to be involved with Roka’s dirty schemes.

One year before the beginning of the story. Kaguyama feels intimidated by Haruna’s presence on the baseball team since he feels that his position as the ace pitcher is threatened. Kaguyama wants to quit, but Haruna talks him out of it after telling Kaguyama about his own past.

With a stray pitch that completely missed the batter, Eijun Sawamura loses his final middle school baseball game. Frustrated by this defeat, Eijun and his teammates vow to reach the national tournament once they are in high school. But everything changes when a scout unexpectedly invites him to Tokyo's prestigious Seidou High School after seeing the potential in his unusual pitching style. Encouraged by his teammates, Eijun accepts the offer, ready to improve his skills and play at a much more competitive level of baseball. However, now surrounded by a large number of skilled players, Eijun struggles to find his place on the team. He declares that he will one day become the team's ace, but that's only if fellow first year Satoru Furuya doesn't take the title first, with his breakneck fastballs that earn him a coveted spot on the starting roster. With the addition of these talented new players to an already powerful lineup, the Seidou baseball team aims to become the best in Japan, facing off against a number of formidable foes that stand in their way.
