At the start of a new school year, Touma and Souichirou secretly begin practising to help their baseball team make it to the Koshien Tournament for the first time in 30 years.

Otomi adopts a dog, naming him Punch; the Meisei baseball team tries to decide who should be the club's ace pitcher.

The junior high team barely makes it through the national juniors preliminaries; Souichirou and his brother's relationship comes to light.

Daisuke's expert pitching impresses the team, but when the team goes to the Tokyo Tournament, Daisuke fails to appear at the start of the game.

After Nikaidou's pitching fails to land the team a win, a pitcher from the opposing team offers to transfer to Meisei High.

Daisuke has a reason for missing practices; the team gets a new manager just in time for their new season.
