Thirty years after the story of Touch’s main character, Tatsuya Uesugi, the door opens again on the story of these two fateful brothers…

Souichirou Tachibana and Touma Tachibana are two boys with the same birthday who happen to have become twin (?) brothers due to their parents remarrying. The two are second-year middle school students who attend Meisei Academy’s middle school.

Souichirou is a catcher and a batter. Touma is a third baseman for some specific reason, however he’s actually an excellent pitcher but has decided to conceal this. Then, there is Souichirou’s blood-sister and Touma’s step-sister, Otomi Tachibana. She has just entered into middle school and the two boys have become even more lively.

Now that the two are getting ready for high school, will they be able to set foot on the pitcher’s mound at Koushien...?
