On the way to school one morning, Aoba and Ko foil a burglary they glimpse from the train by hitting the burglar with a baseball, but Senda gets credit for it. Akaishi does not believe Senda foiled the robbery, and learns from Aoba that she threw a ball that Ko had been carrying, and then from Nakanishi that he and Ko have been training in secret. Akaishi takes over Ko's training on the condition that Nakanishi return to the baseball team. At the Tsukishima batting cages, an unknown boy breaks Ko's home run record but complains about how slow the pitching machines are. The boy later appears at Seishu High School, being given a tour for prospective baseball players. Senda visits Aoba while she is working in the Clover Cafe attached to the batting cages and asks about Ko's secret training, but she denies any knowledge about random neighbors. As Ko practices pitching with Akaishi as catcher, the latter describes the dream Wakaba had the night before she left for swimming camp, in which Ko and Akaishi are a playing as a battery in the national high school baseball tournament at Koshien.
