Four years later, in the fall of her second year at Seishu Junior High School, Aoba is a pitcher for the baseball team, and still hates Ko for having monopolized her dead sister's time. Starting pitcher Keiichiro Senda, who considers himself popular, asks her out on a date without waiting for a response. When she does not show up, Senda goes to her house but is frightened off by the family cat. When Ko (in his third year at Seishu Junior High) delivers baseballs to the Tsukishima batting cages, he hits four home runs, which annoys Aoba, especially since she cannot match it. In a flashback, she remembers Wakaba telling her about Ko's potential to one day pitch 160 km/h fastballs, which Aoba claimed was her ideal in a man, but that if he does, Aoba cannot take him from her. Meanwhile, inspired by Aoba's pitching, Ko has been obeying Wakaba's order to follow Aoba's workout routine.
