Deciding that she first needs to 'define what the team is', she talks with Masayoshi Nakai, who hopes to become the team's CEO someday. Later, Yuki recalls a memory on how moved she was when Minami scored a winning bat during elementary school, which inspired her to join the baseball club. Having determined what the goal of the club is, Minami's decides to move onto the next step: Marketing.

Whilst trying to figure out how to apply marketing to her management, Minami becomes curious about the team's pitcher, Keiichirō Asano, who rarely shows up for practice, and co-manager Ayano Hōjō, who is very shy around others. Yuki mentions that Keiichirō is an alumni who rejoined his team, but became distant when he heard his favourite teacher got fired for allegedly beating students. Later, Yuki manages to get Ayano to talk about why she wanted to join the club, talking about how she wanted to change herself and make friends with others. Afterwards, Minami and Yuki hold interviews with the teammates to find out what they want out of the club. When it comes to Keiichirō's turn, he expresses dislike towards the team's coach, Makoto Kachi, who pulled him out of a recent game as he was concerned for his body's limits.
