Riki's next step to reassemble his friends is to convince Kengo to join their side, but Kengo refuses to listen to him, claiming that all Riki and Rin need to do is to rely on their friends. Riki visits Kyousuke, who hints that Kengo is lying about something and Riki realizes that Kengo's arm is not injured as he claims. Rin learns from Masato that Kengo originally joined the Little Busters after Kyousuke defeated his father in a kendo match. This leads Riki to challenge Kengo to a baseball match instead, with the first one to strike a home run being the winner and Kengo rejoining the Little Busters should he lose. After several attempts, Riki manages to land a home run but is too exhausted to throw the ball, so Rin takes his place. Rin's throws are fast but with initially no control, and when she manages to throw the ball properly, she succeeds in having Kengo strikeout, winning the match. Kengo rejoins the Little Busters, determined to follow Riki as long as he can.
