Kyousuke implements a Battle Ranking system, with Riki slowly moving up the ranks, while Yuiko has fun teasing the other girls by giving them dubious advice. Meanwhile, a mysterious fighter known as Mask the Saito appears and starts defeating other members of the Little Busters and moving to the top of the rankings. Mask the Saito then confronts Riki in a battle, but he is stopped by Komari reciting a moving story and admits defeat, revealing himself to be Kyousuke, who passes the mask onto Riki.
