As Sumika recognizes Tomoe Hachisuka and Miyako Taema as the girls she and Ushio saw kissing the other day, Tomoe whispers in her ear that she saw her with Ushio. Tomoe reveals to Sumika her vision of a girls only club, and Miyako attempts to blackmail her into joining, but Sumika tells her that she and Ushio are not a couple. Both Tomoe and Miyako notice that Sumika has a crush on Ushio, who they later convince into joining them, leaving one more member to find. Sumika decides to use Masaki's cross-dressing skills in order to get reactions from potential girl-liking girls. He goes a bit over-the-top with his confessions and scares everyone off. Sumika decides to try again with his usual wig he wears when cross-dressing as Akemi Yamasaki, but when Ushio spots him, he is enrolled into the club and 'Akemi' is made into a transfer student. However, the club application is rejected.
