Late afternoon at school, Sumika and Ushio catch two girls kissing each other. When the next day's discussion turns to first kisses, Ushio gets the crazy idea of having a practice first kiss. Sumika, feeling a bit dejected that Ushio would rather practice on a model skeleton than her, and decides to take up karate again, having previously quit because she felt it was not cute. The next day, Ushio asks Sumika to meet her after school. Assuming Sumika had someone else in mind, Ushio lets her have her practice first kiss on her while wearing an Ultraman mask. As she does, they are watched by the two girls that Sumika and Ushio had seen kissing each other before.

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.

Azusa gets psyched to prepare a doujin for an upcoming yuri convention, assuming Sumika would help her with it. Ushio decides to distance herself from Azusa so that Norio's secret identity won't be found out. Tomoe plans a trip to the beach for her 'club', tempting Sumika with the thought of Ushio in a swimsuit. Thinking about Sumika, Azusa is inspired to work on an original story as opposed to a doujin, and spends many nights working on it with the hopes of showing Sumika the final result. However, she becomes very depressed when Sumika can't remember offering to help, and runs home to cry. Having noticed her, Tomoe brings Sumika over to Azusa's house so she can see the work Azusa had done and apologize.
