Kokusho Sayuri, a member of Onyanko Club and a friend of Yukino, visits Saki. She, Saki, Yukino and Kyoko go to Harajuku together. In the chaos of Harajuku, Sayuri gets kidnapped. Without her, the live TV program "Yuyake-nyan-nyan" can't be on the air. Other Onyankos also go out to look for Sayuri.
Saki gets information about Sayuri that although it's forbidden to have a close relationship with boys in the Onyanko Club - Sayuri has a boyfriend. The kidnapping is a plot that the boyfriend made, that by hiding her and making her skip the live TV show, he could make her quit Onyanko and he could see her as frequently as possible.
Sayuri realizes how selfish the boyfriend is, and she breaks up with him. Saki is invited to the live recording studio and she performs in front of the camera the first time in her life.
