This chapter opens with a discussion between Mizuho and the Host of the Show, who introduces himself as "Soleil." He tells the Host that he is a member of the Host Club and that he has been involved in the production of a number of shows, including the one he is currently in charge of. He also tells the Hostess that he would like to help her with the show, since he has worked in the control room for many years. He tells her that he thinks he can help her by taking care of the simple tasks of running the club. He then tells her about his father, who told him that he came into the world for the purpose of becoming a priestess at the school. He adds that it is his job to make mistakes and turn them into something that will add to the success of the show. The Host then tells the listeners about the upcoming show, which will take place in an open studio. She introduces herself as "rothion," which means "secret organization." She explains that the frequencies of the tuning scale are tuned to 444 and 528 hertz, and that they have been used to heal the psychological trauma of many people. She also tells him that trikumia used her voice to take her in for the show because she is a soothing voice. She tells him to say hello to her, and he does so. She then tells him about the secret organization and how it has been used in the past to heal people's psychological wounds. She adds that she believes that the frequency can also be used to repair psychological trauma. She says that the same applies to her voice. The Hostess then tells them that the show will be held on the following day, and she promises that they will have fun in the open studio and then go home. She reminds them that they still have a lot of abandoned research to complete in the village.
