While taking Manaka to practice her new song in a karaoke bar, Hyodo unexpectedly spots Retsuko singing death metal. The next day, Hyodo announces that the idol group will change their genre, and appoints Retsuko to be the new lead singer. Initially, Retsuko refuses, as she doesn't want to let the world know of her death metal singing. Manaka tells Retsuko to step up and stop worrying about stepping on other people's toes. Later that night, Retsuko is pressured into, and eventually accepts, her new role as the lead singer for the OTM Girls.
