Due to Minami's injuries, Kanata is asked to fill in for her in an upcoming concert on the snowy planet Thundristar, much to Minami's dismay. As the understudies explore the planet and see how people under the entertainment ban are like, they meet a group of young fans who are looking forward to the concert. As Nagisa sings to cheer them up, Tsubasa decides to hold a multiple co-ordinated concert with the understudies in order to distract the DES whilst the main concert takes place. Before the concert begins, Minami demands to participate despite her injuries, much to Kanata's disappointment. As Kanata escorts Minami after she comes down with a fever at the end of the concert, Minami understands a bit more about Kanata's passion and once again feels she deserves to be Minami more than herself.
