The concert is a success, and Kyō and the girls' next step is to gather more public to make a steady income from their gigs. By suggestion of a friend, Kyō decides to make a PV of them for advertising.

Kyō discovers that his online friend was not Yuzuha, but Kiryu Yume, and Yuzuha was acting in her stead. When Kiryu decides to cease all connections with Kyō and the others, they decide to find a way to cheer her up.

Enraged with how much time Kyō spends with the girls of Lien de Famille, Kiryu decides to form her own act with Yuzuha and Kurumi's help and challenge them to a duel. In the occasion, Jun expresses her wish to write a music of her own, and Kyō agrees to help her with it.
