Yuu Morisawa once lived a secret double life as the magical idol Creamy Mami, until her powers vanished and Mami gave what was supposed to be her final concert. Two months later, rumors suddenly spread that the vanished star is returning to the stage, complete with a mysterious project being prepared by Shingo Tachibana.

Yuu knows she cannot simply become Mami again, so the announced comeback makes no sense. Together with Toshio, Megumi, Midori, and Kidokoro, she begins investigating the strange preparations. The search draws old memories and unfinished feelings back to the surface as Yuu tries to uncover who is using Mami's name and why the idol everyone said goodbye to seems ready to sing once more.
