Utsuki, Rin and Mio start taking lessons to train to be Mika’s back dancers. It’s a long, hard struggle, but thanks to the encouragement of the other project members, they somehow make it. But the pressure of being on stage for the first time has stressed the trio out so much that even the final rehearsal doesn’t go well. Will they be able to get it together for the actual concert?

The summer fest is here at last. All of the project members are nervous about performing on the grand stage, but their rehearsals go smoothly thanks to Minami's leadership. But then Minami collapses from accumulated stress. Ranko does an emergency fill in for Minami with Love Laika and somehow, the rest of the Cinderella Project's performances go off without a hitch... until a sudden downpour causes the rest of the concert to be canceled!

Executive Director Mishiro announces that the division is going to start anew and cancels all current projects. Furthermore, she proclaims that she will pick the idols as part of one grand project. Her policies are very different from that of Producer, the Cinderella Project, and other departments within the company.

There's a lot of anxiety as idols are driven out of offices they've always been in and relocated, while Producer works hard to protect their department by presenting a plan in place of hers. Then Executive Mishiro calls 346 Production's top idol, Kaede Takagaki, in for a private meeting!?
