Uzuki and Rin come to 346 Production for the first time. They meet the final member who won the idol version of a “second chance sweepstakes,” Mio Honda, as well as the 12 other eccentric members, and thus the project can finally start. The first job for the three newcomers is to do a publicity shoot, but their nervousness threatens to derail the whole thing. Somehow, they get through it, and well enough to impress superidol Mika Jougasaki, who suddenly hires the trio to be her backup dancers for an upcoming concert!

Two units are going to make their debut, one with Uzuki, Rin and Mio, the other with Minami and Anastasia. They all become busy with lessons to prepare for their mini-concert debut. However, Miku's frustrations boil over dangerously when her own debut can't be seen on the horizon.

The project that Producer proposes to Executive Director Mishiro is called "Cinderella's Ball: Power of Smile." It's meant to be a complex event that will showcase the idols' individual strengths. Though Mishiro's proposal runs completely counter to this idea, she gives Producer permission to run with it. Producer and the idols will be able to prevent the gutting of their division if they show results within a certain time frame.

The Cinderella Project idols are happy about this reprieve, but idols in other departments, particularly those whose strong suit is with variety shows, find themselves facing changes due to Mishiro's course of action. And one of them is the eccentric Nana Abe, who claims to be from the planet Usamin! Cat character idol Miku worries about getting the ax, while Riina worries about Miku...

After Totokira Academy gets off to a popular start, Candy Island makes a guest appearance on the show. Chieri and Kanako are so nervous that they act stiff, but with Anzu's casual support, they make it through the taping. The staff loves the stark differences between Anzu and Kirari and gives them a new recurring segment, "Anki Ranking." Chieri and Kanako agree to do to a taped interview for that segment, but Anzu worries about them in her own way.

Seeing how hard everyone is working for the upcoming ball, Chieri and Kanako get fired up, but their nervousness prevents their true talent from coming out, and the interview becomes a hard battle...

The fall fest held by 346 Production has begun at last. The Cinderella Project idols are each determined in their own way and fired up as they face the concert. Per Producer's decision, New Generations is sitting the concert out, but Mio and Uzuki are on hand as staff to support the others, while Rin performs with Karen and Nao to make their concert debut as Triad Primus.

Meanwhile, Anastasia performs solo for the first time on stage and all the other Cinderella Project idols shine more than ever. On the other hand, it's the first time for the Project Krone idols to be on stage. Their nervousness reaches its peak right as they're about to go on...

The Cinderella's Ball finally begins, with the Cinderella Project girls encouraged by Producer to smile as they do each of their routines.
