Uzuki, Rin and Mio are the members of New Generations, while Minami and Anastasia make up Love Laika. A mini-concert to promote their respective debut CDs is planned, and the members of both units are preparing with interviews, fitting sessions and the like. Minami and Anastasia are extremely nervous since it’ll be their first time performing on stage, but they do their best to prepare by working together and training a lot.

Meanwhile, the members of New Generations can’t wait to have another onstage experience like they did with Mika. The day of their first concert finally comes, but what do the members see when they look out over the stage?

Miku Maekawa and Riina Tada are going to make their debut as the Cinderella Project's final unit. However, Miku aims to be a cute, cat-eared idol, while Riina's goal is to become a cool rock idol. The two are like oil and water, and both are strongly opposed to the unit idea. But when their participation in the units-only summer festival is on the line, they make an effort to get on the same wavelength, starting with becoming roommates!

It's been a month since the idol festival and the 346 Production Cinderella Project idols are expanding the scope of their activities and grow one step at a time. It's smooth sailing for Producer until a suspicious figure seems to follow him wherever he goes. Does Producer have a stalker!? In between jobs, the idols take turns guarding him.

And then a woman who was working abroad for a company affiliated with 346 Production returns to Tokyo to take charge of the company's idol division. But what startling new policy does Executive Director Mishiro announce!

Miku and Riina are concerned with improving as a unit to get ready for “Cinderella’s Ball,” despite their usual clashes over the direction of the unit. Meanwhile, Riina becomes friends with a rock idol she admires, Natsuki Kimura, whom Executive Director Mishiro has invited to join a new rock-idol unit.

Connecting with Natsuki, who is devoted to rock, makes Riina remember how much she loves it too. Riina is torn over what she wants to do. Miku picks up on the fact that Riina isn’t her usual self and worries about her partner, but decides to wait until she is ready to talk...

Anastasia is positive and determined about participating in Project Krone. But then Mio suddenly announces she's going solo. Meanwhile Rin still can't decide whether to take part in Triad Primus. Amidst all these changes, they strive to find their own paths.

Under the circumstances, it seems like all the previous units and projects will be disbanded, which causes the Cinderella Project members no end of anxiety and upset. The idols decide to band together to make the fall fest a success, but can they?

With the fall fest finished, the Cinderella Project members have ascended another stair. But when Uzuki suffers a crisis of confidence, she tells Producer that she wants to go back to the basics and subsequently returns to training school. Feeling that something is off, Producer frequently visits Uzuki at the school to keep an eye on her, but she sticks to her usual line of "I'll do my best." Producer doesn't think Uzuki is heading in the right direction, so he sets up a Christmas concert for New Generations and entreats her to re-enter the fold there. However, Uzuki doesn't show any enthusiasm for the plan.

When Producer tells Rin and Mio about Uzuki's condition, they become anxious and go to the training school to see how she really feels. They find that Uzuki has lost her former dazzling smile...
