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!

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!
