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.

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!
