Titre original : Chance and Try ☆
Mizuki decides to hold an audition at Starlight Academy for two partners to form a new idol unit, Tristar, with her. As all the students spend the next week training, the girls hear from Aoi about how Mizuki once tried a team audition shortly after becoming the Starlight Queen, but failed due to her skill being far beyond her teammates. The audition begins with an obstacle course, with the idols first required to climb a steep wall which is made more difficult due to Naoto spraying water everywhere, eliminating the contestants down to fifty. They next have to cross a balance beam while being bombarded with volleyballs, followed by having to finish a song while riding a mechanical bull, reducing the contestants to twenty. After Yurika gets eliminated due to keeping her character during a crawl against a giant fan, eight idols remain for the concert stage which, besides Ichigo and the others, include the three girls that entered the team audition with Mizuki two years ago. After the eight contestants perform, Mizuki announces that Ichigo, Aoi, Ran and the three former teammates will compete in a final audition the next day. Just then, a mysterious girl named Kaede Ichinose skydives in from above.
