Once the World Dance Battle Royale is over, the group nonet is unexpectedly paired with Ootori, a group from the Ootori Song Academy, to put on a play together. The play is an original take on Cinderella with its own special twist. Momoko Asahina is cast as Cinderella and Miyabi Kunishiro as the prince, while Kokomi Shiina lands a role nobody expected. Based on the 3D rhythm game Girl Friend Note, this three-episode music ONA presents a slightly different side of nonet as the two groups work on the production.
