In trying to come up with a dress idea to rival Elza's Star Wings, Yume is told by her brand owner to think about what she herself would enjoy. While trying to find her answer, she comes across Lily, who has decided to make the Premium Rare Dress she had sealed away before in order to obtain the Star Premium Rare Coord. As Yume and Yuzu both help her with her training, Lily finds inspiration from a bird and manages to complete her new dress, the Rosetta Thorn Coord, which is granted its own set of Star Wings.
