Rinne's first Prism live was in Episode 4 with Naru, but she did her Prism Live by herself in Episode 9. She already had her wings in the beginning of the story, but they evolve in Episode 39. Rinne's My Song is called "Gift" and was first heard in Episode 9. She successfully performs five consecutive Prism Jumps in Episode 39. She formed a unit with Juné in Episode 39 in order to be able to participate in the duo-only competition, Winter White Session. Their unit song is called "Sevendays Love, Sevendays Friend" and was first heard in Episode 43. She successfully performs 6 consecutive Prism Jumps in Episode 43 along with Juné. In Episode 50,she gains her Grand Rainbow Crown and returns to the Prism World. Rinne loses her memories of Naru and the others once she returns as the Prism World's rules dictate, but uses the phrase "Happy Naru!", explaining to Starn that she heard the phrase from a world she once spread the Prism's Sparkle to.
