When Yoko gets a singing gig at an intergalactic concert hall, she's totally excited. And when she plays to an enthusiastic, sold-out crowd, she finally feels like she's on the path to becoming famous! When she returns to Galaxy High, she finds herself showered with flowers, gifts and poems -- all sent to her courtesy of the Yoko Maniacs -- her official Fan Club. And when she gets an invitation to appear at an upcoming fan club meeting, she can't resist! When she arrives at the meeting, however, Yoko is confused to find only a single alien fan there. What she quickly realizes is that the alien, who has the ability to shape-shift, has lured her there with the intention of capturing her and taking over not just her appearance, but also her new career!
