History
The Noise Sisters see a green light and feel it may be related to Jimi Stonefree. They attack Mu and Echo Rec to confirm it. When Mu and Echo get separated, they face Echo, who recognizes them and asks for autograph. The Sisters get super excited as that's the first time anyone asked one and even decide to get one from him too. They still capture him and use him against Mu as they try to awaken Jimi, but Bilin Valentine finds them and defeats the Sisters and save Echo and Mu.
