Raki, Aine and Mio manage to return to Star Harmony Academy where, despite spending several days at four Star Academy, no time at all seems to have passed back home. The girls discuss their adventure with Maika and Ema, who become excited about going to Four Star Academy. Unfortunately no one seems to have heard of the school or can find any information on it. However things take an interesting turn when Maika and Ema head to a Honey Cat fan fest, where two mysterious idols appear. The idols introduce themselves as Hinaki Shinjo and Juri Kurebayashi from Starlight Academy and things heat up. (Source: Wikipedia)
