Ten years of Aikatsu Stars! get a celebration on the big screen. This music film marks the franchise's tenth anniversary. The franchise began with Yume Nijino, a girl who dreams of becoming a top idol and enrolls at Four Star Academy, where first-year students compete for a place in the S4, the school's four leading idols. A later entry brought Elza Forte and her idol cruise ship Venus Ark, with Yume as her next target.
