Expand, Aikatsu's While en route to preparations for the newest Aikatsu Island event, Yume, Rola, and Mahiru come across three idols from Starlight Academy; Akari Ozora, Sumire Hikami, and Hinaki Shinjō. Akari's gang decides to help Yume's group search for four-leaved clovers to give to Hime and the others for the event, learning more about each other. Meanwhile, Ako and Koharu receive help from chef Shun Yotsuba and fellow M4 fans in locating the remaining clovers. Finally arriving at the event, Yume and the others deliver the clovers to Hime's group, who give their reunion performance, before bringing Akari on stage to express her own Aikatsu.
