Love Live! Sunshine!! - S01

After Uranohoshi Girls' High School closes, the third-years, Dia Kurosawa, Kanan Matsuura, and Mari Ohara, have just graduated, leaving Aqours with only the first and second-years. While looking for a new place the remaining members can use to practice, they decide to visit the new school they will soon attend. To their surprise, the building seems to be abandoned. It turns out that because the school board worried about how the newly transferred Uranohoshi students might burden the clubs, they were sent to a branch school instead. This gives Aqours a new goal: to prove that Uranohoshi students are serious about their clubs too. Meanwhile, another problem comes up: the third-years have unexpectedly gone missing during their graduation trip. Love Live! Sunshine!! The School Idol Movie: Over the Rainbow follows the remaining Aqours members as they set out to find their missing seniors and, at the same time, try to find a way to change the new school's mind.
