劇場版プリパラ みーんなあつまれ! プリズム☆ツアーズ

"PriPara the Movie: Everyone, Assemble! Prism☆Tours" is a Japanese animated film released in 2015, serving as the first theatrical installment of the "PriPara" series. Set in the idol-themed amusement park "PriPara," the film follows Laala Manaka and other idols on a tour of performances. A notable feature is the branching storyline, where viewers choose between four routes, each with unique plot elements, but all lead to the same ending. The film also incorporated an "cheer-along" screening, encouraging audience participation as if at a live concert. Featuring characters from both "PriPara" and its predecessor, "Pretty Rhythm", the film creates a large-scale idol celebration. It was well-received by fans and is seen as foundational for later films, and inspiring spin-offs like the "KING OF PRISM" series.
