Precure All Stars Movie DX3: Mirai ni Todoke! Sekai wo Tsunagu☆Nijiiro no Hana

Hibiki Houjou and Kanade Minamino visit a newly opened shopping mall, only for their search for Hummy to crash straight into a fashion show attended by other Pretty Cures. The confusion grows when fairies and entire pieces of worlds from earlier adventures suddenly begin appearing around them.

Old enemies have united to seize the Prism Flower, the miracle that keeps the different worlds connected. If it withers, those worlds will be torn apart and the girls may never see their fairy partners again. Twenty-one Pretty Cures are forced into one enormous battle, combining their powers across generations to protect the flower and the bonds joining every world together.
