The entire King of Prism franchise folds into itself for one absurd, gorgeous victory lap across time and parallel worlds. SePTENTRION's journey doesn't just revisit pretty rhythm, pripara, pri chan, and primagi, it makes their aesthetics collide in real-time, each world's sparkle system layering on top of the last until the screen becomes pure light and music and boy-meets-boy destiny. Animation this fluid and a soundtrack this committed to euphoria don't ask for your permission to make you feel something transcendent about four different magical sparkle universes finally touching.

Shin Ichijou and the six other members of SePTENTRION climb into a time machine and set off through different eras and worlds, searching for the place where Prism Shows first began. Their trip reaches past the edges of their own story and links up with the worlds of Pretty Rhythm, PriPara, Kiratto Pri☆Chan and Waccha PriMagi!. The result is a musical crossover film that brings characters from separate corners of the franchise together, with the dazzling performance spectacle of Prism Shows at its center.
