Shin Ichijou and the other six members of SePTENTRION will travel across time and worlds in a time machine to the origins of Prism Shows. It will cross the boundaries of the series and intertwine with the worlds of the "Pretty Rhythm" series, "PriPara" series , "Kiratto Pri☆Chan", and "Waccha PriMagi!" to deliver a sparkling Prism☆Tours. Fated boy meets boy, our worlds are now connected by the prism's sparkle! (Source: Official Website, translated)
