The League of Villains devises a plan to attack Class 1-A by breaking into their dormitories. Their dorm building becomes an all-out battlefield and the students believe they have the upper hand. Unfortunately for them, the League has a trick up their sleeve. In just seconds, Kurogiri sweeps the students into a vortex, letting them freefall to their doom. The class is divided into five groups of four, crash landing in various parts of a whole new universe - the shinobi universe. Follow class 1-A as they make an attempt to find each other and find their way home. They might even have to... participate in the Fourth Great Shinobi War?!
