In this Hyper Battle Edition of "Kamen Rider Unicorn", Sunset Shimmer and Rainbow Dash have been working tirelessly as Kamen Riders Unicorn and Nasca to defend their home from the ever-increasing threat brought about by the arrival of the Gaia Memories, strange USB shaped devices capable of transforming the user into a terrifying monster called a Dopant.

However, when a new Dopant surfaces, stronger than anything they've ever faced before, will our heroes be able to summon the strength to vanquish this beast, or will Canterlot be razed to the ground?

"Time to restore Harmony!"
