A 52-episode Kamen Rider fusion fic with forms based on the Crystal Gems from Steven Universe. Equestria's dark side has manifested as an ancient monster-creating superbeing called Equestria Vlitra. When the Mane 6 try to fight it with their Rainbow Power, they are killed and Rarity, being half-Gem, regenerates on a Gem planet. Even worse, Vlitra is sending monsters to hunt down Rarity and destroy the planet she's on! By unlocking her gem powers, she fights back with style.
