In this Theatrical crossover movie, which takes place a few months after the final episode of Kamen Rider Wizard, Haruto takes a break from traveling to find a place to lay Koyomi's soul to rest to reunite with the rest of his friends from the series when he is suddenly attacked by a Phantom called Ogre that can eat other Phantoms and gains their abilities. After defeating Ogre and becoming his own hope, Haruto and Nitou are transported to another dimension.
Meanwhile, the Armored Riders of Zawame City are competing in a Royal Battle competition when they two are transported to the alternate dimension, which resembles Japan's Warring States Period and is inhabited by people represented by Kamen Riders who are being called Warrior Gods. What is this world? Why have the riders been brought here, and how can they get home? Wizard, Gaim and the others will have to work together to find out.
