George helps Ikki to tame his inner demon and is present to see them transform into two Kamen Riders. Although George tries to convince Daiji to use the Revice Driver, much to his hesitance, it found it's way onto his older brother Ikki Igarashi. While Kadota attempts to use the belt and Vistamp, he fails and inadvertently created the Rex Deadman. However, the event gets attacked by the Deadmans. During the Fenix appointment ceremony, George stands on stage with Hiromi Kadota to unveil with the audience the Revice Driver.
He also tells him his personal choice to use the Revice Driver, Daiji Igarashi. One day, George reports commander Yujiro Wakabayashi about the Deadman's raid on Fenix headquarters and the loss of several Vistamps.
To carry on his father's work and counteract the Deadmans, George created the Revice Driver and the Rex Vistamp for the user to harness the power of their inner demon. Thirty years ago, his now late father was responsible for the creation of the Vistamps during a breakthrough in separating humans from their inner demons. George Karizaki is the developer of the Rider Systems at Fenix and an overenthusiastic fan of the Kamen Riders.
