Zero Zone: Amnesia? I'll Make a Knight's Waist with My Backhand

Due to an accidental involvement in the Hollow Incident, Zhe merged with the soul of a tokusatsu fan from the real world. Although he lost his memory, he gained a mysterious ability called the "Earth Library". In order to protect his only family member, his sister Ling, in the crisis-ridden New Elito, he used his ability to "rubbed" the Kamen Rider's belt and memory, and emerged as the Kamen Rider's skull. As his memory recovers, Zhe realizes the nature of this world. When Ling was in danger due to the Hollow, in order to protect her and give her power, Zhe handed over the other half of his power, and the two became "two people in one" Kamen Rider W. Together they faced threats from the Hollow, forces and even the depths of memory, and wrote a story about the tough guy detective and the knowledge princess in New Elido.
