In the process of searching for his missing father, Kit Taylor found an Advent deck - a special deck that allows the carrier to transform into a Kamen Rider and use unique weapons and powers - and used it to become the Kamen Rider Dragon Knight. He had a conflict with Len, who played Kamen Rider Wing Knight, but the two teamed up after Kit learned that the evil General Xaviax had imprisoned his father and used him and other people kidnapped by his monsters to gain power and rebuild his home. Later, Kase, a Ventara survivor like Len, will join forces with Len and Kit to fight against Xaviax. In addition to training Kit to fight like riders, Len and Kase also told Kit the story of twelve riders joining forces to protect Ventara - a world opposite to ours - and defeat Xaviax. However, due to the traitorous behavior of Kit's predecessor Adam, General Xaviax destroyed most of the riders through a program called Venting, which trapped the defeated riders in; Descend to the Void "; Always wandering between dimensions, stealing their descent deck. In addition, Xaviax began to use his transformation ability to force humans to join him, giving each person a descent deck and corresponding Kamen Rider power, which they used to eliminate Kit, Len, and Kase.
