Kamijo Ren, once the knight "Kuga" who saved mankind, now bears the name of corruption.
Driven by fate, he gained the ability to travel through many Kamen Rider worlds.
In order to find the lost truth or seek revenge, he gradually pushed each knight's world into chaos.
The science of Build, the reasoning of W, the game of Ex-Aid, the mystery of time of Decade...
The knight in each world will become his stepping stone to the "ultimate emptiness".
Justice has been blurred, order will collapse,
An unprecedented "Knight's Tribulation" is about to begin!
