Light and Darkness, one cannot exist without the other. Within every heart, there is both light and darkness conflicting with each other. In the center lies the heart of all worlds, Kingdom Hearts.
The Keyblade War has been fought, light may have prevailed, but darkness will find a way to grow. The Heart Keys have been rediscovered and the darkness will stop at nothing to obtain all one-hundred keys and bring back Kingdom Hearts from its slumber. The future however will be unlocked by a few individuals... few Kamen Riders.
