Centuries ago, there was a battle between humans and a unknown alien race that called themselves Mysticans. In the past there was two warriors kept monsters at bay, until one day. The warrior with the motif of the beetle betrayed his friend and almost caused the human race to be extinct. Now, in the 21st century: a archeologist will uncover the power that laid dormant for centuries when the Mysticans rise from their Earthly tomb. This man must become someone else, he must become something else. On this vacant planet an era begins from zero and legends will be repainted. This is a old legend with a new hero. Based off of the hit 2000 show, Kamen Rider Kuuga.
