A/N:This is a prequel to all my other soon-to-come stories as soon as I am done with this. This is also my first fanfic so cut me some slag. I also won't use "san" "kun" and "chan" that the Japanese use.
The beginning
"Damn you, Decade!" was all Tsukasa aka Kamen rider Decade heard from Narutaki aka Doctor G before he said, " because of you 12 worlds will be destroyed!" Tsukasa was dumbfounded when he heard that as Narutaki dies.
A/N that's all for now. I hope you enjoyed the intro which I hope so. The next chapter will tell you whose world will be destroyed first. P.S, I do not own Kamen rider.
