One day he woke up and found that he had inexplicably traveled to an uninhabited island in the world of One Piece, and activated the Kamen Rider Emperor Riding System! After surviving on an uninhabited island for half a year, he encountered a group of pirates who broke into the island. After defeating this group of pirates, he learned that the current time period was two years before the plot. Where should he go from here?
