Prologue: The Harbinger of Doom

Kaizen D Ryu. A man shrouded in mystery and known through the world. With a bounty of 1.1 Billion Berries, he's been given the nickname "The Emperor of Disaster". This due to his incredible power that is only matched by the destructive habits that come with them. One Piece is too long to do on its own so screw it doing other events.

(Side note if you think I'm doing anything as long as the original you're wrong)
