One Piece: King of the Seven Seas

Story of: One Piece: King of the Seven Seas

(No system + Devil Fruit + Power Management) The beginning is the Shichibukai, yes, the one who was defeated by Ace and doesn't even deserve a name! What? I will be defeated by Ace in a year? How can this be! I am Loki, not a weakling! (This book promises that Red-haired Shanks will die, and he will die before Whitebeard, so that people can't go to the top war to show off.) (The protagonist only plays high-end games, and will not go to the East China Sea to kill small monsters like Buggy and Arlong.)
