I Transmigrated to the World of One Piece, and I’m Going to Be King of the Pirates

Transmigrate to the world of One Piece? I even get to talk with two of the Four Emperors and take part in the Paramount War! I want to change the ending and save Ace, the person everyone wishes could have been spared. Whitebeard dies in battle, but thanks to the System, I get a replica of the Tremor-Tremor Fruit. Now I have what it takes to rule the world of pirates. My goddess, Boa Hancock, at last, in the world of One Piece, you and I are together! I'll seek out the strongest masters and learn the three advanced forms of Haki. I'll form a pirate alliance with the Straw Hat Pirates and journey to Laugh Tale together. We'll assemble an army of ten thousand pirates, overthrow the dark World Government, and fulfill my promise to the Pirate Empress Hancock: the people of the world will never again be slaves to the Celestial Dragons. No matter how powerful our enemies are, sorry, but Luffy and I are the chosen ones of this world!
