航海王：强者天下

The era is the "Great Pirate Age." One day, upon learning of a crisis in their hometown, the "East Blue," the Straw Hat Pirates decide to temporarily suspend their adventure and return to the East Blue. At that moment, they spot an unknown pirate ship in the sky. Nami predicts an approaching storm and uses a "Tone Dial" dropped from that ship to warn them. After the storm passes, the ship's owner, "Golden Lion" Shiki, arrives on the Thousand Sunny. He offers to use his "Float-Float Fruit" ability to carry Luffy and the others back to the East Blue as a token of gratitude, much to their excitement. However, midway, Shiki suddenly cancels the Thousand Sunny's buoyancy and seizes the opportunity to kidnap Nami. It turns out Shiki has taken a liking to Nami's ability to sense weather with her body and wants her to become the navigator for his pirate crew. Meanwhile, Luffy and the others plummet from the sky along with the Thousand Sunny onto the floating island "STRONG WORLD." The scattered crew members are forced to battle the island's various evolved and ferocious beasts. The legendary pirate "Golden Lion" Shiki is a figure whose strength rivals that of the "Pirate King" Gol D. Roger and "Whitebeard" Edward Newgate. He is a legendary pirate who stirred up great chaos since Roger's era. Twenty years ago, he became the first prisoner to successfully escape from the "Impel Down" underwater prison. After his escape, Shiki spent twenty years vowing revenge on the entire world. The first step of his revenge plan is to destroy the entire East Blue. To protect his hometown and his crew, Luffy, who aspires to become the "Pirate King," engages in a top-tier showdown with Shiki. Who will emerge victorious and dominate these seas...?
