The last words uttered by Gold Roger, the Pirate King, before his death, ignited a frenzy, and the world entered a new era - the age of pirates! On the brink of an adventure in the Grand Line stands a band of young pirates: Monkey D. Luffy, who possesses the ability to stretch like rubber; Roronoa Zoro, known as the Pirate Hunter; Usopp, a skilled sniper; Sanji, a chef who thrives on the sea; and Nami, also known as the Cat Burglar, each of whom places their foot on a barrel and make their vows before setting sail across the vast ocean. Luffy's pledge resonates above the rest - "I will become the Pirate King!" A decade prior in Windmill Village, a young Luffy becomes enraptured by pirate captain, Red-Haired Shanks. However, when mountain bandits ridicule the group, Luffy demands to know why they didn't fight back. Shanks tells Luffy to let it go. After Luffy eats a piece of Gum-Gum Fruit and acquires stretchy abilities, he cannot swim for the remainder of his life. Days later, he's attacked again, and Shanks comes to his rescue, vowing to protect his friends. His bravery leads him to lose an arm when a sea monster attacks. Before leaving, Shanks gifts Luffy his straw hat, with the promise that he'll return it when Luffy becomes a great pirate. Fast forward ten years, and Luffy's journey to become the Pirate King has officially begun, marked with him single-handedly defeating the once-daunting local Sea Monster.
