One Piece: Surrounded by the Demon-Slaying Order

Who said that in the world of pirates, you have to be a pirate or a navy? Overthrow the world government? That's what the revolutionary army did. Protect the people? That's what the Navy does. Looking for one piece? That's what pirates do. Save the world? That was Luffy's doing. One is a down-and-out agent with the power of a useless Devil Fruit with a long tail, and the other is a fish-man who can't swim after eating a fish fruit. Revenge of the Celestial Dragons? Stop dreaming. The only way to survive in this cruel world is to earn money and then invest in Luffy, the chosen one. This was originally Nara's plan. However, everything changed when the woman showed up: "Hello, I'm Nico Robin." At this point, the whole world is under a demon-slaying order.
