The story of One Piece has always been one crazy roller coaster ride, and that is especially true for the Wano Country Arc. Chaos has always been a staple in every One Piece arc, but the Wano arc brings it to a whole different level. There are six pirate captains from the worst generation and two emperors of the sea, along with most of their crews in Wano. There are also the samurais, ninjas, and some people from the minks there.
