One Piece Manga Chapter 864

While trying to escape Impel Down, Usopp is forced to team up with Doflamingo. They manage to defeat their pursuers, but their partnership ends when Doflamingo learns a crucial detail about a chocolate bar Usopp gave him. A series of deceptions orchestrated by Bentham allows Usopp and Franky to finally escape the prison.

Disguised as a Marine, Usopp is taken to Marine Headquarters, where his talent for comedy impresses Sakazuki, who repeatedly promotes him. Smoker unmasks him, forcing Usopp to flee. Koby argues that a good comedian is too rare to be captured, distracting the Marines and allowing Usopp to escape back to the Thousand Sunny.
