One Piece: Mamore! Saigo no Oobutai

Former Marine lieutenant Randolph now leads a traveling theater troupe aboard his ship, using stories to encourage people who have suffered at the hands of pirates. As age forces him to retire, he prepares one final performance, and the Straw Hat crew unexpectedly becomes part of the show.

A bitter former subordinate returns with authority and a plan to frame Randolph as a criminal. Luffy and his friends must protect the troupe, expose the commander's grudge, and prove to the audience that a pirate's flag does not decide the worth of the person beneath it.
