Episode 291

"Boss Luffy Returns! A Dream or Reality Lottery Trouble" is the 291st episode of the One Piece anime.

Short Summary
The Straw Hat Pirates and the Buggy Pirates are in an alternate reality based on feudal Japan, called Jipangu. Buggy tries to sell Rika as a slave to make up for Pandaman's debts, who Buggy thinks is Rika's father. This is one of the only few episodes where Luffy uses a weapon, A small Jutte (throughout the series, Luffy also uses a Katana during the Thriller Bark Arc when he absorbs a marine swordsman's shadow. He also uses a gun at one point to save Nami). Though he just carries it in his hand while he punches.
