One Piece: Season 5, Voyage Four is a 2 DVD set of the hit anime series One Piece. The series takes place during the fictional Great Pirate Era. The Pirate King Gol D. Roger was executed 20 years before the start of the series. Roger was the only person to attain wealth, fame, and everything that the world had to offer.

The main character ‘Straw Hat’ Luffy, who is able to stretch like rubber because of a Devil Fruit, sets out on his journey to find the One Piece and become the new Pirate King. He brings together eight other crew members during his travels. Some of the characters also have abilities from a Devil Fruit.
