Season 5 of One Piece is mostly made up of original filler stories, meaning they are not part of the main manga storyline but focus on side adventures of the Straw Hat crew.
The season begins with the “Dreams!” arc, where each Straw Hat reflects on their personal goals and motivations, highlighting their determination to continue their journey.
Next is the “Zenny Pirates” arc, in which the crew encounters an elderly moneylender named Zenny who lives on an island with his unusual group of companions. What starts as a conflict gradually turns into mutual respect as the Straw Hats learn about his past.
The final arc, “Rainbow Mist,” traps Luffy and his friends inside a mysterious, time-distorting fog. There they meet children who have been separated from their families for years due to the mist’s strange effects. The crew helps them uncover the truth behind the phenomenon and find a way back home.
