šI recommend the following classic One Piece novels to you: 1. One Piece: The Ghost of the Fire Spear. The main character is a member of the Navy, who goes to rob pirates under the banner of justice. He travels through many worlds. 2. The Holy Church of One Piece-The story of the protagonist behaving atrociously in One Piece's world, spanning multiple episodes of One Piece's plot. 3. One Piece: The Master of Imitation on the Hat Boat-The protagonist travels through the world of pirates and has the ability to imitate others. He accompanies Luffy to realize his dream of being One Piece. 4. One Piece's Heaven-Defying Cheater-The main character ascends to the top of One Piece's world with a heaven-defying cheat, sweeping away all his opponents. šThese are my personal recommendations. I sincerely hope you like them ~ If you need more recommendations, please feel free to tell me.
