One Piece: an Ordinary Pirate

I want to write a One Piece adventure that is truly my own. Real and interesting, I may not be able to do these, I just want to write... Every time I watch Luffy shout "I am the man who became the Pirate King", I can't help but wonder, will he still have such a smile when he really reaches the top? Did he really not understand when he did things that ordinary people would not dare to break? What will happen to him when he becomes the Pirate Queen? Should he remain the same as before, disappear, or continue his adventure? But until then, will there be anywhere to take risks? Therefore, I want to write about an ordinary person. He may not know how to sail, cook, repair ships, snipe, or play music, but he has the ability to protect himself. He will always accompany Luffy until the end of the world... CP will be Luffy, but more like two tacit partners.
