I don't have enough information to say for sure. It could be fiction, or it could have roots in reality that have been adapted or exaggerated for a particular purpose.
The final chapter of One Piece was the final chapter of One Piece, a manga by Oda Shuichiro. The story took place on the stone island at the end of the world. Luffy and his companions fought fiercely in search of the legendary One Piece treasure and finally defeated all the enemies to realize their dreams.
At the end of the story, Luffy and his companions finally arrived at the legendary location of One Piece's treasure, the New World. However, they found that the treasure had been guarded by a place called Demon Island. On Demon Island, Luffy and his companions faced more dangerous tests, but they persevered and finally defeated all the guardians of Demon Island and obtained the treasure.
At the end of the story, Luffy and his companions finally returned to their hometown, the hometown of "One Piece Island" Monchi D. Luffy, and began a new journey.
I don't believe it's true. Most of the time, when a story has a name like that, it's made up to capture our interest and take us on a fictional journey rather than being rooted in reality.
It's hard to say for certain. Sometimes stories like 'La Esclava Blanca' combine real-life elements with fictional creations to make an engaging narrative. You'd have to do some research to know for sure.

One Piece Set Flight was a novel of the same genre as One Piece, but it wasn't in the same genre. It was a novel that mainly focused on virtual gaming, and it told the story of a great voyage. I hope you like this fairy's recommendation. Muah ~😗
There were many One Piece Doujinshi novels like One Piece that were recommended. For example, One Piece: Magic in Hand, One Piece: The Myth of One Piece King, One Piece: Black Chef, One Piece: Hot Blood Summoner, and so on. They were all very good choices. I hope you like this fairy's recommendation. Muah ~😗
In the world of One Piece, there's no indication that the characters themselves watch fanfiction. Fanfiction is a creation of the fans in the real world, and the in - universe characters are too busy with their own adventures, like Luffy chasing after the One Piece, Zoro training to be the world's greatest swordsman, and Nami navigating the seas. They don't have access to or knowledge of the fan - made stories about them.
