These novels would usually be adapted from the original novel, adding new storylines and characters to form their own unique Doujinshi world.

One Piece Doujinshi was a fictional cultural product that readers could read according to their preferences. However, we should also remember that the original work is a fictional story that has nothing to do with the real world. The readers should not confuse the plot of the novel with reality.
