I think you shouldn't let other characters steal importance from the protagonist, that is, the fanfic is about a person reincarnated in another world similar (not the same) to the 'One Piece' anime. If the author or readers wanted to read or watch about Luffy and his crew, the best and most fun would be to watch the anime or the manga. The manga and anime are reviewed by a group of professionals, the writing quality will be better than that of a fanfic, so it wouldn't make sense to read a fanfic that copy-pastes (with errors) the story of Luffy and his crew. Having said all that, I have two big doubts: is the story about Luffy and his crew? Will the reincarnated person from 'our' world become a slave to the plot? đ€
