One Piece: Uchiha Style

Disclaimer - I do not own the characters, plot or anything of the anime universes/franchises used throughout this fanfiction. All credits go to creators and publishers for creating these wonderful Mangas/Animes. An orphan otaku dies in a car accident and is confirmed brain-dead, because of this the doctors decide to transplant his heart into another guy in order to ensure at least one person survives... What happens when the otaku is given a chance at reincarnation? P.S - First time writing a novel and constructive criticism would help a lot so that my writing can get better looking into the future.
