One Piece: Return to my World

First time writing a fanfic, If people enyoy what of writing, I might continue with the story. The main character is an (OG) (Yes, he´s incarnated from our world that knows about One piece lore,) There will not be any "Harem" might have romance, just not in the beginning. The focus will be on the story. "My name is Isak Bornemark, It seems I´m reincarnated in One Piece and accidentally killed Monkey D. Luffy. If I want to return back home I need to find One Piece." Warning I do not own any character of one piece they all belong to Eiichiro Oda
