One Piece - The First Mate

Journey of one piece with my OC Kaiser D Jason added to straw hats where Luffy is not exactly started out as idiot. Adding more depth to both Luffy and Jason along with some romance in the way. Paring is going to be Jason x Harem and Luffy x Harem. I do not own one piece or its characters. This is just a fan fiction based it, I respect oda sensei on giving the world this master piece. Kudos and cheers. Also, Thank you Lionheart021 who gave permission to use some of his fanfic ideas.
