In World of One piece with Hanma bloodline

Sorry in advance for my bad english and grammar, english is not my first language, and it's my first time to write, it's just for my fun cause I can't get this idea in my head so yeah thats it. Onepiece and baki story and characters are not owned by me except the OC in my fanfic, the cover is not mine, if it yours message me if you want it to be removed. A normal human who got trucked kun meet a lazy looking gandalf and got reincarnated in a world of one piece as a older twin of Rocks D. Xebec with Hanma bloodline.
