He eat a devil fruit but don't even begin to explain what fruit it is.His new body is 4 years old but he never feel strange about it. He never realise he was in another world until he met the pirates.
Love the idea of your story. Making a dark mature fic of one piece. But there is no transition between chapter 1 and 2. He get a devil fruit out of the blue (pirate know what it is and should have protected it).
