A/N: Just to clear out any and all misunderstandings regarding any superpowers our OC/MC would be getting- There would be no system or any inborn superpowers, except maybe a better-than-normal memory and faster-sharper mind and processing power.
OC/MC will only gain some knowledge and characteristics from the soul that died, other than that, he is a newborn pure soul, hence he will act as such.
Also, after reading many ff of one piece on this site, I have seen such comments as:
-Why dumb author insert the OC in the straw hats crew
-Why is the author such a pussy that he can't adventure all alone taking what is originally the straw hat crew's things; like Zoro's swords from Lougetown.
-Add harem members
-Kill willy-nilly
-Take devil fruit/Don't take devil fruit
Here's the answer to all that:
-NO HAREM.
-NO ANIMALISTIC KILLING.
-My story's OC would join the crew; terms and conditions applied
-Devil fruit or not will depend as the story progresses; for now, though, I am of the mind to say no to devil fruits
-No stealing the original crew's things; OC will get his own stuff.
-No adventuring alone, as it will create too many OCs to flesh out later on.
-Once again, NO HAREM.
