One Piece: Adventure of Leo

A young man wakes up on an unknown island after finding out he is in one piece world, he will try to survive and live his second life the way he wants it with a system that is surprising help full.
---------------------------------------------------------------------------
I just want to point out that the choice MC makes in the profession will only affect the mission given by the system.

If the MC chooses a Morganeer-type pirate, then he will get a mission to raid an Island or some other things.

Hope this will clean up the confusion the mc is going to be a hero.
