One Piece: Fūjin

Shun a boy from East Blue, will embark on a journey of revenge, getting on the way a legendary fruit that was lost long ago, what will he do with this power? Will he become a hero or a demon?

PS: The protagonist is not reincarnated or anything like that, he is a human who belongs to the world of One Piece, only created by me.
As for the devil fruit, I will only say that it can control the air.
