One Piece: The Strongest Possession

Transmigrating into the world of One Piece, he unexpectedly becomes Roger's younger brother.

It's hard to imagine that Roger, already in his fifties, could have a younger brother in his teens.

But while his older brother becomes the Pirate King, the younger one has no talent at all.

Luckily, at sixteen, he discovers that he has a Possession System.

Possess Ip Man and gain a grandmaster's state of mind; possess Gai Nie and gain the Flying Sword Technique from One Hundred Paces; possess Li Xiaoyao and gain the Shushan Sword Arts.

You think those are the only ones he can possess? Think again!

Pain, Itachi, Ichigo Kurosaki: as long as he has money, he can possess any spirit.

This is a world where money can make even ghosts work for you!
