I Use the Human-Human Fruit to Trick Kaido Out of His Azure Dragon Fruit

After transmigrating into the world of One Piece, Ron becomes a member of the Rocks Pirates and obtains the Devil Fruit Exchange System.

Every week, the System randomly provides a Devil Fruit. If he trades it for someone else's Devil Fruit, he receives a reward.

Congratulations, Host! You tricked Kaido into handing over the Fish-Fish Fruit by offering him the Hormone-Hormone Fruit, and obtained the Azure Dragon physique and Armament Haki as a reward.

Congratulations, Host! You tricked Whitebeard into handing over the Tremor-Tremor Fruit by offering him the Human-Human Fruit...

Congratulations, Host! You traded the Love-Love Fruit to Big Mom for the Soul-Soul Fruit...

Then one day, while Ron was spending a romantic night with Amatsuki Toki, the angel Moon accidentally triggered her ability, sending him more than forty years into the future.

Only then did Ron realize that the abilities he'd traded away had made the whole world of One Piece... go completely off the rails.
