I'm Already One of the Five Emperors! The System That Makes Me Stronger Arrives to Everyone's Shock

[One Piece Fan Fiction] [Transmigration] [A System That Grows Stronger by Absorbing Shock] [Fifth Emperor] [Powering Up] [Building a Faction] [Shocking Nami, Luffy, Zoro, Sanji, Robin, Law, Kid, Doflamingo, and more as the Fifth Emperor]

Years after transmigrating into the One Piece world, Ethan is known as one of the Five Emperors of the Sea.

But Ethan knows full well that he is nowhere near as strong as the actual Four Emperors.

Then he gets a System that lets him grow stronger by absorbing other people's shock.

With the System, Ethan can exchange for [Supreme King Haki Coating], [Nika Fruit (with no side effects)], [Immortality], [Time Stop], and more...

From then on, Ethan begins to shock the entire world.

Nami: No way! How could the famous Fifth Emperor be in the East Blue?

Luffy: Ow, ow... Why does your punch hurt me?

Sengoku: I thought you weren't worthy of being called a Fifth Emperor, but it seems I was wrong.

Doflamingo: This monster is even more monstrous than Kaido.

Dragon: He can lead our revolution.

Kong: This guy will be the greatest enemy our World Government has ever faced.

Red-Haired Shanks: He can control the fate of this world.
