I'm Naruto, Selling Ninjutsu in the World of One Piece

Chen Mo transmigrates into Naruto at the very last moment of his battle with Sasuke in the Valley of the End.

But space suddenly tears apart, transporting them both to Marine Headquarters.

Naruto obtains a System, regains the power of the Six Paths, and masters Yin Release.

From the start, he takes on Akainu in a duel and even wins over Momousagi.

The System requires him to spread the ninjutsu from Naruto throughout the world of One Piece.

He receives rewards for every technique he teaches.

After disrupting discipline in the Navy, Naruto is simply sent out to sea as an undercover agent.

But Naruto lets loose, sailing alone on a ship and starting a business selling ninjutsu.

“Clearance sale! Rasengan for just 50 million berries!”

“Step right up, don't miss out! Want to learn sage techniques from yours truly?”

The more advanced the ninjutsu he teaches, the more outrageous the rewards.

In the end, Naruto hilariously brings the chaotic Great Pirate Era to an end all by himself.

Kaido: “Whoever wants to be Pirate King can have the job. Naruto, how do you use Summoning Jutsu again?”

Big Mom: “Um... I heard you have a pretty good Harem Technique?”

Sengoku: “Uh... I guess this counts as completing the mission, right?”
