Naruto: Akatsuki from the Start, Fists Speak Louder Than Understanding

After dying in his previous life, Karp transmigrates into the Hokage world as a baby and obtains the Karp Template from the One Piece world.

During the war in the Land of Rain, young Karp is rescued by Yahiko, Nagato, and Konan.

From then on, the four become companions who have faced life and death together.

Yahiko establishes the Akatsuki, hoping to end the war in the Land of Rain through understanding and communication.

But Karp never believes that mere words can change the shinobi world.

When faced with people who refuse to listen to reason, a fist is the most direct answer.
