Somewhere between Konoha and Kumo, Sasuke's POV

After The Fourteen was sealed in me, Danzo formulated an elite team that is specialized to eliminate Kumo and Iwa. The team consists of Hinata, Kiba, Shino. Sakura, Kakashi, and me. We are on our way to annihilate Kumo by way of tree-jumping.

"Hey Sasuke! How does it feel to have another organism sealed inside of you?" asks Kiba.

"Hn." I answer. The truth is, I have never even attempted to make contact with the Fourteen tails. All of a sudden, I feel sleepy. As I make contact with the next branch, I collapse, and the world goes black. I wake up, hurting. What time is it? Where am I? I scan my surroundings, my guard up. I am in what appears to be a dark, cold, stone tunnel. I try to activate my Sharingan, but to no avail. I start to wander through the pitch black hallways of wherever I am. After at least half an hour wandering, I come to a massive clearing. The back wall is not in sight. I walk into the cold blackness of the unknown. I begin to see a gigantic silhouette slinking around in the shadow. I come to a cage with bars thicker than buildings. Suddenly, I see a boat-sized paw come crashing down on the bar. I jump back, startled. A massive sharingan shows itself just on the other side of the cage. This must be the fourteen tails.

"You have caused me quite the problem, little one. I see the pests from Konoha have sealed me within you. I am not happy with you." The deep voice of the black wolf grumbled."

"What is your name?" I ask. He must have a name after all.

"I was not given a name. Though some of my creators refer to me as Seikyo."

"Seikyo? Death? Why would they call you that?"

"Because I killed two full squads of ROOT. Which is mere child's play compared to what I'll do to you."

"I don't think so." I say, "I will harness you."

"Doubt it. You do not have your sharingan here. You have no power without sharingan." He answers cockily.

"Untrue. I still have my sword."

"A small sword is insignificant. I possess your father's mangekyou sharingan, giving me the ability to cast human jutsu as well as tailed beast jutsu. You will die."

"Unfortunately for you, I was given a device to harness you.While you were rambling, I placed it on you. It is a very small device that feed on your chakra and gives it to me. I now possess all your power. Have fun in here, fool." It is about the size of a softball. I have embedded it in your skin already. It harvests your chakra for my use, so I won't ever have to talk to you again.
