Assassin (Kakashi love story)

I dont know why either

Before we continued our journey I packed my everyday wear and wore what I did in the past. My ragged cloak and patched pants and rebadged myself up . Then we finally left to begin our journey again and no one said a word. It's been a while since I killed innocent people or even non-innocent people. But after yesterday I'm still heated and what better way to cool down when you have random "strong"enemy approaching you. He had a group of 50 men at least with him and I told my group to stand back. As that boy Naruto wanted to say something, Smellerbee put his hand out to stop him and calm him down. They look a little terrified until their leader said "C'mon men we can beat a little girl" so they charged at me. I moved at god-speed through the crowd, when I got to the other side where the leader was and I stopped. 5 seconds later heads started popping off, knees began to hit the floor and blood splatter everywhere, it was like a bloody field , trees and grass was now dyed red, and bodies all over the ground. The leader stood in terror and regret staring at the corpses on the ground then at me with blood stains on me. "I know your not the main leader so I want you send a message to him: I don't want to see your filthy face again and if you come near my friends again there will be more bloodshed". He still stood in terror then yell out the wrong words that just cost him his life "THATS BULL!!! " and within that second I snatched his head off and said in a evil but calm voice "Fine don't tell them" then squished his head and threw it next to the rest of the dead bodies. My group and Kakashi' group couldn't believe their eyes they also stood in terror. I wasn't yet satisfied but this will do for now.

_______ Kakashi POV _______

What kind of kekgenki, jutsu, or sorcery?!? I don't know what it is?!
I can feel pain and tensility from this. Then she turned her head towards us. My heart stopped for a moment but when I looked in her eyes I calmed down. I didn't see a killer, nor did I see blood lust I saw hurt , pain, no love , and a hint of no emotion some where in there but it's so scarce I actually had to squint. I felt like I needed to hug her. I don't know why either.
________Masters POV ______

After I turned around and went through all the corps pocket for money or something of importance, of course all there was , was stolen jewelry and money , meaning there should be a town near by. I started walking and the group followed after but kept a far distance , a very far distance . Once we got to the town I returned everything , received rewards and a free place to stay. Everyone went to drop their bags off , or just laid there quietly. I walked off up to a hill under a tree, then I sensed I was being followed. I turn around and put a kunai at the victims neck and I looked closer at who it was, I removed the weapon and kept walking as if nothing happen. I sat under tree, closed my eyes and then felt my head on a warm chest. I wanted to get up but I felt so safe and comfortable. I don't know why either.
