Street Justice

I jumped up from my cold, hard mattress, wide awake from whatever hell my mind made for me in my sleep.
It took a few breaths to regain my calm. The sweat dropped my body temperature down, as my apartment was already freezing. Every nerve ending was alive with information, brightening my mind with the sobering sensation of cold.
I looked outside my window and saw the sun setting. I knew it was time to go out and work. I dressed simple. I always had to dress as simply and as nondescript as possible. It just makes the hunt that much easier.

I walked down the street, avoiding the faint orange glow that spills from the lampposts and dully illuminates the cracks and spit on pavement. It was early enough into the night when I found one of them. It seemed like they came out earlier and earlier each night.
So there I stood, watching one of them grabbing a person, some girl with a short skirt... to someone walking by, that's all they would see. But I knew. I fucking knew.
Refusing to let her be consumed by him, I charged and dove, tackling him down. I was immediately disoriented as the bastard pulled us through the wall. I could feel my whole body tensing as we phased through matter. It's like a strong static shock coursing through every fiber of muscle, every bone, every tendon.
We fell for what seemed to be a long time, each one of us struggling to gain ground. The problem was that there was no ground to gain. Finally, he could hold no longer and we landed hard on some tiled floor, at least a few floors below the ground in some building. The sharp pain in my spine and bright white pain in the back of my skull told me that I was the one who had landed on the bottom.
I felt a weight lift off my chest, only to find another swing into my jaw, brightening that hot white pain and spreading it to the front of my head. The blow forced me to roll onto my side. I held my jaw with my left hand and would have continued to nurse the swelling spot, had I not heard footsteps circling me. I bounced to my feet and swung to where the sound was, feeling my knuckles bury themselves into a neck. It knocked him backwards, but he saved himself from a fall by using the momentum to spin around and pounce towards me. I had anticipated this and lowered myself to catch him. I grabbed him by his shirt and threw him against a pillar in the middle of the hallway we found ourselves in. The sterile tube lights that lit the hallway gave me a better look at my opponent. He was thin, very pale and had dark hair. His eyes were as hollow and dark as they all were. I reminded myself not to gaze into those windows, because they were gaping black holes, waiting to consume any and all life that they could see.
Realizing that he wasn't going to feast on me, he swung at me. I blocked and parried his fist with my arm by instinct and then swung with my left, only to find his hit my chest first. I slammed my forehead into his face, letting that bright, painful light fill up my skull for the briefest moment. A split second later, I opened my eyes to see him recoiling with blood gushing out of his nose.
Relentlessness is the only way to win against them.
So I hit his face again with my fist. Then again with my head. And again, and again, and again. He fell to the floor. And as he fell, so did my knee into his chest. His head lifted up in pain, and I slammed it back down with my right fist. Then I swung at it with my left. Then my right. Then my left.
After a while, the gurgling stopped. A short while later, so did the twitching. I was glad, because my knuckles were getting sore and my leg was getting pins and needles from staying in the the same spot for so long. Satisfied that he was dead enough for now, I pulled out my flask and doused the bloody corpse with the contents in it, then lit a match and walked away. Normally I would've stayed to make sure that the entire body was consumed by fire and nothing but ash remained, but there was a victim up there. I had never caught one in the middle of the act before, and if she was still alive, I had to find her.

Sure enough, I found her shivering in the same spot I had left her.
"It's alright, he's gone..."
She still shivered in the corner like a frightened rabbit. I put my hand on her arm. Her head snapped towards me and she began to utter odd sounds while shaking and crying.
My heart sank as I realized that instead of saving her, I condemned her mind to being nothing but a shattered and fragmented version of it's former self. There were only bits and pieces left to process the information that the nerves were feeding her, and probably even less to sift through the thoughts and try to make sense of the world.
With heavy and tired arms, I grabbed her head and twisted as hard as I could. It was enough to snap, and I left her on the ground.

I will clean the entire fucking city of this vermin. One by one, I will hunt them down, kill them and burn them. I will not stop for a single fucking night until every one of those fucking bastards are wiped from this earth like excrement from a boot.
