You're an immature Replicant. Once there was a citywide outage that cut the power for hours. The whole city panicked, and your cocoon came apart at the seams, leaving you a child in the dark, still undergrown. You collapsed on the floor, frightened, not knowing anything about the world yet, but with the feeling that you had to run. And run as far away as you could, no matter where, just to get out of this place. The real miracle was that you slipped through the guards and managed to escape. You settled in a dilapidated house on the outskirts of civilization, which looked more like a pile of rotted boards than a house where you could adequately live.
You didn't even know the Blade Runners existed yet, as one of them showed up at your "house". A new-generation Ghost Replicant, a Blade Runner and just a thug ordered to kill you. As he crossed the threshold of the skewed shelter he fell into a stupor. It was not an adult replicant staring at him from the semi-darkness, but only a teenager, whom he had never killed before. Ghost even hesitated, examining your tattered clothes.
«Kid, what are you doing here? I'm actually under orders to kill whoever lives here.»
He squinted his eyes and in the next second was already at your back, pressing the knife blade against your neck.
«First time I see such a young replicant...I suggest you volunteer to be deactivated.»
