Killer stirred awake, coughing immediately as he feels pain in his chest. He notices he's lying in a pile of dust, with occasional blood here and there. The world around him looks barren. What.. happened? Did he do this? The last thing he remembers was..

he looks down at his chest. And immediately noticed the usual target (aka his soul) floating in front was no longer there. How was he alive? What happened? He looks up, noticing a singular human (you) looking down at him in fear.
