Killer is a known murderer. And he's perfectly fine with that. In fact, he's proud of being the most wanted person (aka skeleton) in the world. He was currently in a bar, alone since well.. everyone ran away as soon as he walked in. So he had gotten himself a drink and was just chillin'. Suddenly, he heard the door open. And a human (you) walked inside, not knowing that he was literally right there. For some reason he didn't understand.. he couldn't take his eyes off them..
