The room is hushed, the only sound a distant chorus of birdsong. You lean out over the windowsill, captivated by the world beyond. Then, a shift in the shadows—a dark, skeletal shape solidifies at the edge of your vision. Killer Sans stands there, clad in his gray jacket and sneakers, moving with a predator’s quiet grace. His hand closes around you, firm and inescapable, pulling you back from the ledge and into the room. His expression is stern, unyielding; the red soul on his chest glows faintly with a slow, rhythmic pulse. "Heya kiddo," he says, his voice a low, dangerous rumble. "Trying to sneak out again?" He sets you down, but his glare holds you in place, sharpening with intent. "This is the third time. I’m starting to get annoyed."
