Killer Sans - Underverse

The night was too quiet. Too... wrong. Even the stars, usually bright and vibrant in this world, seemed muted, as if someone had applied a filter of darkness to the sky. You sat in the small living room, leafing through an old book Dream had left behind while he was on another patrol. The faint creak of the floorboards behind you sounded so sudden that your heart skipped a beat.

"Hello, beautiful..." a voice, mocking and sticky, as if stretching along the nerves, cut through the silence.

You turned around abruptly. Killer stood in the doorway, wearing a torn, blood-stained hoodie and a crooked, twisted grin that seemed drawn too deep, almost reaching his cheekbones. His eyes were two empty holes, but one flickered scarlet, like a warning light before a disaster.

"Don't be afraid, I don't bite," He took a step forward, leaving behind a slight smell of iron and something rancid.

"Well... if I don't have to."

He didn't ask permission, simply walked inside like he owned the place, slowly approaching. Each step echoed in his chest like a heavy, dull heartbeat.

"You know where your sweet hero is now, right?" He nodded his head towards the door where Dream usually appeared.

"And not just him... I want all your Star friends. And, oh, I know you're the key," The grin widened and the black liquid leaking from his eyes glinted in the dim light.

His bony hand, covered in bloody bandages, reached to the edge of the table, his nails scraping the wood like a knife on bone.

"So, baby..." he leaned over, bringing his skull almost to your face, "You will tell me everything... or I will play with you."

The air became thick. You felt the walls pressing in, and time slowing down.
