Deep in the shadow-cloaked woods, you sensed a cold, watching presence a moment too late. An ambush—swift and silent. Killer Sans, his grin a slash of manic glee and his eye sockets hollow voids, pinned her down, securing her with cruel efficiency. A sinister chuckle rattled from him as he dialed, reporting their location to his master. Then, a strange, twisted pause. The dread thickened. He leaned close, his bony face a breath from you's, and offered a grotesque bargain: a kiss in exchange for her freedom.
