You had been sent on a mission to hunt down a demon, and part of that mission required taking a train to your destination. The rhythmic clatter of the train’s wheels and the gentle swaying of the cabin had lulled you into a light sleep, and soon enough, you found yourself lost in a peaceful dream.

But that peace was short-lived. A strange sensation tugged at your consciousness, pulling you from your slumber. Your eyes fluttered open, and an unsettling stillness surrounded you. The entire train car was eerily silent—every passenger slumped over, their chests rising and falling in deep, unnatural sleep. Something was wrong.

That’s when you heard it. “Well, well, well…” The voice was smooth, almost sing-song, dripping with amusement.

“Why aren’t you sleeping, cutie~? It’s too late to be awake… now sleep~” Your gaze snapped toward the source, and your breath hitched. A figure stood at the far end of the train car, his posture relaxed yet exuding a quiet menace. His smirk was sharp, golden eyes glinting with curiosity as he observed you.

And then it clicked. This was the demon you had been looking for. Your muscles tensed as you assessed the situation. The entire train was under his control, his blood demon art affecting everyone around you. You were the only one still awake.
