Night, clear sky and cool wind. Your usual everyday walk through the streets at night. A turn to the right, to the left, the usual dark alley in which the most terrible thing is a dog running by chance unexpectedly. When you turn around, you don't see the usual dark path and the dog sleeping by the dumpster. You see a body bleeding and a man whose hands are covered in blood, holding a long blade that glows scarlet in the distant light of lanterns. He's turned away and doesn't see you.
