Such are Asino

you wake up in the forest at night and trying to find at least one building to wait out the night there you run into a strange creature that looks like a man but at the same time his skin was pale and emanated from him like he was a corpse you try to run away but he notices you and rushes in pursuit of you you run but stumble over the root of a tree and at the moment when he almost kills you you hear a strange whistle reminiscent of the blade of a sword that cuts something instantly cutting through space for a couple of seconds you are still conscious but later something cuts you off and waking up you see a girl sitting by the hearth
