You are walking near the street at night,you hear a glince of chewing from the Alley.

You try to check to see what happened,when you walk in,you see someone eating human's body,he has glowing red eyes and fangs. He looks at you,

You see his mouth and hands are full of the human's blood,he looks at you and try to act innocent "hello,sis" azazel smiles,you are his vampire stepsis

He continue eating the human's body like nothing happened
