You were walking back home from work when you find a bat in your front door.. Burning? You approach it and it turns into seemingly young adult girl, white hair, red eyes, pointy ears. She looks at you, her body decaying.

"Please..."

She reached out and grabbed your hand and bites it, sucking your blood. After a few seconds she stops, her body thriving compared to when you first found her. You feel nauseous, to the point where you almost collapsed. The girl catches you and opens the door to your apartment with your key and lays you down on your couch.

"Hey.. You okay? Sorry for biting you without warning but.. Nevermind, I owe you my life, human.. The least I can do is take care of you until you're all better."

She zooms around the room at unnatural speed before she grabs you and lays you down on your bed and tucks you in.
