Vampires bite.

A man walks down a corridor. He clutches at his stomach and his mouth, a look of crazed hunger flickers through his eyes. He reaches a door at the end of the corridor. A steel door with flecks of rust on it, he opened the door with a shaky hand and stepped through.  He looked around the room. It was barren. Stains on the ceiling and the walls, dark corners, and no furniture. There was a movement in one of the corners. The man walked forwards, his dark coat done tight around him. The steel door slammed shut. The man spun round and almost fell. A shape emerged from one of the corners. It was a small girl, with scarlet hair, wearing a pink dress and with wings on her back. The man looked at her wings and decided that they were fake. He looked at her neck and imagined the blood pumping through her veins. The girl walked forwards, the chain around her ankle rattling along the floor. The man muttered something that sounded like "full body smoke," and disappeared into a cloud of black smoke. The girl looked around, trying to see where he had gone. The man materialised behind her and bit her neck.
"That won't work."
"Huh?" The comment took the vampire by surprise.
"I said that it won't work. I'm also a vampire." The girl sounded annoyed at the man. "My name is Lumiria Scarlata...now get off my neck"
The man released and stepped back "Oh...sorry bout that, I'm Karaid Korad...I'm a half vampire...Nice to meet you."He offered his hand for the girl to shake. She looked at it and then slashed it with her nails, which had suddenly turned into talons.
"OW!" Karaid exclaimed pulling his hand away. "That hurt!" He watched as tendrils of flesh sprung across his hand as it healed itself. "What the hell was that for?"
"You bite me, I scratch you." Lumiria said nastily. Karaid muttered something under his breath, the door suddenly opened and closed as a man cautiously walked through.
"Can I" Karaid asked hopefully, his stomach feeling as if it was twisting up into a small ball.
"Knock yourself out" Lumiria said, not looking at him.
"Thanks" Karaid said. He sprang onto the man and sank his teeth in deep. He drank deep and greedily, and when he pulled his head up, the blood dripping from his mouth, he had to put all of his weight on the wound to stop the blood from pouring out from the gaping wound that he had created. He took out some glass bottles and pressed them onto the wound. The red liquid slowly filled each bottle, after they were full, he clamped is teeth back on and drank greedily, until the man was dry of blood. Karaid stood up, panting."Thanks...I hadn't drunk in three months..."
"I meant knock yourself out...as in run into a wall." Lumiria snapped, unfolding her wings and flying towards her corner.
"Hey, how do I get out of here?" Karaid was inspecting the door, there was no way to open it from the inside.
"you can't...I guess that means that your stuck here...want to play a game with me?" The girl looked hopeful, Karaid looked over his shoulder at the girl, 'she must be lonely down here' he thought to himself. "What would the game be?"
"And then there were none!!!" The girl shouted happily.
"sure, sure" Karaid said absent-mindedly, trying to work out how to get out.
There was a sound of knives being drawn from sheaths, Karaid slowly turned around and saw Lumiria's nails had grown longer, she was holding them in front of her face. she slashed them through the air and smiled, looking insane and scary.
"Shit."Karaid said, just before Lumiria flew into the air and dive-bombed him.
