(Authors Note: Yuki is kind of out of character. In this one, she's more head strong.)

"Wait, what?" Zero exclaimed

"You heard me. We are getting a new student guardian. Her father used to be a hunter just like me," Kaien explained.

"Before you were going on and on about how we can't afford anyone to know about the vampires," Zero hissed, slamming his fist on Kaien's desk, causing his white hair to cascade over his eyes.

"Yes, but she already knows of vampires. That is exactly why her father signed her up."

"You don't just sign up for this," Zero growled.

"And why not," Kaien argued. Zero glared daggers at him, then stormed out of the room. Things had been tense around here, and this wasn't helping. Zero feeds upon me in secret. In order to prevent Zero from running away, I promised him that I would be his ally, and that I would kill him if he became a Level E vampire. I know that Kaname knows about it, but I honestly don't care. I just don't know if I would be about to do that. To kill the one person I care about most in the world? I know I promised him, but I don't know if I could do it.

"Would you like to be the one, my sweet daughter, to give her the tour," Kaien asked, batting his eye lashes.

I straitened myself up, "No sir. I have fallen behind in my studies. Let Zero do it. This way he'll have to get to know her" And this way I can avoid him. But I didn't say that out loud

His eyes watered, "You have grown up so fast. Come give daddy a hug," he began to say, but I was already half way out the door.

Walking down the hall, I used the moon light flooding though the window to guide me. I walked out on to the ground of the school and took my usual patrol. Most people would have found walking around in the dead of night frightening. I found it comforting. After a while, I heard some shouts. They were coming from fountain. I broke out into a jog. As I got closer the voices got louder and louder.

"Stop right there," I yelled, as I ran into the clearing. Instead of being some Day Class girls, it was just one girl. And Zero.

"Hi. You must be professor crosses daughter. I'm Anna," she said in an English accent. She was average height, with jet black hair and bright green eyes. "I was just telling your friend," she gestured to Zero, "That I am at the right place. I'm trying to find you father so that he can show me around here."

"He's supposed to show you around," I told her. Zero's eyes widened.

"This one? He's a bit of an ass, but I won't mind," she turned to him, "Shall we?"

Zero glared at me before ushering her along. For some reason, I felt a pang of jealousy. I shook my head, turned around, and continued my patrol. But for some reason, I wasn't able to get the feeling that this girl was going to change everything, and not in a good way.

This is the prologue. I hoped you enjoyed. I will be posting new chapters weekly, and they will be way longer. Please R&R.
