This is my first fanfic, so please be nice.

Summary: Zero and Kaname have always been similar, with similar traumatic experiences and pasts. Both are drawn to one another, though they loath to admit it. As they both know the biggest difference Zero is a level D, who will one day fall to level E, while Kaname is a pureblood. These facts will constantly threaten any possible relationship they have, as enemies, friends or perhaps something more…However a new Day Class student seems to have hidden secrets which concern Zero, and when the truth is revealed what will it change?

This will be a Yaoi fic, which is M/M with ZeroXKaname and vice versa. There will possibly be some TakumaXShiki as well. Some possible other pairings but Kaname/Zero Zero/Kaname will be the main one. This will mostly be Romance, Drama and possibly Humour.

A.n. This is slightly AU as Ichiru died when Shizuka was killed and Zero has not got any of her blood– so there is nothing to stop Zero falling to level E. Kaname hasn't yet given Zero any blood and Yuki is still human. Also Rido hasn't yet attacked the academy.

Disclaimer: I do not own Vampire Knight or its characters, they are the work of Matsuri Hino, I am just borrowing them for the purpose of this fic. All I own are my own characters and the plot line.

Pureblood Powers

Prologue

Large imposing gates stretch upwards into the dark night sky, backed by darkened woodland, with not a building in sight. Cross Academy. Home to both Day and Night classes. Unsure if this was the correct location a small brunette, in a large dark cloak, stood outside the gates. It seemed completely unlike how she had ever imagined any school to be. Yet it was definitely the address on the letter, she double checked it, yes it was. Sighing and feeling slightly intimidated by the imposing gates she pressed the intercom. It crackled to life:

~Yes, and who is this?

~ This is Cross Academy isn't it? May I please speak to the headmaster?

~ Speaking

~ This is …

What should she say? How did she refer to herself? Even Headmaster Cross didn't know her name, he had addressed the letter To Whom It May Concern, and so what should she call herself?

~ Are you still there? Who are you?

~Headmaster, I received your letter and so I came as quickly as I could.

~Letter? Are you…?

~Kiryu-san, I guess…however it's been along time since I was called that, Headmaster, but yes I guess that is my name.

~ You'd better come in, how could I refuse, I contacted you!

With that the intercom went dead and the gates slowly swung open, I hope this isn't a mistake she thought inwardly before, walking up the driveway, going on guess work, and hoping, that the driveway would lead straight to the headmaster's house. Luckily it did and the girl was soon leaning on the bell of the door. This was soon opened by a light brown haired man, Headmaster Cross her brain supplied.

"Is that really you Kiryu-san, wait a minute…Juri?"

"OF COUSRE I AM NOT JURI…however much I might look like her. I am Alanna, and I received your letter so I came… as it was I who you addressed that letter too."

Kaien looked again, yes on second glance, her hair was to light to be Juri's and her eyes were hazel not dark brown.

"Alanna, so that's what you're called. You know I didn't even know if that letter would find it's intended recipient… or if that recipient was still alive. But I had to try."

"I wrote you this letter…to explain everything. So if you want Kaien Cross…"

She held out a letter with a slightly trembling hand, which Kaien quickly took from the girl.

A short while later

Kaien Cross, headmaster of Cross Academy, looked at the letter in his hands, the letter that Alanna had given him. He wasn't sure whether to believe or disbelieve Alanna, if he disbelieved her and what she said was true it would mean her death and the eventual death or at least imprisonment of the majority of vampires, Kaname and Zero included. However if he believed her and she was lying then who knows how much trouble she could cause. Though he wasn't sure what she would have to gain from lying about this, and if it was a lie it was certainly an elaborate one. Therefore he had a very important decision to make.

Also despite her earlier nervousness, it was now him which felt unnerved as she simply stood watching him, silently, with large unblinking violet tinted hazel eyes. Her brunet curls flowing freely down her back, oh why did she have to look so similar to Juri? She looked up as if sensing his unease and spoke to him properly for the first time.

"Kaien – Headmaster Cross – please, I know that you are worried about what may happen but I promise I will do nothing to harm the ones I seek. I only have their best interests at heart! I will not harm either Yuki or Zero, and I promise not to uncover the secrets of the Night class, why would I? I only wish to see how Yuki, and Kaname, are fairing and see if Zero is who I think he may be. If he is not then I will leave, I do not wish endanger the fragile peace that resides here."

"You said you will leave if he is not who you think he is. So what if he is, what if he is the one you seek? Then what will you do?"

"If he is, then I will break the spell. You know that I will have to do that if I wish to live, but I will tell you this, if I think breaking the spell will cause more pain and harm I will not break the spell and I will leave. Remember however if I leave I can not and will never be able to return. The only way to ensure my survival is to break the spell, but if I fear it could kill Zero I won't break it. I will not kill Zero…even if that means that the spell never gets broken…I could never kill Zero"

"It would normally be against my better judgment, however some part of me seems to know this is right, and so I will allow you to join the Day class, but be careful. Do not reveal yourself under any circumstances or until you have determined that Zero is the one you are looking for, or we will have a serious problem, and if you harm either Day or Night class you will have to leave…you know that …don't you?"

"Your decision lightens my very soul and you can rest assured that I would never wish harm on a fellow creature, and will do my best to not to harm the Day or Night classes."

"Very well class begins next term, which is just 2 days away, tomorrow you can meet Yuki and Zero, as they are the school guardians and so will need to meet you. I think for the time being it would be best to act as a normal school girl, and keep this conversation between us until the time is right. Alanna Kinoto-san."

"I agree with that decision and thank you greatly. Headmaster Cross"

End of prologue

That's the end of the prologue. I am sorry if that didn't really make any sense, however it was all needed for the story and more will become clear in later chapters. (if you want me to continue). I plan to bring in some ZXK action soon but maybe not for a few chapters. Please Review! XD
