Disclaimer: I don't own Harry Potter or Vampire Knight.

Note: Hey guys! Sorry it's been so long. No excuses, I just lost interest in and then forgot this story. I hope to write at least two more chapters by the end of November, though.

Warning: spoilers, Yuki bashing (not Kaname bashing, or at least not much)

Enjoy!

Hayden stood awkwardly as Ichijo Takuma, Vice President of the Night Class, introduced her to her new classmates.

Being eyed by a few dozen vampires (of various ranks) wasn't a comfortable feeling, no matter if you were a vampire yourself.

"Hello." She greeted the room at large. Most of them nodded at her.

"A Guardian in the Night Class?" Senri Shiki mused thoughtfully. "Interesting."

He didn't say anything more.

Hayden had a feeling that she'd seen him before (and the orange-haired girl beside him, actually).

As if sensing her thoughts, Ichijo muttered (too quietly for the rest of the vampires to hear). "Senri and Rima work as models during the day."

'Oh.' Hayden thought. 'That would explain it.'

Then: 'Do they ever have time to sleep?'

Maybe she would ask them. Right now they looked tired, but that might be because it was late in the morning, when a vampire would usually be sleeping.

Kuran Kaname, the President of the Night Class, had wanted her to be introduced to the other students as soon as possible so they didn't accidentally attack her thinking that she was an intruder.

Considering the academy had been attacked by rogue vampires and the leader of the Hunter's Association recently, Hayden thought that this was a reasonable precaution.

But that didn't mean that she wasn't sympathetic for the people who had been pulled from their beds.

The only Night Class student who wasn't there was Kaname's younger sister and fiancé, Yuki.

The Headmaster's adopted daughter whose vampire side had been sealed up until recently, only for her to be awakened and find out that she had been betrothed since birth to Kaname, who she had admired and been crushing on for years.

From the expression a few of the other Night Class students made when Kaname told them that Yuki was still sleeping, they weren't particularly bothered that she wasn't there.

Hayden wondered at that, knowing that purebloods were basically royalty, even if technically they were now ruled by the Vampire Council as opposed to the pureblood monarchy.

Huh. If the purebloods hadn't given up their power, Kuran Kaname would have been their king, and with Yuki betrothed to him, she would have become a queen.

Knowing that only made Hayden more intrigued by the dislike the others seemed to have for the former human.

What had she done to turn them against her?

Hayden waited until most of the Night Class students had wandered out of the room before turning to Aido, who had been flirting with her practically non-stop after introductions were made.

"You know, you don't need to pretend." She told him softly.

The ice user's blue eyes widened, and he ran a hand through his fashionably messy blonde locks.

"I don't know what you mean." He said with a charming grin.

Hayden gave him an unimpressed look, causing the boy to falter slightly.

"Seriously, you can drop the act around me." She told him. "You're a good actor, but no way am I dense enough not to notice that your flirting is an act, or at least after seeing you look at Wakaba-san when her and Kiryuu-san dropped me off."

Aido's eyes widened in shock, before he closed his eyes, body slumping.

"Am I really that obvious?" he asked, resigned.

Hayden bit her lip thoughtfully. "Not really. I'm just perceptive. If it helps, she seemed to be glancing at you when she thought no one was paying attention."

The blonde's heart clenched painfully.

"She looked a bit sad, though." Hayden continued. "…Did something happen between you?"

Aido caught the unasked question of whether or not he had hurt the human girl somehow, and grimaced. "Nothing like that. She knows I like her, and she's told me that she feels the same…"

"But…" Hayden urged.

"But she doesn't want to be in a relationship with someone who will age that much slower than she does, and she want to be turned into a vampire, either."

Hayden's heart panged as she observed his heartbroken expression.

He really loved this girl, even if he didn't realize that his feelings were quite that deep.

"Maybe…" Hayden paused, unsure of how he would react to her idea.

"What?" he asked immediately, hope blossoming in his chest.

Hayden bit her lip again. "Well…Headmaster Cross mentioned to me that you're a science prodigy."

Aido confirmed this. "Mostly chemistry."

"Maybe you can find a cure for your vampirism?" she suggested hesitantly. "Or at least something to speed up your aging?"

Contrary to Hayden's worries, Aido's eyes brightened at the idea, and he beamed.

"That's perfect!" he enthused, ideas already running through his mind. "But it's never been done before."

Hayden eyed the older teen, eyes narrowed, before she made a decision.

"If you go with the 'speed up your aging' option, I have something that you can analyze and base your formula on." She offered.

Aido froze, turning to look at her. "What do you mean?"

Hayden blinked. "You can't speak a word of what I'm about to tell you."

The blonde froze at her tone, before giving her a serious nod.

"I'm a witch." Hayden said simply, not bothering to beat around the bush. Vampires were already aware of magic, anyway.

Aido's eyes widened (that seemed to be happening a lot today, he mused.)

After a moment, he muttered. "That's…pretty rare for a vampire."

He could tell that there was more to it, but didn't ask, which Hayden appreciated.

"Yeah." Hayden agreed. "Anyway, in the wizarding world there's a potion that de-ages a person. It's not long-term, and I don't know how it would effect a vampire, but-"

"But it's a start." Aido finished, smiling genuinely for the first time in days as a determination overtook him. "And in the meantime I'll research a cure, too."

Glancing at the blue-eyed boy, Hayden had the strangest feeling that she had just made a friend for life.

Please review! :)

Note: Sayori and Aido is CANON. They got married, at least according to the Vampire Knight Wikipedia, despite it also saying that Sayori had a fiancé due to an arranged marriage. But she really did refuse to be turned, and died before he did. He really had been working on something to cure his vampirism. But now with Hayden's help and magical knowledge, maybe he'll be able to find a cure before that happens…and yes, he is actually a science genius. Remember those two scientists in the anime who were trying to talk him into working for them?
