Zero's eyes narrowed subconsciously at the girl who walked in behind his former mentor. He was, he could admit, a bit curious as to how on earth the girl was a witch as well as a vampire. Like he'd thought earlier, there was no record of a Level B ever being able to practice that kind of magic. For a moment he had doubted that Cross was telling the truth, but one whiff of the girl's scent and 'taste' of her aura and he could feel the power running through her.

Once his initial surprise passed, he got a closer look at the girl. She was about the same size as Yuki had been (he refused to think 'is', because she was practically dead to him now), though she was more filled out and clearly had some muscle tone.

Her hair was pure black, similar to Yagari sensei, and her eyes were the most vivid color of green that he had ever seen, as jewel-like as that creepy cheery vampire, but brighter. She had the vampire trademark pale ivory skin, and he could just barely make out the faint scars scattered across the skin that was visible.

His brows furrowed slightly, getting a bad feeling. Level B vampires had healing skills that should have taken care of those right away, unless…

She got them when she was still human.

Sayori looked at the new girl curiously, watchful eyes taking in the reactions of Zero-kun as well as Headmaster Cross. The Headmaster was grinning widely, eyes sparkling and even (she inwardly groaned) slightly mischievous. Zero merely looked at the beautiful (seriously, even with the others in the Night Class she was in a whole other league) new girl with a blank expression, not tensing as he usually would in the presence of a vampire.

"Hello." Sayori said softly, smiling at the new student, who smiled back prettily. "Welcome to Cross Academy. My name is Wakaba Sayori."

"Potter Hayden." The girl responded, bowing slightly, and Sayori noticed that her voice had an almost musical quality. "It's nice to meet you." Headmaster Cross smiled at the two girls, glancing at Zero who was still a bit bemused at the girl's strange nature.

"You've already met Professor Yagari." The Headmaster said after a moment. "I am Headmaster Kaien Cross, and this is my son, Zero Kiryu." He said, switching around their names to accommodate the English-born student.

"Your charge, you mean." Zero muttered mutinously, looking at Hayden and nodding once in greeting. She nodded in kind, and Sayori saw an odd look pass through her eyes, though it disappeared soon after. What she didn't know was that Hayden had recognized the Kiryu name, recalling what she knew of the boy's family when Zero mentioned that he was the headmaster's charge.

"So, Cross has told me that you have a different…feeding method than the others." Yagari spoke up before Cross had the chance to start wailing about Zero not calling him father. "Care to explain?"

Hayden nodded in agreement, gracefully removing her backpack and taking out a small box. As she opened it, Sayori and the others leaned closer in curiosity.

The last thing she expected was to see lollipops. They looked exactly like strawberry flavored ones, but obviously they had a rather more…exotic flavor.

"Blood pops." Hayden announced. "This box will never empty, so I'm good."

"Never empty?" Sayori asked, startling those 'in the know'. The three hunters exchanged glances.

"Yes. My family owns the patent, and managed to use their vampiric energy to create this." Hayden explained calmly, eying the others' reactions and acting accordingly. "Basically, it has a twin at the place where these are made, and the boxes share space, and when one is removed from this one, there's another places in its twin and appears here."

Sayori's eyes widened, having been unaware that the magic that vampires used (unaware that it wasn't actually done using vampire abilities) in such a way. There went one of the laws of physics.

"What are they made of?" Yagari demanded.

"Well, sugar, for the most part. Blood-flavored or not, it's a lollipop." Hayden answered. "Each one has a single drop of willingly donated human blood for this exact purpose, and somehow the company managed to…multiply the blood once it's in the candy. I'm not sure how." She wasn't quite telling the truth, and as she stared at Sayori when she said it, the three hunters understood that magic was how.

One of the laws of Transfiguration was that you could increase something edible if you had some of it, but couldn't conjure it out of nowhere.

Zero grimaced at the thought of someone willingly giving blood to a vampire. He suppressed the thought that Yuki had once tried to help him by doing the same thing, before becoming a self-absorbed bitch.

"Would it be possible for the other Night Class students attending the academy to somehow receive these blood pops?" Cross asked Hayden. "I can name a few who would probably be easier to handle if they weren't required to use the blood pills."

"The blood substitute?" Hayden inquired curiously. "Yes, I've heard that those aren't exactly satisfying. I suppose I could contact my grandmother and have her send more cases to give to the students. They would have to pay, though. The only reason mine is free of charge is due to my family's ownership."

"How much would you estimate?"

That question didn't come from Cross or Yagari, as one might think, but from Zero.

Those in the room aware of his hatred for vampires and distaste at the idea of drinking blood blinked at him in surprise.

Receiving reviews in my e-mail are good reminders that this story does, in fact, exist, and that I should write the next chapter. Just saying...
