"Eat." The Headmaster urged Zero who glumly picked at his extra raw steak and side of steamed vegetables.

"I'm not hungry."

Yuki sat in the middle watching the exchange. "Hey Zero after dinner do you want to go patrol! I know how you love keeping those vampires in line! And maybe if you're lucky you can run into Aidou and start a fight!" She stated, trying to brighten the room.

Zero attempted to smile at her before turning back to his plate and cutting a piece of the raw meat and shoving it in his mouth. He managed to swallow before the flavour touched his taste buds. He repeated the process a few more times until he finished the meat, it felt heavy in his stomach but he didn't feel queasy so it was a good sign.

The hunter reached for the steamed vegetables. "It's okay Zero, you don't have to strain yourself." The headmasters voice reminded.

Zero stabbed the vegetation and brought it to his lips, "I want to eat these."

Dinner finished without a hassle and the headmaster was proud of his kid. "If you're up to it, you could do your rounds. Although surprisingly, the vampires have been behaving well. I can only assume it's Kaname's doing."

Zero felt his eyebrow twitch, the headmaster's voice sounded almost teasing. "I'm done." He stated before pushing the empty plate away from him and grabbing his school blazer. "I'll be back after I finish my rounds." He called out as he rushed out of the door, leaving a perplexed Yuki and Kaien Cross.

Aidou ignored the third bead of sweat that rolled down his forehead. 'I just need to wait now.' He thought as he looked at the multiple bloody mixtures under the microscopes. His lab coat and lab in general was smeared with blood, as if a massacre had happened. Tiredly, he wiped his face with a dirty sleeve and sat down on a nearby chair, all he had to was wait for his hypothesis to be either correct or incorrect.

He pulled out an egg timer and set it for fifteen minutes before finally letting his eyes rest after a stressful day.

Zero rested head on a tree trunk and gazed at the beautiful lake, the water glistened under the little moonlight poking out from behind a few clouds. The water looked so blue and tempting, almost as if it was calling out to him. Making a terrible split second decision, Zero easily pulled off his shirt and jeans and jumped into the water.

He felt a wave of shock roll through him but snapped out and started paddling through the water, letting the cold water run through his bruised body. He sighed in relief as the tension slowly left his body, swimming calmed him just as much as horseback riding. He knew when he got out he was going to be terribly sick but I was worth it for a moment of peace and normality.

He turned on his back and looked at the moon that had came out just a bit more behind the clouds, about half of it was showing. Zero looked up a little and noticed he had floated to the middle of the vast lake.

He was having a great time, until he smelt it, the faint smell of blood attacking his nostrils and traveling into his stomach which let out a loud growl. He felt his neglected vampire senses overcome him and with great speed he managed to swim back to shore, ignoring the cold and following his hunger, he ignored his clothes and ran after the thirst quenching scent.

Aidou ran through the school grounds frantically looking for the level D. He was hoping to find him on his perfect rounds so was desperately checking the usual spots he found the silver haired boy in.

"Hanabusa." The familiar voice stopped him.

"Akatsuki?"

"You reek of so much blood, Kaname sent us to find out what was making the Night Class go out of control. You have to wash up before you start attracting Level E's, they've been watching the school closely for a while." Akatsuki warned.

"I will, just give me a few seconds. I have to find Ze-" Aidou's eyes widened but he ran off before his cousin could question him any further, he cursed himself when he felt the others presence behind him. He had almost given away Zero's not so secret.

Aidou narrows his eyes, he couldn't think about that know. He had to tell Zero he had found the answer.

Zero raced through the trees, crashing into a few and getting slapped by various branches, his wailing stomach leading him on. He broke through the trees and found himself face-to-wall with the back door to the Night Class dorms, which was wide open. The scent of blood was stronger but somehow there was still another variant giving off a scent of blood farther off. He ignored that one for now, his stomach only able to concentrate on the stronger scent ahead of him.

Cautiously, ignoring his churning stomach and wild instincts, he entered the door, which revealed a basement. It was almost completely dark except for a dim light lighting a small corner of the room that held a long table with various papers, test tubes, blood samples, and microscopes all over it. He walked over to the first microscope and looked under it. There were many little critters moving under the microscope, he didn't really understand what was happening but the darker red of the cells were definitely overpowering the brighter cells. He moved on to the next microscope which seemed to be made up of the darker cells. And under the last microscope, the darker cells seemed to be battling, and struggling against the brighter cells.

"Fascinating isn't it?" A rich voice broke through the silence making him jump.

"Kaname..." Zero let out a breath of relief before his expression became guarded. "What do you want?"

"I came to see why there was an immense amount of blood spilt on school grounds. It has already started attracting Level E's. Finding you here was a pleasant surprise, now I can assume this is Aidou's workspace." Kaname walked over to the microscopes and looked under each other them, and then read the small notes beside each which seemed to be in a language Zero did not understand.

"I see. So he did figure it out."

"What? What does it say?!" Zero asked.

"He found out how you can drink blood." Kaname walked over to the younger until he had almost pinned him to the wall and made him sit in the only chair in the room. "When I bit you..." He choked back a growl, "when Akatsuki bit you, did you ever bite back?"

Zero gave the pureblood a strange look. "The idea of even drinking your blood repulsed me. I had tried Akatsuki's blood once, I had managed to keep it in until he left but afterwards I was even sicker than I usually was."

Kaname leaned in closer. "So how would you know if my blood was anything like Akatsuki's?"

"Do you have any proof that they aren't?" He asked snidely.

Kaname actually let out a smirk. "Under this microscope, it shows the your cells, the darker red cells and noble cells like Aidou and Akatsuki's. As you can see your cancer cells are slowly but sure overpowering theirs. In this second one, your cells have completely overtaken human cells. And this last one has my blood cells and yours. As you can see this one has the least amount of your cells,though that's not how it started out. Each slide under the microscope had an equal amount of cells. In this last slide, your cells did not and cannot overpower mine, because slowly they will transform into healthy blood cells."

Zero raised an eyebrow. "Am I supposed to be impressed."

Kaname felt a strong need to pinch the bridge of his nose. "Because I can see you do not understand what I am trying to tell you, let me show you."

Before Zero could stop the pureblood, he pulled out a small paring knife and slid the crook of his neck. Zero felt all sense of sanity leave him as his hunger and vampire instincts took over and plunged his fangs deep into Kaname's neck.

Kaname let out a moan as leaned against the wall to support both himself on the man straddling him. He knew this was probably the worst moment, but he couldn't help but feel hot and bothered as an almost naked Zero lapped and sucked at his neck. The prefect had lunged at him when the bloodlust took over, putting them in a compromising position, not that Kaname minded.

Aidou froze mid run, he was halfway to the headmasters house, when he turned and began sprinting back to the Moon Dorms. Akatsuki followed, also having smelt the blood of their pureblooded friend.

It was almost a race to the dormitory, with Aidou hoping it was Zero feeding, yet fearing he would take it too far and Akatsuki's curiosity.

Both made it to the dorms at the same time, but Aidou won to the basement, having known where to go. They were certainly not expecting what they saw.

Kaname sat against the wall, being pinned down by a dripping wet Zero who was only wearing his black briefs and was sucking on the purebloods neck. The pureblood, lost in the heat of pleasure moaned lowly yet audibly and tightened his grip on the others hips.

Aidou felt a wave of heat attack his face and he turned away, meanwhile Akatsuki felt his entire body heat up, but not from embarrassment. Everybody else had stopped what they were doing as the room temperature had risen drastically. Zero's eyes widened, bloodlust red receding to lilac purple. Kaname's eyes however shot open to reveal the dreaded dark possessive red.

Kaname pushed Zero off of him, with much more force than intended and stood up to face the aristocrat.

Aidou could only rush to Zero's side and watch as the two vampires stood ready to attack.

"What is your relationship with Zero?" Akatsuki asked.

"I'm pretty sure its obvious by now." Kaname stated playfully. Although his dark red eyes portraying murderous intent.

Zero opened his mouth to say something but was cut off by Aidou. "You saw under the microscope correct?" Zero nodded. "Then you know that right now your body is currently in turmoil within itself and if you were to get injured your body would be too conflicted to repair itself. Stay. Down." Aidou ordered. "We have to get out of here or else they are going to tear us apart in their rage. They are going to attack each other in a few minutes, and when they do I can guarantee a lot of thing will be destroyed. We have to move now that they are immersed in each other!" Aidou rushed, he dragged the weak legged boy after him, safely making it out of the basement and into the woods.

"I don't know why Akatsuki reacted the way he did..." Aidou panted out, finally able to catch his breath after all the running.

Zero looked towards the moon, which had finally come out of hiding. "I was his lover for quite a while."

Aidou gaped at him but before he could say anything the entire back wall of the Moon Dorms exploded.
