I don't own D. Gray man or Vampire Knight

The exorcists were heading back to the dorms when they saw Zero and Yuki walking towards the Moon dorms, followed by a mob of screaming fan girls. Intrigued, they followed them to the gate, where the girls lined on either side, behind each prefect. They noticed that when a girl tried to get past Zero, he glared and they went back in place. While with Yuki, at first she manually tried to keep them back, but soon lost patience and a dark aura appeared around her, scaring them to stay in line.

They watched as the gates opened, and the night class walked out. Aidou was 'shooting' the fan girls, and when he came to Yuki, kissed her on the cheek, and went on to class while the girls shot her murderous glares. Yuki rolled her eyes at them before laughing as Kaname whacked him on the head.

Hard.

With a very heavy and thick book.

When the night class was inside their classrooms and the mob gone to their dorms, the prefects approached the exorcists casually.

"You should be in the dorms." Zero said fiercely, earning him a whack on the arm by Yuki.

"Don't be rude!" she scolded him before looking back at the exorcists. "He is right though, even a drop of blood will make the night class come after you."

Lavi gulped audibly, as he dragged Krory and Leenalee off back to the dorms. Allen and Kanda stared at the prefects for several moments, before Yuki started to walk away. Everything happened so fast from there.

Allen grabbed Yuki's wrist, Zero pointed his gun at Allen's head, and Kanda pressed the flat side of his sword against Zero's neck. They stood at a stand still for several moments until Yuki said,

"Put it away Zero, and Kanda, if you so much as nick him with that blade, I will drain every last drop of your blood from your body."

Zero cautiously put his gun away with a sigh, Kanda reluctantly sheathing his sword once again, turning towards Allen and Yuki. Yuki turned to face Allen with a serious gaze and asked,

"Anything I can help you with?" his grip loosened a bit, before she added, "Is this what Mana taught you while you were traveling?"

Allen threw her to the ground yelling, "DON'T BAD MOUTH MANA!" Yuki simply stood and shot Zero a glance that said, 'dont interfere I got this.' She then faced Allen who shouted,

"Or has becoming a filthy wretch like your 'beloved brother' made you so distasteful?"

"You've done it now." Zero sighed as Allen watched Yuki's eyes burn bright red, and fangs appear.

"Don't you dare say that about my brother lowly human, I will drain you of your life force stupid Allen-kun." she said as she drew Artemis, that turned into a scythe. She raised it about to swing as Allen raised his claw into the air, when Yuki felt a hand on her shoulder, and Artemis being lifted from her grasp. She looked up and gasped,

"Kaname!" said person glared at Allen before looking down at his sister who had retrieved her weapon and was now returning it to her thigh.

"Kaname.." Allen growled as he reluctantly deactivated his innocence.

"Now now, is that anyway to greet an old acquaintance?" Kaname asked as he wrapped an arm protectively around Yuki's waist, pulling her into him.

It was after Mana had died, Allen was not yet cursed, but was staying at Kaien's house, who had taken him in. Allen and Yuki were playing by the fire when Kaien entered the room with a boy about their age, he was covered in blood and had such hatred in his eyes.

"Yuki, this is Zero Kiryuu. Be nice Yuki, his parents were killed by a bad vampire." Kaien introduced as Yuki lead Zero to the bathroom to get him cleaned up. Kaien went to Allen's side and they sat in silence until Yuki came back with the boy. He had silver hair and soft purple eyes that were tainted with intense anger and hatred.

"Zero, this is Allen, and this is my father." she said as she sat Zero at a table in the room before running into the kitchen for a few minutes. When she returned, she was carrying some hot chocolate and some soup.

"Here, you must be cold and hungry." she said as she set the food in front of him. She tended to his wounds the best she could before returning to Allen, and they continued to play, while Kaien talked to a tall man who had dark curly hair and was carrying some sort of hunting gun.

A few months later

All three children were sitting at the dinner table, waiting for 'father' to return from the kitchen when they heard a knock on the door. The 2 boys watched in shock as Yuki squealed with excitement and ran to the front door.

"Is that Kaname Yuki?" they heard Kaien's voice sound from the kitchen.

Yuki just giggled in reply, and they saw her dragging a man into the dining room. Allen didn't think much of it, that is, until Zero growled and grabbed a knife from the table.

"Vampire!" he yelled as he went to go stab Kaname. Kaname deflected the attack and his Yuki behind him. Alarmed, Allen grabbed Yuki's arm and pulled her back towards the table.

"Allen-kun!" she yelped in surprise. By now Kaien had darted back into the room, and just sighed in annoyance.

"Don't hurt Kaname-sama!" Yuki yelled at Zero, breaking free from Allen, and running back to Kaname.

"Zero, Allen, this is Kaname Kuran. And, yes, he is a vampire." Kaien said as he pushed llen and Zero back to their seats.

"I am afraid I have upset them, I will take my leave now." Kaname said as he turned towards the door, "Behave Yuki."

Yuki watched him go before sitting back at the table, and started to eat. Zero and Allen looked from each other to Yuki several times until Yuki snapped.

"What do you want?" she asked irritatedly, glaring at the boys.

"Why are you so fond of a vampire?" Allen asked, making Kaein sigh.

"5 years ago, a bad vampire tried to kill me, but Kaname-sama saved me!" she replied with a smile.

"Whatever, just go away." Allen said irritatedly as he turned away and dragged Kanda baack to the dorms with him.
