A/N: Hello everyone! Sooo…. I disappeared off the face of the Earth for a while. I sincerely apologize to everyone who followed, favorited, and reviewed this story before. Life can be… very difficult sometimes. But I am back! And I swear to God, I will not disappear again (though with school and life, updates will be erratic). I have improved the chapters I posted before, and am in the process of writing the others. So I hope anyone who read and liked this story before will forgive me, and give me a second chance. But anyway, this fic is AU, but I'm kind of putting it as sometime after the Order meets the Level 4, and in Harry's fourth year at Hogwarts. It is Yullen, but there will not be any major sexual content in it (because I have never written it before and do not want to start out with it). But it will mainly have "sweet" moments between Allen and Kanda (and it's Allen and Kanda, so it probably won't be too sweet, but you know… a moment's a moment). Also, a hint of LavixLenalee.

Anyway, I think that's everything…. Except the disclaimer. I don't own D. Gray-man or Harry Potter, and I never will.

Dumbledore watched the scene before him silently, stunned by what he was seeing. Three young men, ranging from approximately 14 or 15 years-old to possibly 20 years-old, were fighting a hideous creature that appeared to be a mixture between a baby and an angel. The creature seemed to be very strong and fast, as it was able to take on all three men at once.

One of the tallest boys, who had long black hair held back by a hair tie, fought with a sword. He was extremely agile, and his movements were precise and graceful. He was clearly a very experienced fighter, which upset Dumbledore. A boy of his age (who appeared to be the oldest of the group) should not be so well-versed in battle. Does this mean he has fought creatures like this before? Dumbledore wondered. The thought was very unsettling.

Another boy, who seemed about the same age as the first boy, had red hair that immediately reminded Dumbledore of the Weasleys. He wore an eye patch on his right eye and a bandana in his hair. He was fighting with a giant hammer. Though his fighting abilities also demonstrated his experience with battles, he did not fight as gracefully as the man with the ponytail.

The last boy, who appeared to be the youngest, had white hair similar to Dumbledore. He also had a large scar on the left side of his face, which went through his left eye and ended in a pentagram on his forehead. He was using a very large sword, which, if Dumbledore saw it correctly, was actually his left arm that transformed into the sword. Like the others, this boy knew how to fight, and seemed almost as graceful as the first boy with his sword.

They worked very well together, but it was clear they were having some trouble against the beast judging by the cuts and bruises they were all sporting. Just as Dumbledore was about to join the battle, the creature spoke. "I think I've had enough fun for tonight," it said, smiling evilly. It then struck, quick as lighting, and knocked all three boys into separate buildings. They fell in heaps to the ground, though both the pony-haired boy and the white-haired boy were already recovering. The creature sped toward them, his intent to finish them off obvious.

Dumbledore stepped out from his hiding spot, pulling out his wand. The three boys and the creature turned to stare at him, shocked by his sudden appearance.

"What the fuck do you think you're doing?! You can't attack it with a stick, you old fucker! Get out of here!" The pony-tailed boy shouted angrily.

"Run, quickly! It won't hesitate to kill you!" The youngest boy yelled desperately at Dumbledore.

Dumbledore did not reply, instead raising his wand and saying "Stupify!" The creature froze, unable to move from the spell Dumbledore had cast upon it. The boys eyes widened, surprised that the old man had affected the creature, then sprung into action. All three attacked the beast simultaneously, causing it to explode.

After everything had settled down, Dumbledore introduced himself to the three Exorcists.

"Hello. My name is Albus Percival Wulfric Brian Dumbledore, Headmaster of Hogwarts Schoolf of Witchcraft and Wizardry. If I may ask, who are you three? And would you by any chance happen to know what that creature was?"

The three boys stared at the man silently for a few moments, then glances warily at each other. "It is nice to meet you Mr. Dumbledore," said the scarred boy, smiling politely. "My name is Allen Walker. The redhead's name is Lavi, and the girly-looking man with the ponytail is Kanda."

Lavi grinned at Dumbledore, and winked (at least, that's what he seemed to be trying to do. It was difficult to tell with the eye patch Lavi was wearing). Lavi's mischievous grin reminded Dumbledore of a certain pair of red-headed twins, and something made him think that this boy would get along with the twins quite splendidly. The Japanese man to Allen's left, Kanda, glared at the white-haired teen, and looked as if he was ready to kill the boy.

Kanda and Allen then began to argue, while Lavi attempted to calm them down. While they were yelling and threatening each other, Dumbledore got a chance to survey the teens more closely.

Allen, with his white hair, looked much older than he actually was from afar. Though white hair on a young person was odd, it was not unheard of (A/N: Steve Martin, for example, got white hair at a relatively young age.) His scar seemed much worse up close, and Dumbledore wondered how the boy obtained it. His left arm, which he had used to fight the creature from earlier, had returned to its normal form, although it was blackish-red in color.

Dumbledore could now see that Lavi was taller than both Kanda and Allen. Although he seemed as if he was trying to stop the fight between the other boys, he looked as if he was actually enjoying the exchange between the two. Yes, the Weasly twins would certainly like this lad, Dumbledore though, chuckling quietly.

The last boy, Kanda, seemed like the most threatening of the three. He too was taller than Allen, and looked to be very strong. Although all three of them were handsome, he was the best looking (A/N: Okay, he probably wouldn't think that, but I would…. Along with many other people, I think ;) ). He glared and sneered at Allen while they were bickering, but, similar to Lavi, Allen and Kanda seemed to enjoy the verbal (and almost physical) battle they were having.

Eventually everyone was silent again, and Allen began to explain about the Akuma and the Black Order. Allen then asked what Dumbledore had been doing with the "stick," and what he meant about being the Headmaster at Hogwarts. Dumbledore proceeded to explain about magic and the wizarding world. He also said that some creatures, that he now knew to be Akuma, had recently begun to attack wizards, but none of them had any information about Akuma until now.

"Do you think I could meet with Supervisor Komui? I believe it would be in both the Order and the wizards' best interest if we co-operated to defeat the Earl."

"Of course," Allen replied. "We are actually quite close to the Order, and we can take you there if you would like."

"Yes, thank you." Dumbledore replied with a smile. Kanda just "Che'd" and began walking. Lavi yelled, "Wait, Yu!" Suddenly, Kanda whirled around and yelled "Don't call me that, stupid rabbit!" Lavi hid behind Allen and waited for Kanda to continue walking before springing from his hiding spot. Acting as if nothing had just happened between the two, Lavi skipped along to catch up to Kanda. Allen just sighed and shook his head. "Idiots," he mumbled, but followed the other two.

Eventually the four arrived at a tall, looming tower. As they entered the building, Dumbledore was intrigued by what he saw. There were many men and women walking through the halls wearing long brown coats, unlike the boys he was following, who wore black uniforms lined with silver and of varying design.

"Allen, Lavi, Kanda! Welcome back!"

Dumbledore turned to see who had greeted his guides. A young Chinese woman with a pixie cut hairstyle was walking towards the three boys with a happy smile on her face.

"Oh, hi Lenalee!" Lavi yelled ecstatically before bounding forward to give the girl a hug. He blushed, seeming to realize what he had done, and quickly released her, mumbling something about not wanting to get killed by Mr. Sister Complex.

She giggled and said, "Hello Lavi. It's great to see you guys! I haven't seen you since I left for my mission a few weeks ago. Oh, who's this?" She asked, finally noticing Dumbledore, who had been standing silently behind Lavi, Kanda and Allen.

"This is Albus Dumbledore. He needs to speak with Komui," Allen explained.

"It's very nice to meet you," Lenalee said politely. "How about we take you to his office? These three need to report to him about their mission anyway."

Dumbledore agreed, and the four Exorcists took Dumbledore to Komui's office. Lavi burst through the supervisor's door and yelled, "Honey, I'm hoooooomeeee!"

A/N: Well, that's it for this chapter! I hope someone out there enjoyed it (for the second time). And if not, oh well. I really enjoyed writing this, and am glad that I finally got to re-post it. And to those who read this, please review. I would love some feedback (but please try to be nice about it! I need constructive criticism, but that doesn't mean you have to yell at me….)

Thank you so much to everyone who reads this!
