A/N: So, those of you who know me for writing Yugioh, I'm not dead. ^^ I've just been busy with life. I've also moved out of the Yugioh fandom, and into another one...D. Gray Man! So, here is my first DGM fic, a crossover.

I can't guarantee all updates will be this fast, since I had already written this chapter when I posted the prologue, however I'm going to try to update at least once a week. This chapter explains pretty much all AU stuff for DGM, apart from one: Cross is still alive. Why? Because I like him.

*********CROSSOVER

General Allen Walker was hungry. And tired, but food always came before sleep. He had just returned from a mission to get some innocence from the Himalayas; honestly, it seemed like someone was trying to kill him with all these stupid missions to the middle of nowhere. Okay, they probably were, knowing Central.

On the plus side, he could now create an Ark door in a place he hadn't been before, so long as he knew exactly where he was going. The down side was that doing so used up quite a lot of energy, and then there had been a trek up the Himalayas to a remote tribe who hadn't spoken a word of English, and then he had to collect the innocence and get back home, since there wasn't really much room on the mountain passes to open a gate.

So now, really, the only thing he wanted to do was eat. Then sleep in the nice, comfy bed in his room for a few hours. So he made his way to the cafeteria, nodding to the few Finders he saw on the way there who all nodded back in respect. Since becoming a General, he had noticed he had much more respect and power than he was used to, but luckily his friends all treated him the same. And Kanda. Though he wasn't sure if Kanda counted him as a friend. Oh, and Cross, who still called him "stupid apprentice".

Tossing aside these thoughts, he made his way to Jerry, smiling at the man who beamed back at the sight of his favourite exorcist.

"What would you like today, Allen-chan?"

"Well, I would like," Allen proceeded to list as many foods as he could think of that he really wanted to eat right now. And that was a lot. "Oh, and twenty mitarashi dango too, please." He smiled bigger then, giving Jerry his famous charming smile.

"Coming right up!"

Jerry had to have known Allen was coming back with the speed he got Allen's order, the entire thing filling up practically an entire table.

"Got enough there, Moyashi?" A joking voice called to Allen. The young general looked up, pouting.

"My name's Allen." He reminded a grinning Lavi, in between politely stuffing his face with food, careful not to get any on his black and gold uniform. Lavi laughed.

"Sure, sure, Moyashi-chan. Just like Yu-chan keeps insisting his name is Kanda. It's almost like he doesn't know he hasn't a first name."

"Well, he's probably too stupid to figure it out anyway." Allen smirked, feeling happy he'd managed to get in a jab at his rival, even if said rival wasn't here to hear it. In the training rooms, Kanda sneezed.

Sometime later, after eating several times his own body weight in food, Allen walked to his room, glad he didn't get lost once on the way, which was an achievement for him, even if he had been living in the Order for quite a while. Why didn't they pin maps everywhere, then he wouldn't get lost! Okay, so he might still get a little lost with his own horrific sense of direction, but still.

He sat down on his bed, turning to view the large, rather morbid picture on his wall, reaching out a hand to lightly brush its canvas. Mana. The madman who had raised him, who he loved even if he was no longer sure if Mana had loved him or the Noah inside of him.

"He did love you." The voice of his uncle told him from inside his head. Allen sighed, but smiled a little too, grateful to Neah for reassuring him. A knock on the door broke his thoughts and he turned his head to see Lenalee enter his room, her hair now reaching her shoulder blades.

"Hey Allen, Komui says he has a new mission for you."

"What? But I've only just come back!" Lenalee giggled at his expression.

"I know, but this time it's a really big one, pretty much all of us are going."

"Everyone?" Allen stood up. What mission could possibly be so big it required all the exorcists?

"Yeah. Come on. I don't know much about it either."

Allen sighed and walked out, Lenalee following him and shutting the door. She watched Allen out of the corner of her eye as they made their way towards Komui's office. He really had changed since he came here. His "mask" had slipped slightly, and she could tell he felt more open towards them, if only a little. His posture had changed too, he was more confident; something she knew was a product of his training to become a General. He had spent a total of six months training separately under each of the current Generals before being given that title(though she suspected the training with Cross had left him more scarred than before), and it had changed him. He was no longer a child, or even a teenager. At the age of sixteen, he already held more responsibility and knowledge than many adults.

Then again, Lenalee wondered if any of them were ever truly children once they joined the Order. Her childhood, practically her entire life had been with the Order, as had Kanda's. They knew death and pain in a way many people would never know. She smiled a small bitter smile. They weren't children; they weren't people. They were Exorcists. They lived to fight.

After the Alma incident, Allen had gone into a coma. They suspected the Noah inside him was trying to take over, so they attempted to hide him from Central's eyes. In fact, one week into the coma his forehead had started bleeding and the stigmata had appeared, his skin greying. Then the debate began. Some people recommended killing the young exorcist to prevent another Noah from appearing, others said to wait; that they believed Allen was still fighting. A week later, Allen awoke.

She remembered how his eyes had opened, their regular silver colour rather than the gold she had been dreading, and how the stigmata had vanished, his skin turning its natural colour again. She had hugged him so hard Allen could barely breathe, Lavi joining in. After they got over the fact he had woken up, he told them he and Neah, his uncle and Noah, that they had made an agreement. Neah wanted to kill the Earl, and Allen wanted to stay with the Order. They had agreed that they would attempt to peacefully exist, and work for the Order if they still could.

What had followed was a long period of suspicion, arguments and tests, until eventually it had been decided that Allen could stay, provided he and Neah made an oath of loyalty and if either of them looked like they were deserting, all exorcists were given an order to kill on sight. Really, Lenalee thought, it was a miracle Allen had stayed through all of that. But then again, the Order was a family to both of them, and Allen always was the type to do anything for anyone. He was far too good to have such a horrible fate.

As this thought crossed her mind, they reached Komui's office and entered. Komui was, for once; awake, though this might have been because everyone else who was gathered there had woken him up from his napping. Since there was no seating left, the two teenagers stood in a spot that didn't have papers strewn across it.

"Good, now you're all here, I can begin." Komui stood from his desk and began pacing in a slightly agitated manner, quite different from his usually cheerful manner. This was serious. "I have received a message that suggests a place as being the target of a number of akuma attacks, even some possible mentions of innocence. However, what's unusual is the nature of this place. I'm sure you've noticed the decrease in akuma attacks here, along with the Noah somehow disappearing, even though sightings had become quite common. This, in connection with the message I have received, have lead me to a disturbing conclusion. You see, this message...is from the future."

At this, many expressions, which had been only vaguely interested in what the Supervisor was saying, changed into looks ranging from shocked to intrigued, to disbelief.

"How far in the future?" Lavi questioned. Ten year, one hundred years, one thousand years?

"Around a hundred years. The conclusion I have come to is that the Noah have somehow gone into a different time, one without Exorcists. Without Exorcists and the Black Order, they will have no opposition."

"So all of this will have been useless because they will destroy humanity in our future." Komui sighed.

"Yes, Lavi. It seems that way. However, the only way that the Noah could have got there is using the Ark." The mad scientist turned and grinned at Allen. "Luckily, we have our own."

Allen coughed.

"Um, not to disappoint you, but I have no idea how to make the Ark move through time. It might not even be possible since they do have a newer version of the Ark...I've never tried to move through time before."

"Even if you can't do it completely, Miranda's Innocence can control time. We might find a way to combine the two." Yeah, because combining Innocence with something created by the Noah was perfectly safe. Right. "Besides, we have until August the seventh, 1995 to work it out." Allen sighed.

"Okay, I'll try to find a way. But what exactly are we going to do if I do manage it?"

"Well, that was the second part of the message. It seems that in the future, and possibly right now, there are wizards who perform magic with wands." Komui waved his hands to get those gathered to be quiet, since this statement had made some people laugh and other gasp. "In the future, they are involved in a war, not as big as ours, mind you, but still. It could be that our enemy has joined with theirs. In fact, given their enemy has an interest in eternal life, it is likely. Therefore, the man who has contacted me has suggested an alliance between our Order and their resistance, known as the Order of the Phoenix. You will act, in a way, as bodyguards to a school."

"Bodyguards? You want exorcists to act as bodyguards?"

"Not particularly. It seems this man really knows nothing of the Order, or even akuma, however, if Allen can get the Ark to travel through time then it is, theoretically possible for you to travel through time, spend as long as you want in the future, and come back before you even left! Plus, that also means you will be able to protect their entire country, since this war is thankfully isolated to the United Kingdom only, from the same place. Their headquarters is apparently too small to really keep everyone in all the time, so the school might make a good base. Any questions?"

They were silent, all digesting the information in their heads. This could be...interesting.

*********CROSSOVER

Allen stood inside the Ark, thinking, a little frustrated at how this was going. It was currently ten past seven, and he was tasked with somehow using the Ark to get to a different Lab at five o'clock. He played the song over in his head, picturing the lab in his mind, along with a clock that read five. Then he let the image go. It wasn't working. He quickly made a portal to the piano room, sitting down and lightly running his hands over the keys on the white piano.

"Have you ever done it, Neah? Travelled through time?"

"I can't say that I have. It should be theoretically possible, though, since the Ark is technically another dimension." Allen sighed.

"I'll try again." He began to play the familiar song, and found himself singing along softly. He thought about the Lab, about the time he wanted to get there for, picturing the clock on the wall with its minute hand and second hand pointing towards the twelve and the hour hand pointing towards five. He poured his desire into the song. Then he felt it, a gate being made, its doorway leading straight to the room he was currently in. He finished the song before standing and heading out the gate, smiling when he saw the clock on the wall, not exactly as he had imagined it as the minute hand was on the two, but it was close enough. He could now travel through time.

********CROSSOVER

The Exorcists and Komui had gathered in the Ark, waiting for Allen to open a gate to Grimmauld Place, London, August the seventh, 1995 at nine o'clock precisely. They each had a small amount of luggage (Allen had strict orders to pack clothes rather than food), and waited with baited breath, not entirely sure what they were doing. Komui himself had limited knowledge, having told them everything he knew. He was going to negotiate the alliance, and to look after his darling Lenalee.

Allen closed his eyes, clearing his mind of everything except the time and place he wanted to go. A door appeared on the side of a nearby building.

"It's done."

"Good." Komui smiled, and placed one hand on the door knob. "Let's go."
