A/N: This is technically a -Man/Harry Potter (Year 4)/Doctor Who crossover, but Doctor Who isn't as important as the other two, merely a plot device, so... Yeah. I'm technically on vacation, but I've got a whole bunch of plot bunnies hopping around my head, so expect to see new stories.

Disclaimer: I'm to tired to type this, so I'll let the characters read it.

Neah: A new story! And I'm in it!

Allen: Neah. Disclaimer.

Neah: Oh yeah, right. Everybody together now. One, two three! *Conducting.*

Everybody: Kenzie Perth does not own -Man, Doctor Who, or Harry Potter!

Neah: No, I do.

Allen: Be quiet.

Allen was at breakfast when he got word of the newest mission. Normally, he would have been fine with the timing, but seeing as he had just returned from an all-night battle with some high-level Akuma, he was particularly hungry. He had, as a matter of fact, refused to leave the table until he was finished with his meal, despite the sharp blade of Mugen pressed to his throat.

Finishing rather quickly, perhaps more quickly than usual, Allen was still in a dark cloud when he Lavi, Kanda, and of course, Leenalee navigated their way through piles of paperwork to the partially buried desk of one (fast asleep) Komui Lee.

Lavi poked the Director. Twice. Komui continued to snore loudly. Lavi grinned in anticipation at what he was about to do, bending over to whisper in the man's ear. "Leenalee's eloping with Kanda."

The words' effect was instantanious. The white-clad, blue-black-haired man clung to his sister for dear life, sobbing and wailing loudly. Leenalee's face was bright red, but she managed a scathing look at Lavi that clearly promised pain at a later date. Lavi hid behind an annoyed (but slightly amused) Kanda, screaming "Protect me, Yuu-chan!" Chaos ensued.

-A Few Minutes Later-

Komui now sat at his desk, the complete picture of maturity and calmness. The four exorcists sat opposite him, wondering what he was making them wait for. Every time one of them opened their mouth to question or complain, Komui woule shush them and tell them that all would be revealed soon enough.

After the thenth time, about, that he had gotten this reply, Lavi, who remained particularly insistent, even after the others had given up, muttered darkly to the world in general. "It'd better not be anouther Komulin." Brightening, the red-haired bookman turned to the irate samurai next to him. "Don't you agree Yuu-cha- Eep!" He barely managed to avouid being decapitated by Kanda's sword.

Leenalee watched the ensuing argument with a hint of concertn, but mostly amusement. She turned to the Director, who had become slightly miffed about the Komulin comment, and who had taken to muttering things like, "What's wrong with my dear lovely Komulin?" and other things of that nature.

"Brother, what are we waiting… For?" Her voice trailed off as the argument next to her ceased, leaving Lavi still hanging by his hair from Kanda's grip and Mugen pointed (for the second time that morning) at Allen's throat.

A crash was heard outside, followed by the sound of very faimiliar squabbling and fighting. Accompanying it was a hummed melody that all of them wished to have never heard again. The bickering was cut off by an even more familiar voice. "Jasdevi. Stop frightening the pathetic humans and get over here. In case you haven't forgotten, we're here for a reason." The voice was getting closer, and at the last word, the door knob rattled as someone placed their hand on it. The exorcists tensed, Innocence activated and at the ready.

The doar creaked open. A pin could be heard drop. And in spilled the Noahs. Komui smiled widely from his seat behind the desk. "Please welcome your new teammates!"

There was a confused silence as the sentence was processed by the other occupants of the room.

"Wait, what?" Allen managed to choke out. Lavi almost dropped his hammer on his foot. Kanda's glare merely intensified, while Leenalee facepalmed.

On the other side of the room, the Noahs were having similar reactions with Komui's proclamation. Tykki glared at Komui, to shocked ot speak, while Sherryl swept Road into his arms despiter attempts to get free and tackle Allen. Wisely, similar to Leenalee, facepalmed.

Komui smiled pleasently. "You'll all be working together on this particular mission."

Tykki choked. "And – how… Exactly is this going to work?" He gestured at the exorcists. "If you don't remember, a couple weeks ago we were trying to kill each other! We came to speak to you, not to get stuck with them!"

Another few minutes of arguments ensued, but somehow, both groups (mostly due to Leenalee) found themselves all sitting across from Komui at his desk.

He grinned. The exorcists winced. A grinning Komui either meant a new Komulin or, (at this thought, Lavi gulped) something worse. Clapping his hands together, he cleared his throat. "I have a mission, as you've probably guessed. A couple hours ago, I had a request from an old friend who I owed a favor to. A school under one of his friend's protection has come under attack." He frowned, his glasses glinting.

"Akuma?" It was not one of the exorcists who had asked this, but rather Road, who was clutching Lero. The Noah of Dreams was swinging the pink pumpkin-tipped umbrealla around in circles, ignoring its protests.

Komui nodded gravely.

Before anyone could say anything, Tykki spoke. "We've been having problems with the Akuma as of late. They've been breaking free, losing control – we certainly haven't ordered any to attack any school, if that's why you've invited us down here."

Kanda shifted in his seat, raising an eyebrow. "Che."

Komui smiled. "I know you haven't." His grin got wider. "You see, this school that's under attack, it's in the future."

There was an unbelieving silence after that. Finally, Lavi asked the question that everyone in the room was silently asking. "What is this school called?"

Komui looked at him dead on. "It's called Hogwarts."
