A/N Hello everyone, so I decided to make a crossover of –man and Harry Potter. This is set in the fifth book and after the Level Four attack.

Disclaimer: I do not own D. Gray Man or Harry Potter. Now on with the story!

Allen was sitting at one of the many tables in the cafeteria of the new headquarters, stacks of plates filled with different assortments of food piled high in front of him. Lavi sat adjacent to him eating a small (in comparison to Allen's lunch) portion of yakiniku, and Kanda sat isolated on his own table with a bowl of soba. Lenalee had decided to take some coffee to the science department to check on how they were doing before she ate.

Within minutes Allen had managed to devour all the food and was just polishing off the last of his mitarashi dango. "Wow, Allen, I will never understand how you can eat that much and finish it so quickly." Lavi commented, grinning.

"Huh, what do you mean Lavi, I eat at a perfectly normal rate, and it's everyone else that just eats slowly." Allen said calmly.

Lavi sweat dropped, "Only you would say something like that."

Just then Lenalee sat down next to them with her own lunch. "Hi, Allen. Lavi."

"Hello, Lenalee." Allen smiled, "How's everyone in the science department doing?"

"Oh they're fine, but nii-san wants to see us once we're done eating. He says there's a very important mission."

"Really, so soon after we settled in?" Allen questioned.

"Like I said it's really important mission. Nii-san was very serious," at this Lavi and Allen raised an eyebrow, "like I told Kanda."

"Does that mean Yuu-chan is coming too?" Lavi asked smiling widely.

Lenalee nodded and Allen's expression darkened, "I have to go a mission with BaKanda."

"Haha, don't worry Moyashi-chan, me and Lenalee will be there too!" Lavi said. "Though for us all to be called there it must be really important, don't you agree Moyashi-chan?"

"My name is ALLEN, baka Lavi!" Allen shouted, Lavi just laughed moving away from him.

"Calm down Moyashi-chan!"

"It's ALLEN, A-L-L-E-N, is that so hard to remember." Allen growled, chasing after Lavi. Next to them Lenalee just sighed and continued eating her lunch, why couldn't she have a peaceful lunch for once? She wandered.

Eventually the three friends arrived at Komui's office- after Lenalee had to restrain Allen from doing anything permanent to Lavi that is. Lenalee knocked on the door before entering not bothering to wait for an answer; she knew that her nii-san wouldn't care anyway, Lavi and Allen following. Kanda was already there, leaning against the wall his arms folded and eyes closed. As soon as Komui saw Lenalee he jumped over his desk and hugged her glaring at Lavi and Allen.

"Nii-san, can you please let go of me now?" Lenalee asked frowning at her brother.

"B-But Lenalee, those two octopi were trying to take away your innocence, I won't let them do that to my precious little sister." Komui cried.

"No nii-san, they weren't; now let go of me." Lenalee said, blushing beet red.

"No!" Komui shouted. When he said that, Lenalee's eyebrow started twitching from anger and she kicked him in the head, causing Komui to let go of her and lie on the floor dazed from the pain.

"Now, nii-san the mission?" Lenalee inquired.

"Huh? Oh yes, the mission!" Komui exclaimed, climbing back onto his feet.

"Get on with it!" Kanda growled from where he was standing.

"Of course, I need you all to go to a magic school."

Nii-san = Brother

Just to clear this up, mitarashi dango is Allen's favourite food. Yakiniku is Lavi's and soba is Kanda's.

See you next time. Blue~
