A/N: Ok, so I know that there is already, like, two of these, but I wish to make my own. I promise, they won't follow you other guys who also wrote ones. Mine take's place in book 5, where Harry, Ron, and Hermione are 5th years. I hope you like it! I do not own D. Gray-Man! or Harry Potter.

"Do we really have to do this?" Allen asked Komui as they looked up at the castle framed in the moonlight, high on a cliff. Beside him, Lavi, Lenalee, Kanda, Miranda, and Krory stood in the cold night air.

"Yes, the headmaster of this school reported odd appearances. He knows more than other people, aware of the Akuma and the Earl. He's requested the help of the exorcists; you guys." Komui explained, looking at the exorcists before him.

Lavi was smiling, as usual. Miranda was twisting her hands together, apparently nervous. Lenalee stood, staring up at the moon, the bright white reflecting in her eyes. Kanda was staring at the castle with an odd look of disgust, and Krory was looking in the opposite direction, at a train station.

"Hey Komui, are you gonna stay with us here?" Lavi asked. Komui turned his attention from the castle to Lavi, and nodded. "Cool…"

"What's that?" Krory said, pointing at the disserted train station. Everyone turned to look at it.

"Oh, that's how the students come to this school," Komui said, not turning around. "You will be posing as students from another school. It's your mission to investigate this school, kill the Akuma you come across on the way, and keep your cover! We don't want anyone knowing about the innocence except the few people who do already." As he finished, he turned to face them.

"What's this place called?" Kanda finally asked, leaning against a post.

"Hogwarts School of Witchcraft and Wizardry," Komui said, looking down at the piece of paper he was holding. "The students should be here any moment; on the train." He finished.

How did we get in this situation anyway? Allen asked himself.

One day ago.

"We have a new mission for you all… or the generals do," Komui said as the last of the group wandered in. "You must investigate a school, upon request of a Professor Dumbledore. He has noticed Akuma—and yes, he knows about the Akuma, lurking about his school, so you have to go and help out. I'm sending all of you, Lavi, Lenalee, Kanda, Miranda, Krory, and Allen. There seems to be a lot of the Earls machines, so all of you are needed."

"What sort of school is this?" Lenalee said, looking up from the packet.

"A school of magic!" Komui said dramatically. There was a loud 'tsk' from Kanda, and Komui turned to look at him. "Yes Kanda?"

"There's no such thing as magic!" Kanda said instantly, saying the thing that was on everyone's mind.

Komui just stared at him for a couple seconds, then answered, "You'll find out soon enough, all of you." Kanda grumbled something, but went quiet after Komui gave him a 'just-shut-up' look.

"So, you will go to this school. I shall come with you," Komui finished. Everyone was silent as the mission sunk in.

Back in the present.

"So, we have to pretend we're students?" Krory asked, thinking about how old he was, along with Miranda. "I'm sorry Komui, but I don't think me, or as a matter-of-fact, Miranda, will be able to pretend we're students."

"I've thought of that. You'll be my aids, as I am going to be taking over a class," Komui said, looking around.

"Ah, Yer here!" a gruff voice sounded behind them. They all turned, and Lavi muttered a small 'whoa' under his breath. Standing before them was a very, very large man. He was taller than all of them, and twice as wide as well, and had a very bushy beard. "Name's Hagrid, I'm the Gamekeeper at Hogwarts. Dumbledore sent me to meet ya. And I have to take the first years up to the castle."

Komui smiled up at Hagrid. "Yes, we're here!" he said as everyone else regained their ability to talk.

"Oh, here comes the Hogwarts express!" Hagrid exclaimed, and everyone else turned once more as a bright red steam engine pulled into the station. It screeched to a halt, and once stopped, the doors where flung open. Students came piling out. "First years, to me! First years, over here please!" Hagrid shouted above the heads of the excited students.

A group of scared looking 11-year-olds came nervously up to Hagrid. The exorcists were overwhelmed by the number of students, and didn't notice three students who had come over to talk to Hagrid.

"Oi, Hagrid! Hagrid! Hey!" a tall boy with bright orange hair said loudly. The exorcists turned quickly, surprised. Komui was the only one not surprised.

"Hagrid, we've missed you!" a girl with bushy brown hair followed the boy with orange hair. Hagrid turned to look at the orange haired boy, the girl, and another boy with jet-black hair, and smiled.

"Hey Ron, Hermione, hey Harry! How are ya guys?" Hagrid asked them loudly, forgetting about the exorcists behind him for a second. "Oh ya, could ya guys help these—" he motioned to the group of seven people in odd jackets, "—people up to the castle? Dumbledore asked them here from their school as special guests. Can you get them up to the castle?"

Harry turned toward Allen and the other exorcists. "Sure!" he said, smiling. "Come on then, we don't wanna miss our ride up to the school." And he led them away, Hagrid waving merrily.

"What exactly are we doing here?" Allen whispered to Lenalee.

"Just what Komui said, investigate," she replied. Allen sighed, padding after Harry and the other two.

"Whoa…" Lavi said, stopping in his tracks. In front of them where horse-less carriages, where the horses should've been, there was just space. "How does that work?"

The girl turned, laughing slightly. "Its ok… there always like that… Harry, what's wrong?" She turned with a worried expression to the black haired boy. He was standing very still, staring at the carriages.

When the girl said his name, he jumped, then looked around, grinning. "It's nothing… saw a shadow or something."

The girl looked at him for a couple seconds, then shrugged. "Ok, well, only a couple people can fit into one carriage. So, I guess you're gonna have to separate." The exorcists looked at each other, then shrugged.

- - - - - -

"Hey Harry, look at their jackets," whispered Ron, pointing at the peoples jackets while Hermione talked about the horse-less carriages. Harry looked at their coats, and noticed a strange silver cross on their chest.

"Wonder what it means…" Harry replied. But then he noticed that the person with long black hair in a ponytail was staring at them. His gaze bore into them, and Harry turned away. "Kinda creepy…"

- - - - - -

"Ok, that's ok… how are we gonna split up?" Allen asked the exorcists. They looked at each other again.

"Doesn't really matter," commented Lavi, looking around.

"I'm not going with Beansprout," Kanda muttered. Everyone looked at him, then back at Allen, who had assumed a black look.

"Beansprout?" echoed the red-haired boy. Kanda turned back to look at him, glaring at him, which shut the 15-year-old up. The glare from the 18-year-old was very venomous.

"Ok, well whatever… just stay together… don't split up to much," Komui said, moving over to an empty carriage. Miranda, Krory, and Kanda followed him. Allen looked at Lenalee and Lavi.

"Guess we'll go together," Lavi said.

"Hey, you guys can ride in own carriage!" Harry said, motioning to an empty carriage. Allen shrugged, and walked over to the carriage. He climbed in, followed by Lenalee and Lavi. Harry came in last, sitting next to Ron and Hermione. The three exorcists sat together on the other side.

"So, what's you're name?" the brown haired girl asked Allen.

"My name's Allen," he replied.

"Mine's Lenalee," Lenalee said, looked at the three people in front of them.

"My name's Harry Potter," Harry replied, and stared at them, and seemed to wait for some sort of reaction. Allen, Lenalee and Lavi just stared at him blankly. "Ok, guess you don't know me…" he said.

"What's your name," asked the red-haired boy, pointing at Lavi. Lavi smiled at him.

"Name's Lavi! Nice to meet you. What's yours?" Lavi asked.

"Ron," the red-haired boy answered.

"And I'm Hermione," said the brown haired girl. "So, why are you here?"

"Oh, um… apparently your headmaster asked us here as his guests," Allen answered. Harry glanced at Ron.

"What's with your, um, uniforms? They're really fancy… ours is just plain. You must all have lots of money," Ron said, staring at the silver buttons on Allen's jacket. Allen shook his head.

"No, our, um, school gives them to us," Allen said, fiddling with one of the silver buttons. Ron just gapped at him. Hermione glared at him.

"Well, welcome to Hogwarts!" she said, smiling. Lavi, Lenalee and Allen smiled back. The carriage jerked to a halt, and Harry opened the door. The exorcists and Harry, Ron and Hermione exited the carriage, Harry glancing back at them with an uneasy expression. They walked over to where Komui was standing in front of the large wooden doors.

"You ready for this?" he asked them. They all nodded, and with Harry, Ron, Hermione, entered the large doors.
