My first cross over so please go easy on the reviews and I hope you enjoy!

It's based on the fifth book for those who want to know! ;D

Disclaimer: I do not own Harry potter or D-gray man (but I wish I did)

Voldemort stalked across the room, impatient.

He had an appointment with, what was the name again, Tyki Mikk? And the man was late.

'My apologies for my lateness'

'Finally' Voldemort whirled around to see and middle aged man wearing a suit and top hat. He had a greyish tinge to his skin and his dark hair was simply swept back.

'Now about our deal…'

'Are you insane?'

Those were the first words that entered the deathly silent room.

Rose, the newest addition to the exorcist ranks stared blankly at Komui along with the rest of them. Them being Lenalee, Allen, Kanda and Lavi.

Kanda 'che-ed' and looked away.

Lenalee simply stared.

Allen was trying to hold in his laughter.

Lavi wasn't even bothering.

Rose was thinking of different ways to kill Komui.

The reason? They were being sent back to school, and Komui had turned up in the school uniform.

'Well it was orders from central, apparently the headmaster at this school, Hogwarts, wanted to join forces to defeat an enemy.'

Lavi, choking back laughter, asked 'Why we have dresses for a uniform?'

Komui looked slightly put out.

'It's not a dress, it's a robe!'

Rose raised an eyebrow.

'You do know robe means dress in French, right?'

'Oh'

'Either way I'm not going' stated Kanda, 'send someone else'

Komui shook his head, 'orders are orders Kanda, you'll all be leaving tomorrow.'

'Che'

Komui sighed, then perked up as he remembered something.

'Ah yes, Rose, you'll be teaching at the school. A subject called…wandless magics.'

'WHAT!'

- (fast forward to Hogwarts express, yes I am very lazy)-

Harry towed his trunk towards the end of the train looking for an empty compartment.

Reaching the last compartment he opened it to find people already inside.

There was a boy with bright red hair that rivalled the Weasleys with an eye patch arguing with a girl with two long pigtails.

A long-haired Japanese girl, wait boy, staring out the window that was holding a sword.

A half Asian looking girl with a really long ponytail held up by a pin with a rose ornament and a black choker with several silver symbols on it.

Then there was the old man (he had white hair didn't he?) trying to break up the argument that was happening next to him.

'Umm… excuse me, can I sit in here?'

The girl with the choker looked up.

'Sure, if you don't mind the noise.'

Pulling his trunk in he sat down next to the girl.

'I probably should introduce myself… us,' stated the girl, 'I'm Rose, the anti-social guy over there is Kanda, carrot head there is Lavi, the other girl is Lenalee, the white hair guy is Allen. Lavi shut up before I turn you into a parrot!'

Mollified, the red head, Lavi was it?, closed his mouth and sank into his chair with a pout.

Sighing the old man turned, 'Finally' he muttered.

Curiosity prickled in Harry's mind, was he the new DA teacher?

'No he isn't the new teacher, his 15 despite how he looks.'

Harry stared at Rose.

'How did you know what I was thinking?'

'Does thinking count as muttering out loud?'

'Ah…'

'Technically,' interjected Lavi, 'muttering can be a type of thinking, it is called thinking out lo-eep!'

Lavi yelped as a small throwing knife embedded itself next to his head.

Rose had another knife in hand prepared to throw.

'Lavi, shut up'

This time it was accompanied by a glare from everyone in the compartment. (Except for Harry, I feel sorry for him, he has no idea what's going on)

This time, Lavi actually went quiet. Harry raised an eyebrow before settling beside Rose.

'So where are you guys from? I haven't seen you before.'

'Exchange students. For some random reason we practically got ordered to go to Hogwarts.'

Several heads nodded in agreement. The rest of the ride continued in several heated arguments between Allen and Kanda, Rose and Lenalee separating them by either a solid punch or a kick in the gut respectively. Lavi and Harry playing exploding snap, then Allen kicking Harry's butt in poker (A/N god Allen's scary when his like this!). This continued until a very annoyed looking Hermione came in with Ron in tow.

'Do you know who is the Slytherin prefect?' fumed Hermione.

Harry could guess from Hermione's reaction.

'Malfoy?'

'YES! And that cow Pansy Parkinson!'

'Umm, excuse me, but could you explain what a prefect is?' Lenalee asked.

Hermione and Ron seem to just realize they weren't alone.

'Oh sorry didn't see you, I'm Ron and this is Hermione.'

The others introduced themselves and got to know each other. That was till a certain Slytherin decided to show up.

'What's this? More mudblood friends Potter? You really have no life do you.'

'Why you little…' began Ron until he was interrupted by Rose.

'Sorry, can you repeat that?' she asked her eyes flashing dangerously.

'Oh, are you one of Potter's mudblood friends?'

'Mudblood? Well it depends on which context. I'm sure you are much more of a mudblood than me seeing as you're worth as much as dirt. Isn't that right ferret boy?'

Malfoy hissed angrily. No one ever spoke to him like that. The golden trio snickered. Rose had no idea how close she was to the truth, especially after the impostor moody had turned Malfoy into a ferret.

'You'll pay for that! Furnunculus!'

Rose simply disappeared. Malfoy stood shocked before he heard two thuds behind him.

Whirling around, he saw Rose standing over the two limp bodies of Crabb and Goyle.

'Pathetic bunch of losers aren't they,' she grinned darkly, ' oh well we still have a rodent problem.'

'S-stand back! I'm the Slytherin prefect you know!'

'So? I'm a teacher you know.'

Silence reigned in the area as everyone processed the information.

'No way your kidding, a teenager like you can't be a teacher!'

'really? Well I have proved you wrong haven't I? Well as your teacher I'm telling you to go away unless you want some serious repercussions.'

Gritting his teeth Malfoy made his way back until Rose called, 'don't forget your rubbish! We can't have people littering the corridors can we, especially not by a prefect! 3'

Malfoy then had to endure the humiliation of dragging two massive bodies back to his compartment.

Most people in the compartment when Rose returned were laughing their heads off at Malfoy's humiliation. Hermione was sitting their looking a bit stunned while Kanda was being his usual impassive self staring out the window.

'You're a teacher.' Stated Hermione.

'Yes'

'You're teaching at Hogwarts.'

'Yes'

'You're a teacher.'

'Yes'

'You're a teenager.'

'Yes, I suppose'

'You're a teacher.'

'I think I've already established that.'

Hermione snapped out of her stupor, choosing to ply Rose with multiple questions about the coming year.

'Hey, Rose, I thought you were against being a teacher?'

'Weeellll, after meeting an idiot like him, I think being a teacher will be a whole lot more fun then I originally thought it would be.'

The golden trio shivered at the evil grin that she wore on her face.

Upon arriving at the station, the new professor and the new students disappeared into the crowd.

Suddenly Hermione stopped in the middle getting to the horseless carriages.

'I forgot to ask her what subject she was teaching!'

So how was it? Good? Bad? Please review and tell me so I can write a good story out for you!
