A/N: Well, since there are some people that want me to continue this and I already had some of it written up, I figured why not? I've also decided to read all seven harry potter books again this summer and am therefore in a very naruto/harry potter crossovery mood lately. I should really be studying for finals right now, but I hate math and while biology itself is interesting, studying for it is not. So, here you people go. The first part of it is the one shot I posted called Sleep Deprivation.

Kisame chanced a brief glance towards his obviously irate partner. They had been traveling for five days with two breaks to get an hour of sleep each and some chocolate for Itachi. Needless to say, both shinobi were very tired, very hungry, and very ready to kill the next thing that crossed their path.

It had all started when Leader had gotten word that the Kyuubi vessel was being sent on a long-term mission to some school called Hogwarts in some place called England. The Kyuubi being Itachi's target, Kisame and his partner had been the ones to have the misfortune of getting sent to this England place to retrieve him.

"Kisame." The shark-like man turned to his younger and shorter partner. Itachi was frowning and staring at an empty wrapper.

"What is it, Itachi-san?" he asked, already knowing. Itachi didn't take his eyes off the wrapper. The Uchiha suddenly stopped and turned to Kisame, holding the wrapper up and looking positively pitiful.

"It's gone." Kisame felt a head ache coming on. Honestly, was he Itachi's partner or his baby sitter? He swore that sometimes he couldn't tell. Over the past few years Kisame had discovered that when Itachi got very little sleep, he craved chocolate. When he ate chocolate, the infamous murderer had a tendency to act very childish, especially when he ran out of chocolate. Five days of getting no more than two hours of sleep definitely counted as very little sleep.

"What do you want me to do about it?" Kisame finally asked, taking the empty wrapper. Itachi shrugged.

"I don't know. I just felt that you needed to know that I was out of chocolate...got anymore?" Kisame actually walked over to a tree and banged his head against it. If only the Uchiha clan could see their prodigy now. If only Itachi's little brother could see his big brother. That would be funny. Sasuke probably had no idea that his brother craved chocolate when he was sleep deprived. He finally turned back to his younger partner.

"I think you've had enough chocolate for now," Kisame said. And then he nearly died from shock. Itachi was pouting. The Uchiha Itachi, infamous S-class missing nin and murderer of his own clan, was pouting like a little child.

"But...but I want some more!" Kisame's jaw dropped. What the hell? The shark-like man quickly regained his composer and scowled at the twenty-one-year-old.

"What are you, five?" he snapped. Itachi glared.

"I want chocolate now!" Kisame twitched. Really, what had Leader been thinking? How did he expect them to make it to this Hogwarts place in five days or less and retain their sanity? Honestly.

"You can't have more chocolate!"

"I WANT MORE CHOCOLATE!"

SMACK

Itachi blinked. He slowly lifted a hand up and touched the spot on his cheek where Kisame had smacked him. He then slowly turned his gaze towards his partner.

"Thanks," he muttered. "I think I needed that." Kisame slowly relaxed from the defensive position he'd jumped into. Itachi, in a slight daze, started walking again in the direction they'd been traveling before. Kisame counted to ten then followed. This was going to be a long year.

Snape didn't like their new History of Magic professor. The man was creepier than himself, which was saying something as he had been told on many occasions that he was quite a creepy character. The blue guy beside the new professor was also pretty creepy. After all, you didn't meet many people who naturally had blue skin and gills on their cheeks. The black cloaks and red clouds were also rather intimidating.

The nervous professor glanced over at Dumbledore, who had been spending the last few minutes simply surveying the two men before them. The headmaster had been ecstatic when he had first learned that he would not have to fruitlessly search for a new professor after Binn's unexpected retirement, however, now that the new professor and his friend were here, he was beginning to rethink his decision.

McGonagall, meanwhile, was trying very hard to keep her fear as well hidden as possible. It had been bad enough meeting those two guards over the summer. These two gave off the same kind of aura, only scarier.

"Dumbledore." Every pair of eyes in the room landed on her. McGonagall gulped. "Um...are you sure these two are...qualified for this…kind…of…job…?" She trailed off weakly when a pair of coal black eyes fixed her with a chilling gaze. Perhaps she should have kept that to herself until the new professor and his friend had left.

"My dear Minerva, I'm absolutely positive that these two are perfectly capable of teaching the students," Dumbledore replied cheerfully.

"They remind me of those two guards you hired," Snape muttered. This seemed to catch the shorter of the two stranger's attention.

"Guards?" he asked amusement flashing through his dark eyes. Dumbledore turned back to his two guests.

"Yes. Due to recent events it has been requested that security be increased here so I hired two shinobi from another land to help out." Itachi felt like cackling evilly (the chocolate was still affecting him), but restrained himself due to the fact that he might lose the job before he'd even started and Leader would most definitely not be pleased it that were to happen.

His right hand twitched slightly. He had the sudden urge to go kill a small harmless animal. Hm…perhaps he should tell Kisame to never let him near chocolate again. It seemed to make him more psychotic than usual.

"May we meet them?" the Uchiha asked, forcing himself to smile rather than smirk maliciously. It was painful. Kisame gave him a small look out of the corner of his eye. Itachi glanced back, an evil glint in his eyes.. Kisame sighed. He had a bad feeling about all of this.

"I don't see why not," Dumbledore said with a shrug. "I believe they might be joining us for dinner tonight in the Great Hall." Itachi nodded.

"If you'll excuse us, we'd like to get settled in. And don't worry, we'll find the way down ourselves later on. No need to send anyone to fetch us." Itachi turned and walked swiftly out the door, Kisame right behind him.

Back in the room McGonagall collapsed against Dumbledore's desk and Snape tried desperately to regain his composure.

This year would sure be...interesting.

He had a bad feeling about something. What he didn't know. All he knew was that over the years he had learned to trust his instincts. They almost never let him down. He brushed his sopping raven bangs out of his face. It had started pouring only a few minutes ago and he was already soaked.

"Hey, Sasuke-teme! Come check this out!" Sasuke leaped out of the tree he'd been standing in and landed beside Naruto. The blond was squatting in front of a huge black...thing, staring at it. Sasuke crouched down beside his friend and frowned in confusion. It looked like...a spider.

"What do you think it is?" Naruto asked, reaching out and poking it with a kunai. Sasuke also pulled out a kunai and started poking it.

"It looks like...a spider." Sasuke stood up and stepped back a ways. He tilted his head to the side and stared hard at the black thing. Hm...Eight legs and lots of eyes. Yep, it was a spider all right. Naruto was suddenly standing beside him.

"I think you're right, teme," the blond commented. There was silence for a while as they both stared in fascination. Then, "That's one big spider." The Uchiha silently agreed. The thing was as big as Sasuke. Suddenly, Naruto's stomach growled. The raven-haired shinobi sighed.

"Let's go, dobe. We can come back tomorrow."

"Yay! Food!" Within seconds Sasuke had already lost sight of Naruto, who had dashed ahead at the thought of going back for dinner. The raven shook his head, a small smile on his lips.

Itachi had to try very hard to keep himself from falling out of his chair and laughing his ass off at the look on Sasuke's face when he walked into the Great Hall and saw him. The look of pure horror mixed with homicidal rage was extremely comical. Naruto didn't seem to notice anything was wrong until he realized that Sasuke was no longer walking beside him. The blond glanced back then followed Sasuke's gaze to where Itachi and Kisame were sitting. Naruto, without thinking, pointed at Itachi and shouted, "YOU!"

Itachi snorted in amusement (after making sure no one was looking of course) as Sasuke whacked Naruto over the head for his stupidity. Kisame was chuckling beside him. All the other teachers at the staff table had gone silent and were staring at the two guards, who were now arguing in their native tongue. Itachi was able to pick out a few choice words he knew his mother would have punished Sasuke severely for using. Finally, the two managed to get to their seats at the staff table and start eating. Lucky for the two younger shinobi (note the sarcasm), the only remaining available seats were next to Itachi and Kisame. Thus the seating order went like this: Naruto, Sasuke, Itachi, and then Kisame.

Dumbledore, noticing the sudden tension, walked down to their seats and observed the situation. The raven-haired guard, Sasuke if he remembered correctly, was alternating between glaring at his partner and glaring at the new professor. Said professor was ignoring his young look-a-like in favor of calmly eating his meal, a small smirk gracing his lips. The other guard, Naruto he recalled, was glancing nervously at the new professor and the new professor's friend. The new professor's friend himself looked to be on the verge of bursting with barely contained laughter. At last, the headmaster spoke.

"Do you guys know each other?" Kisame almost choked on the piece of chicken he'd been eating. Itachi's smirk widened. Sasuke and Naruto exchanged a glance.

"Oh yes, quite well in fact," the elder Uchiha answered. Dumbledore smiled uncertainly.

"Well, that makes introductions much easier." Dumbledore returned to his seat, praying that he'd still have his History of Magic teacher in the morning, though if he'd known anything about the current situation between the four shinobi he'd have been much more concerned for the young guards. The rest of dinner was spent in tense silence until...

"Sasuke?" Sasuke blinked at being addressed so casually by his older brother. Normally when they met he was labeled as foolish little brother then lectured on how his hate was not strong enough and all that.

"What," he snapped, eyeing his elder sibling warily. Itachi stared at him for a long extremely tense moment of extremely thick silence.

"Do you have any chocolate?" Sasuke choked on the glass of pumpkin juice he'd been drinking. His head snapped over to Itachi, who had a desperate look in his eyes. Memories of his childhood concerning just what happened when Itachi got a hold of chocolate, especially when he was as tired as he looked now, flashed through his mind. He glared.

"No!" Itachi sighed in disappointment. He really wanted some more chocolate.

A/N: Well, hope you liked it. Sorry if there were any mistakes. I didn't feel like rereading this thing a million times to make sure things were percfect. If you happened to catch something I'd appreciate it if you'd mention it in your review so that I can fix it.

Also, I have absolutely no idea what is going to happen in this fic, so don't expect speedy updates.

Please R&R!!
