A/N: Well, another story... This is my first Crossover though, and my first time writing anything that has to do with Harry Potter, so I don't know how good it is. I tried, though, so that counts. I don't know a lot about Naruto though, so don't kill me if I get something wrong! Anyway, warnings are below, I recommend you read them, and just so you know, I used Google Translate for the title and chapter title, so I don't know if their correct or not. Anyway, enjoy my first attempt!

Warnings: Mild cussing, yaoi (don't like, don't read), possible blood-shed (most likely to have, but will be pretty mild, I hope), possible OOC-ness... Um...

Summary: A Chunin, A Jounin, an S ranked mission, a crazy old man (at least in their opinion), bratty teenagers, and a castle. What could possibly go wrong with this situation?

Pairings: Eventually KakaIru/KakashiXIruka, Others undecided

Chapter One

Mada Hajimatta Bakari

Scratching filled the room, along with the occasional annoyed grunt. A group of 22 children were all glaring down at the paper in front of them. Unanswered questions glared back at them from the paper. A few of them chewed their lips nervously as a voice rang out through the room.

"Ten minutes left!" A sigh escaped the speakers lips as he scanned the room tiredly. He watched as some of the students shifted and squirmed. If there was one thing he hated most about his job, it was patching the students, particularly the ones he liked, suffer from the tests he had to give out. His gaze went to the clock on the other side of the room. "Five minutes!"

He stood slowly, putting his hand on his desk as he did so. 'Well, at least its the last test for a while. That'll put them in a good mood." He thought as he slowly gazed around the classroom. His brown eyes flickered from student to student. "Times up!" He said and received groaning and slight whines in reply. A small grin made it's way onto his face.

"Now, before I release you, remember that this is just a short break and that you'll have a test on everything once you come back!" He said before nodding towards the door. "Now, get out of here!" His grin grew wider as many of the students ran out of the classroom, excitement plastered on their faces.

A sigh passed his lips when the last student left. He began his trip through out the classroom, picking up the tests the students has done. He glanced down at one and saw it completely filled out, even though almost every answer was wrong. "Hmp," he chuckled lightly.

Picking up the last paper and setting them down on his desk, his mind drifted. "Now, what to do first. Should I grade the test, or work on updating their grades in my book...?" He was unaware of his surroundings as he sat down at the desk, starting to correct and grade the test.

A sigh passed covered lips as a figured stood with his hands in his pockets, gazing up towards the sky. Quite frankly, he was bored out of his mind, what with all three of his students now with their own Sannin teachers and such. Another sigh passed his lips as he sat done on the grass, running a hand through his sliver hair.

"Hmmm... Sometimes I really do miss being an ANBU... but other times I'm glad I quit..." His mind wandered slightly. "What I really miss are the missions... Always difficult and made my mind think a little... If only a little..." He played with the grass around him, his mind wandering randomly as he did so.

Her fingers tapped on her desk as she scowled down at the letter. It looked like it was written on parchment and in green ink. The fancy print of the letter was giving her a headache, but it also didn't help that she couldn't find her sake. An impatient hoot came from the large tawny owl beside her, his beak clicking softly. She glared at the owl, but to no effect. She turned her gaze back down to the nuisance of a letter, re-reading it for the sixth time.

"Dear Godaime Hokage,

You may be wondering the purpose of my letter and why it has been delivered to you by an owl. Well, I'll answer one of those questions now. You see, we've had a bit of a problem at my school for a while now, and it has really only become horrible. You see, a certain Dark Wizard by the name of Voldemort, or Tom Riddle, has recently been "resurrected", so to speak, and he is currently targeting a certain fifth year student of mine.

This student is known as Harry Potter, or the Boy Who Lived. Voldemort has been after him for a while, but in the recently held Tri-Wizard Tournament, they came face to face and they both came out alive. Now with Voldemort around, I'm fearing that he will round up his Death Eaters, other Dark Wizards, once again.

Now, the purpose of this letter is to ask you if you would happen to be able to lend us one of your Shinobi, preferably and ANBU or Jounin. I'm willing to pay a hefty price for his or her services if you agree, which I hope you do. Oh, and also, I was wondering if you could send one more Shinobi in order to teach at my school, Hogwarts, for the year at least. I'll double the pay if you do, and he or she will be simply teaching a Self Defense course. If you agree then I will go into details with him or her later.

Now, if you agree to send one or two Shinobi, please have them touch the paper weight I have provided. It is a Portkey and will take them to where they need to be at 4:30 tonight. Well, I hope you agree, and be sure to feed the bird once you get this message. He's flown a long way.

Sincerely,

Albus Dumbledore"

Her frown deepened before she sighed, hearing the owl clip his beak impatiently once more. "Fine, fine. I'm accepting," she grumbled as she wrote, "Accepted" on the back of the letter. The owl took it quickly before taking flight, soaring through the open window and into the horizon.

"Urgh... Now, who should I send on both missions...?" She mumbled, her eyes narrowing.

He yawned, stretching. The sun was going to set soon and he had finally finished updating his student's grades. He quickly shut his book before standing up and scratching his the scar across his nose, wishing he could just sink into his bed at this exact moment. But, fate seemed to be against his wishes when the door to his classroom was slammed open by an ANBU operative who seemed to have a... fly mask?

"Eh, doesn't' matter," he thought as he glared at the ANBU. "How can I help you?" He asked with forced politeness, not really wanting to deal with people at the moment.

"Hokage-sama requests you in her office, now," he said quickly before turning away and leaving.

He threw his hands up into the air with a sigh. "Just once can I leave this classroom without being called somewhere else!?" He said to himself. "Ah well. At least it isn't the mission desk," he shook his head before leaving the classroom and doing the hand sign ram, and disappearing with a poof of smoke.

He ran his hair through his silver hair once more, fidgeting under Tsunade's gaze. In all, he was slightly confused but he didn't show it, thanks to his mask. One moment he was sitting under a tree reading Icha Icha and the next he was here, thanks to a certain ANBU of which he didn't know.

"Maa... Why am I here? I was perfectly fine reading. I don't even know what's going on..." He thought grumpily, but didn't voice his thoughts since he really didn't feel like getting punched. He glanced outside towards the sun. "Sheesh, it's only four! It seems like forever since I was called here."

A poof of smoke beside him broke him from his thoughts. "Ah, Iruka-sensei, your here at last," Tsunade said as the smoke cleared revealing the Chunin. "Now, I have a mission that I'm offering to you both to go on," she continued. "Before I explain anything at all, do you accept?"

He nodded slowly and watched as Iruka nodded slowly, almost hesitantly, as well. "Good. Well, here's the gist of it. Iruka, Kakashi, you two will be attending a wizarding school in England known as Hogwarts," she said, ignoring their looks of confusion. "Iruka, you are to teach a class there known as Self Defense, which should be a breeze for you. Kakashi, you are to guard the school against an evil wizard known as Voldemort and his followers for the year. You must not let anything threatening on the school grounds, understand?"

They both nodded again. "But, Hokage-sama, wizards?" Iruka said, confusion written all across his face. He received a nod as an answer.

"Yes, Iruka, wizards. Before you say anything, yes magic exists, even though you may not believe it. Soon you will though. Anyway, yes you are going to be teaching wizards, pre-teens and teenagers to be exact, and yes they do use "wands". Their magic is similar to our chakra, but they need those sticks in order to amplify it and thus use it. Now, no more questions! I need you both to wear one of these," she said, throwing two silver chains at them

Kakashi looked down at it, his eye narrowing before he slipped it on. "These are translators that will allow you to speak English. The wizards will assume you are speaking Japanese if you speak normally, so just go with it. Iruka, your cover story is that you teach at a wizarding school in Japan and have decided to teach overseas, but since all of the staff positions in Hogwarts are filled, Dumbledore, the headmaster, let you teach Self Defense. Kakashi, you don't have one."

This caused him to roll his eyes as the brown haired man nodded. "Now, I need you each to place a single finger on this paper weight. Oh, and Kakashi?" Her questioning voice made him look at her as he set a finger upon the paper weight that was red and seemed to be shaped like a bird on fire. His eye widened when Tsunade threw him an oval shaped object. Catching it with one hand, he turned it over and saw familiar red paint, porcelain, and eye holes. A grin spread over his already masked face and his eye curled upwards.

"You are not required to take that mask off, and if any of them ask you to, don't. That's an order!" She said as he placed the mask over his face. "Iruka, you will address Kakashi as Wolf during you stay in England, understand?" She received a nod from the Chunin. "Good, well have fun!"

"Hmp. No clothes and barely any information. Now we're being chucked into another part of the world? Well, this'll be one hell of a ride, that's for sure."

A/N: Well? What did you think? Please review and tell me! They make me happy. Anyway, next Chapter coming soon and it'll be longer than this one! Ja ne!
