Welcome to chapter one! This takes place after Kakashi Gaiden and in Harry's third year, although I might throw in a few things from later books, no major plot spoilers. Japanese will be used sparsely. I would like to thank NorthernHarrier's Abyssus and SalineRabbits' Pridian Moon for inspiring this fanfic. Enjoy!

Chapter 1: In Which Tables become Puppies

Dear Hiruzen Sarutobi,

I am overjoyed by the news of the war's end. The attack of the demon fox and the death of Minato are a dark stain on the victory. But as your war ends, it seems mine is about to begin once more. As you know, the boy Harry Potter defeated the dark lord Voldemort some years ago. Recently, however, his followers have become active once again. I am certain they are planning something. There are even rumors of shinobi in the area. If that wasn't enough, the mass murderer Sirius Black has escaped from prison and is after Potter. Your forces must still be strained, but I ask if you can spare one of your shinobi to guard Potter this coming school year. If I remember correctly, Kakashi Hatake is still young enough to pose as a student, and was on his way to becoming a skilled shinobi the last time we met. This is an ideal opportunity for him to finally learn to use his magical abilities. Of course, I will cover all costs and transportation, and give S-ranked mission pay for the whole school year.

Sincerely,

Albus Dumbledore

Dear Albus,

My village is beginning to recover from the war and the Kyuubi attack, so I have considered your offer. Very clever, Albus. Looks like Kakashi will receive some wizard schooling after all. Yes, Kakashi has indeed exceeded all of our expectations and become the youngest Jonin and ANBU captain in our village's history. He is more than qualified for this mission. I have a feeling he will be a magnificent wizard, as he is already skilled with his family "White Chakra", or as you call it, magic. But I warn you, Albus. He is not the boy you met all those years ago. Kakashi will complete this mission. But, for Sakumo's sake, please try to help him.

The Sandaime Hokage, Sarutobi Hiruzen

Albus Dumbledore leaned back in his chair and sighed. The Hatake clan was the only known magical family on the shinobi continent, and now there was only one member left. Kakashi's father had never attended Hogwarts, but nevertheless Dumbledore had made a point to visit Kakashi after under-age magic was detected in Kohona, like the previous Hogwarts headmaster before him had visited Sakumo Hatake.

/Flashback/

Dumbledore studied the white haired boy sitting in a too-big chair across from him. The boy, no more than four, stared back, his expression confused.

"Your clothes are weird. Why do you wear that?" A small Hatake Kakashi asked.

"Well," Dumbledore chuckled, "I rather like it." It was one of his particular favorites, a lime green robe with shining golden starbursts. "Sometimes it's nice to wear something fun, don't you think?" The old wizard gestured at the boy's outfit, an austere black item more appropriate for a funeral than anything else. But the boy across from him shook his small head vigorously.

"Nu-uh! An enemy shinobi could see you from a mile away. And Daddy says that too much clothes make you slow." Kakashi wrinkled his nose like he'd smelled something rotten. "And your beard is really long. Someone could grab it and pull you off balance and then kill you. Or they could get your sleeve and twist it and-" he stopped.

"Oh, sorry," the boy said scratching the back of his head, "I'm not 'upposed to talk about shinobi stuff to civilians. Daddy says it scares you."

It was unnerving, almost frightening hearing a four-year old talk so innocently about death. But Dumbledore kept his opinions to himself; he had to remind himself that this was the shinobi culture, and the Hatakes were famous for producing young geniuses.

Dumbledore forced a smile. "Well, it doesn't matter. What's important is what happened yesterday. Would you tell me about it?" To his credit, the wizard didn't even blink at the enlarged, fang-like canine teeth the four-year-old showed when he giggled.

"I was trying to climb trees. Daddy said I should only try when he's there to watch me, but he was tired from a mission so I went by myself. I got so high, almost as good as Daddy did when he showed me. But when I got to the very top I messed up. I thought I was gonna fall, but instead I slid down a big slide." Kakashi grinned again. "It was really weird, because there wasn't a slide there before. But it was really fun too. I wanted to go again but Daddy saw me and then brought me to the Hokage. Then later Daddy said I had to talk to you and then I came here."

"That's quite a story, Kakashi-kun. Now let me ask you this: do you know why that happened?"

The boy thought about it for a moment, then shook his head no.

"You used magic. You're a wizard, Kakashi-kun."

The four year old blinked. "Magic? But that's just pretend."

Dumbledore only smiled again at this. He'd heard it before, of course, from other muggle-born students. They were usually convinced after a demonstration, but sometimes they still chose not to go to Hogwarts. That's why he wanted to talk to Kakashi when he was still young and not yet a real shinobi; there was a better chance of him saying yes if he knew about it long enough. The last Hatake to go to Hogwarts nearly fifty years ago was known as one of the greatest magical prodigies of his time. Dumbledore was determined to get little Kakashi some wizard training, especially now that the Hatake clan had almost died out.

"Am I now?" The old wizard drew his wand, and, with a swish, turned the table between them into a wriggling brown puppy.

Kakashi's eyes widened in disbelief. "Genjutsu?" he asked.

"No, it's for real. Go on, pet him." Hesitantly, the white-haired boy got off the chair and carefully touched the dog's head. The puppy yipped and licked his hand. Then curiously, Kakashi squatted down to the dog's height and murmured to it quietly. A moment later he stood up.

"He's just a normal dog. Not a smart ninken(1) like Mommy or Tsume-obasan's dogs. But still, how did you do that?"

"Magic, Kakashi-kun. It's not just for storybooks, it's real. It's what turned a table into a puppy and what saved you yesterday. You have the gift of magic, and if you choose to, you can learn how to use it at my school."

The boy's eyes lit up.

"Can I do that training? I could turn all my enemies into… into squirrels and they'd all run away!" Kakashi laughed at the idea.

"Not right now. You have to be older- ten years old to go to my school." Dumbledore turned the puppy back into an end table, making the four-year-old's face fall.

"That's not fair! I'm just four, and I still go to the Academy!" The little boy pouted.

"Well, you'll have to wait to go to my school. But I really must be going now. Think about it, and when you're old enough I'll write you and ask if you still want to attend my school."

"Oh. Alright, I guess. Goodbye Dumbledore-sama."

"Goodbye, Kakashi-kun. I hope to see you again. Tell your father thank you for letting me come."

Dumbledore Apparated back into his office fully pleased with how the meeting had gone. He had put the idea of magic into Kakashi's impressionable young mind, but as much as the headmaster wanted to talk more, he kept the meeting short and didn't pressure him too much. The boy was only four, after all, barely out of toddler years. But Dumbledore had a feeling that Kakashi would accept his offer.

Which is why, six years after the meeting, he was surprised at the short answer to his letter.

Dumbledore-san,

I thank you for your offer, but my village is at war and needs every man it has. Being a shinobi is too important. I cannot leave.

Hatake Kakashi

/End Flashback/

Now, finally, he had found an excuse to get Kakashi to Hogwarts for some wizard schooling, even if he was only acting as a bodyguard. Once the young shinobi realized that Harry was relatively safe in the castle, he would receive a free education almost unhindered by the mission, Harry would have extra protection from Black, Sarutobi would receive a ridiculously high mission pay, and Dumbledore would get his genius wizard.

Everyone wins. At least, that was the plan.

Sarutobi said he was worried for Kakashi in his letter. It didn't take a genius to figure out what that meant. After all, he was an ANBU at only thirteen. How much battle had he seen? Had he killed? As much as Dumbledore would like to respect Shinobi cultures, underage soldiers were something he could never approve of.

All he could do was help Kakashi as best he could. How bad could it really be? A little post-traumatic-stress disorder; Dumbledore could handle that. Heavens knows he'd dealt with troubled students before. A few weeks at Hogwarts and civilized society and the boy would settle down.

Dear Sarutobi,

I accept your offer. Attached are travel instructions and the pay in advance. I'm sending my deputy headmistress to pick him up. I've never met any shinobi besides you or Sakumo for security reasons you know, and I won't deny that I'm excited to meet Kakashi. Don't worry about us; we can handle any problems he might have.

Sincerely,

Albus Dumbledore

A/N- And there you go, the first chapter! Yay. Yes it was short; the other ones will be longer. It was really more of a prologue than anything. Writing from Dumbledore's POV wasn't nearly as fun as Kakashi's, which might have something to do with the length. Anyway… review! It's only one chapter, but everyone has to start somewhere. Tell me what you think of the idea, or how I did the flashback (all italics gets a little annoying, I think), or just whatever you want.

Oh, and heck yeah I just gave Kakashi Inuzuka fangs.

(1) Ninken are ninja dogs, like Kakashi's summons and the Inuzuka's dogs.
