Disclaimer: I don't own Naruto, Harry Potter, or Satoshi, who is from Ouran High School Host Club.

Summary: When Hayden Potter turns seven, she receives a letter from a school that teaches the Lost Shinobi (Ninja) Arts, including a scholarship that gives her information on her family. As Hayden accepts the offer in the hopes of finding somewhere that she can call home, she is brought into the hidden world of the Elemental Nations, the former countries now being allied and forming the academy. Hayden is made aware of her magical heritage on top of her ninja heritage, and Hogwarts will get a few interesting surprises when she reenters the magical world as a full-fledged ninja.

Warnings: Blaise x Hayden, female Harry, female Naruto, SasuNaru, spoilers, Uzumaki Lily and Hayden, some angst, some bashing (Dumbledore and Dursleys for sure, haven't decided on everyone else), possible yaoi or yuri pairings at some point…I think that's it. Sorry if I missed anything.

Enjoy!

Hayden screamed as the dark figure lunged for her, grabbing her by the arms and holding the struggling girl against his chest. He held something over her nose, and at the funny smell, Hayden held her breath.

"This one's worth a pretty penny." The man said to his companion with a sneer. "Uzumaki and Uchiha will probably empty their bank accounts to get her back."

"I don't like this…" the other said uncertainly. "Pissing off the demon bitch and her psychotic husband? What the hell were we thinking?!"

"You were thinking that you want to die today!" a female voice hissed furiously, not pleased at the insults she was hearing or the bastard's grip on her sister.

The two men spun around, and Hayden's eyes watered at seeing her older siblings.

'Get away!' she wanted to scream, but the man's hand was held tightly over her mouth. 'Niisan…neechan, please…don't…'

The nine year old passed out due to lack of oxygen, breathing in the chloroform on the rag still held to her nose.

The black haired twins froze as the man holding their sister dropped her to the ground.

She wasn't moving. They couldn't even tell if she was breathing.

The normally calm Sarada and the normally cheerful and upbeat Satoshi screamed in fury as they launched themselves at their sister's attempted kidnappers…

Five minutes later, when a frantic Naruto and Sasuke found them, it was to see Sarada cradling Hayden in her arms as Satoshi sealed the two men's bodies in a storage seal that he'd had in his weapons pouch.

Both pairs of eyes shone a dark red, one black tomoe (comma-shaped mark) in each eye.

Naruto bit her lip, eyes taking on a hard glint of determination as she stared at her three oldest children.

Hayden had been skittish and slightly paranoid since those two bastards had tried to take her away from them, and the twins…

Well, they had had their first kills that day.

And they hadn't even graduated from the academy yet.

The worst part was that when Naruto and Sasuke pulled them aside individually and had a talk with them, none of them were meeting their expectations.

Hayden wasn't afraid because of what had nearly happened to her, but because she was afraid of being taken away from her family, the first ones who had accepted her for the so-called 'freak' she was.

Sarada and Satoshi were of a similar mind. They felt guilty at having taken the men's live, but they didn't regret it, because Hayden had been in danger. They also felt horrible that she had been 'hurt,' and if they had gotten there even a minute later, they might have lost their sister forever.

Still, life moves on.

After a few weeks of therapy, the three children were back to their normal selves, as much as they could be anyway.

And the bounty for the two would-be kidnappers had been added to the bank account the twins would get access to when they graduated.

"Hayden, are you finished with your homework?" Naruto called from downstairs.

The ten year old groaned, dropping her head on her desk. "Ugh, what do I even need astronomy for, anyway? How is that even magic?"

"It's good to know for potions and Herbology." A voice came from the doorway, and the black haired girl turned to see her mother leaning against the door frame. "Divination. And combat, probably. You'd want to know when the full moon is in case of werewolves."

The blonde woman smirked at her daughter, who smirked back.

"I think I'd be able to tell if there's a full moon without learning about what stars and planets are in what constellations." Hayden said dryly. "And divination is a load of bunk unless you're a Seer."

"Which is why you aren't learning it." Naruto agreed, entering the room, only to sit on Hayden's bed. "So?"

Hayden sighed. "My homework for school is done."

"And the assignments your tutors gave you?" Naruto prodded, feeling odd.

Had it really been that long ago since she was the one trying to get out of doing her work?

Oh wait, she still did. That's what Kage Bunshin were for.

The other Kage had never forgiven her for her liberal abuse of the jutsu to get out of doing paperwork, but she knew that it was just because they couldn't use it to the extent that she could.

They were just jealous of her awesomeness.

"I drew the diagram of Nora for Herbology." Hayden mused.

Naruto smirked, feeling accomplished. At least one of her kids had picked up her habit of naming plants.

"I worked out the chemical equations for potions, and wrote the papers for history and care of magical creatures." Hayden continued. "Finished the diagram about the chain of command in the wizarding world. Runes and warding took about three minutes, but it's the stupid star charts that take forever. They aren't hard, but it's just…tedious."

Naruto nodded in understanding. "Well, why don't you take a break, then? You can work on it tonight. For now…I was thinking we could go to the city for the day."

Hayden's eyes brightened considerably.

When Naruto said city, she was referring to the outside world, not the village.

"What are we waiting for?" she asked excitedly, throwing on a thin gray jacket and grabbing her mom's hand. "Let's go!"

The blonde laughed as her daughter pulled her out the door.

"Mom, PLEASE!" Satoshi pleaded, clasping his hands together and falling to his knees in front of Naruto.

Hayden didn't join him, but it was a close thing.

The blonde sighed, exasperated. "You two have perfectly good brooms at home!"

"But not that broom!" Satoshi did NOT whine, thank you very much.

Even if anyone else would tell you otherwise.

"I can pay." Hayden added shyly, ogling the shiny and sleek broomstick, much faster than anything she'd ever flown before.

Her brother huffed, pouting slightly.

"And one for Satoshi, of course." Hayden added, causing her brother to grin.

Until Sarada came up behind them and smacked them both on the head.

"I'd get you something too." Hayden pouted, glancing at her sister as she rubbed the back of her head.

"No, Hayden." Naruto sighed. "You know you can't use your trust fund. Dumbledore-teme is probably keeping an eye on it."

The Hogwarts headmaster was the only person the family insulted without making the insulter put money in the cursing jar as a penalty, something the kids (more Satoshi and Hayden than Sarada) took advantage of mercilessly.

"Which is why I opened a new account under Uzumaki Hayden and had the goblins transfer funds from the Potter family vault, not my trust vault." Hayden said proudly.

Naruto sighed in exasperation. "The answer's still no. Maybe in a few years."

Hayden and Satoshi pouted slightly, but let the matter drop.

"Okay." Hayden agreed. "Can we get a pet then?"

Naruto hummed thoughtfully, debating whether or not it would be worth it to see her husband's face.

"Sure, why not?" she answered, deciding. "One for each of you."

The kids cheered.

In the end, all of them left with animals, except for Sayuri, of course.

Naruto had bought all of the toads in the shop, including an interesting one that had real gemstones that had apparently grown naturally on its back.

As the holder of the Toad summoning contract, she thought that it was her duty to free them, and was intending to do so the moment they got home.

Sarada ended up with a little gray wolf pup she named Romulus, and was already mumbling how she would bribe her friend Kira-chan, Kiba-sama and Hinata-sama's daughter, into giving her a few tips on how to train him.

On the other hand, Satoshi ended up with an adorable female kneazle—basically a more-intelligent-than-normal cat. He named it Baste, and she had black fur with heterochromatic eyes, one blue and one gray.

Yeah…the twins had helped Hayden research for her history paper on mythology a few months prior, hence the names from Roman and Egyptian mythology.

Hayden's choice of pet, however, was the most unusual.

Especially the fact that despite it not being a nin-animal like the Inuzuka dogs, she could understand it as if it were speaking a human language.

*Flashback*

Hayden bit her lip, eyes widening at all of the amazing creatures in the shop.

Dogs, cats, birds of all kinds, fish, turtles, rats, mice, toads, frogs, bunnies—

But it was when she got to the snake section that things get interesting.

"Are you talking?" she asked, slightly dazed as she stared at all of the serpents.

~A Speaker! ~ One of them hissed in surprise.

"Speaker?" Hayden's eyebrows furrowed in confusion. "Of course I can speak!"

~He means Parselmouth, dear. ~ Another voice, obviously female, assured her.

"…Huh?" Hayden asked.

~You're a Parselmouth, a person who can speak.~ The first snake hissed impatiently. ~Our great language is called Parseltongue, which you are speaking right now.~

Hayden gaped. "How can I speak a language without knowing I can?"

There was no physical response, but she got the feeling that the snake would've shrugged if it could.

*End Flashback*

She ended up leaving the shop with a Runespoor, which was a five feet long, three-headed snake with orange and black stripes wrapped around her shoulder.

Naruto wholeheartedly approved at the color.

The thing about Runespoors was that each head had a separate mind, and was in charge of a certain thing.

The left head was the planner, the middle head the dreamer, and the right head the critic.

From what Hayden had been hearing, the critic never shut up, constantly…well, criticizing everything that it saw.

Honestly, no wonder the shop owner had told her that the other two heads often tried biting the critic's head off, often teaming up to do so.

Still, if two heads were better than one, how much better would four heads be?

"Mom said one pet each." Satoshi muttered thoughtfully. "I wonder if yours counts as cheating."

Hayden and Sarada shrugged.
