(A/N) Hogwarts will be coming in later. This is to give some backstory if you will. I'm sure you'll manage until then.

Hiruzen sighed at the massive piles of paperwork piled on his desk. He did not want to do the paperwork. Of their own accord, his mind flitted back to when he was a genin and a mysterious girl had shown up to apparently say hi for a few days. Oddly, Hashirama-sama and Tobirama-sensei had both recognized her and greeted her warmly. Tobirama-sensei had almost excitedly introduced her to his students, who were around her age. Emmarine Sandiego really was a fascinating girl. After a few days, she'd waved goodbye, walked around a corner, then disappeared. Hiruzen had looked around for her for a few days, but saw no trace of her anywhere, not even in the records.

When asked, Tobirama-sensei merely said she was a childhood friend, which made no sense, as she looked about their age. Not nearly old enough to have known Tobirama-sensei and Hashirama-sama in their youth. He hadn't seen her since but had heard rumors that a young mahogany haired girl with startling green eyes had slaughtered an entire force of Kumo nin, apparently, it was also the force that had killed Tobirama-sensei.

There hadn't been any trace of her since, and since Kumo still said they were searching for the culprit, he assumed she had died, and gotten rid of her own body. Emma had been a very sweet girl but had a ruthless streak that surprised Hiruzen the first time they sparred. She backed him into a corner, then sat on him, a kunai at his throat. She'd gotten off him after he'd forfeited, and helped him up, all smiles once more. He almost wished she could have appeared to teach his own students that lesson. There will always be someone stronger than you. Always. Doesn't matter if they're alive or not. Sensei's Impure World Reincarnation showed everyone that.

She had been short, little more than five feet tall, having to look up at most people, but she had a presence. One that could hardly be ignored. She was dangerous, and she knew it. She didn't have to release killing intent to be absolutely terrifying. And yet, at the same time, she was kind and hated seeing people injured if she could do something about it. She preferred to end things quickly, with little collateral damage, and little to no extra harm to herself, or others. Unless you had incurred her wrath, she would usually let you off with a simple promise not to attack again. She was perceptive at the same time, almost seeming to be able to read their thoughts and sense their feelings. In battle, her face hardened, all emotions wiped away, yet when it was over, she was all smiles, big toothy ones that lit up her whole face. Hiruzen admitted, he'd had a little bit of a crush for the few days he'd known her. She was incredibly charismatic, and now that he thought about it, an awful lot like Kushina. They had the same bright smile, cheery disposition, and unwavering loyalty to those they care about. Emma had less of a temper though.

Hiruzen sighed. He wanted a distraction from the paperwork. He almost wished Emma could just magically pop in to say hello.

His almost half-formed wish was answered, but not in a way he had imagined. Emma suddenly appeared in the middle of the room, barely standing on her own. Hiruzen recognized her and held up a hand to stop the ANBU from doing anything. She looked terrible, dark bags under her eyes, and she was holding her right side, in addition to a long gash down her left arm, a wound that was dripping blood quickly in her side, and more on her legs. There was even a slight cut on her neck, apparently, they had been aiming to kill.

She looked at him tiredly. "I'm sorry to burst in like this, but I have nowhere else to-" With that, she passed out, eyes rolling back in her head, and beginning to fall.

Immediately, Hiruzen was out of his seat and catching her as she fell, not wanting her to be injured any further. He looked right to where he knew an ANBU was stationed. "Get a doctor. NOW!"

An ANBU with a fish mask nodded to him, disappearing in a shunshin. Hiruzen quickly began trying to staunch the bleeding, not even bothering to think about the floor, which was getting stained with her blood. The other ANBU quickly appeared next to him, one of them apparently knew medical ninjutsu and began to close some of the smaller cuts, including the one on her neck.

A doctor skidded in, replacing the ANBU that was attempting to close the smaller cuts. The doctor's hands lit up green, and she immediately began working on the large wound in Emma's side. It began to slowly close, the bleeding beginning to stop.

Hiruzen knew better than to ask the doctor if she'd be okay, that would just distract the woman, and that could be fatal to Emma.

"Hokage-sama, what do we do with her when she awakens?" One of the ANBU asked.

Hiruzen sighed, looking down at the girl. She looked almost the same as the last time they had met. "We wait for her to recover. She will tell us why in time. I trust her."

"Hai, Hokage-sama." All three ANBU returned to their hiding spots, watching the room carefully.

Hiruzen sighed again. Idly, he wondered why she was still so young. She looked like she hadn't aged a day, except for the blood and the sleepless nights the bags under her eyes told of. Now that he looked closer, the medium purple sheen that had covered her skin was now a black sheen, and he wondered what had changed.

The doctor finished working on the stomach, and moved to Emma's arm, closing up the gash there much more quickly. "I need to see her back," the doctor said quietly. Hiruzen shifted Emma until the doctor could see her back. There were no cuts there, so the doctor ran a diagnostic hand over her. "She'll be okay. She simply needs to recover from the blood loss, and avoid any strenuous activity so she doesn't injure her bruised ribs further."

Hiruzen nodded, thankful to the doctor for probably saving Emma's life. "I will ensure she keeps to those restrictions."

"I would like to see her again in a few days, if possible. I am going to assume you will be keeping her here?"

Hiruzen nodded solemnly. "Yes."

The doctor nodded, then left.

Emma awoke soon after, she had always been a fast healer. She met Hiruzen's gaze, and he was shocked by what he saw there. Gone was the vitality and life, replaced by a dull sadness, and brokenness, that had no place in her vivid green eyes. It reminded him, strangely, of Kakashi's eyes, the 15-year-old boy had seen far too much, the death of his closest friends, then on top of that, the death of his sensei and his sensei's wife, both of whom he'd had a very close relationship with.

"Is that you Hiruzen?" She asked weakly.

"Yes, Emma, I'm Hiruzen," he said softly, noting the very slight happy twinkle enter her eyes.

"Getting a bit old, aren't you? Shouldn't you already be retired, old man?"

"I see you haven't lost your sense of humor," Hiruzen replied, smiling softly. "It's good to see you again, Emma."

She nodded slightly. "Yeah. Sorry, it's been so long, I've been so very busy. It's been almost a year and a half for me."

"It's been decades for us. And, I tried retiring. It didn't work."

Emma giggled a little. "You poor thing. Paperwork as bad as Tobi-kun and Hashi-chan always complained? Oh, and of course Dara-chan did his fair share of complaining."

"Of course," Hiruzen replied. "Emma, are you here to take me up on Hashirama-sama's offer to become a shinobi?"

Emma looked away, her gaze dulling again, and tears gathering at the edges of her eyes. "Yes, I am. I hope it still holds true?"

"Of course it does," he said, smiling.

Emma looked at him, tears still in the corners of her eyes. "I don't have to go to school, do I?"

"Maybe a little bit of tutoring, but after that, you're good to join us as a fully-fledged Jonin. I assume your abilities haven't diminished?"

Emma smiled. "Of course not. How could they, when I was hunting down every single blasted Senhir in the universe. And some in a few other universes." She closed her eyes. "They won't hurt anyone ever again."

"We'll have to see about giving you experience on missions. Most of your tutoring and learning will be happening on missions. We aren't big on classroom learning."

"After all, you can't exactly teach a kid to fight without actually letting them fight," Emma replied. "So, where will I be staying? And, I'm assuming a medic-nin took a look at me?"

Hiruzen nodded, allowing her to sit up. "We may have to get you some new clothes. Those are pretty bloodstained."

Emma looked down at her clothes. "Yeah, you're right. I am covered in blood. And I could use some sleep. Maybe I won't have any nightmares this time."

"Is there something I can do to help?" Hiruzen asked, worried about his friend.

"Probably not. Unless you can find me another twin brother," Emma said, tears gathering in the corners of her eyes again. She looked away, furiously blinking away tears.

"I'm sorry," Hiruzen said quietly. He pulled out a Jounin vest and Konoha headband, handing them to her. "Here you go. Recover for a bit over there, and I'll try completing some of the paperwork before I head out."
