A/N: So, this is my first attempt at a story. I have no idea how this will play out or how good it will be, but I've had this idea stuck in my head for months. I finally made an account on this site, and so now I can write stories for all my annoying ideas. Please review, tell me what you like and what you don't. If you have any suggestions, that will be greatly appreciated! Also, I need help coming up with pairings. I have some in mind, but I'm not sure how well I can integrate them into the story, so please give me your input. What pairing do you want to see? I suppose now you should just enjoy the story! Thank you for reading!

Prologue

Mysteries. Enigmas. Paradoxes. They scare people. One fears what one does not understand or know. It is a basic aspect of the human brain. If one cannot understand what is happening, they are frightened. That is how it works. That is how it always works.

This situation is no different. The stories are passed in hushes whispers through a small village sheltered by the vast forests surrounding it. Civilians' eyes widen in fear and admiration and Konoha ninjas look upon it with a new sense of pride and hope that they, themselves, can become as great.

The stories are of one person, a legend, some say. This person is said to be an ANBU of Konoha. They wear the mask of a blood red fox, and they fight ruthlessly. It is said that the ANBU, Fox, completes S-rank missions in a record time, and those missions are completed with efficiency. When Fox is ordered to leave no survivors, everyone dies within ten minutes. When ordered to clean up no traces are to be found within five minutes. Fox can run from Konoha to Kumo in a day with no stops and still have the energy to complete a mission with maximum efficiency. Fox is a legend to Konoha's civilians, a story to the citizens of other countries, and an idol to high ranking shinobi.

Fox is such a mystery, no one knows who the ANBU is beyond the mask. No one knows if Fox is a boy or girl, or what color hair he/she has. No one knows how tall Fox is or what eye color he/she has. Fox is simply a mystery behind a veil. There, but not really there. The only ones to really know who Fox is, is a certain late old man, a perverted author, and a woman, who looks younger than her actual age.

These three will soon be among many to have seen the famed ANBU.


Chapter 1: S-Rank

The old Team 7, the infamous team of terrible luck, was waiting for their old Sensei in the Hokage's office. The two members had become chunin, finally. First was Sasuke, then was Sakura, whom had became a chunin in the next exam that was held in Kiri.

Naru disappeared sometime after she came back from her three year training trip. Without a word or hint, she just disappeared. Konoha 9, or the rest of it, and Team 9, had asked Tsunade what had happened, but she refused to say a thing. Eventually Naru's friends gave up on trying to find an answer because the Hokage was not giving away any information, but she seemed unbothered, so they assumed that Naru must be okay. They all had at least tried to accept this, though it was difficult.

It has been two years. They are all 17 now, and the Hokage had requested Team 7, or now Team Kakashi, come for their next mission. Kakashi was late again, for he seemed to find joy in being late, even to mission briefs.

Tsunade sighed for the eighth time. It's been two hours, where is that good-for-nothing, stick-up-his-a-

POOF! Kakashi's entrance cut off Tsunade's thoughts.

"Sorry, Hokage-sama. I got lost on the road of li-"

"Cut the crap, Kakashi," the Hokage cut in. "You can't get lost on a narrow, one-way road. It doesn't happen." Kakashi sweat dropped. "Anyway, I got a mission request from a farmer in Wave. It seems they nee-"

An ANBU appeared, kneeling beside the Hokage's right, effectively cutting off Tsunade, which slightly annoyed her. A tick mark was forming on her forehead before she realized who she was looking at. "Fox."

The ANBU's code name startled the others in the room. Is this the legendary ANBU?

"Sorry, Hokage-sama. Mission success, no survivors. It was restored and Konoha's named cleared."

Tsunade remembered this mission. It was an S-rank, almost SS, but that was only if things went wrong. She ordered Fox to come directly to her office when the mission was completed no matter what. This mission was too important to put on hold.

The rest of the room's occupants looked on the ANBU with confusion. Was this really the one? Were they really looking at the person whom had all of the shinobi nations peeing their pants?

A weight was lifted off of Tsunade's shoulders. "Good jo-"

The sound of a knock at the door interrupted Tsunade for the third time. A tick mark fully formed on the impatient Hokage's forehead this time. "WHAT?" She shouted, making Team Kakashi flinch. The ANBU remained in her crouching position, unmoving.

"Ts-Tsunade-sama, there is someone here to see you," the voice of Shizune sounded from the other side of the door.

Tsunade put her head in her hands, "Tell them to go away. I'm busy."

But Shizune stayed. "Tsunade-sama, you really want to see this person." This piqued Tsunade's interest. She raised an eyebrow. "And they have come a long way," Shizune added, as if trying to convince the Kage.

"Bring him in." Team Kakashi stood, forgotten, to the left side of the room, and the ANBU remained kneeling beside the Hokage's desk.

The door opened, revealing a pale Shizune and a very old man wearing a sparkly dress and a matching pointed hat. His eyes were bright blue. He looked serious and amused at the same time.

Tsunade realized Team Kakashi was still standing there awaiting orders, and so she absentmindedly dismissed them. The ANBU, though, remained kneeling by the Hokage's side. "Fox, rise."

The ANBU did as commanded and rose. Fox stood behind the Hokage, alert and ready to defend her.

The old man realized this and continued in the room slowly as to not startle anyone, not that he could. "Hokage-sama," he said warmly. "My name is quite long, but I shall introduce myself as Albus Dumbledore. I have come to request a very important mission." The Hokage rose an eyebrow as to indicate that she was listening. "You see, I am from outside the shinobi nations-"

Tsunade stood from her chair in a second. "WHAT DO YOU MEAN?" she yelled, "There isn't supposed to be contact between us! Outsiders are to remain outside the barrier and we are to be left alone! That is the way it is; the way it's always been!"

Albus Dumbledore knew this was going to happen, but he was still taken aback by the force of the Hokage's words. "Hokage-sama, I am aware of the barrier, and I am aware that you want nothing to do with outsiders. But, I am willing to pay any amount, for money isn't an issue. This is especially because the mission I am requesting is very important for the fate of the world, and that shall also include the shinobi nations."

"Okay, you better start talking." Tsunade wanted to know what made this old lunatic want to come here. He didn't look too crazy, but you never know.

Albus bowed his head in acceptance. "I believe you are aware of the existence of magic, yes?" Tsunade nodded. "Well, Outside, magic users and non-magic users, or wizards and witches, and muggles, are separated. Muggles are not aware of the magic that surrounds their lives everyday. We have always been able to coexist in this way, but now, this is not possible. You see, a very powerful wizard has risen once again. We thought him dead in the past, but that seems to not be the case now. His name is Voldemort and he is threatening the magical and non-magical communities-"

"Wait what does this have to do with us shinobi?" Tsunade asked, slightly irritated. This guy just busts in her office, demands her help, and then says he's from the Outside. That's it. He is crazy, and now he is drying her patience quickly.

"Well, it's more than just Voldemort that we have to look out for now. It seems that somehow the barrier was punctured and someone from the shinobi nations made it through to our side. His name, Orochimaru."

"WHAT? Damn Orochimaru," the Hokage muttered. "Okay, so you have my full attention. Continue," she demanded.

Albus continued as told, "Orochimaru has teamed with Voldemort, and now I fear the safety of both the Outside and the Inside. We must stop them. I have reason to believe that both are first going to target my school, Hogwarts. The reason is because of one boy, Harry Potter. When he was a child, Voldemort attempted to kill him, but was not able to because the spell deflected, supposedly killing the Dark Lord himself. Now that he has risen again, he is going to try to kill the boy again, this time with help. Since we are not familiar with the ninja arts, I was hoping I could hire some of your ninja, or shinobi, to protect the boy and the school. Once the threat is no longer valid, we can unite to defeat them."

Tsunade, who had been listening intently, nodded. "Yes, it seems that is the case. Well, I have just the person for the mission." Albus raised his eyebrows, looking surprised.

"A single person? Hokage-sama, forgive me, but my school is quite large and the duty is also far too big for one person to carry. I-" Tsunade cut him off with her raised hand.

"Don't worry about that. Anyways, this person is definitely qualified for this mission," Tsunade stated with a smirk. "Fox."

With that said, the ANBU standing behind the Hokage disappeared and reappeared beside the old man, kneeling. This surprised Albus further.

"Hokage-sama."

"Take your mission scroll for details. This will be an S-rank mission. You are to leave tonight. Dumbledore-san, do you have any specific orders."

Albus thought the situation over a bit before stating, "I do believe that if this guard mission will work, then the guard must go undercover as a student."

"Yes, that's true," Tsunade agreed. "Well then Fox, you will go undercover as a student, therefore you will have to be unmasked. Dumbledore-san, I must tell you that her identity is an S-class secret. In other words, if you reveal her identity to anyone, you will be executed."

Albus was taken aback, but replied nonetheless, "Of course, Tsunade-sama. Her identity will die with me."

Tsunade gave the old man a genuine smile, "Good. Fox, remove your mask."

A short "Hai" was said before the ANBU stood and removed her mask. She was about 5'5". Her skin, although not seeing the sun for years, was evenly tanned. Her hair was silky and blonde, and it was pulled back in a french braid that reached the small of her back. The ANBU operative's eyes were a bright blue, but unlike the old man's, they were dead and void of emotion. This startled Albus. Why would such a young face have such emotionless eyes?

Tsunade smirked once more. This will be interesting, very interesting, she thought.

That evening, Albus Dumbledore and, the now dubbed, Naru, made their way to main gate of Konoha. Their destination was the Outside. Dumbledore planned to get out through way of apparition. Since there are several tears in the barrier, they should be able to use the simple method.

Dumbledore held his arm to the girl beside him. She was now wearing civilian clothes, for she would stand out too much wearing her usual ANBU uniform. Instead of ninja shoes, she had black chucks. She was wearing a light blue camisole with black, full-length leggings. On top, the ANBU wore a black zip-up hoodie to hide her tattoo. Her hair was tied up in a loose ponytail, letting strands fall to the side loosely.

Naru didn't understand why Dumbledore wanted her to take his arm. She didn't even know how they were supposed to exit the barrier. All she knew was that she hasn't touched a single person for years without the intent to kill and viceversa. She stared at Dumbledore's arm for a second longer before taking it reluctantly. Instantly, they swirled out of the shinobi nations.
