A/N: Alright, first off…if any of you have read my other (uncompleted stories) I'm very sorry, but they probably aren't going to be completed any time soon. I was in an awful car accident and spent a lot of time away from the computer, and when I attempted to update one of my stories, hardly any one read it, and no one reviewed. I'm not complaining or anything, I'd be pretty angry too if I was a reader. In any case, I figured people probably just aren't interested in that story anymore (or my others), so I thought I'd try a new one that has been stuck in my head for a while. I have several chapters hand written so far, and just waiting to be typed, so updates should be fairly regular. I'm very angry at myself for leaving those three stories, but I just can't finish them right now. In any case, I refuse to leave stories like that again. This story will be finished…eventually

So, this is my first attempt at a crossover story…wish me luck. This is going to be a Naruto/Charmed crossover that is probably stretching it a lot for both shows. That's why it is called fanfiction. It takes place pre-Uchiha massacre, and post all Charmed episodes when Wyatt, Chris, and their younger sister (of my own creating) are teenagers. I'll try to explain things to the best of my abilities for those of you who may not be familiar with either show, and you can always ask questions in reviews etc. On with the story, which will eventually be an Itachi x OC.

P.S. – I will try very hard to get correct the Japanese honorifics, but if I'm told I'm fucking it up too bad, then I'll probably stop. Also, for those in the Charmed fandom who are unfamiliar with Japanese, the names are backwards with the last name being said first. Example: Instead of Chris Halliwell it would be Halliwell Chris, but I will only use this on Naruto characters.

Prologue: An Introduction and Something New

"So, everyone is here, correct?" Sarutobi asked, looking around the room filled with a few special Jounin and all the ANBU squads in full gear, masks strapped securely over their faces. Receiving no response, he simply continued as he scanned the room, "Good. I have a few important announcements to make. There are going to be some significant changes coming soon. I wanted to explain them to you first. I recently sent an ANBU captain on a solo mission into the forest of death to investigate a weird energy flow that I sensed on this past full moon. The discovery is very intriguing, and I think it best if he explain the findings himself. Kakashi-kun, if you don't mind."

The silver-haired ANBU captain stood lazily from his previous position on the floor next to the Hokage and regarded the crowd for a moment with his one visible eye before addressing them; " I found what was explained to me as a portal to another world. There was this swirling blue mass in the woods, and when I approached it, it pulled me into some sort of house with a group of people that were…dressed and acting very differently from our own ways. They seemed a little surprised to see me but were not hostile. They apologized a lot because they thought that they had pulled me forcefully into the portal, instead of me walking through it on my own."

"Are they affiliated with the new enemies that we have?" Genma asked his captain curiously.

"In a way. They told me a lot of different things, many of which were very hard for me to understand, as they were so foreign. Apparently these new people attacking are not people at all, but demons from their world.

These demons are apparently a great source of evil in their world, but they were losing the battle, so they created a portal into ours. Here they hope to either take over our world, or in it gain the power to take over their own."

"So that is why they have no chakra signatures, yet still manage to complete very strange jutsus…" Shisui's voice faded from beside him as Itachi focused on a weird disturbance he'd been feeling. There was something there, he just couldn't pinpoint…there! He quickly drew a kunai and flung it faster than anyone in the room could notice. No one even knew the boy had attacked until they heard a scream. Blood poured from midair for a moment before three girls and a man appeared, one of the girls with a kunai protruding from her heart. The man quickly wrenched the blade from her chest and held his hand over the wound, healing it instantly.

As he did so, the rest of the shinobi threw their weaponry, and kunai and shuriken filled the air. However, before they could reach their destination, a longhaired brunette in the group flicked her wrists and the blades stopped in mid air. The redhead who'd been stabbed stood up straight and looked around the room, "Alright, who attacked me? This was a new shirt you know. Now it has blood stains!"

The Hokage ignored the girl and addressed the Nins before they attacked again. "Relax," he ordered harshly, motioning for the newcomers to move out of the path of the weaponry. "These are Kakashi-kun's friends and will be our guests for a while."

"That was quite the welcome. I can really feel the love in this room…and it wants to kill us," the shorthaired brunette commented pointedly to her sisters as she stood next to the Hokage.

"Don't worry. Everyone, I would like you too meet our guests from the other world: Piper, Paige, Leo, and Phoebe," he announced as he pointed in turn to the long-haired brunette, the red-head, the man, and the other brunette next to him.

"They are going to be working with you in hopes that they can better educate you about our new enemies and how we might be able to defeat them. You are all going to spend the day training in your cells, and the girls and Leo will move around the groups and try to give you some basics. There they will explain the situation more clearly. The four special Jounins in the room will form their own cell. I know you four are not fond of working with others, but I believe you capable none-the-less. Also, I am going to be doing some slight team rearrangements. Being as Kakashi-kun has already become familiar with the girls and been to their world, he is being reassigned as their personal liaison and guide when in our world. Taking his place as ANBU captain of Cell 3, I am promoting Weasel from that same Cell. Uchiha Itachi will now be that Cell's captain. Also, ANBU member Sumako Hayte is out of the hospital and will be joining that Cell as its fourth member. Now, go out to the training fields and I will send your new senseis out shortly," the Hokage commanded his men.

As soon as all of the shinobi were out of the room, Piper turned to the Hokage, "Are you sure this is a good idea? I'm not comfortable putting them into this. It's not their fight."

"A shinobi is a tool to be used for the betterment of their village, no matter the personal costs. Anything that threatens their village is their fight, and they would be highly offended is you insinuate otherwise, especially the ANBU," he reassured them sternly. "All they need is an environment where they can adapt their skills to fight the new enemies, without fear of dying and they will be fine. Trust me."

The quartet shrugged and followed the old man out into the training grounds, where the masked ninja and four Jounin were all split into their separate four-man Cells. The ladies and Leo nodded to each other and each headed off to a different cell.

Phoebe walked to the newly formed Cell 3, and had a seat on the grass, motioning for them to do the same. With a nod from their newly appointed captain, the four ninja sat with the witch.

"So… I guess we'll start with any questions that you may have," Phoebe offered, smiling kindly at the masks.

"How is it these demons look like people? Demons are great beasts with immense power. It takes hundreds of shinobi to even fend off a demon, and even then they can't be destroyed," a man to her left asked.

"Well...wait. First off, what should I call you guys?" Phoebe asked.

A member who Phoebe recognized as the new captain, Itachi, pointed to each member in turn, ending with himself, " Monkey, Frog, Hawk, Weasel."

"Alright, well, like the Hokage said earlier, I'm Phoebe. So...demons…where to begin? Demons are a lot different in our world, and come in a wide variety of shapes, sizes, and powers. They don't all look human, though most have the basic two arms two legs thing going for them. So an important distinction to make is the upper and lower level demons. Lower level demons often don't look completely human, like they might have scales or green skin or something along those lines. They are usually less powerful and also less meddling. The often don't bother us unless they are working for an upper level demon. They just like to do their thing and move on. Yes?" Phoebe acknowledged Frog.

"What is their 'thing'?"

"It depends. Some are scavengers that feed of the kills of other demons. Some feed on souls, others on anger. Some will never even leave the underworld, which is like the demon area of our world. It can only be reached via spell of magickal transportation. Anyways, next we have upper level demons. Usually they have a human form and a separate demon form that they shift between. But they will always bleed red, no matter what form they are in. They are much stronger and more difficult o vanquish. Many of them require a spell or potion to actually kill them. They are a lot smarter and will often times live and blend in with the mortal world. Any questions?"

"How do you kill them?" Weasel asked.

"It really just depends on the demon, which is what makes it so difficult. We always rely on magick to vanquish them, and I really don't know how it will work for you. Decapitation and dismemberment are usually pretty safe bets, but not surefire guarantees. Really, if you get attacked, your main focus should just be on getting away and back to us and being able to describe the demons and their powers. That way we can look them up in out Book of Shadows and figure out how to vanquish them."

"What is this book?" Monkey asked.

"Well, it's an ancient family text that contains tons of information on pretty much anything magickal. It's full of spells, potions, and magickal creatures."

"What are these powers you keep speaking of? And these spells? How do we do them?"

"Well, you don't. Spells are invocations of magick and energy that have to be spoken by something magickal, such as witches, which are what me and my two sisters are. Powers are kind of hard to define, so I'll just give examples. I have the powers of empathy, premonitions, levitation, and fire throwing. It just means that I have the innate ability to do them and they don't require any special activation, or energy expending. The whole 'weapons frozen in mid air thing' from earlier was Piper's power of temporal stasis. She also had molecular combustion, which is blowing things up, and conjuring, which is the ability to make something from nothing. She just thinks about something and can make it appear. It's a new power though, so she can't control it completely yet. Sometimes things just appear in her hands or near her…it's really funny. Also, you should know, our powers are tied to our emotions, so if we get particularly angry or upset, they can get a little out of whack. As far as what you might see from demons, the most common powers they have are energy balls, fireballs, and shimmering or flaming, two types of teleportation. Basically, one minute they are in one place, and suddenly their body shimmers/flames out and into another. It's the same as orbing, which white lighters like Leo do, only the disappear and reappear in blue and white lights."

"What is a white lighter?" Monkey asked despairingly, trying to keep up.

"A white lighter is an angel. They are people who did a lot of good when they were alive, and after death they are assigned to watch over future white lighters as well as witches and other good magickal beings."

"So he's dead?" Frog asked, voice similar to Monkey's.

"Yeah…Leo's a long and special story you really don't want to hear about right now. Why don't you tell me some about this world now? We have ninjas in our world...but somehow I don't think they are quite comparable."

Hawk, who like Weasel had been mostly silent decided to answer, especially since he knew Weasel wouldn't, "A shinobi is a tool used for the betterment of its village and people. They have no emotions or other things. They follow orders to the best of their abilities. There are several different ranks of shinobi. Most children graduate from the academy at age 13 and become Genin, the lowest ranking. There they form into their first three man Cell and complete easy missions under the watchful eye of a Jounin instructor. After Genin, the age at which each level is achieved is dependent on the individual, and there is no guarantee that anyone will reach the next level. Chunnin is the next stage up. Here you will be given more difficult and sometimes solo missions, or may be assigned to other areas of work in the village. After that is Jounin, followed by either Special Jounin, or ANBU. Special Jounins are members that would rather complete solo missions and other activities than join the ranks of ANBU. ANBU is a special tactics team that answers directly to the Hokage and are responsible for his well-being."

"Wow. So, what kind of training is it?"

"Taijutsu, which is hand to hand combat and weaponry, Ninjutsu which is the use of special techniques similar that to me seem similar to your magick, except that anyone could potentially do any of them, but they require different amounts of energy. Also we train in genjutsu, which is the art of illusions. We accomplish all these things through the use of chakra, which is a like a life energy that flows through us. We can manipulate it by concentrating it through hand seals to help us with out jutsus. Like you stated before, it is hard to explain."

"That's so amazing. Don't you think you guys start a little young though?"

"Not at all. 13 is only the average age. There are some who compete these tasks at much younger ages then others. We usually refer to them as geniuses. Kakashi-sama is an example of one, as is Itachi-sama. He graduated from the Academy when he was only 7, made Chunnin at ten and ANBU at 12, and now he's only 13 and an ANBU captain. HE also mastered his clan's blood-line limit at age eight, an age at which most members of the clan can't even activate it."

Itachi sat by passively as they talked, absorbing and processing all he had been told. He ignored most of the conversation about him. He was used to being bragged about, and as much as he disliked it, it would happen anyways. At least with him there he could control the words being said somewhat.

"What is a blood-line limit?" Phoebe asked curiously.

"Well, it is kind of like your powers I guess, in that not everyone can do it. These limits are specific to certain clans, or bloodlines, and even so can't be accessed by every member. There are many different limits though, and not every clan has one. The Uchiha Clan has the Sharingan, a doujutsu, or eye technique that allows one to copy things. Pictures, faces, and the like, but more importantly, the users can copy their opponents hand-signs and chakra flow, allowing them to perform any technique that they see. It also gives the user the ability to see things right before they happen, like a small flicker of the immediate future, and they can also follow chakra patterns. There are other things too I'm sure, but Itachi-sama and Kakashi-sama won't tell us those."

"I thought Kakashi's clan name was Hatake."

"It is. You notice he always has one eye covered. That's because the covered eye is a Sharingan eye given to him by his best friend Uchiha Obito. Obito died on a mission, but as he was dying he had their third team member Rin transplant one of his eyes to Kakashi. The Uchihas hate him for it. They are very jealous of their eyes."

Phoebe glanced curiously at Itachi; surprised his subordinate would talk so openly about the boy and his clan in front of him.

"Itachi doesn't care much. Well, he does, but he likes me well enough not to hurt me for saying such things. Well, at least not enough to kill me. I'm sure that there will be some training accident, or I'll wake up missing an arm or something like that, but it's okay."

"This is a very interesting place," Phoebe commented, looking around at her sisters and brother-in-law.

A/N: So…this chapter was a lot of info, I know. Don't worry if you didn't get a lot of it…most of it will be explained again later.
