I do not own Naruto, unfortunately. Only my oc and bits of the plot are mine. Please enjoy and if you are a beta and wish to help with any flaws you may see in the flow or anything in my story, please pm me.

Ages are as in cannon. Team Minato has only been a team for approximately a few months. Kannabi bridge mission hasn't happened yet.

Biju "Little brat, insolence will get you nowhere!".

Mind link (Ok, here's how we're going to do this.)

Please keep the hate to a dull roar.

The Uchiha clan was under attack. As Obito ran towards the clan heads house, all he felt was a sense of dread in the pit of his stomach. Kakashi and Rin weren't far behind him, having followed Obito as soon as he took off toward the compound as the first explosion rang through the dimming sky. All Obito could think about was his four-year-old cousin, Itachi. Itachi being way too smart for his age and knowing how the rest of the clan sans Mikoto and Fugaku treated him. He had to make it, it wouldn't do for him to fail one of the few members of the clan he actually liked being near.

As soon as he opened the door to the clan heads house, his blood ran cold in a frozen fury as finally his sharingan awakened. Itachi was unconscious in the arms of an Iwa shinobi. He needed to get Itachi away from the Iwa ninja. Only one jutsu came to mind. Well, at least he could trust Kakashi to catch Itachi if this worked. Barely acknowledging his teammates behind him he used the first jutsu that came to mind to retrieve Itachi, the substitution jutsu. That's when everything went dark.

Unknown pov

They brought in another one today. A boy this time. He has the black hair and pale complexion of a typical Uchiha, well, except for the orange goggles around his head. They were talking about sealing "it" in him. I guess they think since he's Uchiha he'll be able to survive the sealing long enough for them to brainwash him to be a mindless soldier like the rest of these blank masked freaks that call themselves root. I don't know who their leader is other than they call him Danzou-sama. I wonder which boss summon they will try to seal into the poor boy. Well, one thing's for sure, I'm not letting them turn him into a mindless monster. If he lives, as soon as he can walk, I'm breaking us out of here.

Obito's pov

Everything hurts. Ever since everything went black as I switched with Itachi it hasn't stopped hurting. It feels like my insides are being ripped out and put back in again. I'd scream, if I could, but all that I can do is try to catch my breath and hope I fall further into unconsciousness so I don't feel the pain anymore. After a while The pain subsided and I could hear "The procedure was a success. Place him in the room with 'her'. Alert Lord Danzou of this development.". I try to move but find I've been bound. I still can't see so it's safe to assume that I've been blindfolded.

"Test subject number Uc10 has awaken, shall I administer the tranquilizer?" Oh God they're going to put me under again! "Proceed." I struggle in vain to stay conscious as they stab me with what I assume is a needle. The last thing I hear as I lose consciousness is "Put subject Uc10 in with subject Uz01." "Isn't Uz01 the only living subject other than this one that we have anyway?" "It doesn't matter, do it anyway."

Subject Uz01

I awoke to find a body in the other for in the room with me. At least it isn't a corpse this time. I go to take a closer look and realize that it's the boy they brought. Maybe I can have a friend in here after all. Granted, he is the only breathing person near me who isn't one of my, I mean, our captors. I guess I'll sit and meditate until he wakes up.

-mindscape-

I open my eyes to the familiar visage of my mindscape; a rolling valley split in half by bar's with the kanji for seal on a gate mid-way through the bars. Behind the bar's lays the yin half of the Kyuubi No Yoko, or as I call her, Kura. It used to be a sewer but since we've been each others only company for a while now we've become sort-of friends now. "Kura, wake up. They brought another in. This one survived whatever boss summon they sealed in him. He looks to be Uchiha.". She opens one huge red eye "Really now Kit. It seems things will get interesting around here again". "You sound bored" I say. "Do you think you could find out which boss summon was sealed inside him?". She looks contemplative for a moment, then closes her eyes and a red aura appears around her for a minute. The aura subsided and she opens her eyes to say "This is going to take a while Kit. He's waking up though I'll tell you what I find as soon as I find out. Maybe you can get this kid to give you some clues as to what exactly we are dealing with here. We need to convince it to work with us if we are going to escape from here.". I nod and proceed to leave my mindscape just as I start to hear movement from the other side of the room.

My vision returns slowly, black spots receding slowly as I blink, taking in the surroundings. I seem to be in a bare stone room with a small barred window in the steel door. When I try to look closer it seems to also have a slot in the bottom for something to slide under. There's a small window near the ceiling on the opposite side of the room and another cot with a white haired girl with red eyes sitting on it. She appears to be about one to four years of age and is dressed in a grey ragged dress like thing. I try to open my mouth to say something, but find that I can't make any sound come out of my throat, other than what sounds like a low rasp. She looks surprised for a second, then her expression quickly morphs to one of contemplative sadness.

"I can't fix your voice at this time, but I do know a way to secure an alternate way for us to communicate. It will link us together though. Just nod if you are okay with this.". Her voice sounds soft like rose petals yet fierce like an ocean storm. Its beautiful. I nod as enthusiastically as I can and she proceeds to get off her cot and walk over to me, then bites into her wrist and holds it over my face. "Drink" she tells me and as I open my mouth to protest, shoves the bleeding wrist into my mouth. As she forces the sickly sweet liquid down my throat I begin to feel strange. Removing her arm from my face, she wipes the excess blood of a surprisingly already healed wrist.

"Don't worry that's just what the linking is supposed to feel like. Now, try to talk to me but simply direct your thoughts in my direction.". I looked at her confused. (Direct my thoughts? Like this?) I ask. (Yes, exactly like that. Now that we can communicate in private, we can discover who or what exactly your tenant is.) she 'says' back. I Just stare at her, shocked. She just sighs exasperatedly and explains. (When you were brought here they sealed some sort of summon, a boss summon specifically, inside of you. Its probably why you can't speak seeing as a sealing process even at our age is excruciatingly painful.) I gape for a minute. (Our age! How old do you think I am you look four years old!) I exclaim. She laughs, sounding like twinkling bells, (So do you. They are experimenting on us after all. Apparently it's de-aged us to toddlers)

(You mean i'm-!) I start (Yes that is exactly what I mean and until we can get whatever they sealed into you to work with us, we can't escape this hellhole.) I look at her, confused at this. She gives me an exasperated look and says (It's the reason you were brought here. They took you and sealed a boss summon from a summoning contract inside you similar to how someone like me has a biju sealed inside them. I have the Yin half of the Kyuubi. We need to find out what or who is sealed inside you and see if we can get them to help.)(Them? What's a Kyuubi?) She looked at me confused for a second like what she said I'm supposed to know about what she just said. Bijus sealed inside people?! And she's telling me she has one just like telling me the weather? On top of her telling me I have some sort of boss of a summoning contract inside me as well?!

She waits a second before continuing. (There are nine biju; ten if you count that the Kyuubi has been split into the yin and yang half. The biju normally are sealed into people called jinchuriki or the power of human sacrifice. Whoever these people are, root or whatever they deem to call themselves, have acquired summoning contracts and apparently somehow sealed the boss in you. You are the first one to survive the procedure. I don't know why they keep me here. They sealed our normal chakra but I noticed they didn't or can't seal theirs. We can use this to escape but I can't do it alone. What do you say, are you in?) Too stunned to speak, I simply nod.
