Some time ago-
You're currently having a very unusual time, and for you of all beings to say something is unusual, well . . .
You, mightiest child of the Sage of Six paths, curled your fingers as you flex your hands. The sizzling holes bored through them by that woman's seal still ache deep in the many bones within despite their nature, or maybe because of it. For all that your flesh is made of chakra instead of meat it is still flesh, of a kind. But it is a meat made of chakra, a body manifest by will and power and the legacy of the greatest man to have ever strode the earth.
The Nine Tailed Fox does not see the sky when you look up, but you can feel the moon as it hangs above the earth, still dormant, not reborn. It is there. It has always been there since the day of your birth, up until those red eyed fools released what was inside it. Even from inside your prisons you could feel it. The hate of the ten tails still clings to that lifeless rock like the stench of a rotten corpse. Even in the cruelest or strongest of your prisons, beneath that woman's cruelty or the brat's cage, you could still reach out and feel the horrific wrongness contained within.
Since that woman was alive, you must be in the past. This gives you options, but . . . you're not a very productive bijuu by nature. Everything changes too fast to get worked up about, anyway.
You could wake Naruto, the cocksure boy, but that was the problem, wasn't it? Naruto and that other one he refused to let betray him had stood against Tobi, then Madara, and then the Ten Tails and then they stood against Kaguya with that same refusal to bend that children always had. And somehow, miraculously, your former prison had inherited more than a philosophy from the Sage's favored son. He stood against divinity even as Sasuke -that was his name- found his own ancestor's power and all the rest joined him one by one. They built around his tower, shored him up, and he became a wall that could stop even a being so great that Kurama was a mere part of her, a scrap.
You reached deeper into yourself than ever before, brought forth chakra and techniques even you didn't realize that you was capable of, and . . .
There weren't enough of them.
For every shinobi you lent your chakra to, or that reached new heights of their bloodline in desperation there were two trampled in the dust by the struggle to stop the succession of monsters they had gathered to face. It was the last Shinobi war, and no matter who won, the Shinobi lost. Tobi and Madara's obscene eyes were too powerful a gatekeeper to pass without paying a hefty toll. Too many of Naruto's allies joined their heroic ancestors in the pure lands or sealed away, out of reach of even the most forbidden techniques.
And so when Kaguya grew tired of dueling with the sages arrayed against her, she threw them aside into another dimension and made a mockery of Naruto's promises to protect his precious people.
Your chest grows hot with emotion and you dig your claws through the glass floor, digging great trenches in it before you regain your calm. She made a lie of his attempts to create peace -bar one.
One spark struggled on as prison and prisoner both meditated and searched for a way back to help them. Naruto's face was wet with frustrated tears and his voice was hoarse, but his eyes were resolutely closed. His breathing was steady. Even separated by all of reality, you could feel your own chakra invested in that single spark. It was you and you was it, and through that connection that stupid, precious child could feel that there was still someone left to save.
So focused were they both that they felt the exact instant it was over. The spark flickered, guttered, and for a moment you thought you felt the veil between dimensions strain as Naruto bent all his effort on that single barrier between him and the person screaming his name, and that person reached across the gap to him. Their chakra was fading, their respective kinds of Sage Mode finally taking their tolls . . . and . . .
They didn't deserve to die alone, not these children. Whoever that other human was, they didn't deserve this.
You pulled on the cloak of power still attached to the dying brat, and now instead of two disparate chakras pulling on each other there were three merged energies trying to snap together.
Then you woke up in front of a whole village full of sharingan eyes, did the smart thing, and left.
So you're in the past as yourself, in your full and undivided form. You're twice as powerful as you were when divided, know enough about what might happen to make your head hurt, and the only human you give a damn about on a personal level isn't going to be much of a help for a while yet. You're currently a mile underground in a deep cavern with walls of thick glass, hollowed out with the heat and pressure of your chakra. That woman is still alive, unfortunately, but so it Tobi. Madara has yet to rise from the grave, those of your siblings still alive are imprisoned, and that blond Hokage is still alive too, you think, because when you snapped back to yourself you broke Tobi's control.
If you see that masked Uchiha again you'll tear out your own eyes instead of risking falling under his sway. They'll grow back.
Overall . . . you lift your lips to bare a mouth of vicious fangs. You can work with this.
You'll let Naruto rest for a while.
There's no hurry.
But when you wake you'll have justice at long, long last. Now you just have to decide who deserves to taste your anger first, that woman or that man.
Deep in the bowels of the earth, the Kyuubi slumbers. But where shall we look next, forward or back? Forward will be best, I think. And this might be the last of the travelers I show you for now. Perhaps. Maybe. I need to keep some secrets, right?
