The Third Hokage's Office
Five Years After the Kyuubi's Attack
You were not expecting to be told that your were a centuries old chakra monster that morning, that was for sure. At most, you had expected a stern warning to behave in the academy from the old man, the venerable hokage having grown more and more distant in the last few days. At first, you had pushed the hurt you felt at his coldness by telling yourself that he was merely busy with your enrollment as an academy student, but you knew better now. He had been steeling himself to tell you the harsh truth of your existence, of your future in this village.
Your tiny fists turned white as you gripped the edge of the wooden chair you usually favored, strand of crimson colored hair obscuring your suddenly blurry vision as your felt your face twist in a ugly grimace displaying the grief and vulnerability you were not able to hide. In the last five years, you had tried to fit in to the best of your abilities. It hurts to suddenly be told that being liked would be forever out of your reach because of a previous life you did not even remember. It hurt, it made you angry... it made you cry. Right now, as you roughly wiped away the stray tears that had escaped your eyelids, you felt lost and alone and did not know what to think. You were just a kid and you felt nothing like an all powerful tailed beast in this moment. Expecting you to just go along with everything was unfair!
As you were about to voice your frustrated thoughts, a weary sigh from old man Sarutobi made your head jerk painfully upwards towards the noise and elicited a pained cry from your lips. You had nearly forgotten about the Sandaime's presence, and felt a deep blush stain your pale cheeks at your forgetfulness. You shook your head free of thoughts and decided to hear what the old man had to say for himself, as maybe there was even more trouble in the horizon for you.
"Kyuubi... I sincerely hope that what I saw in the last few years was not a ploy on your part to lower our guard, and that you are sincerely willing to turn a new leaf with this village. I understand that it is easier said than done, but working willingly as a tool for this village would bring you far more fulfillment than plotting to destroy it once more. Yes, you will be used, but in service you will find a new purpose. Should you be genuine in such purpose, you will have a place among us." He looked old when he said that, but the alternatives he told you about as his face turned into a fearsome mask made you certain that the legends surrounding his being called the 'God of Shinobi' were not to be dismissed lightly.
'I have to say something, but what?' You thought, you mind buzzing sluggishly as it usually did when you were faced with something you could not simply talk or punch into agreeing with you. As the leader of your village looked down upon you sternly from behind his imposing desk, you finally found the resolve to say...
[] (Truth or Lie) Write in speech, it must involve what you want to be called if not 'Kyuubi' (Please no Kurama, as his memories are gone for now), as well as any intent you may wish to declare. Do remember that his chakra is mostly Yang natured due to the sealing of it inside the Shinigami and so his reasoning abilities are flawed to say the least despite the Yin slowly coming back due to the remnants of Naruto's chakra. You can go in many directions from here, and it's your first chance to craft how the MC will act from now on.
Yes, it's surely confusing as an intro, but I will be giving more and more information about this 'new' setting as time go by. For now, just know that this is my take on the few 'Kurama/Kyuubi is reincarnated in Naruto's body due to the Yondaime's seal' fanfics I like so much. In this case, the MC is different looking from Naruto due to the heavy changes done by Kurama's chakra as he was reborn inside the infant body of his failed host. Pale skinned, red eyed and haired, and utterly normal for now mentally except for the chakra imbalance. That normalcy will not last, as we are talking about both a literal chakra beast and SV, but for now we are in the Mook territory.
