This story is based off of the concept of the Fullbring and Hollows from Bleach, centered in the Naruto universe. In this story, the Juubi was a Hollow powerful enough to split off and create it's own dimension, known now as the Elemental Nations. I will not be including Kaguya or her ilk in this story as this story, or at least the idea for it, was conceived likely before she was.
Pride
Naruto looked at his hands disbelieving of what he saw. Had he really just done that? Gaara lay on the small mountain of sand with burns covering parts of his body, a glass wall perforated with holes the only thing that lay between him and the one who fired off the attack.
That sudden burst of anger and... hunger? Is that what that was? That burst of emotion in Naruto resulted in him pointing his fist at Gaara. From which a burst of red energy came blasting out. Gaara brought up a shield of sand in time to block most of the damage, but a few jets of whatever it was managed to pierce through the wall, melting it to glass in the process.
"No"
The rasped word was just loud enough to be heard by Naruto, who put aside the strange attack he had used to focus on the source of the word.
"No, my existence will not end." said Gaara.
He stood slowly, but found himself unable to do anything else. He saw Naruto walking over and began to panic. He couldn't even move his sand to protect himself. Naruto stumbled slowly closer and raised his hand. Gaara closed his eyes, expecting the same attack as before, but instead he found a slight weight on his shoulder. A hand. He opened his eyes to see Naruto right in front of him, softly smiling.
"I used to be like you, you know. Eager to prove you exist by raising yourself above others, only when you feel like you're nothing the only way to make yourself above others is to put them six feet under. I did that once. A man broke into my home and was prepared to kill me, had the knife right at my throat. He was a baker. I was still stronger than him, though not by much, but it was all it took to beat the life out of him. Once the adrenaline wore off i was horrified at what i had done. I always avoid the part of town that his family lives in to this day. The point is, i don't know what happened to make you so jaded towards death, but i know that feeling of vindication that comes with coming out on top in a situation like that. You let it consume you though. I had people to pull me out of that darkness, and those are the people I fight for. It wasn't my power that you lost against. It was the power of the people who kept me going, that you lost against."
With that, Naruto let go of reality, and fell into unconsciousness.
