I do not own Naruto or any of the powers I use in this story I just had this Idea for a while.
I opened my eyes to see a blindingly white being standing in front of me. When I looked down I realized that I was now nothing but a soul, with no body or form.
"Who are you, and where am I?"
"I am what you would call a God, though I am one of many." the being said
"So I died?" I thought "Well what happens now?"
The god looked slightly surprised.
"What?" I asked
"Nothing, It's just, everyone normally freaks out at the revelations they experience in meeting a god and finding out what happens after death or about their death."
I mentally shrugged, "Well I'm dead and gods exist that's one thing I knew and one thing I didn't believe existed. I guess it's kind of cool, but it doesn't matter now that I'm dead. So am I going to the afterlife or what?"
The god looked contemplative, "Most people are reincarnated based on the karma they have collected during their life." they said looking through me, "You have done your fair share of good and bad throw-out your life, and it seems you really turned it around and dedicated yourself in at least being a good person and helping as a doctor." he said looking contemplative. "here's what I'm going to do, I can't overlook the bad you've done before, and I can acknowledge you turned your self around. So here's your situation. I'm going to reincarnate you into the Naruto Universe."
My eyes widened in surprise. "Isn't that universe an anime and not real?"
The god chucked. "You humans don't give yourselves enough credit, while your world has no supernatural elements, your imaginations are enough to spark their own universes. Anything any human has ever imagined, from a child's make-believe world to every anime created is real. Once the "Series" ends It becomes independent and the beings create their own universes, as it continues forever.
My head swelled from that information and I became slightly excited.
"As I was saying, you will be reincarnated in the Naruto Universe however you will not have your own body. You will be a guide to Naruto Uzumaki, A separate soul inside his body. With that your bad Karma is exsolved."
"And what about my Good karma?" I asked slightly hopeful."
"You've accumulated enough to have three requests granted. I cannot change your bad karma, but, anything else you want including other universe powers are available to you."
My mind whirled with possibilities. No limits, anything I wanted. "Can I eventually create my own body with one of my wishes?"
The god read my mind, or that's what it felt like, and exuded energy that felt like a smile. "I'll allow it."
"Then my first wish is all Naruto fanfiction that adds new Jutsu, bloodlines, and techniques anything I can remember will be available to anyone in the universe if they create it including me. For my second wish, I want to use all the magic from Undertale and Glitchtale within Naruto's body, converting chakra into magic, and give anyone a spark to awaken their own ability. And my final wish is to absorb all of the tailed beast's chakra and eventually become my own ten-tails with my mind intact.
The god, in my opinion, felt impressed at the seemingly thought-out wishes. "Alright then, good luck with your new life and if you do get to that point I'll allow it.
My eyes widened at the implication the god gave me. "You mean-"
"Yes If you do make it that far I'll allow it."
My heart flutterd in excitement and I felt a smile grow on my soul.
"This is going to be fun." I said as everything went white.
