Author's Notes

Hey, so i'm not really a writer and i'm not pretending to be one, but I have a wild imagination and I just want to see what I can do, whether anyone actually likes this or not doesn't really matter, however I am open to constructive criticism as i'm sure it will help. If you are not aware this story is a Naruto x Demon Slayer kimetsu no yaiba crossover, which takes place at the begging of Demon Slayer and towards the end of the Fourth Great ninja war in Naruto.

I haven't considered any paring's mostly because I feel they don't really fit into the Demon Slayer universe, However I might consider just having some Naruto characters move over for it, only if it I really feel confident in writing it in.

Anyway that's all I have to say hope you enjoy

Chapter 1

Where am I and what's a Demon?

.

.

.

Blood spread from a newly open wound, pain evident, even through the foggy haze that was no doubt death, and in that moment a life quite literary not yet lived flashed, lost soulless eyes, practically begging for some sort of forgiveness for their sins; hoping to enter at least a more friendly afterlife.

Looking down at the decaying body of a demon is always a fascinating site, even those who didn't know what a demon was exactly might find some part of the process intriguing; you know as much as watching someone die could be intriguing, and even though most demons could regenerate limbs within moments, "killing" one over and over until the sun came up would eventually end their life in a blazing glory of quickly burning flesh. That or you know the demon would somehow be smart enough to notice the sun rising, and by chance somehow be resourceful enough to find shelter. Other than that of course this particular demon wasn't so lucky as its body was quickly becoming nothing.

Two hands brought together and a head tilted down in a small prayer would be the only form of redemption the demon would be given, even if it would not be able to show how grateful it should have been and was unaware of the small kindness shown to its otherwise terrible existence.

Of course speaking of the person giving the small prayer, being of about 5'11 which seemed be almost appropriate for them, not to mention tan skin which seemed to almost glow as the sun licked at it, the person wore from bottom to top; black steel toed boots from which black slim fit cargo pants were tucked and wrapped around the thighs seemed to be two small pouches with a dark orange tint for the wrappings. Moving up the person wore a black long sleeve shirt with two orange strips at the ends of either sleeve, and a red swirl like symbol rested over their left breast, over the shirt sat a burnt orange haori with black flames licking the sleeves and the bottom, on the back of the haori were the kanji for "Hero of the Hidden Leaf", moving on to the persons facial features where three whisker like scars rested on ether side of their face, blue eyes as deep as the ocean and finally rested on their head was almost pitch black hair that seemed to suck in the light if the sun with crimson red almost floating as highlights, whether that was dyed or natural remained to be said.

And finally resting softly within their hands was a Chokutō, still dripping with the blood of the recently deceased demon, This person as you might have guessed by now, considering you're reading this; is named.

Naruto Namikaze Uzumaki.

And right now he really wished that it wasn't

"Dammit Sasuke" He spoke aloud hoping by merely mentioning the lighting wielder he would become the element he controlled and appear before him in a bright flash of brilliance.

"..."

Silence engulfed the forest he was in and to him it felt almost suffocating. Unfortunately Kurama and the other bijuu were probably still sealed in a giant ball of chakra so he couldn't really try and reach out to any of them, for once Naruto Uzumaki was at a loss; in unknown territory with no one around and little to almost no information other than that he was in a Forrest, he really didn't know what to do, Hell he barley remembered what happened!

Still, he had to do something, staring at the sun Naruto made up his mind, first thing first, he had to find a place with people who wouldn't attempt to kill him as soon as they saw him, maybe see if he could get any information off them. Looking at the sun getting slightly higher in the sky, Naruto turned away from where it would be around noon, getting a rough idea he decided north was his best option and started walking with one thought running through his mind.

"What the actual fuck".

Well maybe it wasn't so much a thought more of a statement.

As Naruto made his way, watching as the sun rose in order to adjust his path to a more true north, he considered just attempting to travel by trees but he wasn't sure how anyone would feel seeing him casually jump leaps and bounds from tree to tree, not to mention; he couldn't feel any chakra within him, almost as if it all but disappeared, which was an odd thought because one if that were to actually happen he should be dead and two; considering he had the most chakra in the elemental nations, the mere thought that he could run out was absurd. Closing his eyes and putting his body on auto pilot, Naruto took a dive into his mind attempting to see if he could find some answers within.

He opened his eyes to a sea of darkness, illuminated only by torches that were placed within the walls and even then those were few and far between, he glanced down at the water that permeated the sewer that was his inner world, ' huh I wonder if there was every anyway to change this' he wasn't too sure, Kurama never spoke of anything and he almost seemed content with simply lying behind the gates even when they had become partners. "maybe I should change thing's up, if Kurama ever wants to come back" he spoke aloud. Though he wasn't even sure if he would see his friend again much less anyone from the elemental nations.

He paused his walking, staring at the red gates that no longer housed a giant orange fox and wondered for a second why the gates were still there. 'Heh yet another question that has no answer'. He look over at the pipes that would represent his chakra and observed the lack of a faint glow to them, he walked up to one and put his right hand against its metal surface, noticing how uncomfortably cold it was not to mention the lack of movement within them.

His chakra coils were still present it seemed but as far as he could tell they served no purpose at the moment. Naruto really had to take that information in for a few moments...'no chakra?'

What happened to his chakra? Why was the seal still present if he basically had no chakra to supply it? Why were his coils still present when nothing flowed through them? And why the heck was he not dead?

So many questions brought up in here, and all he wanted was answers.

Opening his eyes to the real world again he was surprised to find the sun high in the sky above him, more specifically he was now in a snowy forest instead of a regular one "it must be winter then" he concluded " I wonder if i'll some type of caveman here or a super technologically advanced civilization" He almost laugh at that, he didn't see any flying trains or anything like that, Hell he'd be lucky if he found a normal train. taking one more glance at the sun he took placed his hands over his eyes and squinted as if magically something would appear before him, and call him Kevin, there it was, it was faint; but he could definitely see smoke over the tree tops " looks like my lucks looking up!" with that said Naruto practically sprinted to the smoke, with any luck whatever civilization he came upon would at least be out of the stone age.

It took nearly until nightfall before Naruto could even see the gates that surrounded the small village and he had to wonder if that creature that had attacked him last night would somehow regenerate and come looking for him, ready to intact vengeance upon him. He banished that thought from his mind, even if it did he'd at least be ready to just tie it against a nearby tree and wait till sunrise again.

Speaking of the sun it was nearly set and while Naruto never really minded the cold, right now with his lack of chakra, being exhausted from the war, his battle against the creature and his mad sprint to the village he was barley able to see were starting to add up and he was really hoping for a warm futon if he managed to gain entrance into the village, which; by looking at the now closed gates was probably not going to happen tonight.

Giving a sigh of defeat at the missed chance he resigned to setting up a small camp with the little supplies he had, which was odd that he had any to begin with, for some reason while the seals on his body couldn't be removed and they didn't even work with chakra, but when he had smudged some of his blood that was on his arm from his battle with the creature that wouldn't die, the small storage seal that was on his arm activated and released a good set of supplies, a tent, a sleeping bag, some rations, and to his surprise Gama-Chan. He had tried returning the items into the seal but it appeared to be a one time release so he wasn't too keen on letting the others on his body get released, least he end up having to actually carry everything around
"Kami I miss my Toad scroll" he muttered his person, 'that thing could carry so much ramen'. With that thought he considered drifting off to sleep, he refrained of course, for one he was too dam cold and two his shinobi instincts were telling him falling asleep in unknown territory was probably not a good idea, at least no until he got that warm cozy futon he so longed for.

With that he just laid there against a large tree, terribly uncomfortable and horrendously cold, and it was with that he bitter thought it greatly resembled his early childhood. He just hoped nothing would happen before the sunrise.

Not too late did Naruto feel every so stupid for practically screaming at lady luck for him to have an uneventful night, she didn't seem to like that for, as soon as the moon was high in the sky Naruto found himself moving out of the way of two clawed hands aiming for his neck.

"Well great" Naruto spoke aloud and looked at whoever attacked him this time and was instantly reminded of the other undying creature.

"Guess Lady Luck didn't quite like the idea of me getting cozy, huh?" he spoke more to himself when said that considering whatever was in-front of him did not seem to even humor his existence other than to kill him.

"You know" he glanced at the sword that now rested in his hands. "If I didn't know any better i'd say you are trying to kill me" he laughed at his own joke while the creature only growled at him, angry the seemingly easy food was starting not seem so easy.

"huh, you know what's weird?" he didn't wait for a response, not like there was going to be one. " I find myself less afraid of death here, almost like I don't really care if I die or live." this actually earned him a reply much to his surprise.

"Then why don't you just die! I'm getting hungry" The words came out as nothing more than a crazed, raspy scream, but non the less it had spoken, which to Naruto meant it had to have learned it somewhere that had a set language which at least meant they were past the stone age.

'Maybe I can get some information out of him' Naruto thought and for a moment he considered it, but eventually thought better of it, considering it's only words were, 'then why don't you just die', he probably wouldn't get any info out of it.

He might as well humor the creature, after all; it was going to be stuck to a tree all night.

"I don't know, I don't really feel like dying in some unknown place to some Edo Tensi wannabe" For some reason while that insult made no sense to the demon it still became enrage and proceeded to leap at Naruto, at which Naruto took advantage of and ducked under at tree where he had set up a quick trap with ninja wire.

Hearing a glorious snap and grunt Naruto looked around the tree and up to see his prize. 'easier than I thought' he assumed the chase would be longer really.

"You know" Naruto paced around his prey. "You're as dumb as I used to be" this served to anger the thing more, its eyes trying to kill the human that dare not be its food.

"So i got a few questions, you feel like answering them? I mean if not I'll just start cutting" Naruto pulled out Sasukes sword at this, speaking of which he had no idea how even got it.

The human monster thing seemed to stop its thrashing for a moment as if considering the offer, and Naruto was almost hopeful, of course those hopes were quickly dashed away due to the beast continuing its thrashing even more.

*sigh* "have it your way I guess" .

And for the rest of the night Naruto sat under the tree every now and then stabbing, cutting and jabbing the thing when he asked a question or just if he got bored. He was never too big on the whole torture part of being a shinobi, Jiraiya being a world class spy had insisted that he at least learn the basics, though judging by the small frown on his face; he was unable to acquire any info from the thing.

As the sun was slowly making its way over the horizon; and the tree tops, the undying creature begin thrashing and screaming even more almost begging for Naruto to let it go, knowing its fate as the sun drew nearer.

On Naruto part he simply closed his eyes, clasped his hands together and began to pray for it, and while Naruto himself didn't really believe in a religion, he did believe in an after life though; due to the fact that he had met the Shinigami on a few occasions, each time the Shinigami would get more and more irritated, complaining about not being able to just kill him and be done with it. Something about "Da Rules"kept it from taking his life.

As the creatures body seemed to burst into flames, Naruto would admit; it was definitely and interesting sight. After all he couldn't really remember anyone from the elemental nations just bursting in to flames upon their death. After finishing his prayer for the doomed creature he set his sights on the village.

He was getting some answers, even if they were basic answers, even if he had to kick someones ass for them.

The people of the village under the mountain were simple, non of them really stood out, non of them had any big dreams or aspired to go above what they were asked. all of them, but one 13 year old boi. this young boy traversed down the mountain as much as possible in order to provide for his family and while he was in the village he would help the villagers with whatever problem they might have. It was around noon Naruto could guess and it was this sight that Naruto found to be quite amusing, seeing all the villagers call for his help, it reminded him of his time after he defeated Nagato for his village though probably on a smaller scale here.

This boy is short for his age around 5'4, with rather tanned skin. On his head was ruffled burgundy hair that casts notably dark shadows on itself, combed back to expose his forehead, and wide, dark eyes with white pupils that appear dark pink around the lower section of their irises. He also has a birthmark on the top left of his forehead. He wears a checkered dark turquoise and black patterned haori over a white kimono and thick black pants as well as a blue scarf to protect from the winter.

This boys name of course is Tanjiro Kamado, and right now he was selling coal for his family that lived near the top of the mountain, hoping to get enough money for a big feast and maybe a nice dress for his beloved sister.

Naruto considered him for a moment before deciding that he would be the best option for the questions that he had, hopefully the kid wouldn't think he was crazy or stupid with the questions he was going to ask.

"Hey kid, names Naruto, Naruto Uzumaki, i'm sorta new around here and I wondering if you might be able to answer some basic questions for me". Naruto congratulated himself for a job well done seeing as this kid didn't respond negatively.

Tanjiro turned to look at the onyx headed teenager then he looked up at he sun, the day had really just started for him so he definitely had time to answer a few simple questions.

He quickly responded "Oh nice to meet you Naruto, my name is Tanjiro, Tanjiro Kamado, and i'd be glad to answer any questions that I can". He then gave Naruto a genuine smile seemingly happy to help someone in need.

"Alright but please don't think i'm stupid or crazy or anything for these questions". Naruto gave Tanjiro almost pleading eyes as he stated this and Tanjiro simply kept smiling, after all, what could Naruto possibly ask that would make him stupid, he nodded for Naruto to go ahead.

"So if you could tell me where I am exactly and not just like the village or the land but the world and continent if you can as well as the time period, Oh! and if happen to know where I might be able to get a map that'd be great!. And one more thing, there was these things that were human like but no matter how many times I tried to kill them they wouldn't die,at least not until the sun came out, would you happen to know what that was". Naruto spoke almost to fast for him to follow but he was able to get all the questions.

Tanjiro though he had a smile on his face internally was a bit skeptical, ' I mean who doesn't know what continent they live on!' did he live in the wild? even then he would should at least know what year it was, and what about the last question, some of the villagers seemed to get triggered at the mention that he tried to kill someone and even more so when that someone was stated to not die. He almost felt it odd that this young teenager could kill someone but judging by the sword strapped to his side he could assume he knew how to use it. Regardless he prepared himself to answer his questions.

"Well in order of your questions we are currently part of the Asian continent in japan of the village of the mountain which is just recently in the Tashio era at the end of the Edo period, year 1912, month October, day 16 and I believe you should be able to acquire a map from one of the shops towards the center of the village, I'm not really sure about your last question but from what I've heard it might be one of those demons things". Tanjiro was almost out of breath at this but was glad he was able to answer the questions to the best of his abilities.

"Thank you so much Tanjiro! I'll never forget your help, and as a matter of fact'" at this Naruto pulled out a small bag from his thigh pouch, which he then gave to Tanjiro.

"There should be about 1000 ryō in that bag" with that he turned to where he assumed the center of the village would be. It wasn't much, a little bit less than what a D-rank would pay but the boy deserved some sort of reward for his kindness.

'1000 ryō! that's almost 6000 yen!, where'd he get all that money!?' Tanjiro practically screamed in his head.

Tanjiro was unsure on how he felt about the teen, carrying around a sword and talking about killing someone even if it was a demon as well as having currency that hasn't been in practice in over 40 years. Yeah Tanjiro was more than a little suspicious, though with how nice Naruto was he supposed he might have come from a wealthy family that ruled over some land long ago. But looking inside the bag he didn't think about it much, he could get his sister a nice new dress now!. As he was walking away Naruto thought to on the information he was given.

'hmm I hope that ryō is worth something here, it's made of gold so i'm sure even if its not a currency it has some value' He turned his head slightly back to see Tanjiro stare at the bag in amazement, and judging by his reaction it definitely was worth at least something.

Bringing his thoughts to the planet he was one, it didn't very too much from his world which he found quite odd, and as he picked up a map he noticed this world seemed to be more separated than his own, he wondered if the elemental nations would ever become the elemental continents, Kiri was already on its way as far as could remember. Another thing he found odd was the fact that his currency was somehow in circulation on this world at some point, very strange but he supposed their worlds were just similar in their retrospective histories. Looking up at the sky again it seemed to be around evening

'huh guess I just ended up walking for six hours' it was probably because Naruto never really took the time to think, after all he was fighting a war most of his life.

Making his way into what he assumed was an inn and handing the receptionist a bag of similar size as the one he gave Tanjiro, at which point they directed him to a room towards the end of hall, as he made his way into the room a thought ran through his head.

'Demons huh...can't be any tougher than the likes of the ten tails' he laughed a little, it was almost bitter for he new he had no chakra and at the moment no way back to his world.

He laid down on the available futon and decided once he got some sleep first thing tomorrow he was gonna find that Tanjiro kid again and see if he could help him just a little more.

"I wonder if Sasuke made it here, it was his plan after all" with those words filling the empty room Naruto decided a 12 hour nap in the nice warm futon would be his first objective.

End

Author's Notes

Alright well that's it for chapter one, I'm kinda writing this story in between being at work and home so it's taking me awhile to actually write it, especially when I forget my train of thought, however having said that I'm still gonna be writing when I can even if it takes me years to complete this, we'll see what happens.

YA BOII OUT.
