Dragon Slayer - Demon Slayer/Isekai OC

Summary:

Kira Barnes a twenty year old autistic girl who dies in her sleep from a sudden brain aneurysm and appears in the world of Demons Slayer confused and alone in the middle of the woods. Armed with only her phone and her wits..

What she doesn't realize is a godly being of reincarnation named Sable, crafted the perfect world for the girl containing trials. Should Kira defend herself from the demons and defeat Muzan Kibutsuji she would attain godhood over her realm and immortality.

Sable is not unkind however, and gives her an ability to defend herself he knows she would enjoy.. The powers from one of her favorite video games franchises, the Elder Scrolls. He gives Kira the powers of the Dragonborn and it's Thu'um.

(This story is apart of my 'Feline Afterlife' universe.)

Author's Note: All Japanese is through Google translate, blame them if anything is wrong. I will provide what they actually say in parentheses beside it ☺️ because I know how shitty it is to have to copy it into Google translate myself or go to the bottom of the page for translations.

This story will have smut! (At some point) I'm a coochie demon who can't help myself.

"Lilly.." I sigh loudly pinching the bridge of my nose. Do we have to do this every night??? Damn dog.. "It's midnightbed time. Not hole digging time! You're a granny! You need your rest!" I spout to my dog with a huff, walking inside to slide off my slippers. Putting on my outdoor shoes instead, I quickly return to my front porch and walk down the steps into the wildly overgrown backyard that's bordering the expansive Vermont mountains.

My 14 year old elderly Husky/Rottweiler mix stands next to the garage digging a hole into the ground while panting hard. I huff and pick up the chain inwardly grumbling incoherent slurs to my asleep grandfather who refuses to swap the thick metal chain out to something lighter. She's had this thick metal chain that's used on cows since she was a puppy. She used to be able to pull it no problem when she was younger, now she's having a harder time dragging it around. I have to go down and pull it for her up the steps so she doesn't strain herself.

"C'mon Granny!" I lift the metal portion for her, she looks up at me and practically smirks. Knowing she got her way, she walks up the steps leisurely while I tug the chain up for her. "You're lucky you're my child dog." I shake my head at her with a fond smile. Willing to do anything if it makes her more comfortable in her final months.

I open the door for her and unhook her, allowing her to waltz indoors with a smile. Huffing out I quickly step inside and lock the door behind me, tugging on it to make sure it's actually locked. I flip the switch next to the door, shutting off the outdoor light. My dog patiently waiting near the refrigerator for her payment for going to the bathroom.

"Fine! Fine.. damn cranky granny." I open the fridge and grab a mini Hershey's chocolate bar, breaking it in half. "Your payment my liege." I eat one half and give her the other with a bow and flourish, she crunches on it happily. You're spoilt now dog.. We give her anything she wants.. since she's on the last lap of her life. Her back legs are withering away and her mind is slowly going down the gutter. Often at night she becomes confused and experiences Sun Downing.. It's something that happens with humans that have dementia.. She's happy for now, but when she starts having issues.. we're gonna bring her to be put down. Not wanting her to suffer needlessly.

"Alright Lilly.. Go lay down and go to bed okay?" I rub her head with a soft smile, treasuring every day I have with her now..

I quickly wash my hands at the kitchen sink before I grab some Hershey bars from the fridge. Making my way towards my bedroom using my phones light to lead the way in the dark house.

I stop just outside my door and look to Lilly, doing my nightly routine... Just in case. "Goodnight Lilly, I love you. I'll see you in the morning." I smile at her before walking into my room, leaving my door open if she gets anxious and starts to sun down. She can come either to me or my grandfather to calm down. My elderly cat Lucifer follows after me, having been waiting for me to come back in. He's my little body guard and never leaves my side ever since I rescued him when he was a kitten.

Walking towards my bed, I sit down and dust my feet off. Grabbing the candy bars in my pocket, I crack one open and munch on them. Pulling up my favorite website I use to read fanfiction on my phone. I open up a reading list I made for stories I plan to read, and pick one that looks interesting about Demon Slayer.

-

I quickly finish the chocolate and toss the wrappers into my mini trashcan before laying down and reading until I can fall asleep. Praying that by reading the fanfiction I'll have good dreams based on the anime the stories are about. I've had good luck with it recently with a Black Butler dream where Sebastian was my personal butler.. and a dream where I got fucked by Aizawa from My Hero Academia, 10/10 best dream.

After about three hours of reading, I'm tired.. but not enough to sleep, so I exit the site I use and open up YouTube on my phone. Curse my night owl tendencies.. Grabbing my headphones from my nightstand I open up an ASMR video on my 'Nighty Night' playlist.

I sigh with content and lay back to get comfortable, allowing the soothing ocean waves to lull me off into dream land.

~ ??? ~

You have been assigned your newest charge.

Mother Tiamat's voice rings through my realm. "Hm? Another? And so soon?" A void black Jaguar with stars glittering its fur floats in his workshop as another soul is delivered to him. It's eyes glow fills the room with the light from stars going supernova as his pupils. Beautiful stars and constellations glittering on its pelt shimmer with life.

"It was not long ago that young Alexis concurred her trials.." The Jaguar sighs softly with a smile, looking over to the painting that holds her world. Lazing on my rock while I relax, wondering why Mama Mat decided to give me another soul to challenge. A soul shimmers to life in the globe in front of me. Humming softly I tap a claw on the globe and review the girls life.

"Kira Barnes.. Twenty years old.. Died in her sleep from a brain aneurysm... You are similar to young Alexis in many ways." The Jaguar sighs softly while staring down at the soul floating in his globe.

"Worry not child, for I am here now... I shall craft the perfect trial to see if you are fit for immortal life." Plucking the girls glowing blue soul from the globe he holds it in his paw before turning. Walking off of his rock he maneuvers over to his bookshelf, finding just the book he grabs it with his tail.

Setting the girls soul onto his worktable he grabs ahold of the book containing information on the world she yearns to be in and opens it. His eyes shimmering with a glow while he downloads it's contents. "Hm.. It seems.. My normal method of trial would not work with the world you yearn to be in.. You would be killed quite quickly and I would be robbed of my entertainment until I'm given a new soul..." The Jaguar squints in contemplation, not wanting to send a soul to their doom. He dislikes meddling with a trial once it starts, unlike his younger brother Kai who often protects his souls while they are tested.. he is the only one of our kind that has a high success rate with his trials.

"I suppose I require counsel..." The Jaguar shimmers before disappearing from his home.

-

Emerging in a workshop much like his own, but designed to be a pottery studio. He spots his brother who has taken the name Chester, working on his newest project. "Hm? Ah, brother Sable! I have not seen you in centuries!" The cheetah with its spots being black holes grins at his brother. Leaning back away from the pot housing his charge within it on the spinning wheel.

"Hello Brother Chester.. I require counsel on a soul I was given.." The Jaguar walks into the workshop and takes a look at the shelves holding the beautiful pottery showcasing the successful trials Chester has conducted. Each one housing the world crafted for the soul.. Truly beautiful craftsmanship.

"Oh? Don't you like to make them kids?" He turns away from his work, while wiping his paws clean of the clay looking at his brother. Wondering why he's having difficulty, he's been doing the same thing since he was created. Reverting all the souls he receives into child form

"Yes, that is my preferred method brother.. But the soul I was just assigned would die too quickly if I did that." Sable sighs softly.

"So? Another meal for your belly!" The cheetah rolls his eyes as his soft brother.

"I grow bored brother.. After such a great show with my last soul, I crave another! I need ideas. The girl wishes to enter a world filled with man eating demons she wishes to fornicate with." Sable shakes his head in exasperation. Why would a human want to fornicate with their predator? He does not understand..

"Make her a monster. That's what I like to do." Chester grins, showing off his razer sharp teeth. "I love the reactions they get when they realize they aren't human.. the despair is delicious." Chester licks his chops ay the memory of his last meal. "Try it Sable!"

"I.. I suppose I can try that.. But I will not force my soul to become the mother of monsters.. Like the last one who won your trials, poor girl.. Forcing a soul who has a fear of being pregnant to constantly be pregnant? You are evil brother.." Sable shakes his head at Chester with a scowl.

"It was hilarious!" Chester cackles and kicks his feet in the air. "If you want evil.. You should see Tim's work." Chester says with a glint in his eye. "He is a master manipulator.. Only two successful souls since the dawn of existence?? Genius!"

"Yes.. I dislike Tim.. I know that Mama Mat steals the souls we use from the dogs.. but I believe we should still be honorable Sheppard's! And give our souls a fighting chance for eternal peace... I must go now.. It was good seeing you Chester." I bow my head to my brother.

"Mpmh. Good seeing you Sable. Tell Kai I said hello if you see him again!" Chester waves to his brother before turning back to his work, sculpting the perfect world for his newest soul.

-

I shimmer back into my workshop and sigh, floating over to my bookshelf that holds all the information about anything the soul has interests in. I search along the shelves for the correct novel, having seen her great interest for the subject when I overviewed her life. "Ah! Here we are.. You have a great interest in this world as well.. lets hope this gives me some inspiration" Plucking the book off the shelf, my eyes glow for a moment while I absorb the information. "Perfect! This is the perfect thing! You remain human in visage but are a dragon as well! I shall make you a Dragon born! Dovahkiin!!" Sable smiles with excitement flying over to his workbench to get to work crafting the girls world.

"Good luck Kira Barnes! I wish you enjoy finding out what you were gifted!" Sable smiles at the painting that hangs on his wall, watching it with intrigue as the girl begins to wake.

- Kira POV - ??? -

Feeling a gust of cold air, I shiver and reach down for my blanket thinking I kicked it off in the middle of the night. Feeling around blindly I touch the familiar sensation of grass and yank my hand back in alarm. Opening my eyes I wheeze in alarm, my eyes bunging out of my head in shock. "WHAT IN TARNATION?!!?" I scream out in shock and fear scaring the nearby birds from their trees, seeing a dense forest around me. Did I sleep walk?? But- I look down to my feet and see that they are perfectly clean. Even the clothes I'm wearing are tidy.. So that means I was taken here?? Grabbing my headphones that are still in my ears, I pull them out with urgency.

"None of these trees species are native to Vermont! What in the fuck!! Have I been kidnapped for some rich person hunger games bullshit?!?!!?" I screech while holding onto my knees, my pudgy belly getting in the way. I follow the wire of my headphones and realize that I have my phone next to me on the ground. PRAISE THE SUN! I scream mentally before picking it up and kissing my phone dramatically.

Pressing dial and 911, I hold the phone up to my ear. 'The number you have reached is out of serviceHUH??!!?? IT'S 911?!!??! HOW COULD IT BE OUT OF FUCKING SERVICE!!?!!

"That is not very cash money of you phone!! You little bitch!" I growl at the device with a scowl on my face. Sighing loudly I look around in confusion, trying to look for any indicator of which direction my kidnappers came from. Seeing absolutely no trace of a trampled down pathway or any drag marks.. Hell there's no tire tracks! it was as if I was dropped from the sky, or I spawned in like Steve from Minecraft. I get up off the ground with a huff. God dammit! I'm too dummy thick for this shit!

"Well.. When in doubt.." Spinning around on my feet for a second with my eyes closed. I point in a random direction and open my eyes. "ONWARD!!" I proceed to begin my determined march, holding up my phone I start up my playlist... Starting off with 'We're off to see the wizard' which makes me laugh at the irony.

- Several Hours Later -  Evening -

"Mayday mayday, the ship is slowly sinking~ They think I'm crazy, but they don't know the feeling~" I sing along to the song blasting from my phone, crouching down to the river I grimace. Trying to keep my spirits up and animals at bay by singing. Don't think about all the bacteria and little parasites! Just do it! You have been thirsty for hours! We'll go to the hospital once we find out where we are! It will be fine! Steeling my nerves I take a shaky deep breath and shove my hand into the water. Taking some good gulps to satisfy my thirst. Hey, ain't that bad.. Tastes like Poland Spring!

"They're all around me, circling like vultures.. They want to break me, and wash away my colors..." I take a deep breath and stand back up while holding up my phone to use it's flashlight, searching for a decent place to sleep. The moon hidden from the sky.

"WASH AWAY MY COLORS!!! TAKE ME HIGH AND ILL SINGOH YOU MAKE EVERYTHING, OKAY! OKAY! OKAY!! WE ARE ONE AND THE SAME, OH YOU TAKE ALL OF THE PAINAWAY! AWAY! AWAY!! SAVE ME, IF I BECOME!!!! MY DEMONS!!" (Starset, My Demons). I scream out at the top of my lungs, hoping someone hears me. I exhale and let the song continue to play, walking along in the dark. Completely exhausted, having been an otaku for most of my after high school life.. and I've never really been athletic at all due to my asthma. Nearly tripping on some branches and rocks on the ground.

"Everything is fine... It's fine Kira. We're not gonna die out here, we're gonna get help!" I talk to myself to calm myself down from the creeping panic, constantly checking for any signs of service.. oddly enough my phone's battery hasn't gone down since I've been out here which is odd. My phone has always sucked at its battery like it was saving dick by giving it CPR.

"At this rate.. I'm gonna have to sleep.. on the bug infested ground." I shiver with disgust of the thought of those little creatures crawling all over me. "Nope- can't do it! I'll stay up. Fuck that. Nope!" I shake my head vehemently, not wanting the bugs to touch me unless it's on my terms. I don't mind bugs at all! As long as they don't touch me, we are Gucci!

I continue to walk through the dark woods, singing loudly I find a rather large tree that appears to be hollow. Huh.. pretty purple flower petals. I think to myself wondering what species it is with a hum. Looks familiar.. I'll probably figure it out later. Grabbing a stick off the ground I sigh and use it to whack away any possible spider webs that are inside the hollow hole. Not wanting the sticky webs to get onto my skin.

Crawling inside I scooch around and get myself comfortable. Taking long deep breaths I grab my phone and plug in my headphones. Playing some calming ASMR to distract my brain from the bugs. Looks like I'll need to survive.. There's been no sign of people so far.. fuck.

- Next Morning -

Standing on the bank of a beautiful mountain stream that the tree was located nearby.. it's more a babbling brook then a river. Humming in thought I toss some rocks away, looking for a decently sharp one. Several other large stones are being held in my shirt like a kangaroo pouch. Planning on using them for a fire pit.

"Eh.. this one's good enough." Grabbing the sharp stone that has a bunch of pretty colors that kind of looks like metal, I stand back up and crack my back with a grunt. Oof- Jesus, I'm not even 30 yet and my back is fucked.

I huff and walk back towards the purple tree that I'm calling home for right now. "Okay.. I saw some pine trees nearby as well, I'll use the rock to chip away some of the resin.. I'm gonna have to make a fire too for warmth and charcoal for the glue." I talk to myself, grabbing a pretty long stick off the ground. I bend it and feel it's structural integrity and nod to myself in satisfaction. "Not rotten, that's a good sign. It's sturdy too. This will do for a spear if need be. Who fucking knows what's in these woods." For all I know I could be in South America.

Sighing I crouch down to just below my tree, grabbing some rocks I collected earlier. Making sure I'm a good ways away but still close enough for warmth to travel. I position the rocks in a large circular pattern. Placing a good bit of sticks I found on the ground in the center of the rocks, I grab some dry leaves and begin the tedious process of making fire..

Spinning the stick against the piece of wood, I grunt in effort. Becoming increasingly tired, I kept going until a small ember is formed. I deposit it onto the dry leaves and hold it up to my face. Gently blowing against the coal, nurturing the growing flame until it is steady. C'mon Calcifer, grow!

Placing the lighted leaves into the pile of more tinder underneath the logs. I continue to blow it gently until it's a roaring campfire. "THE RING OF FIRE!!!" I hold my hands up with victory. "Hah hoo hah hee hah hoh hoh hoh-" I say the lines from Finding Nemo with a snort while I add on more tinder to keep the fire going. "One task down.. good thing I found a good bowl shaped rock to hold the resin!" I smile at myself as I look down at the rock, a pile of pine resin chunks sitting on a large leaf nearby.

Grabbing the long branch I intend to use for a spear, I begin to create the void where the shiny rock will sit. Waiting patiently while the fire burns down to create some coal for the glue, my stomach rumbling loudly. "We've gone longer without food in the past, shut yo bitch ass up." I growl in anger at my stomach, giving it a glare.

- Couple Hours Later -

Having mixed the melted pine resin with a chunk of charcoal I smashed up into a powder, I applied it liberally to the spearhead with a stick. Ripping off the sleeves of my shirt, I wrap the torn fabric around the crafted spear over the molten hot pine glue. Making sure that it's tight and it won't give way I nod in satisfaction. "Thank fuck my Papa taught me how to survive in an apocalypse situation. That paranoid old man was good for something after all." I snort out a laugh remembering the weekends me and my grandfather would go into the woods with only some food so he could teach me how to survive.

Standing up from my cold fire, I hold onto my spear tightly in my hands. Thank fuck he taught me how to fight with bows and arrows as well as spears and knives! "Time to hunt." I turn and walk towards the brook, breaking branches in specific ways to indicate my pathway like my Papa taught me.

- ??? later -

Having followed the brook down stream. "Hah! Let's go!" I cheer with an excited grin, staring at the pond in front of me teeming with fish! Most of which I don't really recognize.. But I saw some that look somewhat familiar..

Grabbing ahold of my spear, I walk along the edge slowly. Looking for any fish swimming in the shallows that would be good prey, my eyes lock onto the swimming fish. Looks like a carp from animal crossing.. Heaving up my spear over my shoulder, I prepare to throw it. Using my other hand to aim, I take a deep breath and on the exhale I throw it full power.

The spear stabs into the fish clean through, flailing around violently I grab it quickly before it could get away and hold it out of the water. "I.. I did it?... I DID IT! LET'S FUCKING GOOOO!!!!" I cheer out while jumping up and down, a beaming grin on my face.

Crouching down on the bank I slice into the fishes head and kill it quickly with my spear using the blood to lure in others. I gouge out its eyeball and hold it under the waters surface with my bare hand, jiggling it every so often. A look of concentration on my face. Knowing the fish would have felt the splashing of it fighting back and have swam away. The blood and it's eye will trick them into thinking it's a free meal.

After a few minutes a curious fish swims up and swims quickly towards me. Biting onto my finger and the severed eye, I grab ahold of it by it's mouth and pull it out of the water. I smile with my success, deciding two is enough for now. I quickly kill the second fish so it doesn't suffer needlessly before getting up and walking back the way I came. Fish held in one hand and my spear in the other.

- Evening -

Roasting the fish over the fire pit with an excited smile. I use another sharp rock I found on the way and follow the tiktok I downloaded a while ago that I planned on trying by myself. Spinning the inner bark off of the branch I fold it precisely and grab the pine resin I made and use a stick to apply it to my new water bottle I just made. Using a chunk of branch as a stopper and some of my sleeping pants to keep it together. I also pour some resin inside the bottle to make it waterproof so the bark doesn't rot from the inside out.

While the glue cools I grab the sticks holding the fish over the flames and take a look at them. "Seems cooked enough.." I pull them off the hot fire and let them cool before I dig in like a wild animal. Saving a couple chunks of meat to use as bait until I can make a trap for little fish.

The hairs on the back of my neck stand straight up. The fuck..? I'm.. I'm being watched? No- hunted.

I bite into my fish while leaning back and grabbing my spear with my other hand. Just as my hand wraps around it something leaps from the bushes.

Jumping away from the fire pit I hold my spear up and my eyes widen at what I see. "Kuso ningen! Naze saketa nodesu ka?! Watashi ga anata o taberu tame ni naze anata wa shinanai nodesu ka? (Damn human! Why did you dodge!! Why can't you just die so I can eat you!!)"

"Japanese??? I'm in Japan?" My eyes wide and I take a look at the man.. er thing that's trying to attack me. What the fuck is that thing? It looks familiar..

"Korosukara Fujinoki kara hanarero! Watashi wa onaka ga suite imasu! (Get away from the wisteria tree so i can kill you! i'm starving!)" The creature goes to step forward but hisses at the tree, taking a couple steps back but keeping an eye on me.

I back up to my tree home and see that the creature doesn't come closer. Wait.. Holy shit!!!! "Holy fuck you're a demon!" My eyes widen in alarm. I'm in demon slayer?!! "Fuck! Of all the worlds!- Back up! I'm not afraid to kick your ass!" I know I won't be able to kill it, but I could hold out till daylight. Holding my spear up I growl at the demon threateningly, adjusting my grip on the spear.

"Anata wa nanite koto o itte iru nda? Tabete agerukara koi yo! (What the hell are you saying? Come here so I can eat you!)" the demon roars out, swiping it's claws at me.

"Hmh.. so you're probably a newborn. You don't have a blood demon art yet or else I would be dead already... Hopefully the hee hee man isn't in the area." I sigh and grab my fish and sit down inside the tree, knowing I'm safe from this lesser demon inside of it. I bite into the meat and eat while watching the demon froth at the mouth trying to get to me. Fuck sakes.. surviving just got harder.
