before anything I am LIFE_SUCKS_RN. It's just that I had to make a new account so w/0 further a due.
First story so please no hate but anyway. What if Muzan had the idea to make the perfect demon, not one that could walk in the sun although he would like that, and might happen. He wants a demon that he could be able to mold and shape and put his beliefs in. So he had a wonderful idea to take a child and raise them as his own and twist the world. Will his idea work or will it fail? read on to find out. And I apologize in advance for any spelling mistakes in the story. Also I abandoned my original idea of the story after chapter 20. The rest of the story makes since but has some holes. I am planning on rewriting the chapters to make it flow more smoothly.
⚠️Warning ⚠️: I do NOT own demon slayer or any of the characters all rights go to Koyoharu Gotouge!! Also this isn't a Muzan x Tanjiro story!!

The Child of Darkness (Demon Slayer Role-Swap AU x OC)
What if the Kamado Family adopted a child the same age as Tanjiro and Nezuko, the twin eldest siblings of the house? What if Tanjiro returned home earlier instead of staying at Saburo-san's? What if Nezuko left the household to deliver some kimonos and stayed at Saburo-san's? What if Tanjiro's new adopted brother became a demon trying to protect his new family from Muzan Kibutsuji? Everyone is dead. Except for Nezuko. Except for Tanjiro. Except for Tocho. The triplets must survive together, using their combined heightened senses to survive in this cruel, cruel world. At least, that's what they thought. Until Tanjiro turned into a demon and lost his wits. What will they do when Giyu Tomioka arrives, threatening to kill not only Tanjiro, but Tocho as well? How does Tocho keep his wits but Tanjiro doesn't? Only the Author knows the answer to these questions. Click on the 'Read' button to find out more. Disclaimer: I am not Koyoharu Gotouge, I do not own Demon Slayer, I only own Tocho, and the altered versions of the original plot, not even the concept of Nezuko's heightened sense or Tanjiro's demon nature is mine, I first got the ideas from Novirp13 on Fanfiction.net, so you can check out their story too. All images belong to their respective creators, since I can't draw to save my life, the only thing I'm good at is making collages. Note: I'm following on from the Anime. Not the Manga. The Anime. Keep that in mind as you read. Because honestly, I can't be bothered correcting people when they tell me something's wrong. It's a fanfiction, for god's sake! Stuff gets changed anyways, so why care? Also, I'm toying around with the ages a bit and altering Nezuko's appearance. Nezuko and Tanjiro will be the same age, but Nezuko being born a few minutes later than Tanjiro, Nezuko will also have red eyes and red hair. Tocho has the same birthday as them, too, so they can really be called triplets.Complete

Cursed {Demon Tanjiro AU}
I was so useless, I couldn't do anything, except quake before this man, no devil, in fear. Hello, this fan fiction is going to be where Tanjiro becomes a demon, instead of Nezuko. Before reading this I am going to tell you that this fan fiction will take a totally different path than the anime/manga does. This fan fiction is all purely based on the events in the anime, till chapter twenty, and then afterwards events that are not in the anime, only in manga, will be taking place. ~ Cover Art: @ForeverFireAnime ~Disclaimer: Demon Slayer: Kimetsu No Yaiba does not belong to me, it rightfully belongs to the amazing person, Koyoharu Gotōge. She did such an amazing job, this anime/manga is a masterpiece. So give her all the amazing credit please!!Complete
Our Bond Can't be Severed by Anyone!
It was unfortunate when Tanjiro twisted his ankle but Nezuko was all too willing to take the charcoal to town in his place. She returns home to a blood-covered scene that makes no sense. She reunites with her brother who is no longer human and shares only a few words before disappearing: "Hide... he'll find you!" Nezuko, wearing her beloved brother's hanafuda earrings, vows to become a demon slayer and find her brother and save him from the monster known as Muzan. How will the course of events change? WARNING. This. Is. Dark. Includes blood, gore (this is demon slayer y'all), force-feeding near the end, angst, lots and lots of angst, mental manipulation, Muzan Kibutsuji is a motherfreakin warning okay! Also, language. Warning: I am FIXING things. People are going to survive. Kyojuro is going to see his little brother again! Sanemi WILL hug his little brother. Kanao will NOT lose her other sister! I FORBID IT! Disclaimer - I own nothing! Not the characters or the art. I mean... like the plot is kind of mine but even that! This is just an AU that I came up with. I don't own the characters, that credit goes to Koyoharu Gotouge!Complete
