DISCONTINUED What would become of Water Hashira Giyu Tomioka had he become demon? If he had come just half a day earlier? Well, that we'll never know. But, what about later on? What should happen if he fell into the hands of darkness, sinking into the depths of evil? Could he possibly be brought back? Or perhaps he'll give in to bloodlust, and a solution be found far too late. Would Giyu Tomioka feast on human blood before a cure could reach him, or will a strange feeling only experienced once before prevent the horrid fate of slaughter? ••• First chapter or so may kinda suck, I'm bad at beginnings ->- latter chapters should be better! 2024: Y'all got this to #1 in giyuxtanjiro how the hell- ••• AU NOTES: 1. An AU where Tomioka Giyuu has been turned into a demon, and Tanjiro seeks out a way to cure him. Along the way, Giyuu seems to give off new emotions and grows closer to Tanjiro, possibly revealing something to the demon slayer as time goes on. 2. Everyone has been aged up to around four years for legal reasons. Those ages can be seen as follows: Tanjiro - 19 | Giyu - 25 | Zenitsu - 20 | Nezuko - 18 | Inosuke - 19 | Muichiro - 18 | Kanao - 20 | Genya - 20 | Aoi - 20(?) | Uzui - 27 | Rengoku - 24 | Mitsuri - 23 | Obanai - 25 | Sanemi - 25 | Gyomei - 31 | Shinobu - 22 3. Nezuko has already been cured and all of the pillars are alive. This won't match up with the manga, though I can't guarantee that I won't make some references to it.

READ THE A/N BEFORE READING THE STORY, PLEASE AND THANK YOU!!! At the age of 14 Tanjiro and Nezuko were turned into demon's after their family was slaughtered, but when muzan(Michael Jackson) was injecting them with his blood he realized they were different... they could take in almost double the amount of blood as the blood given to the upper moons. He decided that instead of letting them stay and get caught to take them in as his own, in doing so he replacing their memories of being human into memories of being his children. Two years of being upper moons 0(they share the title as the demon pair, they always work together), Tanjiro and Nezuko find and kidnap some people, but what happens to them next?

What if when the breath of the sun user spares Muzan's life he got extremely depressed, because he failed his life mission, and decided to get drunk? What if he encountered Muzan again and impregnated Muzan? What if Tanjiro and Nezuko were the aftermath of that night of heavenly bliss? Tanjiro and Nezuko had lived for many years being born demons, however, they were immune to the sun so they acted as their mothers spies. Their mother ,Muzan himself, refused to kill his birth children due to his motherly hormones even if they had achieved something he longs for. To fit in they pretended to be coal burners till one day they had to drop the act when our little lonesome Giyuu came to town.

this is a demon Tanjiro Kamado x Tomioka giyuu. Inspired by A_wild_GOOSE. "Tanjiro and his sister, nezuko, have a special connection to muzan, it seems. Having no memories of his past human life, Tanjiro woke up as a demon. Muzan had apparently experimented on him- gave him more blood than muzan had ever given anybody. He did the same to his sister. Because of this, they had a blood bond stronger than anybody else's, like a mother and child. Tanjiro and his sister went out to hunt one day and unluckily encountered Giyuu Tomioka, Shinobu kochou, and sanemi shinazugawa..." disclaimer: I do not own any of the characters, nor do I own the kimetsu no yaiba anime or manga. the only thing that I own is the storyline and plot! you are free to make stories or really anything based on this fanfic, as long as you give some credit to meh :) ONGOING ❌ ON HIATUS/BREAK ❌ COMPLETED ✅ DISCONTINUED ❌

Cover created and drawn by me 💞 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The fight against Demons had gone on for as long as anyone could remember. There was never an end in sight. The Demon Slayers continued each day working to chip the number in hopes to rid the world of the biggest threat; Muzan. Nothing ever changed in their lives. At least, not until the day a new threat made their presence clear. A demon far more dangerous then Muzan himself! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This story is a Demon Tanjiro, who is an Uppermoon. The cover is what he looks like! (I love a motherlike Demon Tanjiro!) 💕

"I swear... I will turn you back into a human. Just wait, Onii-chan." * * * What if Tanjiro returned home early that night, before the Kamado Family was attacked? A turn of events would lead Kamado Nezuko to survive the night while remaining a human... whilst Tanjiro would be the one turned into a man-eating demon. --When the older brother had far higher adaptability to demon blood than his younger sister. --When the younger sister was far more talented as a Demon Slayer than her older brother. This story follows a Demon Slayer named Kamado Nezuko... and her difficult journey that she walks together with her comrades. In order to defeat her family's murderer... in order to return her brother to a human. ***** This is an 'what if' role swap story of Kimetsu no Yaiba. Demon Slayer Nezuko becomes much stronger than Tanjiro with her talent. Demon Tanjiro will also be stronger as a demon than Nezuko was in the original story. The story is rather dark and lore-based, but I'll be integrating romance elements here and there as well. ...please be aware of the word count, I write a lot as I try to be accurate to original plot as possible. Please enjoy. *** Kimetsu no Yaiba belongs to Author Gotoge Koyoharu, and Publisher Shueisha. Only some OCs belong to myself.

------------------------------------ This is a role swap AU where Tanjiro become a demon and Nezuko becomes a demon slayer. Tanjiro is still the oldest sibling among the Kamado's.

This is the story about how Tanjiro and his siblings survived and no one became a demon. But they still need saving and to be protected, not by from a what, but to be protected from a who. Tanjiro meets Muzan in the town and the things he does and say convinces Muzan to take a different approach to the Kamado family.
