so tanjiro kills himself as a demon which makes everyone's heart go into depression and when they all reincarnate in the future everyone except tanjiro has their memories and goes protective yandere over tanjiro and will protect him from everything including himself (btw everyone was alive during the fight with muzan)

What if Tanjiro had a natural demon slayer mark he was born with? What if that mark didn't give him incredible strength, speed, or agility, but did something else? What if Yorrichi hid his blade in a cave on the highest peak of the Kamado family's mountain? What if Tanjiro learned the Hinokami Kagura from a young age? Those are questions we don't know the answer to. The timeline is a strange thing. Just one change could alter the fate of humanity. So what would happen if all those questions came to fruition?

Rui had everything in a family , a mother , a father , even siblings. But Rui wanted one more thing and after thinking about the one last thing he needed. He finally realized he needed a lover , so when Tanjirou came into the mountain Rui thought he was perfect to be his lover.

Tanjiro kamado does not exist instead it is sumiko kamado. sumiko is just like Tanjiro, she is the eldest child has little sibling smiles brighter than the sun itself, she sells charcoal but that is all going to change on a certain night. nezuko kamado does not exist instead it is nezo kamado he is the eldest son. both he and his sister were known in the village for their looks. in the corps sumiko is known for her beauty and talent as she doesn't have enough physical strength like Tanjiro, she instead is extremely fast and very flexible which helps her in strength her brother is known to be cold hearted to every boy that talks to his sister while only being kind to his sister and respecting women.

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.

Tanjiro gets turned into a demon instead of Nezuko. Started: 28/9/19 Ended: Never?

When Yoriichi died, he died crying for his older brother who turned into a demon. He cried because he couldn't accomplish anything he was supposed to in his life. And then, Tsugikuni Yoriichi was reborn as Tanjiro Kamado, an omega prime. And apparently, he was cute enough to get the attention of all the Hashiras in Demon Slaying Corps. And not only them... Kibutsuji Muzan claimed him even more beautiful than when he was still beta Tsugikuni Yoriichi. Well... Yoriichi - now Tanjiro - didn't think so... ° ° ° ° ° ° ° ° This is an reincarnation AU where beta Yoriichi got reincarnated as omega prime Tanjiro. Also... Everyone seems to miraculously fall in love with him... Alpha/Beta/Omega Dynamics

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.

Tanjiro's family was brutally murdered by Muzan Kibutsuji. Tanjiro himself, was peacefully sleeping in the house when the door was broken down and his family dead. Muzan walked to him, and told him, 'Follow me, I'll give you a better home.' and Tanjiro did. He became Muzan's most loyal servant, soon Muzan felt the urge to protect and care for both Tanjiro and his sister, Nezuko. ! I don't own the characters in this story, neither do I own the art ! ! Boy x Boy ! ! Demon! Tanjiro ! ! Parental! Muzan ! ! My writing sucks, like that desc. Oh well, enjoy !

A man named Giyuu Tomioka had just finished a mission till he saw a burgundy coloured cat following him
