In this story is a different way that KNY could of ended, which includes made up characters that are children of some of the hashiras and demons. Most of the kids are completely made up. This story will mainly revolve around the kids instead of the adults. Which includes Misturi and Obani's kids, Tengen's kids, ect. This story starts years after the final battle, but instead most of the people the died survived since the master and Muzan came to a conclusion meaning that most of the upper moons and lower moons including Muzan will drink something that will prevent them from eating or hurting humans.
BTW in this story they live in the states but the kids of the characters still attend Kimetsu Academy.
another thing is that this story was made by my cousin, sister, and I 2 years ago.

(WARNING: This story will be sfw, but there will be some blood, implied death, fighting, some gore mentioned, and a few other things that will be made aware by warnings. Pay attention to warnings at the top of any chapters please.) Once in the mountain villages it was a custom that once a year on the night of the new year's first moon, an unlucky young lady would be selected and left for the demons to become one of the unlucky few who married such a husband. In exchange for this offering the demons would protect the villages and leave the humans in peace. Until one day a powerful warrior drove the demons away freeing the humans of them. Now 2,000 years later, it's become a tradition that once a year, a new young lady would be picked and wait for her future husband to retrieve her from a shrine in the mountains. And now the lucky tradition would fall upon Y/n L/n. It would be her own turn to take on the tradition and not have to worry about demons. After all that part of the old tradition was just fake, made up by paranoid ancestors. Everyone knew demons didn't exist. ...Right?Complete
○°•The Moonlight•°○ ♡Demon Slayer x Demon F! Reader♡
♧ (Y/N) is a nice gentle demon, but can be quite sensitive at times. (Y/N) became a demon by almost being killed from Muzan Kibitsuji when he was killing your family on a cold windy night. His blood managed to infect her wounds to make her turn into a demon. He didn't notice because he left. Though she actually didn't know, she was a special type of demon. (Y/N) ran away from her house then found a small abandoned cottage wooden house that was still in very good condition, so she now lives there. She goes outside on nights in front of her new house to admire the moon's beautiful moonlight from the balcony she has. "I wonder why someone would abandon a beautiful wooden cottage with such scenery like this?" Her eyes sparkled as the moon shined in her eyes. ♧ Slight Various Kny x Reader! ◇ (Y/N)= Your name ◇ (L/N)= Last name ◇ Maybe grammatical errors.

All demons are grey in the dark
"All cats are grey in the dark." This is a proverb. It means that in the dark, you can't tell one cat from another. In a figurative sense, it could also mean that someone who has too little information can't properly assess the situation. They can't distinguish between good and evil. When the Demon King died, the black line separating good and evil was broken. Demons find themselves, demons seek themselves. Demons are evil, demons are good. Demons remain lonely, demons find the family they didn't know they were searching. But how can you tell them apart if you can't see in the darkness? How can you judge whether you're doing the right thing when all you can see is grey? And in the deepest darkness of ignorance, confusion, the darkness of a decline of selfishness and ignorance, only the cats seem to see through the darkness. This story is a tragedy, just like Demon Slayer. There is an ending. Is it a good one? A bad one? Is the dried cat blood on the ground worth it? Was it all worth it, were the dead, the lost, worth it, just so someone switches the light button on? Was it all worth it when you look around and realize that cat blood is just as crimson as a human's? ...Basically: "What if the hashira didn't fall into the infinity castle?"

I probably accidentally used she/her pronouns in this for Y/N.... Sorry if i do/did «» "are they the children to Master Muzan?" A demon asks another demon, who shrugs in response ---- Y/N who was hated in their home village when they were a human. They were considered a freak after one of their eyes became (f/c) for a few seconds. No one knows why Y/N's eye became a different color. Y/N then became a demon, and Muzan took Y/N in and their sisters as his own children. Why? No one knows Something about Y/N was different. ~•~ I OWN NOTHING OF DEMON SLAYERS ACCEPT MY OCS!

An Endless Cycle (Muichiro X Reader)
So basically, you. Muzan's 14-year-old half-demon daughter (I know it's cliche but bear with me) who he doesn't know even exists, somehow ended up under the suspicion of being a demon, which you were, halfway. And it was decided that you would now be living with the famous insect hashira. Shinobu Kocho. In the Butterfly mansion until they found out whether you were a demon or not after the test they had prepared had failed. And though they would never admit it, they were basically holding you hostage and waiting by to kill you off. You refused quite a bit but you apparently had no say in it. Well, you might've not liked the fact that they were currently holding you hostage to figure out whether you were actually a demon or not before killing you after figuring out that you were a demon like Sanemi so wished to do so. There wasn't, much you could do in this situation. The most efficient solution you could think of to get them to leave you alone for the rest of eternity without spilling any blood was to lay low until their suspicion of you being a demon eventually died down and they allowed you to leave yourself. However... It seemed there were quite a number of Demon slayers who greatly disapproved of your stay here, or at least they were very wary of you. the most annoying one being Sanemi Shinazugawa. The reason was obvious enough. You were a demon. Which now made the biggest hassle you had to deal with, staying alive until that point. You have met quite a few demon slayers during your stay at the butterfly mansion, and though not many had been very pleasant. There were others you encounters with a few individuals who were... Strange, yet enchanting. The most interesting one yet, a minty-haired airhead. Trigger warnings: X Swearing X Gore X Violence X Grammer Mistakes X Death

Muzan cares about himself and only my himself. No matter how strong some demons are, he never really cared about any of them. He only needed them to find the blue spider lily and kill Tanjiro. Except one demon made a exception. The demon killed the boy with hanafuda earrings. . Muzan never expected to be this demon. But he knew the demon had a crush him so.. Why not like him back as a reward? After all Muzan did like him a little bit... I have seen barely Enzan books. The ones I find are complete or discounted. I'm making this book as long as I can and complete like that. I am a huge multi-shipper.
