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

♧ (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. I keep switching pov, using ",but" "well" "Then" and it's just a mess ◇ I'm typing this on my school's computer then copying and pasting into my phone so the lines might not be good. ◇ I'm going to edit a lot of stuff. . . ◇ I'm a newbie writer so please don't be mean to me if it's bad because it probably is. ◇ I try to get at least 1000+ words for each chapter. ◇ I'm not the type of person to cuss very likely, so I use something like "chicken nuggets" for the cussing. Sorry if it annoys you. ♤ The pictures and gifs don't belong to me. They belong to the owners of them. Unless I say it is. ♤ The characters belong to Koyoharu Gotōge the writer and illustrator of Demon slayer. ☆ of course there will be gore, fighting, maybe even abuse, ect. ☆ This does contains spoilers for the anime episodes and manga spoilers. ☆ A notice and reminder this is a "peach pink theme female demon", so the color of the kimono and overall theme color for the female demon is peach pink theme. ♡ Now we will begin this Demon slayer x Demon F!

Y/N is an old-money European, that is until her parents decided to send her to a school in the United States in order for her to get a grasp of how life is without the luxury of Europe. In this story Y/N is a new student at Kimetsu Academy public school, what new challenges will she face? ♤♧♡♢ Hello everyone! This is my second fic but the first one is currently unfinished, so this one might not be the best considering that I started this in 8th grade and have not been on Wattpad for a long time. I'm an American upper middle class man so European or rich kid habits might not be totally accurate but I've done some research. A reoccurring thing that happens in most of my books is the overuse of the number four, see I have OCD and four is kind of my lucky number so if there is a quantity it will most likely be because of me not because of a hidden meaning behind the story or anything. I currently have Tiktok but I'm logged out. If anyone wants to be mutuals just message me, I'm always down to make new friends. 🗣️Y/N is upper class european so imagine her with a really snobby accent🗣️ ♤♧♡♢ Characters used: Tanjiro Nezuko Inosukee Zenitsu Kanao Aoi Genya Muichiro Yuichiro Shinobu Uzui Mitsuri Kyojuro Obanai Giyuu Kanae Sanemi Gyomei Yoriichi Murata Sabito Makomo Suma Makio Hinatsuru Hotaru Kanamori Kaigaku Ume (Daki) Gyutaro Nakime Hakuji (Akaza) Douma Michikatsu (Kokoshibo) Muzan Lady Tamayo Yushiro

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!!
