♧ (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!
