Hunter has had enough of Emperor Belos' abuse.

Your entire life has been spent in a experiment facility. Your quirk is strange and powerful, and no one can quite pin point what it is, which is why you are relentlessly experimented on. That was the life you knew, and your entire world was inside that facility. You've never seen trees, you've never seen a fork, you've never seen anyone wear something other than a lab coat. You were anything but a normal child. Far from it in fact. One day, you're saved. But it takes you a long time, a lot of help from the loving class of 1-A and a tired man with black hair to be a normal child again. ||Highest Rankings|| 3 in #mha [7/4/19] 2 in #Hero [8/4/19] 1 in #aizawa [7/4/19] 6 in #bnha [7/4/19] 8 in #xreader

Moshi moshi~! This is a Male Various x reader story! The love interests will be males only, and I will be using her/she pronouns. There will be many love interests but each will have their own ending! Plz read, and I will not be doing lemons, sorry!

♧ (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!

this takes place in the modern era, (after the ending)

He was known to be reserved. And she was known to be the newest Upper Moon to ever exist in the era. Yet, she was so similar to him. He watched her often getting called upon by their Master. He watched her smile at something that he couldn't understand. That's when he realized, she had retained her human emotions. Unlike him, driven by a certain hatred within his demon soul. Yet, on the night he went out hunting together with her, watching the way she glowed beneath the moonlight. He felt a burning sensation within his cold heart, a feeling he found familiar but was long forgotten once. Was it love? He thought. Soon it turned into a competition, a constant need to see her every day. Getting irritated whenever the other Upper Moons were near her. He was known to be reserved, but oh well, he was known to be hot-headed when it comes to her.

A voice says,calling me. Ugh what the fuck I'm sleeping go away,its probably mom. "...Y/n.." Wait what the fuck I live alone YEEETT!!!
