(Kyojuro Rengoku x OC demon slayer) READ DES! by Kyojuro69Kun

"Her heart was overgrown over time, with the hatred she had for herself." An above-averagely tall woman, long brown hair and emerald green eyes, had just become a Hashira and joined one of the strongest members of the Demon Slayer Corps. But she meets a very fiery and passionate man, who secretly was head over heels for her, but doesn't show it. This fanfiction contains the story of their love unwinding before your eyes, as they spend time with each other, slowly falling in love. Runaka's confident, strong, bold and kind personality made Kyojuro fall hard for her. And Runaka seemed to be attracted to Kyojuro's bright and passionate personality. Though, she finds him adorable more than she finds him attractive. His immature demeanor around her is just what she wanted. (This is my first fanfiction! Pls dont judge me if theres anything wrong. Idk if I would be able to make a proper cover page. Also the Breathing Style is created by ✨me ✨ but pls enjoy.) ✨bye✨ <3 I don't own any characters in the book. All the characters belong to the creator of Demon Slayer, Koyoharu Goutouge. The only characters that I own are my OC's family.(Ayaka, Mikoto, Akita, Amare, Kinoko) There might be other characters, but I ain't revealing 'em! READER DISCRETION IS ADVISED!

If you wanna understand this more, please read the first one "Priceless Smile". May you all enjoy reading! I apologize again in advance for the misspelled words and wrong grammars. ¤The original Kimetsu no Yaiba/ Demon Slayer, its plot, and its characters belong to its rightful owner Koyoharu Gotouge. Only my original characters and some of the plot which is not a part of the original work belongs to me. - this may have very slow updates unlike the first one, I'm sorry!

Asami Kaneko was saved by the Love Hashira, Mitsuri Kanroji, when a demon attacked her home and, much like many people in this demon ridden world, her parents and younger brother were killed. Upon seeing the young six year old, Kanroji decided to take in the girl. Mitsuri and the other Hashira's raise Asami to be a demon slayer, teaching her the art of breathing techniques and how to slay demons for the greater good of humanity.

This is what you'd ask yourself after an unwelcomed visit from the Devil, who flipped your world completely upside down, into the world of demons. Death seemed like the easiest option, but then a young, charismatic Upper Moon came to your rescue, taking you in and making you his, for forever. He was toxic, twisted and nothing but trouble, but the love that blossomed only could compare to that of a blue spider lily-beautiful and rare. Your gentle touch, and kind soul softened his heart, turning him into something unimaginable for someone so cold and broken. But a demon as pure as you, only had one fate, and it would take more than just love to evade tragedy. warnings in the first chapter ♡ #1 in #demon - 7/6/21 #2 in lust - 7/6/21 #1 in akaza - 7/31/21 #2 in #kny - 8/20/21 #2 in doma - 9/2/21 #1 in kibutsuji - 9/11/21 #1 in doumaxreader - 10/20/21 #2 in douma - 10/22/21 I do not own Demon slayer or any of its original characters.

DISCONTINUED- Storm (KNY X Reader) by AnimeMaster44

[DISCONTINUED] Becoming a Hashira was a rather big decision, one that took you years to make. People have always believed in you but you tend to push them away in favor of being alone. You view friendships and such as pointless due to how quickly life can end. Yet, a few interesting men just might change your mind. I would also like to note that since I have not read the manga, some things may be wrong or some characters might seem OOC. I apologize if you find that annoying. **this story has multiple love interests** ***this story does not completely follow the story line of the anime or manga. I have not read the manga so please do not comment spoilers.*** Story cover by @fuckudelilah
