She was Muzan Kibutsuji's creation - but against his own design, she became something more.
Muzan Kibutsuji has made countless demons, but none like Ayame Fujiwara - a noblewoman discarded by her husband and left to waste away in sickness. Drawn by her quiet defiance and fragile beauty, Muzan offers her his blood, not as mercy but as a challenge: do not break.
When Ayame rises from weakness into power, Muzan finds himself treating her with a courtesy he shows no other, a dangerous tenderness that blurs the line between master and consort. As her Blood Demon Art blooms in thorns and poisons, their bond deepens - not only through blood, but through forbidden sparks of desire.
In the shadow of the Sengoku era, a new story begins: one of vengeance, blossoms, and the peril of loving the man who embodies darkness itself.

To Make Things Right Again
Muzan Kibutsuji, the demon king. At last, the demon slayers have succeeded in his murder and gotten their happy endings. We all saw how their stories concluded past that final battle, but we've never heard of Muzan's side. What if his story wasn't over? What if he got a second chance, just two years before his death, to make things right? Essentially the story of Muzan choosing to be good, befriending the demon slayers, and trying to fix thousands of years of wrongdoings. All characters (excluding Sayaka) are the property of Koyoharu Gotouge and not my original concept. Cover art belongs to Displate, not mine. Book Two coming soon!Complete
My Lady (KDH x Reader)
The woman sat under the roof of the house watching the rain come to an end. Blood dripped from her hands, though it wasn't her's. She moved away a bit from the sun light not letting it touch her. She sighed as she placed her hand on her face, staining it with blood. - "Lady Muzan, will you be alright here?" A dark figure asked the familiar woman, though instead of a kimono she wore a hanbok. "Does it look like I'm helpless, Kokushibo?" She said as she turned to see the six eyed demon. "And don't call me Muzan, it's Y/n now. Besides that name was only a cover up." She said as she turned away from him to look back at the town before her. - "Y/N Kibutsuji." "Make sure to never forget to fear it." - (P.S Kpop Demon Hunter doesn't belong to me, and Demon Slayers doesn't belong to me either. This is just a fanfic, the story will involve most characters from both the movie and the anime. They might all be a bit ooc so don't take anything to heart. And this is a bit yandere kdh x reader.)

Jealousy
Muzan x reader The greedy lust circulating around him was suffocating, his cock straining against his trousers, he glanced at the demon fucking you, hating how he seemed to enjoy the feeling of your pussy wrapped around him. Your breasts bounced aggressively as you and Akaza's hips collided respectively. You could tell he was enjoying himself from the way his cock pulsed from within you, it seemed to grow more every time you clenched yourself around him. Muzan slowly swallowed a ball of saliva when you made eye contact with him once again, moaning out when Akaza hit your spot, his mind closed with desire. He knew you belonged to him, he had to make sure Akaza wouldn't cum in you or kiss you, he had to make sure to mark you before the red-haired demon even thought about it. "Hngh Akaza~" That was enough, Muzan had had enough. His possessive behaviour had overcome him, the fact you were moaning another man's name lit a fire inside him, he hadn't thought you were going to moan the same way you did with him this a book i made after this one shot that o wrote not long ago. it has smut and might have triggering topics. I decided to write this at 3 am ill think of a storyline later.Complete

Kibutsuji Muzan, the Demon King. The first of his kind, and the progenitor of all other demons in existence. A cold-hearted, ruthless, intimidating, and exceptionally intelligent individual who sees no value in sympathizing with anyone despite having seven hearts. Even his subordinates show no value to him. He merely sees them as pawns to do his bidding. However, there is one particular individual who he really cares for. And it was none other than his cute little brother, Tanjirō. The one who captured all of his seven hearts with just a smile. 𝗗𝗶𝘀𝗰𝗹𝗮𝗶𝗺𝗲𝗿: 𝘛𝘩𝘪𝘴 𝘪𝘴 𝘢 𝘸𝘰𝘳𝘬 𝘰𝘧 𝘧𝘪𝘤𝘵𝘪𝘰𝘯. 𝘈𝘯𝘺 𝘯𝘢𝘮𝘦𝘴 𝘰𝘳 𝘤𝘩𝘢𝘳𝘢𝘤𝘵𝘦𝘳𝘴, 𝘣𝘶𝘴𝘪𝘯𝘦𝘴𝘴𝘦𝘴 𝘰𝘳 𝘱𝘭𝘢𝘤𝘦𝘴, 𝘦𝘷𝘦𝘯𝘵𝘴 𝘰𝘳 𝘪𝘯𝘤𝘪𝘥𝘦𝘯𝘵𝘴, 𝘢𝘳𝘦 𝘧𝘪𝘤𝘵𝘪𝘵𝘪𝘰𝘶𝘴.
