In an alternate universe where the tides of war favored darkness, the Demon Slayers have fallen, one by one, until only silence remains across the lands once guarded by Nichirin blades. The Demon King, Muzan Kibutsuji, now rules the world from the shadows with an iron grip, humanity reduced to whispers and obedience. With the Corps obliterated and no Hashira left to resist, peace- twisted and blood-soaked, settles over the night. But as the dust of battle fades and the demons celebrate their reign, a startling truth is quietly revealed, For over two centuries, The Demon King has been bound in secret matrimony to his most loyal and powerful subordinate, Kokushibo, Upper Moon One. Their marriage, hidden even from the other Upper Moons, was forged not only in mutual ambition and bloodlust but in a strange, unwavering devotion. Now, in the ruins of the old world, where no one is left to oppose them, the demon lord no longer needs to hide what he once buried in secrecy. Whispers begin to circulate in the demon ranks. ... A world where love exists even among monsters, power intertwines with passion, and the victors are free to unearth secrets once kept in the dark. --- Created: 26/05/25 Ended: ...

The story of Kokushibo/ Michikatsu and Muzan Kibutsuji. ⚠️WARNING MY AU⚠️

Doma the club leader of drama club forces his two friends name Kokushibo and Muzan to be the main characters of his play that is about a Prince who goes on a adventure to find his true love or else his father will force him in a unwanted marriage, BUT anyway a little totally accident happens where Muzan plays as the maiden and Kokushibo as the Prince but it was too late.~ They had noticed that they starting getting feelings for each other

Set in medieval times, The Whipping Boy tells the story of how a spoiled prince and his cunning whipping boy escape kidnappers and become allies.

Short stories of romantic moments between the Demon King and his husband.

[ book 1 in the trilogy!! ] "Do not apologize for your fellow subordinates' incompetence, Kokushibou." Such a simple sentence that sent sparks flying between Kibutsuji and Kokushibou. Kokushibou had long lost any feeling he'd had when he was a human. But after working with Kibutsuji closely recently, he felt as though he may be experiencing some feeling. But will those feeling snowball into something more, or will Kokushibou be forced to awkwardly hide his feelings forever?

Muzan had lived for years, and in all that time, he had never been more entertained by a mere human. He didn't know he'd feel. He didn't know he could. And yet, when Michikatsu almost lost himself, Muzan saved him. Even though he was the cause. Warnings: toxic, manipulation, abuse, non-happy ending.

As the former uppermoons settle into their new lives as not-so-normal humans, two of them can't seem to shake the past off of their shoulders. Rui's mind is plagued with the desire to return to his demonic state. His frail body having returned after years of being a demon. Meanwhile, Kokushibo handles living with Muzan under his roof, linked to him in more ways than one. **THIS FANFIC IS THE SEQUEL TO SECOND CHANCES, AND I HIGHLY RECOMMEND READING IT SO YOU UNDERSTAND THE PLOT BEHIND THIS STORY** This book includes Kokuzan and Rui x OC 12/6/22 #1 kokuzan 2/6/23 #1 kokuzan 2/6/23 #3 knyship 2/6/23 #4 knyau 7/23/23 #3 knyau List of people who gave me inspiration/ideas for this: @Marumakua @Official_Kokushibo @chaotickaza
