Ruination Book 1: Tanjirou's Destiny
[Muzan x Tanjirou] For one thousand years, Muzan's goals have remained straightforward, and even now, his intentions with respect to Tanjirou are simple: . "I don't merely want to kill him. I want to ruin him," Muzan muttered to himself. "He will feel a pain equivalent to the loss he has caused me..." . But this task would not be as easy as he presumes it would be. Tanjirou, though small in stature, is blessed by the gods with a willpower that has the strength to rival all else. They are two souls locked in a battle for revenge, with neither intending to give up. The prize? Tanjirou's mind, body and soul. Muzan's goal is to dominate him. Tanjirou's goal is to protect his friends. As the cruel and egotistical master of all demons commences his dance of death with this pure, kind, yet resilient boy in a sadistic waltz for victory, who will win? And what will be discovered along the way? This is the story of Kamado Tanjirou's ruination... 《Word count: 61, 313》 .....................................................................

Our Bond Can't be Severed by Anyone!
It was unfortunate when Tanjiro twisted his ankle but Nezuko was all too willing to take the charcoal to town in his place. She returns home to a blood-covered scene that makes no sense. She reunites with her brother who is no longer human and shares only a few words before disappearing: "Hide... he'll find you!" Nezuko, wearing her beloved brother's hanafuda earrings, vows to become a demon slayer and find her brother and save him from the monster known as Muzan. How will the course of events change? WARNING. This. Is. Dark. Includes blood, gore (this is demon slayer y'all), force-feeding near the end, angst, lots and lots of angst, mental manipulation, Muzan Kibutsuji is a motherfreakin warning okay! Also, language. Warning: I am FIXING things. People are going to survive. Kyojuro is going to see his little brother again! Sanemi WILL hug his little brother. Kanao will NOT lose her other sister! I FORBID IT!
