Charisma (KNY/Demon slayer x male reader)

"What the hell are you talking about?!" Sasumaru demanded. "You're just an escapee!"

"That man is but a coward" Lady Tamayo said calmly. "He is always scared"

"Shut up you bitch!! Shut up!"

"Do you know why demons cant work together? Or why they kill each other? Its to prevent himself from getting attacked. You're being manipulated" she continued, her peaceful stature not budging. 

"Shut up, shut up, shut up! The great one is not a minor villain like that!!" Sasumaru screamed. "The great ones power is incomparable to anything and anyone else!! He is stronger than anyone!" Yushiro's eyes wanders to Lady Tamayo's arm, which had blood trickling down it. "Kibutsuji-sama is--!" Sasumaru slapped a hand over her mouth at the realisation of what she just said. 

Lady Tamayo solemnly raised her arm, revealing her bloodied hand. Tanjiro looked dazed. In absolute terror, Sasumaru ran to an area in which the grass blades bathed in tranquil moonlight. Very not suitable for what was about to happen next. "You shouted out his name" Tamayo narrated. "Now the curse will activate. How sad... goodbye now" she muttered. 

"Waah!" Sasumaru wailed and dropped to her knees. "Please forgive me! Please forgive me! Please! Please!! Forgive--!" she didn't get to finish as a hand erupted out of her mouth, surely shattering her jaw in the process, and another one ripped past the flesh on her torso. The hand in her mouth, latched onto her skull, crushing it in 1 blow. Gory squelching sounds and Sasumaru's agonising screams echoed as she reduced into nothing from a curse set by her own hero. The whole scene was so shocking and disgusting that Nezuko dropped the blade out of her mouth, letting it fall to the ground. Y/n looked grossed out as well. Lady Tamayo stepped out and crouched by 1 of her eyes balls, observing it. 

"Is she dead..?" Nezuko asked carefully. 

"She died in an instant. That is the power of Kibutsuji's curse. His cells destroyed the body of the demon from within. Basically, fights between demons amount to nothing. Apart from sunlight and the blade of a demon slayer, nothing will cause lethal damage to a demon. However, it seems that Kibutsuji is capable of destroying demon cells..." Tamayo explained. 

Yushiro suddenly appeared in front of Nezuko, slapping a cloth over her face. "Dont breathe in Tamayo's technique! It's harmful to humans!"

"Nezuko" Tamayo piped up. "She wasn't a part of the 12 Kizuki" Nezuko's eyes nearly popped out of her skull. "If she were one of them, her number would've been carved on her eyeball. As you can see, she doesn't. I'm afraid the male wasn't a part of the 12 either. He was too weak" she took out a small syringe and extracted some blood from the brain. "I have collected blood from both of them. I will now examine Tanjiro and Y/n with the medicine. They breathed in a lot of my technique as well. My apologies"

"So there are demons that have gone round the bend as well" Yushiro spat. "She dared to harm Tamayo's beauty. Its what she deserves" he removed his hand from Nezuko's face. "I'm not covering your ass any longer!! Get a cloth and cover your own damn face! I'm not leaving Tamayo's side!" he got up to his feet and started running to Tamayo. 

Nezuko laid there with a cloth over her mouth, gazing at the demons dead body. 

"...ma...ri..." the remainder of Sasumaru managed to breathe out. Nezuko quietly struggled to her knees, rolling the ball over to the demons side. 

"Here it is..." she muttered. 

"Come... play..." the demon whimpered. 

They didn't get a chance to play. The remainder of Sasumaru's body deteriorated when the sun came up, leaving behind nothing but the grass blades stained with her blood. Nezuko silently lowered the cloth, lost in her thoughts. She stood up and moved to the nearly destroyed house. "Tamayo?" she called out.
