In front of you was Tanjiro with Hinatsuru behind him "You damn brat keep getting in the way!" you yelled angrily as he started to cough. "Kill him" you said coldly once again the demon wa right in front of Tanjiro about to attack him when he blocked him using his sword and there the Hashira was right in front of you about to cut the demons head only to be blocked by his sickles. He was about to stab the demon with his other sword when he suddenly turned his head around biting the tip of the sword activating his blood demon art when without thinking you ran to them pushing him and the demon off the roof as Hinatsuru pulled Tanjiro to avoid falling off. 

Just at their side appeared Inosuke and Zenitsur who were still trying to fight of the obi. They told him to change strategies and let Tengen handle the demon guy. Unsure of what to do Tanjiro looked at the scene below them as both the demon and Tengen were deflecting each other's attack while you couldn't be seen. Before the obi could fully wrap itself on him he used his water breathing to cut them off agreeing to their plan to decapitate the demon girl first. 

Earlier you unconciously ran towards the demon pushing him off as Tengen pulled you guys off the roof. "Y/n! Are you okay?" he yelled not seeing you until the dirt cleared showing you pinning the demon down."Y/n!" he called out once again. "Oi, What are you doing?" the demon said pushing you off him easily as you were feeling weaker and weaker. "I don't know." you simply said struggling as pain started to spread all over your body. 

When you saw the girl being grabbed by Gyutaro earlier a memory flashed in front of you feeling a stabbing pain in your heart. Another one more painful feeling when you saw Tanjiro as a memory flashed. Until you saw Tengen once again in front of you so close as you could hear his voice clearly. You could finally go free from the shackles that were pulling you towards the dark ever since you woke up. During the time just from when you woke up, in reallity all you could feel was darkness. Your memory was cloudy and all you could think about was what Muzan has said inside your head.No matter what you did you couldn't break free from his strings. But when you saw Tengen in danger in front you , your broke the two strings in your arm and feet. 

And now here you are in pain once more as you could feel not only a stabbing but also a burning sensation inside you as you coughed up blood. Gyutaro feeling something different about you and with Muzan's cells telling him, he  kicked you away so strong towards another building as you bled more along with the new injuries you just got. More of your blood was exposed as both the upper rank 6 demon could smell your delicious blood getting them more hyped up. "The girl Y/n is no longer useful to me, defeat the hashira and kill the hanafuda boy then can you eat the girl just bring me enough of her blood." Muzan said in both their heads as they smiled excited to eat you already.  

"Damn it the situations gettin worse. I thought it wouldn't be a problem of Y/n getting killed but now that this demon just kicked her away must mean they don't need her anymore. Shit!" Tengen cursed inside when the dmeon suddenly attacked him. "I'll have to kill you earlier than planned so I can eat the girl already." it said as his attacks were getting stronger. You tried to stand up but the pain inside you was strong. You tried to think of why this was happening when you remembered the night you saw Muzan again. Befire he made you unconcious, he injected something inside you. YOu knew it was blood since he didn't want to contaminate your blood with his but instead in seemed to be poison thst contained some of his cells that he was able to extract from his blood which was actually quite hard for him since it was the first time. What he injected to you is basically similar when he turns someone into the demon except your not a demon but your memories are latered and his cells are inside which made him able to control your mind. 

At the same time, Inosuke started to rampage towards the demon girl with the other two covering him from the obi's so he wouldn't be distracted. Until he finally reached the demon placing both his blades at each side of her neck and started to cut her neck using his twin blades as a saw. Finally her head was cut off  as he catched it and started to run away but then suddenly behind appeared Gyutaro as he stabbed Inosuke with his sickle grabbing her sister's head leaving Tanjiro shocked. "Why is he here? WHere is Uzui-san?" he thought as he looked at the ground and saw you and Tengen laying on the floor with his left hand cut off. 

"Tanjiro, watch out!" he heard Zenitsu yell who was running to him pushing him off the roof with the obi's attacking slashing the buildings breaking them all down. 

Earlier

Despite the pain you were feeling you tried to walk back to Tengen and the demon when you saw them fighting. Using all your strength you used your bladed fan stabbing the demon at the back only to be stabbed by his sickle kicking you a bit far away again, avoiding Tengen's attck and cutting his hanad off before finally going to Inosuke to get her sister's head.
