Your's POV:
Me & the others were still fighting against Muzan Kibutsuji. He was trying to kill us all but, we keep on dodging his attacks.

"Y/N! We need to hold them off until the Sun will rise! It's the only way to kill him!!" Kyojuro said as I nodded at him. I run towards until I punched Muzan in his stomach and, he ends up coughing up blood again too.

"Just die already, Muzan!!" I said to him as I pulled out my Kusarigama. "The Sun is rising!!" Muichiro said as we all saw the sun rising. Muzan the sun too, fear took over him.

Muzan send another powerful attack as he trying to get away from the sun. That motherfucker not going anywhere! I'm going to make him suffer, what he did to the innocent lives!

"You're not going anywhere, Muzan!! Don't keep the devil waiting!!" I said as I was about to attack him until someone threw a nichirin sword to me. When I look at the the person, who gave me the nichirin sword. It was Haganezuka. "Hurry, Y/N! Kill that bastard!! Kill him for, what he did to everyone!!" Haganezuka said as I nodded at him and, I quickly grabbed nichirin sword. I run towards Muzan until I stabbed him in his stomach as I pinned him against the wall too.

"Remember what I said to you, Muzan?! You're not going anywhere, you little shit!!" I said in anger as I was determined to kill until Muzan roar in pain and, he turned into an ugly huge baby too!

"You're one ugly motherfucker, Muzan!" I said to him as I sound like a crazy woman. I quickly backed away before, I can get hit by him. "Muzan is trying to get away!! We have to stop him!!" Tanjiro said as I threw my Kusarigama at him as the chains wrapped around him.

"I need help to pull him down! So, Muzan doesn't get away!!" I said to myself as I was pulling the chains with my strength until Gyomei helped me out. Even, the other demon slayers too.

"Don't give up everyone!! Muzan is almost dead!! Don't give up!!" I said as all of us were still pulling the chains as we were preventing Muzan to find shelter. "I'm not going to stop! You hear me, Muzan!!" I said to him as we keep on holding onto the chains until Muzan screams in pain as the sun was finally in the sky.

"You finally die, Muzan... enjoy staying in hell..." I said as all of us watched him turned to ashes until he was gone. "We did it... WE DID IT!! WE FINALLY DEFEAT MUZAN!!" They said as everyone cheered in happiness.

"Everyone's free... I'm so happy... I wish my friends are family with you to see me" I said to myself until everything went to darkness.
