You burst through Muzan's room, and there he was.
Muzan: (Y/N) (L/N), welcome to your doom.
(Y/N): Muzan. Why? Why are you doing this?
Muzan: Do you know how long I've strived to live for? I will live forever and dominate this world. A world of demons. But, my body can't last forever. Though, from what I've seen thanks to Nakime, you have this much strength and a much more powerful soul. That's why, I will take your body!
(Y/N): Like hell, you will!
You begin to attack as he extends his arms like whips and begins to attack you rapidly!
Muzan: HOLD STILL!!! DEMON BLOOD ART: BLACK BLOOD BRAMBLES!!!
He shoots out several prickly branches out of his body, and starts to attack you with them, and you dodge, and-
(Y/N): MOON BREATHING SEVENTH FORM: MIRROR OF MISFORTUNE, MOONLIT!!!
You enlarge the size of Enma, and swing a crescent slash, which sends many shockwaves, sending him back!!!
Muzan: ARGH!!!
He starts to swing his hands like whips, and you dodge using Ultra Instinct and-
(Y/N): SANTORYU FLAME BREATHING NINTH FORM: RENGOKU THREE THOUSAND WORLDS!!!!
You go to Muzan and smile as he stepped back a bit.
Muzan: What are you?
(Y/N): I'm (Y/N) (L/N), and I'm the World's Greatest Hero!
Meanwhile...
Nakima plays his Biwa and all of the Demon Slayers who are trying to locate Muzan end up dodging several pillars. They then hear a voice.
Tanjiro: Do you hear that?
Giyu: That's-
Mitsuri: (Y/N)!!!
Obanai: Did he say to-
Uzui: Yeah. There's a demon around here.
Sanemi: LET'S FIND AND TAKE HER OUT THERE!!!
Meanwhile...
You and Muzan start to attack each other as he can feel the burns on his body.
(Y/N): Muzan, you can't win.
Muzan: Don't be so sure! I WILL END YOUR LIFE HERE AND NOW!!! SHOCKWAVE ENERGY BLAST!!
A mouth begins to come out of his stomach and a scream and light emits from it, but-
You close your eyes, and then-
(Y/N): LIGHTNING BLADE!!!!
You pierced his stomach.
Muzan: BLEGH!!
He starts coughing up blood.
(Y/N): I hope you know that you're going to die here and now.
The room begins to collapse.
Muzan: No! This means ... NAKIME!!! SHE'S BEEN KILLED!!!
Everything begins to come apart, and you smirk.
(Y/N): You've lost everything, and now-
Muzan: DON'T YOU D-
All of your allies burst in and-
Muzan: NO!!!!
He begins to bulge up, as everyone attacks, and then-
(Y/N): It's over Muzan. HAKAI BREATHING: INSTANT DEATH!!!
You stab the Sword of Light into him, and-
Muzan: (Y/N) (L/N), I WILL RETURN! AND I WILL COME FOR YOU!!!
(Y/N): Sayonara, and give your regards to my son.
Light bursts from him, and he explodes.
The sun rises, and you guys had won ...
It was all over.
