Chapter 17: Infinite castle, Muzan.
------------------------------------------------------
Y/n bursts to the surface.
Y/n: Teneko.
Y/n sees teneko bleeding and a bump on her head covering her eye.
Muzan: She has soaked in my own blood during the attack. The amount of my blood is too much. It won't turn her into a demon. Like fatal poison, it will destroy his cells and she'll perish. Kamado Teneko is already dead.
Y/n takes off his mask.
Muzan: Eh?
Y/n throws his mask at the ground and it shatters.
Y/n: Muzan, the gods are sorry for you.
Y/n: They are sorry that they made the mistake of putting you against me. You will not die a honarable death Muzan.
Muzan: What!
Gina: Y/n, you can't run in.
Y/n: Eclipse breathing, type shadow, 17th form, Galactic collapse.
Y/n combines all 12 sun breathing moves with all 16 moon breathing forms into one attack and hits Muzan before he can kill Mitsuri but he still kills Obanai and Mizuki.
Y/n: Son of a... Wait. 13th form sun is made of all of the previous sun breathings combined.
Y/n: Eclipse breathing, type shadow, 15th form, Solar sun!
Teneko: Beneficent Radiance!
Teneko hits Muzan away from Kanao and Y/n prepares his sword.
Muzan: You look positively awful Teneko Kamado. This way, it's hard to tell which one of us is demon. You both make my skin crawl.
Y/n and Teneko: Let's finish this... Muzan.
Y/n and Teneko begin to use all the forms of sun breathing.
Muzan: You are weak.
Muzan throws Y/n into a wall.
Y/n: The moon's blood flow!
Muzan gets marked.
Muzan: Is this really your finishing move?
Teneko: Fake rainbow! Burning bones, summer sun.
Teneko begins stalling Muzan and Y/n gets up.
Y/n: Eclipse breathing, final form, Eclipse.
Y/n's sword gets enveloped by a black flame and Y/n makes a beam out of the fire.
Muzan: Why won't you die!
The black fire beam surrounds Muzan and envelops him.
Muzan: NO!
Muzan tries to fan away the fire but it starts to burn him.
Y/n: The fire is about to be gone.
The fire goes away and Y/n sees scars on Muzan's body
Muzan: How dare you!
Crow: 35 minutes until dawn.
Y/n: uh oh.
Teneko: Y/n! Muzan is dividing! He's trying to break into smaller pieces and escape!
Y/n sees muzan try but fail and cough up blood.
Y/n: I must win!
Y/n's blade turns pure red.
Y/n: Eclipse breathing, type shadow, final form....
Teneko: Y/n! No!
Y/n: The eclipse's light and shadow.
Y/n rushes in and stabs Muzan in the chest.
Muzan: There is no damage.
Y/n's katana begins to spread the fire in Muzan's body.
Muzan: AHG!
Muzan coughs out blood.
Y/n: The fire fused the sword with your body. It is stuck. The fire will spread through your body.
Muzan begins to cough out the black fire.
Y/n: You won't die... But you wish you could.
The fire comes out of Muzan's mouth making him cough out blood that is on fire. He releases a static shock that Y/n backs away from.
Y/n: You are just hurting yourself. The static shock will travel in the sword and then into you.
Teneko: Y/n, dawn is breaking.
Y/n and Teneko get launched and Teneko get's absorbed by Muzan's flesh shield.
Sateki: Idaten Typhoon!
The sheild gets slammed on the ground and Mei keeps muzan in the sun using the chains.
Gina: Constant flux!
Gina pulls the sheild into the sun and muzan finally dies.
End
