Everyone has been training everyday for the big war getting more stronger ready to fight muzan. It been months since kagaya told everyone that muzan got a hold of kukiko and Tsuyoshi blue spider lily blood. Now yn and sabito are helping their kids because stronger. They become stronger to the point their hashira like their parents. (I'm not a manga reader so I make my own stuff) yn told everyone that she can teleport everyone to the infinite castle and kill muzan and the upper moon and how the castle work. Now everyone is making a plan how to kill the upper moon and muzan and ready to fight to the death.

"I'm glad I didn't end up like you father and mother knew if she took me with her I have a better life without you"-yn

Muzan growls and run to us. He so fast but I was quick enough to push everyone out the way with my tails and use my sword to stop muzan form his attack. We run up to him get a hit for him but he move so fast that only I keep up with him.

(This fight go on for an hour)

Muzan keep cutting off my lems but I keep growing them back. I covered in blood I look around and see giyuu sabito and my kids not move and I noticed how giyuu arm cut off. I look and see tanjion is standing in front of me facing muzan. I stand up and look at my sword see it about to break. Me and tanjion run up to muzan Dodging his attack get some hits here and there. I jump up dodging muzan attack but he grab my leg and pull me down. I look up at him and he open his mouth like he about to eat me. Muzan yelled in pain and he drop me I look up and see sabito and giyuu slice muzan back. I wrap my tail around everyone plus muzan and teleport outside the castle. I let go of everyone and throw muzan into a building. I noticed my broke but I didn't care I am a demon I can fight like them. Muzan stand up run at us again but he ran pass me and he about to attack sabito. Sabito wasn't fast enough to do anything. I run up to muzan and grab his leg and throw him until a few buildings.
