One by one the hashira arrived as gyomei fought Muzan. Y/n joined in as soon the other hashira did along with tanjiro.

Then gyomei yelled to his fellow hashira

"It's Muzan!! Muzan kibutsuji! Even if we cut off his head, he won't die!!"

All the hashira stare in shock and anger that the demon king was right in front of their eyes.

All of them prepared to attack him all at once

As all of them were about to attack, Muzan smirked and they all fell through screen doors making them all fall into the infinite fortress.

"DO YOU THINK YOU HAVE ME CORNERED? ALMOST ALL OF YOU ARE GOING TO HELL!! TONIGHT IS THE NIGHT THAT THE DEMON SLAYERS WILL BE NO MORE!"

Muzan yelled with a wide malicious smile on his face.

"YOU'RE THE ONE WHO'S GOING TO HELL, MUZAN! I'LL NEVER LET YOU ESCAPE I'M TAKING YOU DOWN NO MATTER WHAT!"

Tanjiro yelled at Muzan as he fell

"THEN DO IT! IF YOU CAN! TANJIRO KAMADO!!"

🤍

Your POV:

I saw a platform and I landed on it. I hated this place brought back to many bad memories.

'I think I'm getting dizzy.'

I looked around and saw sanemi just sitting...looking straight head, I could sense how devastated he is that the master is 'dead' I wanted to tell him the master is very much alive. But with those intense feelings will make his so determined to kill Muzan and others demons that may get in our way.

But I thought it might be good for us to stick together. So I started running towards him, but I saw a demon about to attack him. I thought that he might still be in shock and that he isn't paying attention so I drew my sword and yelled

"Shinazugawa-San!"

But he beheaded the demon quickly without getting up

'Oh I guess he's not in a state of shock.'

I quickly walked next to him. He got up and looked at me, I saw he was crying. Never in my life would I expect to see sanemi cry

"Shinazugawa-San..."

It absolutely broke my heart, but soon I got in a stance as I some more demons appear.

"Looks like they're coming one after another."

I said getting ready sanemi got ready too

"You filth! Bring it on! I'll kill every last one of you!"

We fought off the demons nearby but they just kept appearing

'angel breathing, seventh Form: scattering feathers'

That seemed to get rid of the last of them

"Come on let's get going!"

Sanemi yelled to me and I nodded and we both started running down the halls without knowing where we were going. Beheading demons along the way.

"I'm surprised your not crying your eyes out."

Sanemi suddenly said. If the master would've actually died I would've been absolutely crying my eyes out.

"As of now there is no time for tears. I have plenty of time to cry till my tears run dry and until I can no longer yell after we win."

🤍

Sanemi looked over at you. You were completely calm and focused. You had in mind in goal and your were determined to complete it.

'This side of her is a little strange. I've never seen her so serious about something. Even on missions she seemed so lively and a bit energetic. I've never seen her with such a cold unreadable expression.'

He though to himself then a question popped up

"Just in case I die I want to ask this-"

"Your not going to die Shinazugawa-San."

"You don't know that!-"

"Yes I do."

"How?!"

"Because I won't allow it. I won't let a dear friend to me die. Not as long as I am able to swing my blade."

He was shocked

"But what is it you wanted to ask me?"

"Why did you become a demon slayer?"

"Your really asking that now?"

"It just doesn't make any sense to me. You could've live such a peaceful, simple, non dangerous, life. Could probably get yourself a husband (thought: which after this is going to be me.) get married, start a family, and enjoy your life without any worry."

"...All my life I just wanted to help people. Just like my parents, I knew about demons from a young age. Since my parents were retired demon slayer; It's true I could've live a life just like the one you described. I could've turned a blind eye and do something else with my life. But I did not, especially after what a demon did to my parents and village. My only goal is for a world without demons, so no more lives could be destroyed...like mine. I truly believe that tonight we will be victorious and we all will be able to live the rest of our lives without demons. I would love to live a life were me and friends can live happily without worry."

You smiled lightly at sanemi. The aura you gave off was so happy and peaceful. If he wasn't so focused on the situation that was going on he could've fallen asleep right then and there.

🤍

"You three seem agitated."

The master said calmly to the demons that saved him, his wife, and two daughters.

"Yeah you could say we are really nervous..."

Douma spoke

"This is no doubt the final battles between demons and the demon corps. In full honesty I'm just really worried for y/n."

"I tried to convince her to...at least let me fight...but she refused...since all her fellow demon slayers...didn't know the full situation...she knew they'd tried to attack me...she was also worried...about us turning back into humans...in the middle of battle...if that were to happen...she suspects that we'd be to weak to fight...after changing back into humans."

Kokushibo explained to which Douma sighs

"She's not wrong. That would no doubt happen.  you'd also be the only one able to fight we have no Nichirin weapons."

Akaza added

"Do you any of you feel as if your bodies are changing in anyway?"

The master asked

"I'm getting a couple of weird feelings but nothing major, I'm just hoping if he does die that we don't die as well. Because if he dies all demons die."

Douma said nervously

"How long ago was the antidote injected into you?"

"...I'd say...right before y/n-sama...received the message...from the crow about his arrival..."

The master smiled

"I'm sure you all will be fine. I have a feeling the antidote will kick in any minute."

Just as he said that Akaza started feeling kinda hot and laid down

"Akaza? You feeling alright?"

Douma asked curious on why he suddenly laid down

"I just feel...really hot all the sudden..."

He said as if he was short of breath

Then douma started to feel it And then had to sit down

"Weird...now I'm feeling all hot..."

He also said almost out of breath

Kokushibo then thought it was a sign the antidote was working. He started to feel hot as well but kept quiet about it.

🤍

"Strange."

Sanemi suddenly spoke

"What's wrong Shinazugawa-San?"

You asked him

"Don't you think it's wierd we haven't run into an upper rank yet?"

He said looking around while beheading a demon then continuing running

"We've only run into minor demons. No upper ranks."

He added

"It is strange. They might be in different area of this place."

You quickly dismiss

"But there is a demon we need to worry about. The one that built this place. Her name is nakime, she controls the entire place. she can shape it as she so wishes with a strum of her biwa. she can probably also see everyone in this place since she can generate small eyes that can move around following people. It isn't too deadly just really inconvenient. She can easily separate us by suddenly-"

You were cut off by screen door opening on the floor below you

"Y/N-Chan!"

It closed before he could follow.

You landed in a room full of demons, you instantly knew what was up.

'I see. The goal is to weaken me as much as she can, too bad. These demons are incredibly weak.'

You took them all down no problem and you exited the room. But now you were alone

'Oh well...'

You were running around trying to find where Muzan is or maybe even nakime. While taking care of demons on the way or saving other demon slayers.

While running you noticed some crows flying around spreading news

"I hope Kiriya is doing okay."

You knew him and the younger twins kuina and kanato were navigating everyone and sending out reports. On the occasion that you'd visit the ubuyakishi family as the this day approached closer and closer Kiriya would say how stressed he was that he wasn't sure if he'd be good enough to lead everyone. To which you would hold him in your arms and tell him that he will be an amazing leader all he has to do is believe in himself.

"Huh?"

You look over and saw Obanai and mitsuri fighting nakime!

You saw mitsuri falling from on of nakime attacks without a second to waste you jumped and caught mitsuri

"Y/n-Chan!"

She blushed as you jump onto a platform putting her back on her feet

"You okay?"

You asked

"Y-yeah!"

She answered but then you both quickly jump out of the of a fall coming towards you two.

'Gosh. How are we even supposed to get near her? She's playing on both defense and offense.'

After fighting for awhile she strummed her biwa and you were transported from place to place. on the second last place she transported you, you tripped.

As you fell you closed your eyes but was caught by someone.

"Oh thank-!"

As you said that you opened your eyes and stopped yourself when you saw him. Muzan Kibutsuji!

He seemed ever stronger than before! That shook you to your core. You could sense all the slayers he killed before now. It only happened just a few seconds ago a dozen demons slayers killed!

He smiled at you

"I'll have to thank nakime for bringing you to me once again."

You tried to back away but he held you with one of his arms. You tried to get out of his grasps.

"Squirming is futile my dear."

"Let me go! You monster!"

"RELEASE HER!"

You both heard and you saw Giyu and tanjiro looking absolutely furious

"Tanjiro! Tomioka-San!"

You yelled while trying even harder to get out muzans grasp but he just tightened his hold

"You're so persistent. I'm getting sick and tired of you all...and I'm losing my patience. You're always tapping about avenging your parents your children or your siblings."

Then he said something that angered all three of you more than you all already were

"Isn't it enough you're still alive?"

The air became deathly still and it became so quiet you could hear a pin drop.

"So what if I killed your loved ones? Consider yourselves lucky and carry on with your lives."

Tears were pouring down your face. He was so heartless!

"How can you say that?"

You asked in a whimper. He wiped the tears from your face. Tanjiro and giyu were ready to attack him but he started talking again

"Think of it as if they simply met with some natural disaster. There's no need...to make it more complicated than that. Rain, wind, volcanoes, earthquakes...no matter how many people they kill, no one seeks revenge against them."

You couldn't believe what he was saying. He was comparing himself to natural disasters. You believed that he must be out of his mind.

"Besides, the dead will not return to life. Let go of your grudges. Just go about your business and live a quiet life. That's what most people do. So why don't you? There's only one reason."

"Because demons slayers are abnormal."

"And I'm tired of dealing with you. I just want this to end."

It was dead quiet. As you struggled you looked over to your comrades. Tanjiro's expression scared and surprised you.

He looked so emotionless with a dead look in his eyes. The aura he gave off was shivering cold, colder than ice. And the amount of hatred that he was giving off. I've never felt so much hatred from a person.

"Muzan...we...cannot allow you to exist anymore!"
