.... Giyuu Tomioka x FEM Demon Y/N

The Final fight begins |1| (Part 29)

"Best Friend? Just who do you think you are?" Chizuki was visibly enraged. It seems like the name Hayami triggered something in her.

"It's me! Akemi! Don't you remember my name? Your Best friend's name?" Y/n was yelling and so was Chizuki.

"You're not Her! You're not my dear kemi! It's simply impossible!"

"I am her! She's my past life!"

"Can you two stop this confusing argument? We are supposed to wipe out these slayers, so why are you two arguing?" Said by Muzan with an annoyed tone.

"I apologise Kibutsuji, it's just your toy. She's pretending to be someone I knew."

"Master, please let us live in peace. We can talk this out!" Y/n pleads.

"Do you think I'll be able to live peacefully if I can't walk out in the sun?"

"Why is walking in the sun important anyway?"

"It's been my lifelong dream ever since I became a demon.. Since I could not walk out in the sun when I was human. I was a pathetic frail fool."

"Then master, I shall choose a side in which I'll help."

"Suha, my little fool. Do you think you have a choice here?"

Y/n then walks up to the Hashiras, the group became tensed and unsheathes their blades bracing for an attack. But instead, Y/n held Tomioka's hand and lifted it up.

"I shall choose this side! We shall all come together for the sake of peace."

Although it was unexpected the slayers cheered on and became hype. Soon started the fight they've all been preparing for.

But the slayers knew they were in a disadvantage, the sky was totally blocked out by the blood demon art of the former upper two, which resulted to dark sky; No trace of sunlight at all.

They all accumulated a plan to attack this woman called Chizuki first. In the frontlines, the Hashiras and Y/n are present. Although they split up in the end to make muzan busy, Tanjiro came to help the side to defeat Chizuki.

Moments passed by and some are exhausted, but they all tried to push through to achieve victory.

"You cannot defeat me Suha!" Chizuki grins.

"I cannot alone, but with my companions I can." Y/n replied calmly.

She really has nothing to worry about. A demon cannot kill another because of their own regeneration. But with slayers and the sun breathing by Y/n's side, she knew she'll achieve victory.

Her power is to control and manipulate, she received an abundant amount of blood from Muzan which strengthens her power; And to combine with her years of experience all could tell she's one of the tough cookies to defeat.

By all means to control and Manipulate, Chizuki hypnotized some of the lower ranked slayers and made them fight their own kind. Soon, they all realise it was all because of a bloody red moon behind her. If a slayer were to spare a glance at it, they were easily then controlled by the demon. All observed the attacks of their former allies, paying great attention not to accidentally kill them.

Chizuki was in an advantage, all could see. Though she fights alone, she has a rare power that instantly gives her control over the others.

Tanjiro who thought of an idea and wanted tell the others could not find a time to do so, it seems like more and moe of his companions are attacking him. As if Chizuki was paying great attention of his Sun Breathing.

"Y/n-chan! I need help!" Tanjiro yells. And back-up came, it was Y/n.

"Are you okay? Can you still hold on? If you can't anymore go take a rest I'll handle the rest."

"No Y/n-chan. We need to initate my plan."

"Plan? Sure please tell me."

And so the plan was explained to Y/n and she then told the others about it and agreed.

"Hayami! Please listen to me!" Y/n starts.

"What's there to talk about? Do you really think we have anything to talk about?" Chizuki yells back.

"You can come over and join me on their side! Please! For me Hayami!"

"No! Nothing will stop me from being the strongest woman!"

Suddenly, her head fell off. Chizuki was surprised that her head was detached from her body for the first time. She then sees who could it be, it was none other than the Successor of Yoriichi, Tanjiro Kamado.

As she fades away in defeat, she couldn't help but leave in tears. Her blood demon art slowly fading, the slayers got control over their body once more.

"I never intended to kill you, Hayami. It's just that you've become whom you hated when we were little children. How did you even turn away from the light?"

"YOU DON'T HAVE A SAY IN MY DECISIONS IN LIFE!" Chizuki yells for the last time before her body completely faded away.

With Chizuki eliminated, the dark sky that she made was gone. Soon, the sun slowly rised. All was now against the Demon King, their last sworn enemy.

"Do you think you have what it takes to defeat me?" Muzan says.

"By fighting together, we believe we can!" The Love Hashira speaks out. Even though she's visibly shaking because of fear.

And so the Final fight started.
