It's Our Misty Void [Muichiro x Reader]

Demons VS Demon Slayers pt.2

The fight between the Upper moon 1, Kokushibo VS the void pillar, Y/n Kamado and the mist piller, Muichiro Tokito begun.

Three of them backed away and now their position were in triangle shaped, Y/n and Muichiro ready to attack Kokushibo and Kokushibo, standing in defensive stance as he is ready to slash anyone who dare to attack first.

Muichiro took a few step aback while Y/n moved forward taking slow and cautious steps towards the upper moon. Three of them tightened their grips on their swords while at once everything covered in mist and void.

"Void breathing 4th form : Endless Void"

"Mist breathing 5th form : Sea of Cloud and Haze"

"Moon breathing 2nd Form: Pearl Flower Moongazing"

These three chants was chanted by their respective users as the mist and the void covered the whole room and even destroying the rooms around it while it looked like as if those there were transported to another dimension which is filled with mist. Upper 1's attack also caused damage around them by both Y/n and Muichiro dogged his slashes.

The tension between them thickened as they all backed away once again to regain their stance. 

"What type of thing is this?" Upper moon 1 growled when he realised that the void was still casting.

"Something that no one can escape until and unless I want to." Y/n replied with a hidden smirk behind her emotionless expression.

Muichiro frowned slightly, this was his first time seeing Y/n using this form. He had only heard rumors about this form but now really seeing and feeling it on his own. Though he was surprised by her sudden change in aura as her aura was suddenly almost at the point of 0 out of the blue, he brushed off those thoughts and focused on the situation in front of him. He looked at Y/n for a signal as both of them circled Upper 1 and taking steps cautiously.

"Mui! Now!"

Shinobu POV :

Upper moon 2... Now I'll be able to take our parent's revenge...

"My,my, a female slayer, huh~? Most likely a hashira~ What a luck I've today~" The upper rank cooed while hiding his face behind his golden coloured fan.

"This will be your last day in this world, Upper moon 2." I said with a frown and anger look in my face. Yes, he is the one. The one who killed our, my and nee-san's parents, when we were kids.

"A feisty one huh? Let's see, what you have got, young lady." Said the Upper 2 before both of them took their fighting stances.

I dashed at him with full force but before that, I took a long deep breathe... The air inside this room is highly dangerous to breathe in... It's almost freezing here. If someone breathes in this air, his/her lungs would get freezed in an instance and will result, immediate death.

"You aren't fighting alone, little sis, I'm also here." Said the one who helped me to stand up as a moment ago, this upper 2, fleed me towards this walls with his ice blows.

"Nee-san..." I muttered out.

"Let's take our revenge, sis..."The slower pillar, Kanae, said while holding out a hand for me to take and stand up.

"Yes, nee-san." I said while taking her hand and standing up.

Tanjirou POV :

I and Giyuu-san made our way to find Muzan and Lady Tamayo, after killing that demon whom we encountered just after falling inside this never ending castle. Suddenly, the floor above us starts to shake.
