The winter vs the butterfly

Last time in I was reborn in demon slayer as an uchiha

The entire castle shook, the vibration of the explosion was even heard outside the castle and all throughout Japan.

No one knew what made that noise, as the explosion was going on, I look at the center of it and watch a his body got disintegrated but it never truly vanish, his regeneration kept him going, I then release my Uv light seal and threw it in the explosion.

"I will kill you"I heard him say and as the explosion died down I saw it, around him, there was some sort of armor protecting him.

He looked a bit beaten up and he was regenerating, I looked at the gigantic figure that was protecting him before a sweat fell down my forehead.

'You got to be kidding me' I though as I looked at the Susano.

His body was already fully healed and all his wound were gone but now I could now fully see all the sharingan,he had implanted on his body.

Now we continue where we left off

"How far are you willing to go" I said as I look at Muzan.

"Very far"He answer before his hands turned into thunder, he then tried to strike me.

I dodge it and the spot that I was on was destroyed completely.

I then duck as a photon wave by me.

"when the fuck did you get that"I said as I realize that his attacks will now be all at lights speed.

"you don't need to worry about it"He said as he started launching more precise shot forcing me to use more power.

I wanted to gauge his strength so I could kill him in one shot.

All his attack and his strength were so fast and strong that a hit from him would actually injure me.

This was a new though to me, I did not get injured since the last time I got jump when i was thirteen.

I started to bombard him with Jutsu, chakra was not an issue for me considering how much I have.

I use gwntjutsu when I could and even something use shunshin to get away.

The battle was closer that I expected but time to turn this up a notch.

A green aura surrounded my body as I had opened the first and second gate, I was now much faster and much stronger than before but I could manage to destroy his susano defence.

I didn't even manage to even leave a scratch.

I breath in deeply before rushing toward him again this time with a new strategy.

While Atoru and Muzan we're clashing and going head to head.

The Hashiras we're all struck in a sticky situation of their own.

Pov Shinobu.

As Shinobu was running from place to place she came in a room that had a pond in it, inside the room a demon sat down and was chopping down on some girls.

He seem to notice her as he turn around and said"Hello there, are you here to join my religion"

He looked happy as he said that and then he seem to have sniff her because how his nose moved.

"You smell like him"He said suddenly becoming serious.

"Master Muzan would be very happy to have your head"He said smiling happily.

Shinobu just felt angry at watching this demon eats those girl without mercy not remorse.

She immediately open activated the heavenly breath technique, her eyelid disappear as a yellow aura surrounded her.

She dissapear from her spot and broke the plank underneath her as she move.

Doma eyes widen as he realize he will have to take her a bit seriously.

He moved his body out of the way but her speed made her reach him before he fully dodged so half of his body was gone.

He looked at her and he said"Naughty girl you shouldn't do that"

Even if he had just lose half of body, he still didn't look worry.

Shinobu continue to attack him and he blocked and doged most of her strikes.

He actually had to pay attention to her and he couldn't just joke around with her because he could die, the though of dying didn't scare him he just though he will just disappear.

He release his blood demon art in the whole place was frozen over solid. Shinobu manage to escape unscathed but the place was now slippery but it was alright because Atoru taught her how to fight in slippery places.

She then applied more force into her attack and started dominating Doma completly.

Doma used his ice Buddha to stop her from attacking him.

He also created a lot of new ice clones, he made a lot of ice flowers that shot projectile at her and threaten to freeze her lung solid.

She continue to dodge and fight Doma on a more equal term.

Doma did manage to land a few hits on her that look like they did damage to her small frame.

But she looked like she just brushed them off before she started to fight him again.

It's just as Atoru predicted even if she was small she could take in a lot of damage, he made sure if that everytime he sparred with her.

He wanted to make sure she doesn't take to much damage from one hit and now after nearly 3 years of training, she could tank as much damage as Sanemi could in the canon timeline.

It was more than likely that she could tank more but tanking wasn't her speciality, speed and agility was her specialty.

She was very fast and as she move the floor beneath her was getting destroyed.

"Insect breathing dragon fly thrust, "Shinobu said as she reached Doma.

She used all of her speed along with one precise attack at Doma that blew Half of some body away.

She also injected a new poison that she been working on inside Doma body.

Doma felt the effect immediately but for some reason his body didn't try to nullify the poison.

When she looked back at her she just gave him a weird smile while saying "you won't be missed"

He felt the intense pain that he was going through but the only thing he could notice now was how pretty she was. (A/N I checked his personality file and he would be thinking that right now and if not then let's just he is a bit different here)

"You look so pretty, I wonder how you will taste like when I eat you" he said looking at her with a smile on his face (A/N that the doma I know)

A/N I thought it would be weird if Shinobu lost easily, she has been with Atoru for a while and he seemed like the type that would make sure she is stro
