New Breathing Style (Ice Breathing)

Never Let You Die

Ichika's POV

I got to the demon Slayer corporation when I saw hashira's and master ubuyashiki talking to each other. I was out of breath but I tried to get their attention. "master ubuyashiki we need hashira's something bad will happen I can't say it yet but I hope you believe and come with me "I said when yui's owl suddenly appeared" the mugen train exploded they killed the lower rank 1 enmu but the upper rank 4 suddenly showed" what? upper rank 4? no, can't this be what yui says isn't right "what, upper rank 4? Oh no I think kyoujurou's life is in danger I think we really need to go there" the love hashira said then Mr ubuyashiki nod as we they follow and go to the place

Rengoku's POV

"I cannot understand why you're targeting a wounded person" I said to him so this is an upper moon he regenerates quickly... And there's this intense sense of pressure and dread.

"I thought he'd just get in the way between you and me" he said

"You and I have something to talk about?" I ask

"When I look weaklings, I just feel disgusted" he said and lower his head

"It's our first time to meet, but i already hate you" I said to him honestly

"Is that so? I really hate weak humans too"

"It looks like you and I have a different moral values in regards to things"

"I see then I have a wonderful proposal 'HOW ABOUT YOU BECOME A DEMON TOO?' I know your strength just by looking at you, your battle spirit is quite polished, you're getting close to supreme territory" he offer

"No chance" I disagree with a serious expression

"You're a pillar, right?" He asked

"I am the flame pillar, Rengoku Kyoujurou" I introduce

"Kyoujurou, I'll tell you why aren't you crossing into supreme territory, because you'll grow old. Because you'll die. Because you're human." He said then point me

"Growing old and dying is the beauty of the fleeting creature called a human being, you and I have different moral values no matter what kind of motivation I may have, I will not become a demon" I explained

"I see"he said then he used a technique "Destruction kill:compass needle technique deployment" he formed his self into a fighting Stan then a large snowflake appeared on where he stand "IF YOU WON'T BECOME A DEMON Then I'll Kill You!" he yelled at me with a scary smile then he run forward me "first style:sea of fire" I formed he's moving at a fraction of a blink the attacks reach me when he fire's into the empty air with his fists "fourth style:wave of blazing flames" I formed to dodged his attack I'll be dangerous for me to cut his head off if he fights me from a distance like he is now if that's the case then I'll have to get closer! I appeared Infront of him.

I noticed that tanjiro is going to help me "STANDBY, SOLDIER!! JUST TAKE CARE OF YUI-SAN IF HER WOUND OPENS, IT'LL BE FATAL!!" I yelled to him "Give it all you got! Focus on me! Don't mind the weaklings Kyoujurou!!" He insult "fifth style:flame tiger!!!" I formed then he formed also "destructive kill: war style!!! My body flew away "don't die on me Kyoujurou" he said
