Kiriya: (Upper One has been defeated and the remaining demons are few in number and our casualties are even less it's almost unbelievable currently it seems as if we're winning it's all I can take to not get excited I must stay calm every emotion can wait until Muzan is finally defeated) 

Kanata: Himejima has almost arrived at where Muzan is located as ordered he has continued his pace to Muzan once the Tsugikuni were confirmed to have arrived and the Tsugikuni brothers are close behind along with Tokito and the Shinazugawa brothers

Kiriya: (Tsugikuni we owe your family everything if not for you . . . I dare not think of where we would be now we're so close so please JUST A LITTLE MORE)

Meanwhile, the Cocoon of Muzan was shaking

He burst out of it only to find the surrounding area empty of any Demon Slayers he had a look of shock

Gyomei: Stone Breathing Second Form: Upper Smash

Muzan was caught by the attack and cut in half but regenerated slowly

Gyomei: I see so you didn't have enough time to fully overcome the poison but you rushed out regardless that must mean the other Moons have been defeated haven't they

Muzan said nothing as he dashed towards Gyomei in an attempt to kill him

Rimuro and Tanjiro: TWIN SUN BREATHING NINTH FORM DRAGON LEO

A powerful attack of twin dragons sliced Muzan apart though he regenerated quickly

Rimuro: There you are you bastard

Tanjiro: We will kill you for all the lives you took including our family

Muzan couldn't stop sweating knowing both of the very last people he ever wanted to face in combat were in front of him not slowed down or worn down by the other moons in the slightest but that still would not stop him from fulfilling his ambitions he attacked the brothers with several of his extended limbs but they were easily cut to pieces by Rimuro and Tanjiro which Gyomei then smashed the head of Muzan with his mace at that point Sanemi, Muichiro, and Genya arrived

Sanemi: Where's Muzan I thought you said he was this way 

Rimuro: We've been duped he was a fake we need to search for him

Tanjiro: All I know is that he's out of smelling distance so he's far

Rimuro concentrated his Universal Perception in an attempt to find him until he succeeded 

Rimuro: FOUND HIM

Rimuro dashed off to his location

Gyomei: RIMURO DON'T BE HASTY

Sanemi: HEY WAIT UP

Rimuro was leaping from building to building faster than the others

Tanjiro: BROTHER WAIT

Tanjiro tried to keep pace but Rimuro was unrelenting in his speed 

Tanjiro: (He's faster than usual I can't keep up . . . why is this so familiar . . . I see it's always been like this . . . I've always been too slow to properly help Brother and looking at his back as he does something amazing has always been what I've done)

Memories of the past couldn't help but flood Tanjiro's mind as he looked at Rimuro's back trying to catch up it merged with a memory of the past

It was a time when Nezuko was still a baby Rimuro and Tanjiro were walking alongside their mother when a wild boar appeared it leaped at them but before anyone could do anything else Rimuro jumped in front of the boar and punched it through several trees until it finally stopped at a stone wall cracking it

Kie: Rimuro are you alright

Rimuro: I'm fine my hands are a little sore 

Tanjiro: That was amazing brother you saved us

The infant Nezuko was giggling Kie held Rimuro's hands

Kie: Oh you poor thing you've bruised your hands please be more careful 

Rimuro: Sorry Mother (This body has strength but it's still fragile I need to remember that)

Tanjiro: Big Brother you're amazing

Rimuro: Heh thanks for noticing

Kie sighed

Kie: Please Rimuro I know you have gifts but don't be reckless with them

Rimuro: Don't worry I won't 

Rimuro looked and Nezuko as she was giggling at him while holding her hands out Rimuro let her hold his hand

Rimuro: Above all else, I just want to make sure that we're all happy

Tanjiro: (That's right brother has always been like that strong and always wanting to make use of that strength for the good of everyone around him but I'm too weak to help him)

Another later memory reached Tanjiro he was making straw boots with Rimuro and their Father Tanjuro

Rimuro: Father I wanted to make a request

Tanjuro: There's no need to hesitate to ask me anything, Rimuro

Rimuro: I wanted to do The Dance of the Fire God this year I've been practicing and I can do it I promise it will be no trouble

Tanjuro: Thank you Rimuro but the Dance has never been difficult for me I can do it again

Rimuro: I know but I want to do it I promise I can

Tanjuro: Well I suppose I can see what you have learned

Tanjiro: (He was always helping father making sure he didn't have to work too much I think somehow he knew that our father's days were numbered and he wanted to make sure he lived his final days in comfort as expected he did the Dance perfectly that year it was so beautiful it felt as if there was a warm breeze behind every movement we couldn't take our eyes off him . . . he's always been the first to protect others it's as if he feels obligated)

Yet another memory reached Tanjiro 10 days before their father succumbed to their illness at night Rimuro suddenly got out of bed Tanjiro noticed his brother's movement and was curious as to what he was doing 

Tanjiro: Brother where are you going

Rimuro: The bear that's been eating people is close by 

Tanjiro: How did you know and what should we do 

Rimuro: . . . I'm going to stop it

Tanjiro: Brother surely you're joking

Rimuro looked at Tanjiro with a face that made it clear he was not

They walked far past the bells set up to let them know when the bear approached 

Tanjiro: We're a bit far out 

Rimuro: We'll be fine but you can go back if you want

Tanjiro: No I'm fine 

The duo of brothers then saw the bear that towered over them it growled

Tanjiro: (What was I thinking I should've brought an ax with us this bear is taller than both of us combined)

Rimuro: Hey fur-ball

The bear looked toward Rimuro and seemed to gain a certain terror as Rimuro looked back with a glare the bear suddenly began shaking it was as if the role between predator and prey suddenly shifted

It was as if Rimuro was a different person the birds taking refuge in the trees fled the bear was shaking seeming to believe every current breath could be its last even Tanjiro couldn't stop shaking

Rimuro: You're still here fine then don't blame me for what happens next

Rimuro picked up a pointy stick on the ground his hand made a swift throw at the bear the stick pierced its head and was left pinned on a tree the bear then fell to the ground a hole was left through the bear's head as it fell to the ground

Tanjiro: (What happened how did he do that it doesn't make sense)

Rimuro: We should let everyone know the bear is gone and maybe we can make use of its meat and fur

Tanjiro: (Thanks to our neighbors helping us make use of it we ate well and were able to keep warm for the rest of the winter he was thought of as a hero but of course, he acted like nothing worth praise happened Brother has always been amazing I wanted to help too but I know that I'm useless in comparison to him but he's always been so kind and let me help even when I could but for as long as I could remember even when we were young children he's always had a scent of guilt even before we became Demon Slayers I've wanted nothing more than to help but even know I'm too weak to be of any use to him so he suffers more . . . no matter what I can't let him suffer alone)

Rimuro ran ahead towards the spot Muzan was

Muzan: So you finally arrived . . . quicker than I expected

Rimuro: It's over and you know it you don't stand a chance against us give up now and I'll make it quick

Muzan: . . . I know

Rimuro: What

Muzan: I knew from the moment I summoned you all that I had no way of defeating all of you all because of you but my true goal in this was achieved

Rimuro: What was that

Muzan smirked

Muzan: Killing that girl you seemed to care about so much 

Rimuro's rage was incontrollable he tightened his grip on his sword it was so bright red it could be mistaken for blood

Rimuro leapt at Muzan with both of his swords

Rimuro: 💣︎♋︎🙵♏︎ ⬧︎◆︎❒︎♏︎ ♒︎♏︎ ⬧︎◆︎♐︎♐︎♏︎❒︎⬧︎ ⧫︎♒︎♏︎ ❍︎□︎⬧︎⧫︎📪︎ 🕆︎●︎⧫︎♓︎❍︎♋︎

But suddenly several flesh walls trapped Rimuro and Muzan with haste stabbed Rimuro with all 10 of his finger nails

Muzan: I know for a fact that I can't defeat the demon slayers as they are now which is why I'll have you do it for me Rimuro Tsugikuni or should I say Rimuru Tempest

Rimuro's eyes widened

Rimuro: H-How do you know that name

Muzan: I've known what you really are ever since Enmu created your perfect dream I learned what my world is to you and I learned there was no way I can beat you but I never wanted you to notice so I followed the path you remembered since then I tried to think of ways to combat you in the meantime so that I could defeat you but I know nothing would've worked and I can't defeat you but I also know you'll be able to take all of my blood YOU WILL BECOME A DEMON AND WIPE OUT THE VERY FORCE YOU TRIED TO PROTECT ALL BECAUSE YOU A GOD LOWERED YOURSELF YOU HAVE EVERYTHING I'VE WANTED PERMANANCE IN POWER NOW YOU WILL FINALLY USE IT TO DESTROY EVERYTHING YOU WORKED FOR ALL BECAUSE YOU GAVE IT UP AND LOWERED YOURSELF TO NOT EVEN THAT OF OUR KIND BUT A MERE HUMAN

A loud strum could be heard Tamayo and Yushiro had taken control of Nakime and the Infinity Castle they forced Muzan to be sent where it was daybreak in a ghost town along with every Demon Slayer to surround him in a perfect formation he couldn't escape but he knew this he let out an awful laugh as he faded to dust

Muzan: I TOLD YOU ALL YOU WOULD BE SLAUGHTERED BUT DID YOU REALLY BEIVE IT WOULD BE BY ME I'VE CHOSEN MY SUCCESOR RATHER THAN TANJIRO THE VERY ANOMALY OF THIS WORLD WILL INHERIT MY WILL

Those were Muzan's final words as he faded away to dust laughing with a smile on his face 

Tanjiro: It can't be Brother a demon

Everyone looked towards Rimuro as he looked at the ground he slowly stood up until he looked upon the crowd with the eyes of a Demon King his aura more terrifying than ever before the plants and small animals of the area all died from the pressure as the one that everyone looked to as a hero of the Demon Slayers stared back with an evil grin on his face in front of the sun completely unfazed

Sanemi: . . . We're so fucked

































































Oh . . . That's not good 

































Yeah no memes this is seriously bad Sanemi may be right . . . Time for a Taisho Era Secret- Oh wait that deal we made if we're lucky it'll be enough probably . . . hopefully . . . possibly . . . yeah don't count on it sorry I can't think of anything else this shocks even me Thanks for Reading and pray for the Demon Slayers they'll need it
