WHAT IF Muzan TURNED Yoriichi Into a Demon? 

Let's not kid ourselves. If Yoriichi became a demon, Muzan himself would become the Upper moon 1.

Yorichi developed 13 forms of sun breathing when he was in his 20s. If he lived for 500 years having faught multiple wars in between. He might have 1000 forms of sun breathing by then. Add the demon capabilities he will get on top.

Yoriichi was 85 years old, blind and seconds away from death and still one shotted the second strongest demon. The moon breathing didn't even come close to sun. Realistically, even with insane plot armor and all Hashiras attacking together they won't land a hit on demon yoriichi unless someone like tanjiro knew sun breathing. Still it won't be enough.

He would have been able to escape Muzan's control and absorb all of his blood by killing him , and later use his sun breathing to develop resistance to the sun. He'd become pretty much invincible and would kill any demon slayer he meets in an instant

Yoriichi would BODY all the hashira if he became a demon 😂 yoriichi already is stronger than Muzan, but you want to give him demon amps and regeneration? Also just like Kokushibo did with moon breathing, yoriichi would develop his sun breathing technique even stronger with his demon form 😂 yoriichi would kill everyone

I feel like yorichi was nerfed like hell in this one

Man I’m surprised that a couple of hashira could beat demon yoriichi even though he could litterly solo muzan all by him self 💀💀💀

Yoriichi as a human could solo all the slayers. Yoriichi as a human with immortality, a blood demon art, flesh nichirin and 500+ years of combat training would one shot all the hashiras at the same time. Wouldn’t be surprised if his BDA was like a sun nuke that can destroy the entire planet in one hit.

The disappointing part is that Yoriichi was nerfed. How can a man who defeated Muzan, be killed by hashiras who had to wait for the sun to defeat Muzan?????🤔🤔

Yorichii would destroy everyone 💀💀

4:30 Muzan is commanding Yoriichi, as Yoriichi said in the start he doesn’t want orders from anyone so a plot twist would be Yoriichi switching sides once again 😊

didnt know yoriichi becoming a demon made him 100x weaker

In simple words , he would have broken the curse of Muzan and then would have developed sun resistance. He would have beat muzan in a insta , devoured him and then he would have trained more and more and have became invincible. After all , tanjiro had been born with enough plot armour to beat demon yoriichi! :-|

Having yorrichi as an antagonist would be much better than having the king of pop . I think it would be interesting after yorrichi taught the kamados the sun breathing, he would go to muzan and become a demon ( he would develop sun recistance and broken the curse) . He would be the one who killed kamado family and tanjiro's major enemy

Yoriichi and Kokushibo duo would hella be terrifying.

I love ur videos so keep up the good work

I actually think muzan would survive because giyu and gyomei were the ones who holded him in place when he transformed into a baby and yorichii would probably visit michikatsu and just kill him

I like the idea of the twins getting Moon Breathing, but let's face it: Yoriichi is simply too strong to defeat by anyone. He would kill Muzan after becoming a demon and use his status as demon king to dismantle the Demon Slayer Corps

i love how he said "back to the main fight" when the rest of the hashira were fighting the demon king muzan

THIS IS SO GOOOOD

Yoriichi as a demon would destroy everyone and anything in less than a second 🤣

Here's my insight: yoriichi and michikatsu are born michikatsu has the same personality like in the manga, but for yoriichi, the exact same except for his personality, he would be selfish and heartless. once yoriichi finds out their dad hates him, yoriichi would train and soon kill his father. the entire town finds out, they plan to kill yoriichi, but to their shock, yoriichi moves faster than their eyes. yoriichi kills everyone, with his bare hands. michikatsu runs away from the house, in fright. for yoriichi, yoriichi would pick up a sword of one of his father's men's, and would train to kill. michikatsu soon finds a sword and a wife, and would train, have kids, and would train his kids, and plus, he would not know about breathing styles as yoriichi inspired michikatsu. and since yoriichi wasn't there to tell michikatsu about that, michikatsu would stick to normal swordsmanship. on the other hand, since yoriichi is selfish and heartless, he would train on his own, and knowing that he is incredibly strong, he creates Sun Breathing, and eventually encounters muzan kibutsuji, and tamayo i guess. yoriichi, with no heart, attacks muzan with the 13th form. muzan is shocked, terrified, and in despair. yoriichi slowly walks to muzan with a evil grin. muzan tries his best to convince yoriichi to become a demon, telling him that it would greatly increase his strength after the transformation. since yoriichi wanted to hear his "final" words, yoriichi hears, and acknowledges this, muzan tells yoriichi how the transformation works. after hearing this, yoriichi accepts the transformation request. muzan splits himself into pieces and builds himself into one piece. muzan pours a huge amount of blood in his hands, and yoriichi moves forward to drink it. tamayo tries to stop yoriichi, but yoriichi cuts her head. muzan, seeing this, afraid, but knowing that yoriichi is stronger than him, doesn't open his mouth or attack yoriichi. as yoriichi drinks the blood, it takes him less than a day to fully transform into a demon, as he is a strong human. and boom, yoriichi is now a demon and muzan feels no anxiety, just confidence. yoriichi does not call muzan "muzan-sama" and muzan angryly asks yoriichi, "why. won't you. call me that? i made you into this strong form," but before muzan could finish, he did not notice how angry yoriichi is from that, so yoriichi cuts muzan's 1800 pieces without muzan realising. yoriichi is now the "demon king" and goes on to slaughtering the demon slayer corps and innocent civilians. since yoriichi is stronger, his speed goes from sub-relativistic, to sub-relativistic+ yoriichi kills the corps, innocent civilians, his friends like sumiyoshi, and meets his brother, michikatsu. michikatsu looks into yoriichi's in disbelief and anger. michikatsu says this: "brother. why. why have you turned into one of them. we were born to kill demons. NOT TO BECOME ONE OF THEM. i cannot call you my brother any longer." yoriichi, annoyed by this, replys this to his brother: "you were not even my brother, i did not need you, or mother. i turned into this, to become stronger. better, and faster. because of this one thing. i don't like the human race. they give me an eyesore. i will live forever." michikatsu crys and yoriichi, in an instant, slices michikatsu, his wife, and children. yoriichi moves on to be the only person remaining in japan. the other countries, are aware of yoriichi's name, but not his appearance, on the other hand, yoriichi, not knowing the other countries, thinks that he is the only person on earth. and moves on to live freely. The End.

4:47 Tamayo wouldn't be there because the only reason she was freed was because of yorichi. I also think Tanjiro would've still learned about demons from that guy at the bottom of the mountain, just his family wouldn't have been killed by them.

Imagine turning the strongest demon slayer into a demon but still lose to the demon slayer corps

Pretty sure sun breathing would still be passed down, since tanjiros ancestors met yorrichi before yorrichi fought Muzan, and from there tanjiro would eventually fight yorrichi and either win, lose, or the unlikely option which is joining yorrichi and being a 2nd Sun breathing demon, in which case the slayer corps would definitely fall.

“What if Muzan turn Yorrchi into a demon” Everyone dies

Tanjiro in the backround be like: I am not here, i’m a hallucination

At the end when the Hashiras was holding him and even after that I actually had tears at that moment 😭 Even tho its just a changed story

Lets be real now... If yoriichi became a demon..he would become immune to the sun for which Muzan tries to devour him but yoriichi no diffs and devours him instead... And would solo the ds corps alone no diff...

If Muzan turned Yorichii into a demon. Manga ends immediately, simple as that lol. No point in continuing the story at that point.

Most demon slayers (apart from tokito and tsukikuni) would not know breathing though, as they have to adapt to their own strengths and weaknesses when making a breathing style

Really like ur videos cause it can turn true

If this actually happened, The Main character will be Muichiro Edit: thx for 100 likes 🎉

Yoriichi would dethroned Muzan and would be perpetually unkillable. Considering he wasn't truly human already or at the very least superhuman.

6:31 why would giyuu use 5th form tho? Blessed rain after the drought is usable only in situations like when spider demon mother surrenders and lets the Tanjiro cut his head in s1 ep 16. I HIGHLY doubt demon yoriichi would do this.

I have a few issues. First of all muichiros back story would not change his parents would still die as breathing powers would not save them and his brother rejected the slayer Corps multiple times secondly yurichi would not be defeated so easily and would probably concor the sun like tanjiro, seeing this muzan would study yurichi and then use him to defeat the hole slayer Corp

I refuse to believe demon Yorichii wouldn't obliterate the entire corps, moon breathing or not.

As a human yorrichi would probably win this, as a demon he would immediately speed blitz all of them

The main problem with this that if yoriichi became a demon there is a chance that his brother would be even more jealous and still turn into a demon

Bro I got hella goosebumps watching this

9:38 did anyone notice that Gyomei behind him was Mitsuri crying

Yoriichi as a demon would be literally the demon GOD dkt may be the demon king but yoriichi would be the DEMON GOD

This whole video is more entertaining than the entire manga

Can we all agree the Murichiro and yurichio moon breathing design is really cool

Is no one gonna talk about how good this guys voicing is?

Personally, I don't think Muzan would even go NEAR Yorichi. At best, He'll be like nezuko with heavier fatigue ( or at least needs way more sleep to prevent him from one-shotting the Demon king) at worse, He'll break free imeedietly and will search for a cure/ hunt muzan. My best guess on how Yoriichi would even become one is near being tricked ( like having someone else putting blood inside the tea or other better methods.) or Muzan decides to do what games do it and make a massive wave of demons to where Yorrichi can't fight fight no more ( not sciectfiically possible)

This wouldn't happen mainly because moon breathing wouldn't be as powerful in this story. You see the crescent moons of moon breathing is a blood demon art from kokushibo, And not only that yoriichi was heavily nerfed in this story. His blood demon art if anything would be when a user gets hit by his breath it will fry their nerves causing absolute paralyzation in where they've been struck.

This man is probably the campfire story teller everytime you go camping

a little side note: from what I have heard Kokushibo's Bda is actually the crescents in his breathing techniques. I could be wrong but then the styles wouldn't have any crescents I mean they could, but they wouldn't do anything much I guess because for it to do something like it did in the manga it would have to be his bda because from the facts the breathing styles effects like the dragons and serpents are not actually real, but you can say it as like an illusion. but it doesn't really matter all that much kind of just a fun fact ig

"Yoriichi, you are pathetic for falling for the dark side.." - Said the one who fell to the dark side in the og story

I like this videos on what it stuff so can you please make a one where it moves on notice that never got with still alive and that he did her something maybe

This guy should write a manga😆 Bro it was great✨

I don’t think you guys understand how much this would’ve impacted everything in the DS verse. You guys don’t realize that every single breathing style would be completely different! Remember everything breathing style is derived from sun breathing. So now they’d be every breathing style derived from a derived breathing which would make all of the alternatives much weaker.

The twins won't be able to kill Yoriichi, as Yoriichi is simply faster than them, even Muzan couldn't react to it, as if Yoriichi teleported behind and slashes appear out of thin air, no surprise that Yoriichi could speedblitz Gyomei, Muichiro, Yuchiro and Giyuu. And on the video, "Yoriichi rushes over to the twins to stop", Yoriichi could easily stop them before they could react, and Yoriichi human can already solo vs all hashiras combined negative diff, no big surprise that Yoriichi as demon could one shot them.

you put 2 versions after act 1 at the start of the video, i noticed that (:

No one talking about why kokushibo didn’t just solo daki and her brother douma akaza hentangu and gyokoi before the “big fight” which means no hashira dies

“What if Muzan turned Yoriichi into a demon?” Tanjiro: Hold my beer

Honestly, thats a perfect Muzan impression. really on point!

9:15 yorrichi: canonly nah id win

It’s interesting how even in a situation where tanjiro and nezuko don’t exist, sibling love is still at the core of Demon Slayer

If Yorichii turned into a demon, then it’s a wrap. Not even the entirety of the demon slayer corps jumping him, could defeat him.

I don’t think that Giyu and gyomei would be able to hold him in place,Because yoriichi’s physical strength as a human was INSANE and if he became a demon his physical strength would boost so much so I don’t think gyomei and Giyu would be able to hold him in place but that’s just my opinion 🔥 video anyway.

I see what you’ve done it’s kind of like how gojo being born made the world imbalanced resulting to stronger calamities being made to even out everything

bro imagine that muzan said the time has come my demons tonight we steal the moon!

Yoriichi is way more powerful than muzan Kibutsuji in his human form , after becoming a demon he is the demon king more powerful than DTK, DEMON Yoriichi will become unbeatable

Yorichi would just solo the Demon Slayers

He said including Yorichii so fast lmao Then he did a uh sunflower thrust

time travelor: moves chair The timeline:

If yoriichi turned into a demon he could most likely solo the entire demon slayer corps

short summary: every demon slayer literally stands no chance

Bro, can you make an animated version of the last fight It will blast off

Awesome story

Yorrichi was playing ping pong with Muzan like it was fun for him literally.

He would be unstoppable no one in the world is standing a chance to him only dkt can be a fraction of his power

The voice acting had me dead

Muzans voice is like a michel jackson😂

Honestly, Yoriichi would probably overcome Muzan through strength , and he wouldn’t be able to control him , making Yorriichi The New Demon King.

Sorry to be a nerd but the crescent moons from moon breathing are from Kokushibo's blood demon art, and thus anyone else wouldn't have them including non demon Kokushibo.

In my school vr game if it happened goalius would be recruited to muzon ranks in secret and the demon slayers will have no choice to evacuate amongst the stars and muzon zenbookse sees goalius and yorichii gives a logical reason why he would be kept alive ( yorichii: goalius is the only demon to be immune to the sun rays and had killed countless slayers humans you name it )

idk about you guys, but it looks like im the only one who noticed the beginning typo. "In this version version of the story..." Need to see if theres more ppl who saw that first time they looked at the vid like me

i imagine muzan would be really scared to yoriichi whenever he touches his sword giving muzan flashbacks then steps away as far as possible but they would probably be like a true friend instead of a partner

The only thing I don’t like about this video is how it makes it seem like a demon Yoriichi would just be a stronger Kokushibo which is definitely not how Yoriichi was originally portrayed in the manga. Also, the last part of the video simply would not happen. The only way how those 4 would even stand a chance is if they’re all stronger than Prime Muzan. Yoriichi would one shot all of them before they could even react. Yoriichi would one shot all of them before they could even react. At the same time, this is ignoring the fact that Yoriichi would be much stronger than Muzan and would probably just overpower his will and take the demon king from him.

If yorrichi was a demon bro would overthrow the demon king himself

Wouldn't yoriichi become stronger than muzan himself? He as a human already overpowered muzan. The demon powers and his skills would surely make him a far more superior demon than muzan. Great video btw

10:19 Mitsuri looks hilarious 😂

he would be the new demon lord

Fun fact : tanjiro Had a Something Like a transperant world in the swords Smith Village Arc cuz He could smell the movements of the enemys when fighting versus the yorrichi Type 0 dool

videop idea: what if yourichi and kokoshibo become demons??

in my opinion yoriichi in his demon state could kill muzan in a second and even conquer the sun considering he uses sun breathing his blood demon art would mostly revolve the sun and his regen speed is even faster than muzan and dkt

Yorichii would destroooooyyyyy. Would muzans blood even help his power.

Yoriichi already overpowered all existing characters combined. Yet giving him a demon form is already the end of story, he was limited by his human weakness (aging, disease, endurance etc), now he can kill everything instantly. If he wanted, their will be no more demon slayer nor demon.

Hold up, he made a mistake, Tamayo was only there in the OG story because Yoriichi made Muzan retreat. Yoriichi was the one to help Tamayo, so Tamayo wouldn’t be in this fight, and neither will her poison.

i dont think demon yorichi would die from a single move like that as he is unstopable and can easily use his regeneration to heal in an instant demon yorichi got nerfed alot

Man this seems like my Grandpa narrating his stories lol

Is it just me or when he voices muchiro and his twin he sounds like the guy from the emoji movie

Yoriichi would have challenged Muzan and become demon king. There is no way he would have obeyed someone weaker than him. He was stronger even in human form..

Did someone wonder how the hashiras managed to kill Muzan without the twins and sanemi and Gyomei

"And selfless state" *shows the transparent world*

If Yoriichi had actually become a demon he would’ve killed every demon slayer in about 0.0000001 seconds

Bruh he would become the demon king
