What If Demons Could Not Regenerate in Demon Slayer 

Hi can I please get pinned I’m am ur biggest fan 📌

If they could not heal, then Nezuko would have to be really careful.

Tengen would’ve retired either way. In the manga it mentions that he was going to retire after his mission in the entertainment district. With his injuries it just gave even more reason for him to do it.

Lol tanjiro's mom casually using blue spider lily in her soup every day and muzan literally spent his life finding it 😂😂😂😂😂😂😂😂

If this happened, Demon Slayer wouldnt be an anime as we saw muzan into pieces running away from yorichii

every demon would be dead since muzan would be killed by yoriichi 500 years ago💀

If there was no regeneration, half the story wouldn’t be hard for demon slayers

One crucial detail you missed: If the Ubuyashiki mansion exploded in the same way, then Muzan would be dead, because he couldn’t regenerate his injuries. If that didn’t kill him, then the final fight would have been a piece of cake for the slayers (Tengen would have retired anyways, but Rengoku would have been there. Mitsuri and Obanai wouldn’t have gotten badly injured either) as the hashira’s (besides those in Kokushibo’s fight) would be basically unharmed. A lot more Hashira would have survived because of how weakened (or dead) Muzan would be. Also, don’t forget Tamayo’s poison.

Something you forgot is that Genya couldn't regenerate either, so he would die against Hantengu. But he didn't do anything against Kokushibo, so the story would stay the same.

The reason the demons are so freaking powerful is because of their regeneration, their regeneration allows them to recover from fights and train for long periods of time because they don't need to take a break, they can just continue because their regeneration means their blood travels the body faster and take in more oxygen. If they can't regenerate fast they would be extremely weak, they would be humans with better strength, speed, stamina but not enough to regenerate fast.

Really awesome concept! I'd be curious about a few things though as I don't think Nezuko would die from Hantengu since they don't use Nichirin swords. They don't die because they're cut, they die because the swords used disintegrate whatever's severed like they're in sunlight. Urukodaki hinted you could kill a demon if you smash their head in but I'm skeptical of that since the demon in Muichiro's flashback didn't vanish until the sunlight showed up despite having a boulder on his face. The same rule would apply to Daki if Nezuko's the one to beat her because she'd have to be cut by a Nichirin sword. Their head could still survive on its own if it's not decapitated by a Nichirin blade, they'd just have to control their body to take it and run sort of like Rui did when he severed his own head. I'd picture the Rui fight not changing much, he'd just hang his severed head from a tree watching his body to control it to fight until Giyu shows up and cuts his entire head like Muichiro does to Gyokko. ALSO, I'd find it really interesting if we had an EXTRA Hashira here: Kanae Shinobu. (Well, only 9 are allowed at a time so Kocho would be Kinoe rank) We never saw her fight with Doma, but she died the same way Rengoku did, holding off the upper rank solo until they had to flee because of the sunlight which means she likely gave him a run for his money in the fight so put Kanae and Kocho together against Doma before Inosuke and Kanao arrive to help.

"Would rengoku escape the doughnut treatment"caught me off gaurd 💀💀💀

The story would stop 300+ years before the main storyline... Yoriichi vs muzan

No , Nezuko will survive due to her conquering the sun and regeneration has nothing to do with her sun resistance.

I’d rather not have Nezuko meet his maker personally. Tanjiro’s lost enough loved ones, as it is. I think she might survive given that Hantengu’s clones probably couldn’t regenerate.

10:06 Muichiro initially sliced hantengu’s head off and heantengu regenerated and split into three clones, so if he wasn’t able to regenerate, they would have easily defeated upper rank 4 & 5 within few minutes and sunstaining absolutely 0 injuries, also one more thing is that Gyomei smashed muzan’s head and decapitated him so Muzan wouldn’t be able to regenerate and everything would end without the infinity castle arc, I guess we could say a timeline where demons can’t regenerate is just not possible😅

I feel like the demons will be more careful with demon slayers.

Keep in mind if demons couldn't rapidly regenerate to a degree, you'd be dealing with very different demon culture, fighting styles, and its highly likely Muzon would have required Kokushibo to teach every other demon who made it to moon breathing. I also feel like you under estimate how much the dynamics with Daki and her brother would change. 1. Without hyper regeneration her brother isn't likely living in her, but just skulking about in shadows. 2. With her brother unable to hide in her the secret tunnel system is therefore likely far better developed and trapped. 3. This would just about entirely change how willing Daki is to stay in a fight once her brother has to intervene, since no regeneration means they're even more dependent on their linked life, and thus she'd be even more aware her role then is to run and hide, while the semi-independent part of her sash hides in waiting to pull her brother's broken body to safety if he loses. 4. With being less able to rely on her brother to bail her out, chances are high Daki is forced to put more effort into being a better combatant. --------------------------- Not sure about this Nezuko arc, but rather the first battle where she got significantly injured would likely prompt her to request Lady Tamayo do to her whatever let them survive without eating humans. This is also honestly one of the odd things about the main timeline, I never understood as well, since there is very little wrong or that harmful with a demon taking a non-damaging amount of blood. You also forgot the eat demons as they go alternative. Thus we're potentially dealing with a stronger Nezuko, since this version wouldn't have been able to starve herself and hibernate. Also lets face it if demons can't hyper regenerate Muzon is likely far more open to the idea of sending groups of demons on important missions and destroying the Swordsmith Village would be a far higher priority, to get rid of the weapons that are kryptonite to them. However learning of her demon art Muzon is far more likely to order Nezuko taken alive in the hope she can learn to heal demons as well, thus I'd potentially see this arc ending not with her death but Nezuko surrendering herself for her brother and a very small group of survivors being let go. Basically the Swordsmith Arc would be entirely rewritten to one where the slayers have no chance of victory, but instead have to focus on saving enough people the swordsmith art isn't lost with the village. -------- Also wow this video's comments are filled with people who didn't pay attention and just posted but Yuroichi kills him.

In the fight between kokushibou and the hashira's genya swallowed a piece of kokushibou broken sword an received a massive amount of boost in his blood demon art which allowed him to hold kokushibou to for seconds in that moment gyomi cuts kokushibo's head but in this story that never happened cause demon can't regenerate neither can genya who uses the power of demons so while trying to convince muichiro to become a demon kokushibou spots genya an imidietly cuts genya in half eventually killing him so without his help other hashira's stand no chance against kokushibou so in the final fight they not only have to fight muzan but also kokushibou so I don't think they can defeat both at the same time

What if Akaza never showed up to the Mugen Train?

he forgot that after ubuyashiki's explosion, tamayo immobilized muzan and gyomei easily destroy muzan head

Well they have to be a lot more cautious, cause Akaza would’ve been destroyed without his regeneration

If they didn’t have regeneration , then Shinobu would solo uppermoons 2-6 .

I think even without healing kokushibo would at least manage to kill 2 hashiras cause of his speed and moon breathing

You are by far my favorite what if content creator so sorry if my nitpicks are mean. 1. In the fight between rengoku and akaza, he would still die because if akaza is being more careful (as mentioned in the beginning) he would use all of his forms that are much stronger then any of the ones he used against rengoku, meaning he would def kill rengoku one way or another. 2. In the fight between kokushibo and everyone else, he ended up dying because he held back for a while because he did not want to ruin the fight and immediately kill them. However, since he is also being more cautious, he would hold nothing back at all and they would all end up dying. Even if we don’t include the cautious factor, kokushibo was not very reliant on his regeneration for a while, and since he is stronger everywhere else he would still kill them. (Also another comment brought this up: genya would die from no regeneration so they would be lacking him which makes it even harder).

If this was the case, then Donut wouldn't be a Donut anymore

After Muzan split,Yoriichi destroyed so many pieces there was enought left only to rebuilt a head! If anyone with titan shifter healing could survive that....let's just say Attack on titan would have gone differently.

Wait in the end of the hashira training arc, Gyomei actually destroys Muzan's head and Muzan isnt able to regenerate, does that mean he has to fight headless or is he just dead?

That would make things a lot easier for the heroes, would it?

People need to realize, tengen didn’t retire because of his hand, he retired because of the promise of hinatsuru. In the flash back it said, “when we defeat an upper rank, let’s live as normal people.” And tengen took that chance.

what if demons fought more as a team because of lack of instant regeneration? Like having kyogai nakime Zohakuten fight together...it would be over.

you got 2 things wrong if nezuko were to die in the village arc then genya would too and they wont die cuz hantengu will be in his fully powered form from the get go as well as nezuko would also not be so reckless and try to avoid slashes or injuries

If they can't regenerate instantly. Then everyone would be doing "American Breathing" First Form: 🔫 of the clssroom

5:22 its not football nezuko no

the thing is that nezuko has her blood demon art which regenerates the ones arround her and herself, so that means that nezuko wont have problems healing

If demon can’t heal, then Mitsuri would cook Hantengu.

6:45 you forgot that the demon's skin or durability is way better now bruh

1:29 why did I laugh😂

before watch the video my opinion is. okay we can't regenerate let's learn the breathing style.

If demons could not regenerate then Kanae would be alive

Since demons have much stronger skin they are eventually much stronger than in the orginal story.

*You are now a smart anime watcher!*

If demons couldn't heal than muzaz would have died in the fight with yorichhi the goat

0:45 i saw the [as] reference

Rengoku still dies, you said it yourself, the demons are more cautious. Akaza was just playing with him, so akaza is now buffed even though he was so strong he could play with rengoku.

i hope you do know that yoriichi had no intension of killing kokushibo. he still loved him. and he didnt even aim for his neck!

Muzan will never get the Blue spider lily now,Because its a dead stew >:) XD.

Bro if they can’t regenerate the show would’ve been like 13 episodes 😂😂

Ngl if shinobu lands one hit on douma he is dead since he cant heal the poision which is insane to think about since she would probally become the strongest demon slayer in this timeline

If Muzan could not regenerate then he would have died with the explosion that ubuyashiki made

Hello yorichi, bye bye Michael jackson.

smth u didnt think about is that nezuku can regenerate just by sleeping

In this story demons can't regenerating so hatengu can't split into the power full form

If tanjiro is immune to the sun, why isn’t nezuko? They ate the same foods

You do realize that douma should've been ducking dead since he got his guts slice out by kanao or inouske idk

If demons couldn’t regenerate shinobu would instantly be one of the stronger hashiras because of her speed and poison

At least 2 of the 9 hashiras died instead of 6-9 of them dying

My one question id how Tanjiro almost defied the laws of demon slayer physics by almost killing Rui with out A BLADE ON HIS SWORD Edit: doesn’t muzan have five brains? I have proof he shouldn’t have five brains in the original time line why didn’t he think of bringing nezuko to infinity castle to consume her?

Nezuko would actually be the only demon able to regenerate. Her Blood Demon Art can regenerate her.

wouldn’t the whole story end when yorichii found muzan and just soloed him

Bro really forgot an important step FIRST WHEN MUZAN KILLED UBAYASHIKI AND HE GOT TRAPPED BY THE DEMON ART SPIKES AND POSIONED BY LADY TAMAYO AND TAMAYO TOLD GYOMEI NOW AND HE BEHEADED HIM

What if demon slayers had cursed energy

Yorich kills Muzan then, thus demon slayer story doesn't take place

Personally if I was demon tanjiro I would of consumed akaza to gain more power and then when I go to fight muzan I would have more of an advantage

Bro, your bugging kokushibo would have died because yorichi slit his throat before dying, and why don't demons die from blood loss in this video.

muzan can take a bite of flesh of whatever he eats, a different theory would be that he hit tanjiro and thus conquer the sun by bitting him. only works if this quantity of blood is enough to gain his power

akaza the second he sees rengoku with no hesitation would one shot him and tanjiro and everyone else lol

Akaza could easily have killed Rengoku, especially with the amp given in this version to stats. He may even have killed Tanjiro there considering the lack of serious injuries.

Nezuko sleeps instead of eating humans so just another 2 years

if demon did not regenerate then series not be that long bcoz muza. Was killed by yorrichi a back ago 😂😂😂

The red blade plus sun breathing=satan becoming their whole family

Zenitsu would extra lock in after finding out about Nezuko’s death

Your forgetting something. Tanjiro cant be a demon in your circumstances since he will be a demon under controlled by muzan. Even tho nezuko was a good demon she became good because muzan didnt have intrest on her and thought she was dead so she was not given the curse and vow. In tanjiro's case for an uppermoon to turn humans into demons. They must ask muzan for his blood via telepathy so muzan will know about tanjiros wereabouts making him under his control

Well If this happened a long time ago Muzan wouldn’t have been able to survive yorichi so yeah they do need regenaration

If they could not heal they would be still powerful I mean look at how fast demons can be

Nezuko recovers with sleep bro

Simple, there will no demons as Muzan would have been cut to 1500 pieces by yoriichi centuries back

i feel like tanjiro demon form could pose a weak threat to yoriichi but tanjiro demon form defeats muzan

Domas face after antaganizing akaza and akaza punches him🤯

They have to have regeneration because what’s the point of being a demon that will easily die

The demon stat increase doesn't make sense. Harder skin. It would be thiccer and heavier. Speed would decrease by 0.01% Akaza's strikes would be bit more stronger because he uses his fists. Demon slayers would be also stronger if the demons were

AT FIRST MUZAW WOULD BE DED CUZ HE SPLITED INTO 1.8K PEICES IN WIGHT WITH YORICHI

9:10 in this scenario tanjiro wouldn’t accompany tengen because why would two hashiras go for a normal mission Btw I called this normal because they don’t know the fact that there is a upper moon just chilling there lol

Gyokko would be dead because gyutaro is actually stronger than gyokko leaving tengen to fight the last battle with most likley major injuries

Thats like saying what if demon slayers couldn't have blades

gyutaro would kill tanjiro, since tanjiro was trying his hardest to cut his neck and now gyutaro even more powerful so tanjiro wouldn't be able to cut his head, similarly when zenitsu tries cutting daki's head, he wouldn't be able to do it

I like this video when 20 people like this masterpiece

If they could not heal , then how genya will be alive when kokushibo cut his head ?

muzan will prob make a potion to heal rapidly

If demons couldn’t regenerate demon slayer would hardly be a thing for 1 reason Demons being able to live for so long would be due to the fact that they have crazy regeneration that eliminates old aging, so muzan would’ve be guaranteed to die either way He would’ve had the great strength that he had but dying to old age isn’t something no one can run from, and if he didn’t die of old age he would’ve died from yorichii as sense we all know the cut that managed to hit muzan were so strong they left scars muzan would’ve died without ever having the chance to use his demon art to split into pieces and get away And without muzan demon slayer wouldn’t have been a thing due to muzan being the only one who can instantly transform and allows a person to become demon besides tamayo but we all know if she had ill intentions she would’ve also been killed by yorichii leading to her never having the 200 years to turn that one guy into a demon (forgot his name, im sorry) Anyways my point is if demons couldn’t regenerate then demons wouldn’t exist.

Can you make what if tanjiro had moon breathing

pov when akaza punched douma in s3..

then muzan would be a normal human bc the doctor will know demons cant heal

Without regen im sure any hashira can beat one of the 12 kizuki except Kokushibo or Douma

If they could not heal Muzan is already dead 💀....Yoriichi

If they couldn’t heal doma would’ve been fighting shinobu with half and face

7:52 if akaza would be even faster and more stronger than before that means renogoku will have absolutely no chance

If demons had no regen they'd train to dodge

If they couldn't regenerate then that means rengoku would have survived 😭

Yushiro will die to susamaru his head was blown off
