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.

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.

[@Chris-ls1ub]

he trapped kokushibo in a tree demon art thing, suspending him in place for the pillars to rush, and ultimately lead to kokushibo seeing his reflection and letting himself die. without genya, muichiro, sanemi, and himejima lose.

[@hylianhero1921]

Genya was the sole reason they won that fight. Without Genya, Sanemi and Gyomei die, pitting Kokushibo and 2nd Drug Muzan against the heavily injured hashira, which mean they loose

Yes, if rui can't part his head by himself because he'll die then muzan definitely is dead

[@anvos658]

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.

[@Night-mince0]

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.

[@joshuafoote5144]

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.

[@firewater3957]

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

[@Not_rzn55555]

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

[@TheRealSharkyIsNowHere]

Wasn’t that funny gang

[@DarkCape64]

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.

[@Meed2009]

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.

[@marpajaypangan]

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

[@taunouugwanga1245]

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

[@Night-mince0]

She was severely injured by the clones (although they wouldn’t be there because of Hantengu being killed and the clones not being able to appear.)

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😅

[@Night-mince0]

Exactly. And The mansion blew up, and Muzan’s injuries wouldn’t be regenerateable.

[@anvos658]

I think we have to accept unique powers like the siblings linked life and Heantengu's cloning still work as a way around the regeneration rule.

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

[@C0SMO719]

[@TheOriginalLurker]

@@mich_69 The demons can’t immediately kill the hashiras like that 💀. (Other than Base mui’s case) Last time I checked Shinobu blitzed him multiple times . You can say Doma was toying around. But the last time with her centipede dance , it’s clear Shinobu out paced and blitzed Doma and nailed him to the ceiling . Besides a single stab to the vital organ or poisonous slice is gonna be enough to kill Doma 💀(he was puking blood and on the floor when he first got stabbed) Doesn’t change the fact that Shinobu still would solo. She’s perception blitzing the upper moons 4-6 with ease no diff . If demons getting more serious won’t matter much other than some cases like Tengen and Gyutaro and base Muichiro and Gyokko (not counted marked mui). Base Mitsuri would have manhandled upper 4. Rengoku would have successfully permanently damaged Akaza (when Akaza had to rip of his hands) . Tanjiro and marked Giyus tag team would be a lot for Akaza . Only Kokushibu’s the one who would still solo everyone.

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?

[@anvos658]

Honestly this is likely a case where pulling the slayers into the Infinity Castle isn't part of the plan but rather Nakime sending demons to the slayers and when Muzon or a Moon is critically injured recall them to the Infinity Castle.

[@Albroofficial]

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).

[@om9959]

Akaza will die against any marked hashira.Kokushibo will get his shit rocked by gyomei considering koku cannot regenerate his sword.

[@KennyShin-l7p]

that's false tanjiro and marked giyu barely killed akaza but in the end akaza killed himself in the infinity castle war

[@Eeropro203]

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

[@anvos658]

Honestly in general I think he massively underutilized Kokushibo in this one, since no regeneration means demons learning proper combat and trying to teach them breathing techniques would have far more emphasis.

[@roselynabrenalin6991]

I like this video when 20 people like this masterpiece

[@KNY_Lover13]

So Nezuko dying would require hantengu to release Sekido, Urogi, Karaku, and Aizetsu through splitting then regenerating an entire body or head to release the next pair of demons. Wether you count that as regeneration or not is up to you, however I would count that as regeneration

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

[@KiKi_Vvyx]

But a thought Nezuko’s head got cut off by daki+ daki’s belt split her to multiple pieces. Without regenerating Nezuko with that much body parts split alive she probably wouldn’t have survived. Also cutting off a demons head kills them right? So I think Nezuko would be dead

[@KnightRider-mq4wm]

i think not since demons are still technically immortal that would mean they still need their heads cut off by nichirin blades or their bodies burned by the sun nezuko would have conquered the sun early and there probably wouldnt be a swordsmansmith village arc. since nezuko could still heal up from her injuries

[@anvos658]

Even without regeneration a demon would live through being eviscerated, unless they were ate by another demon, exposed to the sun, or cut by a nichirin weapon. The issue however is that would be a KO, which means she wouldn't be able to save Tengen and anybody else the brother stabbed in the alternate fight. The swordsmith arc is also hard to say if Nezuko would be able to even be there without a time delay, since it would depend whether or not Shinobu and the medical core stitching her pieces back together would make it easier to heal.

[@Halo_wood]

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.
