Thank you for answering my previous ask.

I have read your take on main antagonist!Nezuko, and that gave me an idea. What about an AU where Nezuko is the main protagonist instead? Not role swap (or at least Nezuko remains a demon).

How do you think that would effect the plot of KNY and what do you think would Nezuko´s character arc be about?

No problem!

Funnily enough, I have an idea for something similar to what you're asking about. It's more a "Nezuko and Tanjirou Are More Co-Protags" or "Nezuko Got Her Memories and Personality Back (And Maybe Conquered the Sun) Immediately After Her Coma" AU. Basically what it says on the tin, Nezuko's pretty much back to her human self after her little coma(minus the whole demon thing), and is a lot more active as a character.

Everything past the cut is quite long, so be prepared for that!

So, Nezuko being the main main protagonist? Let me brainstorm some ideas. Starting with setup:

Nezuko still becomes a demon, as you said. However, we need to pull some strings to pull Tanjirou away from center stage. Let's say he got injured sometime between the start of Episode 1 and meeting Urokodaki(so either by Muzan or the Temple Demon). Badly enough he can't use a sword(best bet is either a respiratory injury, or some sort of paralysis. Limb loss just makes him a less edgy version of his beta self.), and his new inability to use a weapon/Breathing Style or fight altogether is noted by Giyuu and/or Urokodaki. Therefore, he's barred from training, but he still wants Nezuko to become human again.

After realizing Tanjirou is in no condition to fight demons, but still wants to cure her, Nezuko takes matters into her own hands. Starting with a coma. However, it's shorter than canon(let's go with 6 months to a year) because she pushes herself to her absolute limit to pretty much speedrun her season 1-3 development(making herself resistant to her demonic instincts and sun-proofing herself are her main priorities). When she wakes up, she gives everyone a heart attack by walking outside.

After everyone calms down when Nezuko doesn't burn, she asks to be trained. Urokodaki is hesitant, but can tell Nezuko has a very strong resolve. She wants to help her brother attain his goal of turning her back into a human, and also seeks revenge on Kibutsuji. So he agrees to train her. It's difficult to train a demon in a Breath Style, but Nezuko's will and determination makes it easier for her to perfect her moves.

Tanjirou helps where he can, maybe even remembering the Hinokami Kagura sooner and teaching it to Nezuko when he does. But he's also a worried big brother, despite Nezuko's assurances that she'll be okay. He definitely tried to take up a sword at some point, but ended up getting a hefty scolding from both Urokodaki and Nezuko when they found him.

Starting from there, what effects would there be on the story?

Demons are hella confused. Who is this girl? Why does she give off the presence of a demon, yet wield one of their blades? And if she is a demon, which some doubt she is, how dare she turn on her own kind and help those who would sooner kill her than work in tandem with her? (this is especially fun on Mount Fujikasane, during Final Selection ÒwÓ)

Muzan takes an earlier interest in Nezuko when they run into each other in Asakusa, perhaps even sending one of the Twelve Kizuki after her. Luckily, he still doesn't realize she's conquered the sun until the Swordsmith's Village, so she's just considered a rogue demon until then.

Zenitsu is far less forward with his affections, and is force fed respect women juice. His and Nezuko's relationship is a lot more mutual and starts with friendship. Inosuke tries to behead Nezuko in the Tsuzumi Mansion, but they sort it out eventually and Nezuko becomes Inosuke's favourite minion/sparring partner.

The mental breakdowns that will occur during the Hashira Meeting. A good demon? And she can walk in the sun?! Perhaps the sky is falling down, someone check!!!

Nezuko not only fighting the demons, but desperately trying to avoid capture by them. If they get her back to Muzan, it's all over.

She's also a fair bit more powerful, as I imagine her cells would start photosynthesizing after she conquers the sun. So Nezuko can gain plenty of energy from sunlight, enough to use her full demon form and Blood Demon Art for extended periods of time without a lack of usable energy making her hunger a problem. Where she could beat up Daki easily, and had a struggle against Hantengu's emotion clones in canon, I'd say she's on Douma's level (maybe Kokushibou's if she really pushes it) at her peak in this AU.

Rengoku probably won't die. Assuming Akaza gets sent to the Mugen Train. If he doesn't, that may be a different story.

While Tanjirou doesn't fight, he still keeps running into demons. Or rather, demons keep coming to him. Poor guy can't catch a break. Muzan found out about Tanjirou somehow, and thought he could either turn Tanjirou and get the same results he wanted with Nezuko, or that he could use Tanjirou as part of a trap and kill the eldest living Kamado once Muzan had Nezuko. At first, Urokodaki is protecting Tanjirou from any demons that show up. Then Urokodaki sends word to Giyuu at some point that they need to transport Tanjirou to a more secure location because demons keep knocking down his damn door looking for the poor kid and Urokodaki's too old for this BS!

As a result, Tanjirou is brought either to headquarters or the Butterfly Mansion, as both locations are top secret and surrounded by anti-demon security measures.

Nezuko might be influenced by Genya to start eating demons. She sees him chomp a tree, and decides she might as well do the same because why tf not? Demons are surprisingly nutritious. She only has a minor crisis while wondering if the humans the demons have already count for her human consumption count.

Eventually, the Infinity Castle Arc happens. Nezuko ends up against Kokushibou with Sanemi, Gyomei, and Muichirou. Genya gets sent to battle Akaza with Giyuu and Rengoku. Both battles would be hard, but they'd ultimately emerge victorious, with a couple close calls on both ends. Not sure if Mui survives, but Genya sure does!

Most of the final battle is Muzan trying to capture and absorb Nezuko, and Nezuko is using his flesh as kindling. The majority of the human Demon Slayers' injuries are far less severe thanks to Nezuko's BDA burning out Muzan's poison. And at some point, she gets the antidote, which ups the ante. She needs to finish Muzan before she turns back into a human and loses her demonic strength, but she can't get too close lest she be absorbed and all her hard work be for nothing.

As the sun rises, Nezuko become a human again just when Muzan goes to devour her. Her final attack costs her an arm, but she survives and wakes up after the battle to her teary-eyed big brother and the friends she made on her journey surrounding her.

Nezuko's arc would mostly be learning not to rely solely on the strength and power she received as a demon, as it will only last so long and will go away once she's human again. While she has no intention of taking the antidote until the final battle, it's still something she needs to remember.

She also learns to lean on others for help in this quest to restore her humanity. Whether it's asking others to help her get blood, or stepping back while others take the fight, she doesn't have to do everything on her own. Even if she's a demon, and can handle a lot more than any human, she can still let the humans handle it.

And lastly, dealing with the guilt and self-hatred she's bound to experience. Her mother and younger siblings were killed, and Tanjirou got injured, all while she couldn't do anything. As a result, in wanting to do more to protect her last living sibling and the new family she's built with the Kamaboko Squad, Nezuko overworks herself to a point that would kill her if she was human. Someone(probably Kanao, Shinobu, Mitsuri, or Muichirou) eventually has a talk with her about what she's doing, and helps her work through her trauma.

Those are all the ideas that I managed to spitball off the top of my noggin, and I am open to more.

Lore dump on me, boi! Give me all them demon details!

If you’re talking about the demon Inotan au… ofc >:)

So in previous asks (that you can hopefully find through the demon inotan au tag) I talked about Inosuke essentially being Douma’s pet dog which is why he gets to be in close proximity to the other upper rank demons and Muzan. Obviously other demons can come across them and such, but only Inosuke can know about the fortress and learn about them personally because they’ve all written him off as Douma’s stupid dog (also Douma gossips. Like a lot. So even if Inosuke didn’t see them for himself, he’d know a lot about them bc Douma can’t shut up). Inosuke is ambitious and wants to join the higher ranks but doesn’t know Douma has been purposefully holding him back this entire time so he can keep control over him.

Inosuke was also loaned out, essentially. He helped Daki and Gyutaro the most because they had close ties to Douma, so Inosuke was exposed to their power and what it takes to join their ranks very directly. When Daki and Gyutaro die, Muzan appoints Inosuke in their place against Douma’s wishes. He’s already at the strength of Enmu at that point, and is the last equivalent they have to a lower rank anymore. Inosuke is initially thrilled, but it’s not as exciting as he thought. He’s almost immediately weighed down by his guilt of betraying Tanjiro by accepting the position, and he knows the pressure to hunt and kill Tanjiro will be worse than ever now.

He completely reevaluates his position when he gets word that Tanjiro has conquered the sun, and now Muzan wants him personally. Inosuke knows how to find Tanjiro, and knows that if Muzan ever finds that out, it’ll be over. He decides to find Tanjiro himself and explain, try to make sense of what’s going on and possibly leave Tanjiro forever.

When he finds him, Tanjiro and his group are traveling home from the Swordsmith village battle in the day time. Inosuke is hidden in the trees and Tanjiro comes up to him, bathed in the full sunlight, alive. He tries to come into the shadows, but Inosuke demands he stays there, suddenly ashamed. Tanjiro hesitates, then starts to talk about a suspicion he had that Muzan would start replacing the Upper Moons they’ve killed. Inosuke admits that he has been, and finally gets close enough for Tanjiro to see the rankings marked in his eyes.

Tanjiro is… heartbroken, but hides it behind a tired smile. He says something along the lines of “I see you’ve chosen your side”, and Inosuke snaps back, “you knew this was my mission!” To which Tanjiro replies, “I did. I was just… I was hoping you’d choose me.”

It pushes Inosuke to finally break. He tells Tanjiro he was going to, he wanted to choose him more than anything before this happened, and he doesn’t want this title anymore. He tells him that things have changed, he wants to be with Tanjiro, wants to be human again! And Tanjiro tells him he still can! The marks mean nothing if he doesn’t want them, he can still leave and they can work it out together. Inosuke thinks it’s impossible, but Tanjiro insists that he’s living proof Muzan doesn’t control them if they fight hard enough.

Inosuke considers this… and promises Tanjiro he’ll be back, but there’s one last thing he has to do. He goes back to Douma, and confronts him for the last time.

That’s… all the energy I have to write about this now! Lmao but hey, I told you guys I have a planned ending in mind!

[shakes tin can] spare demon biology headcanons please? I'd love to hear about any and all demonic biology thoughts you have !!

Hehe, I hope you are ready for a mild essay

(Also prefacing this with the disclaimer that I don't know dick about science and haven't studied science since my undergrad degree and even then I only really paid attention when I got to cut shit up or blow shit up so this is definitely not based in any actual understanding of how mutations or evolution or viral infections work, Lee, if you read this, I'm so sorry bestie in science it's probably very inaccurate lmao but anyways)

So!!! We know that the demonic infection/mutation stemmed from experimental medical procedures used on Muzan based on the blue spider lily. While of course, demons are largely supernatural beings, I personally love the idea that there's a lot of scientific backing with how they function, develop, and evolve. Which, considering how demons were first created, and that a drug was created to return them to being human, I feel like that's a fair assumption to make. Personally, I like the idea that it's similar to a blood-born virus, and that there are various mutations of that virus.

Specifically, the virus continually mutates in an effort to survive and preserve itself (which viruses tend to do in any scenario). But the demonic viral mutation was originally created as a way to save Muzan's life because he had a terminal illness. It cured him of his illness, and made him virtually immortal, which is where the more supernatural elements come into play, but I'm not gonna focus on that bit right now.

Muzan (and nearly every demon we saw) had a near feral desperation to stay alive. The only demons who didn't were the ones who were so miserable they were suicidal, at which point I don't their their instincts were strong enough to drive them to survive (like the mother spider demon, and eventually Akaza). I like the idea that the virus biologically drives the host to preserve itself. Of course, these demons wanted to live anyways, but upon their impending deaths a lot of them were driven to attempt some intense things to try and survive (everything Muzan did towards the end of the final battle, Hantengu in the Swordsmith Village, even Akaza ripping his own arms off during the fight with Rengoku). I just think it's a fun little idea that being a demon forces them to do anything necessary to survive

Which then leads to further mutations of the virus that leads to the host being even more difficult to kill, which for demons, meant surviving decapitation with nichirin blades, or conquering the sun (and with conquering the sun, surviving a nichirin blade would then be simple), and the only four demons we ever saw accomplish any of these things were Nezuko, who conquered the sun, (and Tamayo even said that her blood was different after that), Tanjiro, who also conquered the sun, and then Muzan and Akaza, who survived decapitation. The mutations that allowed these things to happen led to the further survival of demons in general.

But that's just some jargon about the infection itself! Fun, but I personally am way more interested in the mental links and existence of what could be considered a hive mind amongst demons.

We know Muzan has a link between all the demons under his command. He can speak with them, and via Nakime and her Blood Demon Art, summon them, and then of course, the Name Curse. Canon is admittedly pretty flippant with how these connections function so I tend to take a lot of leeway with them. Namely, the concept of Demon Kings in general.

I think Demon Kings are a natural hierarchy system that demons instinctually default to (like a queen bee in charge of a hive or something similar). A Demon King is the most dominant presence in a hive mind, with the most amount of control. This was what Muzan was, and then was what Tanjiro became with his transformation. Demons within the hive mind will naturally default to the King, and another King will not evolve unless the demon in question breaks the blood links with their King, and then does not immediately form another blood link with an already existing King. Due to this, I like the idea that Tamayo would technically be considered a Demon King because not only did she break free from Muzan, but she also created Yushiro, who then was a part of her hive mind. Nezuko also had the potential to be a King, had she ever turned anyone or formed blood links with other demons who didn't have a King.

These are the main thoughts I have on how the general virus functions along with future mutations, but a few smaller, general headcanons of mine regarding demonic biology would be

They have to eat so much and deal with such an intense hunger due to the sheer amount of nutrients they require for their accelerated healing abilities and Blood Demon Arts. Both of these things burn so much energy, it leaves them starving more often than not

Demons can form intensive blood links with each other and the strong mental/emotional connection can aid with survival. Like Gyutaro and Daki having to be decapitated at the same time. Essentially, they could keep the other alive through sheer force of will so long as the other was physically sound enough

Again, canon is pretty flippant and has a few contradictions on how demon turnings work, but I like the idea that any demon can initiate a transformation. However, the further out from a King you go, the more dangerous a transformation is and the more likely it is to result in death. (Think of it generation-wise, a King and those turned directly by a King have the strongest versions of the virus. The further out you go, the less intense it is. With a weaker version of the virus, a host is more likely to die during a violent transformation, rather than have a successful one)

In a similar vein, the further out from a King you venture, the less human reasoning and intelligence a demon is likely to have. Those that are little more than wild animals were transformed with weaker versions of the virus

These are the big headcanons I have! There's a few smaller ones regarding specific instincts and how/why exactly demons end up with particular physical changes, as well as wisteria and its affects, but I feel like those are vaguely different topic so Eh

But I hope you enjoy my demon rambling that almost certainly doesn't make sense upon actual examination haha. I just think it's very fun

#this is kinda all over the place i hope it's at least somewhat coherent haha #kimetsu no yaiba #i have no real idea how to tag this #asks #kaz rambles
