I saw swap!Tanjirou and Genya have moon earings. Did Michikatsu take them in similer to how Tamayo did with Yushiro? If he did, what are their relationships like?

You have no idea how happy I am that you noticed them both sharing the moon earrings!

Let me introduce you guys to the worst friend group ever made!

Not a SINGLE person here is sane or normal. This ended up being much longer and lore heavy so I made a key, just in case anyone only wanted lore about certain characters

Michikatsu lore has his name is highlighted pink

Genya Lore has his name highlighted purple

Lord Founder Inosuke Lore has his name highlighted green.

Tanjirou Lore has his name highlighted red.

Kaigaku Lore has his name highlighted blue.

There will be overlap! Enjoy!

Genya was picked up by Michikatsu when he was sixteen about a hundred years before the Taisho era. Michikatsu used to train demon apprentices in the hopes that one day he could find someone capable of defeating Muzan, but every one of them besides Genya either died or betrayed Michikatsu, and he’s since sworn off the practice of turning anyone into a demon.

Genya is extremely loyal to Michikatsu, and this is mostly due to Genya believing that Michikatsu is the only one who can train him to achieve his one life goal; killing the Upper Moon Three, his older brother.

Tanjirou does not start out as Michikatsu’s apprentice; in fact the first of Tanjirou’s friends is actually Lord Founder Inosuke! They meet a couple months after Tanjirou’s demonization and due to some unfortunate circumstances, Inosuke ends up losing his cult and gaining a massive grudge against both the demon slayer corps and Douma The Ice Hashira.

(Note; Inosuke is NOT a demon, and I will be drawing up a full backstory on him when I get the chance)

Inosuke believes Tanjirou to be a forest spirit rather than a demon, and believes himself to be a literal god, and although when he and Tanjirou are alone, Inosuke acts very much like the loud, boisterous boy we’re familiar with, he acts almost unrecognizable when meeting other humans, presenting himself as a kind, considerate sage with a serene smile… a lot like cannon Douma…

Genya comes in after the corps catches up to Tanjirou and Inosuke at Mount Natagumo, where the two became entangled with both Rui and the corps.

Tanjirou and Inosuke are taken in by Michikatsu after escaping with Genya, as Michikatsu sees in Tanjirou a demon who could possibly be capable of defeating Muzan.

Michikatsu has mixed emotions towards Tanjirou, because it’s difficult for him to trust any demon, especially one that seems so pure and ‘human’. The matter is not helped by the fact that Tanjirou is able to perform sun breathing. Even after so many centuries, even after defecting, Michikatsu’s insecurities regarding Yoriichi run deep.

Inosuke believes Michikatsu to be a demigod, and constantly pesters him about training as well as insisting that Michikatsu should become his vice leader when he reestablishes his cult. If Michikatsu could go bald, it would be because of Inosuke pestering and stressing him out.

Genya and Tanjirou grow extremely close, Tanjirou winning him over much like in cannon. Despite their vastly different circumstances, their dynamic doesn’t change much.

Genya and Inosuke fight as much as they get along. It’s either they are both united in a goal and will annihilate or eat everything that stands between them and victory, or they fight like feral cats. There is no peace with them in the same room.

Kaigaku is the last member of the nightmare friend group.

Initially, Kaigaku is a demon slayer who intends to kill Tanjirou for the glory of being the boy who killed the sun-resistant demon, but he ends up switching sides after getting his ass handed to him by a now Moon-breathing-trained Tanjirou.

Tanjirou, as is typical for himself, tries to befriend Kaigaku. It works better than Kaigaku wants to admit. At first, he’s hostile to Tanjirou’s kindness, and openly scoffs at the way Tanjirou sees the world, but over time, Tanjirou starts to have an effect on Kaigaku, making him actually take a look at himself for the first time.

Michikatsu is NOT a fan of Kaigaku. He refuses to train him or demonize him- both of which Kaigaku pleads for the second he learns that Michikatsu is capable of doing so. Eventually, Kaigaku does go through some character development and realizes that he does not want to become a demon, but until then, Michikatsu openly despises Kaigaku and his suck-up ways.

Kaigaku and Inosuke get along the worst out of anyone. This is mostly because Kaigaku absolutely refuses to entertain Inosuke’s self-image as a divine being and is openly dismissive of and hostile towards him because he was never a demon slayer and is not a demon, leading Kaigaku to think little of his abilities. Inosuke doesn’t often deal with humans disliking him, so he thinks that Kaigaku is possibly possessed by a foul evil and frequently tries to execute absurd exorcisms and cleansing rituals on him. Inosuke literally PRAYS on Kaigaku’s downfall.

They do eventually find a mutual respect, but I’m not sure if they ever get around to actually… liking each other.

Genya and Kaigaku get along better than you might expect. They both share complicated feelings for their demon brothers and they both can be more grounded at times than Tanjirou and Inosuke. Still, Genya trusts Kaigaku about as much as he trusts a pile of trash, and when Kaigaku learns this, it also causes him to consider why— and consider changing. From Genya, Kaigaku learns loyalty and what it means to respect your family bonds.

Anyway, uhh sorry 4 da long post

Feel free to send asks if you have any questions about da lore or just wanna see me draw these boys more :3

this one is just for the demon children, in reverse au. Let's imagine a scenario where they were found, still babies, by the demon reader who, whether out of curiosity or another reason, decided to raise them. It could be something short about them growing up with their demon father or the kids' impressions of what it's like to have a father who isn't human.

Adding to this is another scenario where a hashira (canonical, if you want to give names) finds the child with the demon and tries or even manages to kill the father and take the child with him. What would our three children's feelings be about this and what would they do?

Sorry for being so long, but your blog excites me

It's ok, I like these long texts at requests, to people to share their ideas and explain them. This looks more than a divergence than Reverse AU, but hey! It's 100% welcome here. I love to see everyone's concepts.

Reverse AU (with divergence) Demon Kids (as humans) having Male Demon Reader as a Father figure since young + Reader facing a non-character Hashira

Warnings: Implied child neglect and abuse, Implied child prostitution, Cannibalism, Attempted kidnapping, Angst, Implied non-character death, Reader's death (explicit),

Daki (ft. Gyutaro):

The boy (Gyutaro) holds his sister (Ume/Daki) close to him, she is barely a toddler, yet he must heat her up outside on the snow. Their mother doesn't like them in the house when it's winter. She doesn't mind them any other station, since she goes out to try and get clients and drugs, but in winter she stays inside, and she hates them. Still, three years old... he is still amazed of how much she is growing, and at the same time, worrying she isn't growing up enough. She neesd more food, better food, she also needs a warm place to stay, and many other things he never had. At his 16 years he works for it, collecting debts, but he can't leave her alone in this cold. What if she dies?

Then he notices a figure, a male adult before him, eyes glowing in the dark. He holds his sister tighter as you get on your knees in front of him. "You both smell like frozen meat, do you think you will survive the winter outside?" The boy ignores you, they can, they have to, his sister can't die like this, and that means he must also live to take care of her. "You look very weak, even if your smell says otherwise. You think she won't die with you? Such a pretty child doesn't deserve such a fate." He knows it. She is pretty, she is worth the world, unlike him, but that is more reason to keep her alive. "Ne..... ne... And what would you have me doing?" He can barely speak up, but he does. "Our mother won't let us in."

You took a look on the little girl. You know well this place, here she will grow up into nothing more than a shell that sells itself for the sake of food, add power if things go well enough. She is beautiful, you can tell even at this young age, she would definetely be able the find someone to buy her services the second she turns legal at 13 years old. And for that same reason you know she has no place in here, nothing worth the little treasure she is. She could be a lot more, a lot of children in this place could, but you have a better feeling by this one. Even now, as she grips tightly her only source of warmth, you see she is a survivor, someone determined. She takes it from the boy helping her, you guess, but unlike her, he is alreasy tainted by this place. You might have come earlier, but that would mean facing the Kizuki that lives nearby. "I can take her away, to somewhere safe. Somewhere she will have a better future than as a prostitute."

To his credit, the boy seems to consider it. He looks very distressed, not knowing what to do with the cub in his arms. "Can... I follow from behind? I promise I won't be a bother. I won't talk and stay behind, you won't even have to look at me. But... I need to take care of her... that way you won't have to...." He talks rushed, but shy, not knowing what to do. It's, a bit sad, so willing to do whatever gives her the life she deserves but unable to let her go, to thw point he is willing to become nothing but an accesorie in her life. You don't comment on it, while weak he does look old enough to live by his own. "What is her name?" Is all you ask, and he looks at one specific direction, probably his mother's house, for some seconds before answering. "She doesn't have one." Now that is weird, even demons have names. Even uou have a name of your own. "And what is your name?" Same reaction, but he seems less ashamed of the answer. "I also don't have one... people just call me different names... insults that... are for me. But she deserves a better name."

You end up taking both, mostly doting on the girl that you ended naming Daki, something with a potential to live on. While on the boy, he is sixteen, old enough to choose what he wants to be called, and you tell him so, waiting for him to come up with a name and tell it to you. He ends up choosing Gyutaro. A very ugly name, but you guess Daki isn't much better. In the end, Gyutaro is a lot more helpful than you expected. He is able to make up with few as you stay in caves, using snimal skin and your victim's possesion to build something, besides always having a campfire onn. You teach them how to write and read, and in the end it's Gyutaro who ends up feeding her and making sure she is healthy, always staying behind when you play with her, watching. You don't know how to apporach him, you never did, considering he was 16 when you found them, now he is fully an adult, even if he never became healthier or bigger, no matter how much he ate or rested, but he is stronger. He even decided to ho back to the district and take the job as debt collector again, comming every once in a while with money and gifts for Daki.

You make your mind on turning him too, once once the girl becomes an adult and you can turn her. The boy, now a man, is so strong he could easily become a Kizuki if he tried. Right now she is 13, and is playing outside at the sun, while you watch her over the shadow, using a little river nearby to entertain herself by splashing and collecting rocks. "Otou-chan, look! I found pretty rocks. Can you save them for me as I look for more? I want to give these ones to onii-chan, the next one is for you, I promise!" Such a beautiful child. "Of course, my little princess." But of course, the second she is some steps into the sun, you see someone moving fast into your direction, making you move back into the cave. "OTOU-CHAN!" She screams in fear, sound reaching you as the blade starts to pierce through your neck smoothly, too smoothly. Is this a Hashira? Your neck is almost completely cut by the time the slayer moves because out of reflex when the girl threw a rock at him, then only to keep grabbing things to try and stop them. You see the human trying to talk to her, tell her to run away, as she screams "NO! GET AWAY FROM HIM! I'M TELLING YOU TO STAY AWAY FROM MY OTOU-CHAN!"

You manage to get the scent of Gyutaro not so far. "DAKI! GO OUTSIDE! GO GET YOUR BROTHER!" It was a mistake to tell her that, you wanted to be safe, but the second she was out in the sun again and began to scream for Gyutaro, the Hashira cut your neck effortlessly, attacking you from behind before you could realize where he is. Everything because you were paying attention to the girl. The cut in the neck hurt, then, you began the desintegrate from thin air. It doesn't really hurt, but it fills you with despair, specially as you see the slayer go to Daki and grab his wrist. "What the- LET ME GO! LET ME GO RIGHT NOW! ONII-CHAN! OTOU-CHAN! HELP!" You hear her crying, slowly realizing in the middle of evevrything why you are not going to save her, still shouting for you as her beautiful voice breaks ans her eyes shed tears, still struggling against the man as she pulls her amr and hits him.

But... then there is a sense of calm, because suddenly, with a kanna on his hand, Gyutaro is behind the slayer. "Oi, oi, oi...." he says before stabbing the heart of the slayer before he could react. "What are you doing to my sister, ne?" At least she will be safe, and that is the only thing that matters right now. "OTOU-CHAN! OTOU-CHAN! NO! DON'T LEAVE! DON'T DIE! I WON'T FORGIVE YOU! I WON'T!" But there is nothing you can do about it. You look at your cub, wanting to smile but already being without a mouth, just sheding some last tears with her as... everything becomes a numbing black.

Kaigaku:

Kaigaku never met his parents, he was an orphan for as long as he remembers. You, on the other hand, don't remember having a child ever, but that doesn't mean you never did, with your memory loss. Most demons under Oyakata-sama do remember their past, you have no idea why you are different, but it has never stopped you from anything you wanted to do. You are able to run free, to eat, to make, to control... and yet, when you see a child in front of an orphanage, sitting alone in the dark, there is a nostalgic feeling growing inside you. Did you ever find another child like this? Were you a child like this? It's impossible to know now. But you are aware, this child is lonely... and afraid. He wants to survive, to live, he has determination. A fire- no. A thunder in his eyes.

"I'm not going to hurt you, little one." How old is he? How did human age work again? You don't even remember that. For you, he could be 2 the same way he could be 12. But he is young, young enough that his legs are too short, his face and body are chubby and lacks defines muscles. "What is your name?" You try again as he doesn't answer, doesn't move. "Kai.... Kaigaku...." he says softly, voice almost girlish as it hasn't reach enough levels of testosterone to sound like anything else. You look at him and you feel so much warmth and value from such small body. "Nice to meet you, Kaigaku. I would like to be your friend." Something in the boy's eyes lights up at that last word. "Will you be my friend?" And that was all you needed to take him with you.

You... do make mistakes. Like feeding him with raw flesh sometimes... it took you a while to realize he won't get used to it. You could always transform him, but you would rather wait until he is an adult for that. To let him live his childhood fully, without being tainted by thirst. You also realize fast he can't be out in the cold... and that he needs to drink heated up water as any other also makes him sick, and that his moods swings depending on if he is hungry or cold or sleepy, because he needs to sleep a lot more than you thought he would. Well... this IS harder than you expected. "We will live here from now on, Kaigaku." You say as you bring him to a warm, cozy home out in the middle of nowhere within the trees and definetely did nor belong to your last dinner...

But the boy is happy here, happier than ever. You start learning how to cook with books, realizing you have to also teach the boy to write and read. It's a bit hard... everything. But you see him grow up and smile everyday, and even form a temper. "To-san! To-san! Look! I killed a boar by myself!" And he also grows up too fast. He is definetely a teen now, an age he can already be considered an adult but... he is still your little one, that small and puffy kid you found alone in the dark. That is an image you will never forget. "Very well done, kid."

And then it hit's you, literally. A thunder breathing technique, no doubt, there is no other way it coukd have reached you fo fast before you even realized someone was there. The blad cut half of your neck as you grab it to avoid being decapitated. "To-san!" You hear your boy, your cub scream for you, and you have no idea what to do. Specially when you see the golden button in the jacket of the uniform. It's a Hashira! You have no chance against one. The only reason you are alive right now if because the slayer stopped his speed and strenght, probably to not risk hitting Kaigaku. It seems that same thing has saved you, because Kaigaku tries to get in between the affair, screaming at the slayer, who tries to take him away and explain the situation while he is attacked by the boy with a knife and keeping you at bay by cutting your limbs whenever you get close.

You are afraid he might loose his patience and defend himself against the cub, but also, the more you look at him the more you think. You don't want to die, you can't, not know, not when you are the only person in this boy's life. If you die, he will end up all alone in this cruel world. He doesn't deserve to be like that again, sitting in the dark, cold, alone and afraid. You can't let that happen again, but how can you face a Hashira? What might be ebough to deal with one? "To-san, run! I will distract him! I will see you back home!" "Don't do anything foolish! Kaigaku, stop!" You also lunge at the slayer to prevent anything to happen, making sure to cover your neck with your arm, the cub gets to scratch the face of the sword user before being sent away by a strong push, flying to the side as you jump to catch him. The boy is unconscious, and you have to let him fall on the ground amto evade another slice on the neck, barely making it again.

You just... care too much for this boy to leave him. Even if he isn't yours by blood... by blood. That... that might be it. You see the scratch on the slayer's face, it still bleeds a little.... it might work, you loose nothing trying. You must try. When the human is close again, you rip off your arm. It hurts, a lot, but it bleeds directly into the Hashira's face. Usually demons don't rely in hurting themselves, but you are desperate. You need to save Kaigaku. The blood in his eyes blinds him for a while, enough for you to throw your arm at him, grab the boy and run. The transformation should start soon, and if you are lucky, the slayer will kill himself before it even begins the second he realizes demon blood touched an open wound.

You barely make it home before sunrise, but you do, not managing to close the door, but still hidding in a shadow. Your arm hasn't regenerated fully yet, and Kaigaku is still asleep. You let him wake up by his own. "To....-san?" You soothe him with your good arm. "Don't worry, kiddo. We are fine. We made it. All thanks to you." He really has a thunder inside him. He seems to calm down, only to cry his emotions out as you comfort him the best you can. Paises, pats, hugs, everything you can do right now. It's fine, it will be.

Zohakuten (ft. Clones):

"YOU DID WHAT?! HOW DARE YOU?! I SHOULD KILL YOU FOR IT! YOU PROMISED HIS MOTHER YOU WOULDN'T THROW HIM OUT!" When Hayato (Urogi, 13 years old) and Kazuo (Aizetsu, 12 years old) overheard Toshirō (Sekido, 17 years old) and their father arguing, they ran to the street, where Zohakuten (who the fuck names their child "Hatred"?) was thrown, a four year old thrown into the streets. It seems that is what the two eldest are fighting about, since it happened when all of them were away, even now Masami (Karaku, 15 years old, the only one who already goes by that name in the streets) is still at work, so they can't rely on him while searching. Did he ran away? Was he taken? Have they failed their youngest brother already? Attacked by an animal? It's already dark, who knows what happened, and they don't exactly live in a safe area. Then in one turn, they see you, picking him up as he sleeps in your arms.

"HEY! HANDS OFF! THAT'S OUR LITTLE BROTHER! GIVE US ZOHAKUTEN!" Screams Hayato as Kazuo grabs him, sensing something wrong about you. Your eyes glow... why are your eyes glowing? "Hayato, one of us should look for Toshirō or Masami." You were about to answer when you have to move fast to evade a blade in your neck. A slayer? You jump towards a ceiling to look at that person better, still holding the child that grips you tightly in dreams. Such a precious and unprotected cub. From an open window from an inn a another human, similar to the other too, shows his face, clearly sweaty, covering himself with a sheet, smelling like arousal. "HEY, BASTARD! COME BACK HERE! YOU STILL HAVE TO PAY ME! I DIDN'T TAKE ALL YOUR SHIT UP MY ASS SO You-..." He shuts up when gazing the other two. "Hayato? Kazuo? What are you- Where are Toshirō and Zohakuten?!" He smells afraid now.

Thankfully, it was a weak slayer, slightly drunk, definetely tipsy. Easy to kill once in his blind spot by a hit in the neck. The two first humans paralyze at that while the green-eyed runs, already dressed. You were going to leave in the silence, but the third one arrives. "Wait! Wait! Don't take him!" He blocks your path, annoying you slightly. "I know what you are, you... he won't taste that good. I... I can offer a lot more. I can serve show and dinner... willingly! Amuse you for as long as you need then you can just eat my flesh, but please let him down... I am good at-" "Silence." He does obey you, even if he looks as if he is about to cry or laugh, probably both, but he still doesn't move or relax, looking at the cub in your hands. A few seconds pass as the blue-eyed human speaks, hugging the gold-eyed one's arm. "Please. Just give him back. We were just looking for him. It was our father the one who threw him out. We want him back. We will take care of him, just... don't hurt him or Masami. Our onii-san is working on the matter, it won't happen again, we promise."

Then there is suddenly a scent of blood nearby in the area that wasn't there, big amounts, full of alcohol. "Blood and alcohol nearby." All of them seem to pale as the cub stears, you rock him in your arms in an attemp of calming him down. "Please... Toshirō... we.... I'll do anything. Toshirō is important to Zohakuten." You both spend the time in silence, until you settle for a compromise."I won't hurt the cub. I carry him to his home with you." They can't trust him with you, nor you can trust him with them. But still, it's acceptable enough, even if the Masami one takes the slayer's sword with him. When you arribe to the house, too small, dirty, smells like alcohol all over, you find a red-eyed version of these humans besides a corpse, being badly hurt himself. "Toshirō! Toshirō, what happened?!" The Toshirō one is panting, grabbing his wound in the stomach, before talking. "He is dead, we must leave before anyone else finds out."

You just grab the cub when everything happens. You all end up in a house of your victims or caves, moving together, since nobody can do anything about it. Zohakuten is stubborn and attatched to each one of you, as you are the one who take care of him most of the time, he starts calling you "papa". They changed their names to emotions, except Karaku... he said he was already recognized by that in some places and he wanted to keep working, so he would keep it that way. The others also begin to work, but Karaku dis keep the sword. You wonder if he would joing the slayer corps if it wasn't because he is afraid you will hurt Zohakuten. "Papa! Papa! Let's play!" You wouldn't, not this beautiful boy. Between all of you, it's easy to keep him happy and give him everything he needs, specially when all of them reach adulthood. "Papa, can we go out and see the stars? I really can't sleep."

You were never able to tell him no, that was something that for once, you shouldn't have done. You went out alone while the others were asleep, and suddenly... you need to cover the boy as you are attacked by a sword. You remember the night you took the boy in your arms by the first time, this slayer is muchas faster and stronger. Is he a Hashira? Probably. This means this time you are fucked. Also, a difference from that time is that Zohakuten is awake, so he screams. Both the afraid voice and the cut are painful, as you move to try and let him on the floor to face the slayer. A bit of your blood feel on the cub's face, what if the slayer attacks him thinking there is a risk of transformation?

"Kid, you need to run back home! Go back to your brothers!" You say without taking your eyes off the Hashira, who doesn't take them off you in exchange. "Go!" You urge him as the slayer ruches over you the second your skin begins to heal, making you grab his wrist while you duck. "NO! I WON'T LEAVE YOU TO THIS BULLY! THIS VILLAIN!" As endearing as that is, it's not the time for that. He needs to get out of here. "I can handdle it for now. Look for the others so they can help!" Ypu lie, there is no way you can survive against a Hashira by your own enough time for a 12 year old human to go all the way home and back. But you have a priority. "Listen to your papa, go get help!" After some seconds of silence, "ok...." he runs away, you can only hear his steps.

He will probably cry and curse you, he does have a bad vocabulary, courtesy of you and Sekido. Sekido will probably lead the process of moving on without you, he could feel Karaku thought of you as a threat, only keeping you around because he felt little of a choice, not liking or trusting you, having Aizetsu and Urogi around you all the time. Had you listened to him and brought one of them with you, you might have survived. But no, you are beheaded easily and left for death, but you did manage to run away on the opposite direction to hive Zohakuten time to get home. Urogi and Aizetsu will at least remain comforting the little guy, and Karaku will, as always, keep working.

Your heart aches as you die alone in the dark, wishing to have been able to comfort the cub one last time, or at least say goodbye. But it's over, and at least he will never be alone as long as he has his brothers, hence, you beg they never become slayers. Never.
