#demon zenitsu au

[chaotickasugaicrows]

Demon Zenitsu design for an AU where Zenitsu gets turned into a demon and Kaigaku has to work on a cure without letting the Demon Slayer corps know what happened. Hence the disguise.

The title of this chapter may be a little bit cheeky, but I think it fits, for a chapter that is entirely pwp. Yes, 8k words of disrespectful smut serves the plot... because... *checks flashcards* "it develops/furthers the relationship between the two main characters" ... yeah. that's it. definitely. but in all seriousness, I hope you all enjoy this chapter. I've been getting some lovely feedback and I really appreciate all the love :,D it makes me happy to know I'm not posting this story into the void. so thank you guys for reading!! much love <3

[quozacheese]

kny if the Kochos were the main characters

[scarymonsters-andsupercreeps]

Just saying we were completely and utterly robbed of a Mugen Train-style arc where the gang goes on a mission with Gyomei and they follow him around like ducklings

Edit: here’s a small comic I made!

[orange-artist]

KNY Time Travel AU

Notes about time travel au (hashira kamaboko squad):

Tanjiro

He learned that the longer his hair was the more pissed Muzan gets so he let's it grow out. However he can't handle it too long so it's stays a little over shoulder length and he ties it up

Mastered sun breathing and tried out the other breathing forms to make up for the fact he learned through unconventional means. Aka. He knows moves from all the other forms

A little bit of demon blood in him because of his brief (attempted) possession. Enough to cause him to be slightly more demonic than humans. Heals faster.

Zenitsu

Still wails and whines but mostly performatively

Will gear shift in an instant to seieous mode and it's terrifying to witness

Wasn't able to master the other forms of thunder breathing so he modified into his own style raiden (lit. Thunder and Lightning) aka Thunderstorm breathing to fill in the gaps.

Nezuko once complimented him about his long hair and he's committed to that ever since

Inosuke

Eventually realized people kept thinking he was a demon when he wore the mask so they compromised and he wear it on his shoulder now. He still occasionally wears it.

Had a brief obsession with learning all the manners so he can disregard them on purpose

He's learned to consider consequences, not that he spend a lot of time doing that but still

Got coerced into wearing a bit more cover ups by the squad a la goading and compliments

Nezuko

Half human half demon, wasn't fully cured

She tried to learn a breathing style and managed to somewhat grasp water and flower but she's not as talented as tanjiro in sword fighting

In a fight, she prefers tantos and daggers, if not directly hand to hand

She excels in tactics, the team eventually realized she should be planning the fights

She is able to control all the boys, no one questions the Nezuko

Genya

Thanks to Nezuko's antibodies and Tamayo's efforts, he's okay when he uses his abilities

While not able to use a breathing style still, he's made up for it by training and skills. He's making a mostly a marksman of the group, with phenomenal aim and wisteria bullets made by Kanao

Full mastery over his abilities and is able to control how much power it uses and how long it lasts

Wears Sanemi's outfit…

Lowkey kinda died but managed to get revived…🤔

Kanao

Emulates Kanae and Shinobu to an extent but she's more open about how she's feeling

Changed her cape into a floral orchid haori

She still has her coin but it's mostly for cool factor™️ now

Learned medical and poisons and demonology eventually

worked with Yushiro to try and develop a cure for the curse of the demon slayer marks

Hehhehehe thoughts?

[artsbyryn]

Inosuke cannot get Nezuko's name right.

[yuki2sksksk]

can we see gyutaro in the mermaid AU

I would be amazing

(And daki ofc)

I haven't figured out everyone's lore yet (lol) but here are the mermen of this AU and sea creatures they are based off, either from look or other traits.

(why Giyuu is an eel? Cause my first thought when I saw that eel was 'whats up with this dude' which is the same phrase when I first saw Giyuu)

Do you know that Tiger Shark eats almost anything? Kinda like Genya with demons, they're both gluttonous :)

I thought of having Gyomei with Basking Shark but I am still not sure.

There are a lot of things I am unsure about, like Douma cause my first choice was Crocodile Icefish and why is Yoriichi a small fish? Cause I said so (honestly Idk what to put him as)

I thought of Akaza as mantis shrimp cause they pack powerful punches tho hrmm I am not sure.

I promise I am not doing Tanjirou dirty (iam)

Him and the fish have too many similarities. Like their forehead.

If you guys have any suggestions of sea creatures they can be based off, please do comment (⁠✯⁠ᴗ⁠✯⁠)

[Masterlist]

[minthy]

just hear me out..

(not a AU, just comparisons? for fun)

[imkazz]

for some reason tonight i cant stop thinking about different pairings for the infinity castle arc. what if shinobu had met akaza first, where she reminds him of poison-users, but he can't attack her due to her gender and her revenge wouldn't work on a demon who doesn't eat women? what if it was gyomei who met kaigaku, and genya with him seeing just how bad older brother figures could really be? or tanjiro and muichirou as a team meeting kokushibo, reminding him of yoriichi in different aspects of themselves. sanemi getting frustrated over douma's fake personality while giyuu takes no shit because he's so used to shinobu poking at him. iguro and yushiro finding each other first and sort of getting along because each of them worship a girlboss. mitsuri meeting inosuke and his loud personality who doesn't understand social norms, meaning he doesn't care that a woman is strangely strong. kanao meeting zenitsu against like nakime or someone where each of their heightened senses picks up fear from the other, and though they have multiple different reasons, one similar worry is failing those they love.

like. hello? there could've been so many different lifelong relationships if nakime had strum her biwa even slightly differently.

[imsosleepyofyourbull]

This is an impulsive draft of a scene I thought up based on @orange-artist‘s Time Travel AU of the Kamaboko Squad… if you read this, know that I love your art and that I genuinely can’t stop thinking about it. Please enjoy the hyper-fixation soup of words that I call my unedited writing!

“Kanata and Kiriya,” Kagaya gasped, his usually gentle and composed features overrun with surprise as he desperately hoped he had not misheard them. “How… how many of the children did you say survived this year’s Final Selection?”

“Of the thirty-three test takers, thirty-three have passed and will continue to serve the Demon Slayer Corps,” Kanata replied dutifully.

“Of those thirty-three,” Kiriya continued after, already anticipating their father’s next question. “Five were noted to be especially skilled.”

“The independent swordsman who developed his own breathing style, Hashibira Inosuke.”

“The independent swordsman who does not use a breathing style, Shinazugawa Genya.”

“The youngest student of the retired Rumbling Pillar Kuwajima Jigoro, Agatsuma Zenitsu.”

“The newest student of the retired Water Pillar Urokodaki Sakonji, Kamado Tanjiro.”

“And the only student of the current Insect Pillar Kocho Shinobu, Tsuyuri Kanao.”

Kiriya gave their father a moment to commit the different names to memory before concluding, “the remaining twenty-eight state one or more of these five had saved their lives at least once and stayed close by until they were healthy enough to survive the rest of the week. We saw each of them waiting at the edge of the forest for the rest of the stragglers before passing themselves. Additionally, the Kasugai Crows we sent on a final expedition of the forest afterward reported that only one or two of the demons were left alive.”

Kagaya had believed the Miracle Selection to be a once in a lifetime phenomena — marked by a lonely gravestone in their strange family’s shared cemetery and the memory of a peach colored fox wielding violent waters in defense of its peers.

Unimaginable, and unrepeatable.

He was right, but only because this Miracle Selection was nothing like the first. This one was intentional and decisive and everything that his family made of blood, bone, and steel had been waiting for. The beginning, or perhaps just the first visible omen, of a change in the very course of the world that Kagaya had been unable to foresee until it had already happened. Was it any coincidence that there were thirty-three survivors specifically? That, of those thirty-three, five of them in particular had saved the rest?

The Ubuyashiki were superstitious by nature; marrying their heirs to the daughters of priests and teaching their children to create rings of salt around their beds when they wanted some extra protection at night. The importance of the numbers three and five were not lost on him. With the three sacred treasures and the five directions (the five senses) marking their way, there was no question as to what he must do. Kanata and Kiriya know it too, or they would’ve sent a crow instead of making a personal report.

“Tell our most reliable kasugai to follow the five children you just mentioned,” he ordered Kanata, “they don’t have to be especially quiet… though I would appreciate it if they were undisruptive.”

He could not see her, but he knew that she gave him a solemn bow before turning to leave.

For Kiriya, “I need a missive to be sent to all of the currently active Pillars as well as the retired Rumbling and Water Pillars for a meeting at the northwestern estate three months from now.”

“Understood.”

The tide of change was fast approaching, and he knows that it will spell the end of this centuries long battle against the night. Kibutsuji Muzan will not live to see the next era — that, he promises.

(What he does not know just yet is that his chosen children have already sat on the horizon of a demon free world, and they know that they cannot afford to fail twice. Once was enough.)

[demonslayerunhinged]

how different do you think demon slayer would've been if they had modern stuff like phones, social media, video games, better transportation, T H E R A P Y?

Would there be constant online arguments between the hashira and the upper moons?

Just curious on what you think would happen if this were the case

Hi anon! Sorry for the late reply! Here are my headcanons with a little SaneGiyuu sprinkled in of course.

The Hashiras and the Upper Moons would definitely have Whatsapp chat groups where the Master would call them for meetings, they would discuss about their missions and they would clown on Giyuu 😂

The therapy would be one of those closed room sections where they can rant about their colleagues and missions kinda like the way contestants do in Big Brother or Total Drama Island.

...

The Infinity Castle would be an office similar to how it is in the Gakuen. Akaza is desperate to make Rengoku a demon because he needed a (boy)friend in his toxic workplace.

Kokushibo is the bossy, know-it-all who thinks he's the second boss, he definitely has the company logo as his social media profile pic and talks about putting the company first yada yada yada

Douma is the snake that pretends to be nice to you but talks about you when you're not around, preys on the new female hires, and has a special seat reserved for him in the HR department.

Nakime is the colleague that keeps to herself, does their work, doesn't really talk to anyone and peaces out once it's 5.

Gyokko is the suck up who tries to see how far they can push their nose up the boss's ass to get a promotion or recognition.

Hantengu is the old head that pretends to be incompetent and pitiful so that you'll end up doing all their work

Gyutaro and Daki are the gen-z types that hate the job but need the money, won't stop questioning authority and who you're secretly jealous of because of their gutsy behavior.

Akaza is the only sane one who has an already drafted resignation letter saved on his computer desktop that he wants to submit every Monday or everytime Douma opens his mouth. He copes by scrolling through office/shitty colleague memes, snorting coffee and dreaming up fantasies about the office exploding.

Douma has been banned from the Upper Moon group chat for posting too many memes and Blue Spider lily troll posts.

...

Giyuu constantly forgets the gate code to the Master's mansion when there's a Hashira meeting and when he asks on the group chat the other Hashiras mostly ignore him.

Sanemi dms him and gives him the code after calling him a dumbass.

Gyomei is always posting cat pictures and videos on the group chats.

Tengen takes a selfie during every mission and posts ot on his status.

Giyuu's driver is always late because he is old and always forgets where Giyuu's house is but Giyuu doesn't have the heart to fire him because the driver cares for him like a grandson.

Sanemi drives himself to his missions.

Rengoku always types in capital letters and Obanai is always asking why he's shouting.

Mitsuri has an Instagram where she posts about fashion, her cats and food. Obanai likes every post, he also likes every Mitsuri group chat post no matter how silly it is.

Whenever Rengoku goes on missions, he always visits the restaurants in the area and gives ratings and reviews on Google Maps.

Muichiro, Genya, Kanao, Inosuke, Zenitsu and Tanjiro spend their free time on their shared Minecraft server making cool builds.

Zenitsu screams whenever there's a creeper around, Inosuke just runs towards it like an idiot. He has the highest respawn rate out of any of them.

Tanjiro always greets each of the villagers he encounters, he's even nice to the traveling merchant. He also has a lot of dogs and cats. His base is in the jungle because of the pandas. He likes to explore and collect lots of resources.

Muichiro, Kanao and Inosuke like to explore the caves. Inosuke likes to sneak into Zenitsu's base and steal his stuff. He also has a lot of dogs which he calls the Hoard.

Kanao makes fancy builds and has a lot of xp, food and resource farms because she values efficiency and she always shows off her builds to Shinobu and the butterfly girls. She's the first one in the group to get netherite armor and sword.

Inosuke is banned from several stores and malls especially Walmart.

Sanemi and Obanai play COD together and bully/kill teammates or other players who are misogynistic and shout slurs.

Giyuu saves the Hashira's names formally on his phone but saves Sanemi's with his first name.

Giyuu and Sanemi text each other constantly and Sanemi always asks if he's eaten and offers to cook food for Giyuu at his place.

Shinobu always trolls Giyuu on the groupchat and she's banned from several pharmacies for her questionable requests about poisons but has settled for ordering them from the dark web.

She's currently on a watchlist for her ties to several eco-terrorist groups. She had a channel where she talked about poisons and bombs but it was taken down by YouTube.

She often takes the butterfly girls for ice cream and they have movie nights. Her favorite movie is Jennifer's Body and Mean Girls, least to say Aoi and Kanao are very concerned for her.

Muichiro always has to explain gen-z slang and memes to Gyomei.

Tengen is always posting thirst traps on Instagram along with pictures of his wives.

...

Kokushibo always handles Muzan's Amazon orders. Muzan orders a lot of hair products, he shops at designer stores and has a Sephora membership card.

Gyutaro and Daki are always bullying kids on Roblox and griefing peoples builds on public Minecraft servers.

Gyokko's Instagram page features his pots and 'art pieces', Hantengu likes all his posts.

Akaza listens to Avril Lavigne and posts about his colleagues and how he hates his job on Reddit and Tumblr.

The Infinity Castle wifi password is Muzan4prez set by Douma of course.

Nakime's favorite channel is HGTV because she's always looking for ideas on how to redecorate the Infinity Castle.

Muzan always watches E! especially when the Awards Season comes around. He's especially fond of the Met Gala. His favorite show is Hell's Kitchen.

Kokushibo likes watching the National Geographic channel and NatGeo wild on occasion.

...

The Master always forces Shinobu, Sanemi, Obanai and Giyuu to have professional therapy sessions. He also checks up on them to make sure they go every week and bribes them with movie nights with him.

He always posts motivational quotes and positive messages for the Hashira but isn't above posting memes and troll posts every once in a while. Sanemi likes all of his posts, chats and comments.

...

That's all I can think of for now. The slaying of the demons will be the same, they would still use katanas because they're more efficient than guns.

No matter how many lives [UM6 Zenitsu and Kaigaku Fic + human Ume/Daki and Role swap kamaboko siblings]

(will also post this on my ao3)

This is your fault asshole!” The blond brats head yelled from his place on the ground the Kaigaku who head yelled back “Huh how this my fault wimp!” Kaigaku snarled “You and your dumbass hair eels should have ripped apart the ribbon sword wielding brat!” The blond rolled his yellow eyes.” I couldn't, that idiot boar was still alive and managed to slice them all off! Why didn't you help me!” Kaigaku once again snarled “ I was too busy dealing with that stupid Hashira! But the slayer with pink eyes was still alive so I figured I should have dealt with her first since you keep whining about wanting to eat her eyes!” The blond growled “I could have taken care of her on my own! You scum this is all your fault you trash-” Kaigaku finally snaps “SHUT UP!” the blond shocked finally stops talking “ Don't give that crap! IF ANYONE HERE IS TRASH IT'S YOU!” Kaigaku doesn't notice the tears coming out of the quiet blond's eyes nor does he notice the slayer in the pink kimono and her demon brother watching them from afar. Kaigaku takes a huge breath and continues to yell “IF YOU WERE ON YOUR OWN YOU'D BE DEAD BY NOW!” The younger brother's tears leak out even more but Kaigaku continues, his voice becoming softer but still full of rage “Your the useless one and you know it you can't stand on your own feet… DAMMIT IF IT WASN'T FOR YOU I WOULDN'T BE DY-” A hand covered his mouth muffeling his words. It was the black hair girl slayer “Don't say that you know you don't mean it.”Think about everything you've done no one will forgive you.” She took a shay breath “All you have is each other so please stop fighting” The blond finally broke and began to sob .”Why don't you mind your own business!” He sobbed and yelled louder “Who do you think you are to lecture us! Do us all a favor and get lost!” his voice became softer when he spoke again “I can't believe this is happening. I'M NOT READY TO DIE YET! I DONT WANNA DIE ANIKI!” Kaigaku was in shock even though yelled at him calling him useless and trash his younger brother sought him out for comfort.“Please help me Aniki” the younger face finally began crumbling and Kaigaku could only watch in despair as his baby brother disappeared “ZENITSU!!!” That's right, his brother's name was Zenitsu. Kaigaku felt himself crumble and everything went black

Nezuko held the disappearing head in her hands while her older brother in his toddler form looked at the display with sadness in his eyes feeling a bit pity for the brothers. Nezuko spoke after the head was fully gone “ I hope they made up

Hello hello, I know this chapter is shorter/less eventful than usual, but I needed to create a bit of an interlude, because the upcoming events 👀... I had to break it up because of that. I hope you all forgive a less edge-of-your seat type installment, but i do think the contents of this update make a nice bridge between "parts" of this story. I'd consider everything that comes after this chapter as "part two" of a bigger narrative. anyhow, I hope you guys like it! thank you so much for reading, as always! it makes me very happy to post, knowing y'all are excited for it! :,D I'm very grateful <3 :,>

[quozacheese]

in my head, they're bffs

[vinlynce]

Misc characters part 1 plus a different Uzui bc I ended up changing what I wanted to do with him for the au The idea with Nezuko is that the main drive for Tanjiro and her's entry into the guild is that something happens to Nezuko causing her to semi-evolve in spikes based off strong emotions. Almost always multiple eeveelutions at once have traits pop up at this with the exception of Espeon. Whiiich is what she finally evolves into after their fight with Hantengu, causing the uncontrollable semi-evolutions to stop.
