Small Spoilers On How It'd Possibly Go:

Love the whole AU. How it's pictured, described, and how it definitely leaves the reader with the same feeling of hopelessness as the women there, but just gotta ask for my overly creative and wild head: How would all the demons deal with a new clan that's known to treat women as the most precious beings and are slowly stealing the demons' "wives" and into their clan to help recover them? Also, can I write my own small mix of this AU of yours with that idea? I can't explain with words how much I love both "helpless and hopeless" and "terrifying diety women" tropes. I won't if you wouldn't agree to it.

Red Concubine (demon slayer Handmaid AU)

Kotoha’s mouth felt dry. She shouldn’t be surprised, but it was unnerving to hear it said with such nonchalance 

She didn’t know much about Upper Moon Four, but she knew Sekido—and by extension, Zohakuten—by reputation.

Cold. Cruel. Unyielding.

Sekido wasn’t like Douma, who wore a mask of charm over his depravity, drawing in victims with honeyed words and empty affection. Sekido didn’t bother with the act. He was rage unfiltered—merciless in execution, with no tolerance for disobedience or failure.

They were feared by all. Servants spoke their names in hushed whispers. The Shusei lowered their eyes when they passed, their very presence enough to drain the blood from a man’s face.

Everyone knew what had happened to Lady Shinobu’s previous demon Shusei.

A single insult. A moment of misplaced arrogance. That was all it took.

The punishment had been legendary in its brutality.

Skin bubbled and peeled, burned off in layers—only to be regenerated and scorched again.

Her brain liquefied within her skull, over and over, each time forcing her to relive the agony anew.

Her tongue was torn from her mouth. But that was not the end of it.

Zohakuten, with the same serene malice he wielded in battle, had forced his wooden roots down her throat, shoving them deeper and deeper, watching as her body convulsed, choked, and spasmed—as if she were a mere insect pinned beneath his fingers.

It was a warning. A demonstration of power.

To insult Upper Moon Four was to invite a fate worse than death.

And here we have two situations with our boy Akiyo, Sakuro x Maylis son. The first 3 are from the last fight and we have Sakuro being a protective dad with Akiyo.

The responses and examples of what I'll do for him will concern every woman who fought for womens rights and to live normally.

Since the design material collection books finally arrived, I was able to scan some of the pages and visualize the demon's heights. Some of them are officially stated while for others, I had to approximate based on comparison. Explanation for each of those is stated below.

First of are Muzan (179 cm), Kokushibo (190 cm), Doma (187 cm) and Akaza (173 cm). Their heights are all officially stated in the Demon Corps Records.

Next are Hantengu (166 cm), Gyokko (between 150 and 170 cm in his vase), Daki (~ 178 cm) and Gyutaro (~ 190 cm). The later two don't have an official height mentioned but the size of the head is a good measure to compare the characters in the official designs. Daki is of course taller because of her shoes, while in the anime, Gyutaro is hunched over a lot. But from the image of the design material from the Entertainment District Arc which I've used, you can see what his height is standing straight, or at least as straight as physically possible for him.

I'd like to add that while Gyokko's height is known, if you go based off the official art, he can be taller than 170 cm, depending on how straight he positions himself and how far he comes out of his vase.

Hantengu's clones

Looking at the clones next, you can see Zohakuten (~ 165 cm) and first-split Sekido and Karaku (~ 190 cm). Zohakuten's height is more or less official since we are shown the direct comparison with Tanjiro. The other two were again compared with the head sizes and proportions.

Second-split Sekido and Karaku as well as Aizetsu and Urogi are generally the same size (~ 190 cm) since their proportions don't really change. However, Urogi's anatomy generally affects his height, but not too much as when he's standing on his legs, his hips would be around the same height as the others'.

The smallest of the clones is the main body / fear clone (~ 19 cm). The tallest being Urami (~ 260 cm) who is seen directly next to Tanjiro in the design material.

Gyokko's height when morphed

Morphed / true-form Gyokko (~ 215 cm) is directly compared to Muichiro whose height is known (160 cm), making a visualization of his size easy.

(An approximation of his tail length may follow.)

Ranking

From tallest to smallest, Muzan and the upper moons as well as their other forms can be ranked as followed:

Urami - 260 cm

Morphed Gyokko - 215 cm

Kokushibo ︱ Sekido, Karaku, Aizetsu and Urogi ︱ Gyutaro - 190 cm

Doma - 187 cm

Muzan - 179 cm

Daki - 178 cm

Akaza - 173 cm

Hantengu - 166 cm

Zohakuten - 165 cm

Gyokko - ∅ 160 cm

Hantengu / Fear Clone - 19 cm

What?

And no.

I don't know how I forgot about Toyotama-hime's older brother, Hirakugo. He's taken the albinism from his mother and is a Moon breather with a white Nichirin sword. He also has Kokushibo's eye colors and short fluffy hair. His personality is just the exact same as Kokushibo and absolutely hates uppermoon 4 Hantengu because of his "fake innocent" act and would just want him to at least do the minimum and not tremble and stutter as much in front of Muzan (he thinks it's disrespectful to do that in his presence). He's just basically a second Kokushibo, but an albino version with short hair.

@hantengudelulu, @fallstreakfeathers, forgot about him. Sorry 😞

what was the very first thing that got u into fandom?? like what tv show made u look online for more

The anime of Demon slayer got me into the fandom.

I won't talk about how I got into countryhumans... Thankfully, I'm not with the stereotypical side of them.

@hantengudelulu @virtuousweakling, if biblical angels were in the demon slayer universe, would it be possible for them to scare the shit out of demons? Like, I'm just continuing to imagine Archangel Michael fucking up every demon he sees without a break.

((This is also my call question if I could actually make up a fic like that, it's too good of an idea))

Wanna know something? He ain't never did that shit. He literally said to love everyone, or the least one can do is respect them, but no. Some delusional asshole will continue to be cowardly dicks.

I do apologize, but I got obsessed by this comic from Deroniecomme from X and I would like to share it here.

Here, we get introduced to some new characters: Hakuma, Kojiro, Akiyo and the Angel Hashira (still don't know what name it was).

Hakuma is Hantengu's clone of disgust and Kojiro is the clone of insanity of Hantengu.

All the while, Akiyo is Sakuro's son with his mother Maylis.
