Kny Mermaid Au - Tumblr Posts

Ocean Deep Ch1 Premise

In a world where inhuman and human creatures lives side by side, sometimes it was difficult to navigate where things were. So there was rules EVERY human followed. Don't engage. If you left them alone then they almost always left you alone... Unfortunately it's difficult when a whole pod happens to be under the impression that you belong to them.

IMPORTANT WORLD INFO:

This is set in a fantasy world with very little tech. Think Howl's Moving Castle kinda tech world. Also more Bride concept cuz I like it.

This is heavily inspired by @firelillys on Tumblr merfolk au. Please support all artists linked/mentioned here with their own works!  I'll be providing important info for our mer cast and leave links for a better image of what they look like. I wanted to pick pretty fish for them all so some of the original fish ideas were scrapped from the first drabble.

KYOJURO:

Kyojuro would be a lionfish such as the one drawn by @yuki2sksksk on Tumblr linked below.

Yuh

Lionfish based merman Kyojuro and Betta fish based Akaza! (Ft Inosuke the same fish as Akaza but he has split/double tail while Akaza has cr

TENGEN:

Tengen would be a white butterfly koi fish and would look like the linked post below except less eel and more butterfly koi also below.

Merman Tengen (minus the eel like features)

HINATSURU:

Hinatsura would have a tail that starts out red then fade to pink and would have sorta spotted like patterned semi flowing fins being a Strawberry Peacock mer.

MAKIO:

Makio would have an orange-gold tail with flowing fins being a Golden Dragon Koi mer.

SUMA:

Suma would have a blue tail with more ruffled fins compared to everyone else being a (all blue) Halfmoon Betta fish mer.

With this out of the way let's get onto the chapter.

In a world where inhuman and human creatures lived side by side, sometimes it was difficult to navigate where the danger lied. No where was safe. 

The fae ruled the forests. Fairies and elves. Pixies and gnomes. Pans. Mischief makers. If not careful they'd whisk you away. Never to be seen again.

 The dwarves and dragons claimed the mountains. Proud and strong. If insulted they'd be incredible does to crush you.

The skies were never safe either. Run amok with harpies. The plains ran with herds of centaur. The night plagued with vampires, werewolves, and demons. The day ran with fauns and tieflings and shape shifters. So many dangers and so many things to look out for. Especially when it came to courting a mate. As they say

"Beware the monsters who lurk and live amongst the world. Beware of those who seek courtship from maidens. Do not engage. If you ignore and leave them alone then they'll almost always leave you alone."

You must learn to learn their language and not be tricked by anything. Stay alert. Stay aware. Always stay vigilant.

And never let your unmarried daughters near them alone-

The sky was beautiful today. That's all really you could think to yourself. The fresh scent of flowers filling your sense of smell as dead flower petals was swept away with the dirt and dust. With each step you took the sounds of distant crying was heard. F/c eyes only stared at the floor where bristles met the ground and pushed them all away... Eventually you did spare a look briefly over your shoulder and felt your heart sink. 

The Kocho family stood there. Or..what was left of the family.

The man hugged his wife tightly to his chest as she sobbed uncontrollably into his shirt. It was the most recent travesty really. Two months ago their youngest daughter, Kanao, had gone down to the river just down the old dirt road and through the woods a bit, to gather more herbs which they sold alongside the medicines in their family shop but she hadn't returned for a few hours. Then when their two older daughters went to go look for her, they two never came back. Panicked, a group of men including Mr. Kocho and the girls' grandfathers had gone out on a wide man hunt searching deep into the nearby woods and combing the long beach nearby for any trace of the missing sisters. Nothing ever came up. No footprints or scraps of fabric. It's like they've never even existed! Some say that they were claimed by fairies. Others say a ghost spirited them away. One person whispered that a flock of harpies might've flown them away.

Whatever the case, they were gone and it's unlikely that they were coming back.

The parents had already accepted that their girls were probably not coming back and was here to make flower arrangements for a memorial service the family was hosting in their honor and memory. Your boss was standing in front of them holding a few sample petals for them to choose from. In the middle of their talk, Mrs. Kocho had burst into tears, so the older woman gave the couple a moment to process their own emotions.

This wasn't the first time a young girl disappeared into thin air. 

When you were a little girl, your next door neighbor was a beautiful woman named Rei. Her pretty brown eyes and kind personality made her a favorite person to everyone. She loved going on night walks, but one night she didn't return from her walks. Her father moved his entire business three towns away a little after that. Another case was a girl your age who disappeared last year, Mitsuri. According to her brother, she ran into the woods to be alone after her fiance brutally broke up with her. As he went to find her, he saw her being carried away by a giant black and white naga, the boy had fled as fast as he could back but by then it was too late. Then later that same year, you heard rumors about a girl named Koyuki and her father disappearing from a boat ride near the river but since that didn't happen in your town, you didn't know if that one was true.

It wasn't always young women either. Sometimes it was young men that went missing. A famous case from up the mountains was the disappearance of Kagaya Ubuyashiki. The last anyone had seen of him was he was walking along a patch of birch trees. Witnesses said he was last seen speaking to a white haired woman before he vanished. People say she was a white birch spirit. Another famous case was Tokito. Again not in your town, but he was a lumberjack that often went into the mountains for wood but one day never returned.

Nevertheless it was both scary and tragic. 

Which was why there was a few unspoken rules your parents always taught you before they passed away. Never go anywhere alone. Never trust mysteries strangers. ALWAYS carry protection with you. Never go out late at night. Stay away from deep woods. But above all else-

NEVER TRUST ANYONE WHO WASN'T HUMAN.

They were all bad and will try to trick you. Don't trust a single one. Do not engage. Like clockwork you've always taken them to heart. Always looking over your shoulder. Keeping your guard up. Keeping a dagger on you at all times. Never going out at night for any reason. You weren't gonna be carried away by some lovestruck creature! It helped a bit that you loved in the middle of town and rarely went into the woods for any reason. 

"It's an excellent choice. These flowers are very beautiful. I'm sure your service will be beautiful." Your eyes finally turned away from the sight. Your sweeping resuming as your boss politely escorted the couple to the door. "Don't worry about the delivery. It's on the house. ...You both have my up most condolences." She bowed one last time to the retreating couple.

A sigh escaping from your lips. "It happened again..Why does this happen so much?"

"Because there are creatures who have become so fascinated by the easy prey of our kind. A human is seen as a trophy of sorts. A thing to show off what you have but others can't have..." The old woman slowly closed the door. "We must remember that as humans, there are those who will hunt us."...Old black eyes turned to yours. "You're a young, beautiful woman. Possibly the most beautiful woman in town now. I wouldn't forget to be careful during these times."

"Don't worry. I'm not allowing myself to be trapped by anything."

Listen, KNY Mermaid/Pirate AU but the men are the mermaids and the women are the pirates --

Edit: Giyuu got saved yay

Wow y'all really like KNY Mermaid AU, huh.

(Giyuu is saved! Thanks to Tanjirou and Kanao stumbling into Shinobu throwing seasoning on Giyuu and persuades her enough to let the poor merman go. Shinobu is salty, Giyuu is bewildered but will take revenge later and then they become friends somehow)

I am thinking of doing mermen Kyojuro and Akaza later (along with Koyuki whom has Akaza tailing her around like a protective puppy) but I am not sure what fish Kyojuro will be based off. I have a few options but if you guys have any ideas, you can comment.

I am thinking of having Akaza's design based off Betta fish cause they're colourful and they're also called Siamese Fighting Fish. (But if you guys have any ideas, comment)

Yet again with some info of Mermaid/Pirates AU [Masterlist]

(Forgot to mention this) The Butterfly Pirates are easy to spot with their signature butterfly hairclips. Even if they occasionally don't wear it, their faces are recognizable in the bounty papers.

Merman Akaza makes an appearance with an unconscious Koyuki in his arms! The Butterfly Pirates are wary and surprised, but they are willing to lend a helping hand.

Lionfish based merman Kyojuro and Betta fish based Akaza! (Ft Inosuke the same fish as Akaza but he has split/double tail while Akaza has crowntail)

Edit (tagging those people that first wanted to see merman Kyojuro): @raccoonkumi , @mirrorcatcreditcard , @askcookieanon

are you able to do more of the kny pirate au? I really like the concept of it :3

(Someone asks about Mitsuri and I accidentally deleted it 🥹)

In this AU, Mitsuri is a barmaid and yes, Obanai is a merman :)

An old unfinished drawing that I've left for so long lol

Mitsuri comes back with a generous amount of fruits but no one is there when she returns.

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✯⁠)

Instead of a bounty plastered, this time, the merman noticed, the pirate had her face over a large poster, hung almost neatly just by the ship dock. He stayed hidden, still hearing footsteps and chattering echoing through the small port belonging to a small island he had just came across on.

He heard, despite the slurring words of those drunken humans, that the island is under the protection of the Butterfly Pirates ever since those -- what the government branded as criminals -- saved the natives of the island from nasty illness that had reduced the number of their populations. The government had deemed the islanders a 'loss cause' and abandoned them in time of needs. The pirates had saved them and the islanders were so grateful they even propped a picture of the captain by the dock.

He emerged out of his hidden spot once the coast was clear, propping his arms over the dock configuration, careful not to make loud splashing in the water as his eyes darted towards the taken picture of the Butterfly Pirates captain.

Gentle looking, her eyes were, even in the form of a picture. Unlike her bounty poster, she had her mouth opened in this one, the corner of her lips tucking up as if she was almost laughing while the photo was taken. It didn't matter what she wore in this poster or her bounty one, she could have worn a rug and still looked beautiful in it.

He tilted his head, eyes never left the poster, remembering the way this particular captain looked at him with no trace of judgement, eyes twinkling with no hostility and leaving him be in peace when he didn't reply when she greeted him.

" My, aren't you the prettiest merman I have ever laid my eyes on. "

He shuddered, feeling heat creeping up to his cheeks and ears as he recalled her sweet tone voice. Shaking his head, the merman dived back into the water, deciding that, while his dislike for humans still remained, it doesn't apply for this pirate with the name Kanae.

can you show us any giyushino art or something that includes them you have been doing lately

i miss them

I missed them too

Masterlist

I am still trying to decide why at the time Shinobu tried to roast him. One idea consists of Giyuu unintentionally jumpscared Shinobu when he emerged from the water and she dropkick him into unconsciousness before tying him up in an attempt to scare him.

More merpeople AU

Masterlist

Kanae gets injured and Akaza has an idea on who the culprit is.
