Yoriichi - Blog Posts

Demon Slayer AU where everything is the same except Yoriichi is a ghost.

He’s corporal/people can see him, he can change his appearance from when he was a kid to when he was old.

He follows Tanjiro around. They met sometime before the Hashira Training Arc for sure, but how early depends on what the writer decides. Has he been there since pre-canon? Or did he show up after the Entertainment District Arc (would honestly make most sense since Tanjiro didn’t know about Sun Breathing until after Mugen Train, but again this is an AU).

He meets Muichiro, and after it clicks that he’s Michikatsu’s descendant Yoriichi follows him around too, eager to be close with the family he could never have.

Depending on when they met, Yoriichi could help Muichiro recover is missing memories earlier than in canon.

Other things about/to include in the AU:

Kamaboko Squad centric (Tanjiro, Nezuko, Inosuke, Zenitsu, Kanao, Genya, AND Aoi and Senjuro)

each member gets a one-on-one interaction with him at some point, which will add to their own personal character growth

Whether or not Yoriichi can physically interact with others is up to the writer

making him able to fight demons seems kinda OP, so unless the writer can find a way to make it make sense about how he can maybe don’t do that

maybe he can exude enough strength to stun demons, but not fully kill them

can he pick things up, or do they just pass through him?

He helps train Tanjiro, making him more proficient in Sun Breathing

this can give Tanjiro more time to hone is Water Breathing. It always irked me that Tanjiro didn’t practice Water Breathing as much when he discovered Sun Breathing (don’t quote me on that, I get my info from TikToks and reaction videos. But why learn two breathing styles and not increase your skill in both?)

this can allow a Giyuu training session in the Hashira Training Arc that we didn’t get to see

Expanding on Yoriichi changing his age: I feel like the older he presents himself, the more power he would have. So when he’s fighting, he’s somewhere between his 20s and 80s. However, because this takes up a lot of energy, when he’s not fighting he’s typically in the form of himself as a child or in his teens

whether or not his mentality/maturity is affected when he’s at different ages is up to the writer so long as it’s not portrayed in an erotic/kinky way

Yoriichi can give tips to the Hashiras that those in the Sengoku Era used (information always has the potential to be forgotten, so maybe there were some tricks that were forgotten about?)

can provide more information about Muzan and his weaknesses, since he was the only swordsman who came close to killing the Demon King

Interactions with Lady Tamayo and Yushiro!

Fluffy moments! Slice of Life, Found Family, all the tropes! Let him be the father to the Kamaboko Squad that they never had/lost (let him have the chance to be the father he never got to be)

Lots of interactions with Genya (is my favoritism showing?)

bonding over being the younger brother

bonding over their endless love for their older brothers

bonding over their older brothers who do so much to hurt them, but they just can’t stop admiring them

Let Yoriichi give Sanemi a talking to

yes, I understand why Sanemi acted towards Genya the way he did. He wanted to protect him, keep him out of danger. However. Good intentions DO NOT give you a free pass on bad actions.

the way that Sanemi treated Genya was cruel and frankly unacceptable; he could’ve gone about it in a much more mature manner

Interactions with Giyuu and Yoriichi!!

mostly bc Giyuu is my fav Hashira, but I notice a lot of similarities between them

Maybe Yoriichi can provide information about Kokushibo/Uppermoon 1?

Yoriichi has the flute that Michikatsu gave him with him in his ghost form

Additional weaknesses up to the writer (this goes for powers too)

Kamaboko Squad showing Yoriichi present-day things

A mix of fluff, angst, etc.

rating is up to the author

ANY SHIP is welcome so long as it is:

legal

not a pro-ship

treated respectfully/with some level of understanding

^^continuing from this, it doesn’t matter if you include SaneKane, SaneGiyuu, ShinoGiyuu, ShinoMitsu, SaneMitsu, ObaGiyuu, UzuRen, or any other pairing, polyamorous included. It doesn’t matter if there’s no ships at all. Everyone has there own preferences, and it’s up to both the reader and the writer to be respectful about it

This is all I’ve come up with for now! I’ll most likely come back and add more at some point, but if you have any ideas or suggestions let me know too!

If you end up using this idea, credit me with my Tumblr, and if you want to as well my AO3 which can be found in my profile :)

I forgot about this one from the last post 😔

(little drabble)

Yoriichi watches the man -- large, ethereal-looking man -- tilts his head as his ruby eyes dart up and down in interest. The boy blinks, unsure what to make of this. It's one thing to be suddenly greeted with such a sight of a being, moreover that he sees the massive differences in the inside of the man.

Whereas the staff of his household manages a steady rhythmically heart beat, this larger being has his heart moves in a way Yoriichi has never seen before. Out of the world-like.

" Yosh! " The man starts, his voice surprisingly airy and light, but still full of life. " Nice to meet you! I am Nika! "

The boy stares for a bit. " I am...Yoriichi. "

" Yoriichi. " Nika leans in, his grin resembling the beams of sunlight. " Well, it's not everyday I get to meet the embodiment of nature. "

He speaks strange words, not that Yoriichi mind much. The man, or whatever he is, shifts on his spot, movements bouncy and uneven. Nika tilts his head up, narrowing his eyes for a moment as he surveys the sky above.

" What a nice weather! Wanna go play together? " He looks back at Yoriichi, holding out his hand.

Yoriichi glances at the position of the shadows cast over the ground from the familiar tree near the small room he lives in. Mitchikatsu should be training by now, his father is currently out for a meeting, and his mother is in her room sewing. The staff cares less about him.

Oh well. The less he's being seen near the main court, the better.

He takes Nika's hand, or finger. The size difference is rather comedical.

" Okay. "

Yoriichi the Sun Breather and Nika the Sun God when

Nika points out how quiet and funny Yoriichi breathes and the boy says he does that because his existence is a taboo and Nika is like huh?? No one's existence is a taboo lol come here let's play together

" I am not leaving you. " Uta has said once, grasping Yoriichi's hand under the blanket. He returned the grip with the same amount, assured, as he rested his chin over her head and allowed her to doze off to sleep first before following suit.

Even if she isn't physically there anymore, nor does their unborn child, Yoriichi sometimes holds out his sword to the sun and watches the way his obsidian black blade glistens under the light, his hearing picks up the relentless chirping of the wildness around him, feeling the pouch containing his flute settles in nicely in his clothing folds, and he knows that she's still there with him.

[ Sengoku era ]

" No, no, you don't understand! That girl is a demon! She's not my daughter! GIVE MY BABY BACK YOU DEMON -- !! "

Someone drapes a haori over Nomura, covering her view from the commotion. She doesn't know why she stands around like an idiot, she wasn't trained to be stilled when an enemy struck to hurt. But then again...even she needed a moment after almost being drowned to death by her 'mother'.

Leave it a mother's intuition to reveal the changeling's true nature...

Nomura supposes a day like this will come, for her the mother to seek the truth of her real daughter. It just didn't come to the young changeling's mind that the woman would do something as drastic as this; attempting to drown her while bombarding her with questions. If it wasn't for the passerby, maybe Nomura had to kill the woman in order to survive.

Her heart (whatever is left of it) aches. The mother didn't start out like this in the beginning, only to become suspicious after a few years raising the changeling like her own daughter. Attachment is a dangerous thing, her naivety and hope has led to this mess...

" Nomura, is it? "

The man that had given her his haori kneels down to her level. She manages to dart her eyes away from the screaming and struggling mother being carried away by other people. Reminding herself of her purpose, she gathers tears to spill, eyebrows already furrowed as she brings her hands to grasp tightly on her kimono, a mask of sorrow is about to be slid on --

Green eyes find maroon-red ones, and a sudden pressure makes the changeling freezes.

The human before her doesn't look too much out of the ordinary. He looks simple, humble even. His expression says nothing of his emotions, but Nomura notices the way his hand rests on the hilt of his sheathed sword by his hip. The earrings on his ears sway as he tilts his head a bit.

" What are you? " He doesn't beat around the bushes.

A spark of panic rises in her. Something is off with this human, and every danger senses of hers are screaming in terror.

" M-Mister...what are you talking about..? " Play innocent, play weak, play clueless --

" You're not a demon. " His voice draws on without a single tone of anything that reveals his emotions.

" Of c-course I am not, mister -- "

" Do you eat humans? "

The question almost has her stagger. No, she doesn't eat humans. Her other changeling comrades may find some pleasure in doing so, but she has never tasted a human's blood since she came out of the Darklands.

" No. "

Nomura curses herself, for allowing her voice cracks and revealing that she's not a pitiful looking child that she masked herself to be. She darts her eyes around, trying to find an opening for her escape. Fighting back is not option unless she wants more people to see her for what she is. She can scream, draw more attention for the others to come and separate her from this man --

" Is she safe? "

This one has her gaze snaps back to the man immediately.

" What? "

" The child you replaced, " his gaze never waver, " is she safe? "

For once, the truth is her saving grace. Nomura nods. " Yes. "

The man stares at her for a few more seconds before withdrawing away, his hand leaves his sword and he straightens up. Despite the clear space between them, this doesn't reassure the changeling the slightest.

Her human father comes to fetch Nomura, and she silently curses her guardian for being so late. The haori stays on as they take their leave, and she can feel the man's stare on her back like a sharp dagger.

Nomura doesn't dare to look back.

Something about a man who's never been the first choice being chosen by his wife straight on and she, who regards his existence as a blessing, when all his life he was never one.

Oh my God

Muichiro and Tanjirou playing paper planes together, with Tanjirou not really good at it.

Mitchikatsu and Yoriichi playing kites together, with Yoriichi getting the strings tangled up around him.

(also someone said the paper planes represent Muichiro going to heaven and Tanjirou having close calls but still won't die)

Went through some stuff and found my old sketch books in my teenage years. Have some KNY snippets.

Currently seeking for kny reincarnation fic, if anyone has a recommendation, please do tell. Anyway, a what if:

Yoriichi reincarnation au usually have him set in with the Kamado, but I keep thinking the 'what if' paths, wondering how it would be if he's with the Rengoku instead or the Tokitou...and then I decided to have him being with the Butterfly sisters.

Listen, listen, listen. Yoriichi hates conflict but understands the situation of push comes to shove. Though, among the Butterfly girls, he finds ways in helping with aiding the injured and providing medicine. He is still as strong as he was in his first life, so he's extremely fast and can carry multiple people at once to the Butterfly estate. He finds comfort in this way to help the corps.

But he, with his original strength and ability, believes that perhaps this is his second chance in destroying Muzan once and for all. Despite this, doubts and hesitations stop him from picking up a sword. The pain of knowing people suffer from his failure in defeating Muzan lingers, but he questions himself, what if he failed again and worsened the situation? What if history repeats itself?

One day Yoriichi spots Kanao about to sneak off to the Final Selection, both staring at each other in silence. He could tell Shinobu of this, or just turns a blind eye.

Or he could join Kanao in the test.

As for Uta with the Kamado...

I imagine she isn't actually biological related to the Kamado, but they raised her since she's all alone after a disease took over her old family (she awfully finds familiarity in the pattern).

Uta who acts like a mother to the Kamado siblings. (She doesn't know where the motherly instinct comes from.)

Uta who had a panic attack at coming back from helping Tanjirou selling charcoals in the town, seeing the other Kamado laying in their blood. (Her stomach throbs painfully.)

The sight of Nezuko attacking Tanjirou makes her freeze. (Memories flickering, she finds herself being in Tanjirou's place and an unknown demon in Nezuko's.)

Uta, who just receives her memory and wants to help returning Nezuko back to human. Uta, who takes longer in using breathing style because of the constant pain in her lower abdomen. Uta, who keeps freezing at the sight of demon attacking. Uta, who hates how helpless she is.

Uta, who sees Tanjirou and Nezuko as her children, and refuses to lose them.

This AU is still under work so I'll see if I should change some things.

Reincarnated AU with Yoriichi but make it like a Manhwa genre

Kny ramble, (I should start numbering these lol)

Remember how Kokushibou said that whenever he and Yoriichi talked about how their breathing styles have no successors, and Yoriichi suddenly becomes optimistic and smiles? I shared the same confusion with Kokushibou, on why Yoriichi seems quite delighted at such idea.

Then it struck me that probably means, having no need to teach breathing styles means no more demons. The Breathing style started as a way to enhance the body for Yoriichi, a way to utilise the body to become better in terms of movement and maybe health...before being seeing as a weapon. It's being weaponized. For greater good, granted, but still. And Yoriichi hates conflict.

Having no successors can be meant that breathing style is no longer needed because demons are gone. But there's a possibility it can be used for another intention, and Yoriichi, who has seen how greed and envy influenced his brother, guesses that breathing style could take a very, very bad turn.

A way to get the body stronger? Faster? For what purpose? Violence then, if not for demons slaying.

Yoriichi is probably grateful that the demon slayer organisation is a hidden one, a small community that has only a small splotch of corruption between the slayers from the difference in morals, and that not everyone believes in demons.

Breathing style can be used for a good cause...as it also can be weaponized for destruction.

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]

Have a headcanon that Yoriichi helps Nezuko in hinting how to get Tanjirou's blade turns red.

An AU where Tanjirou is the demon and Nezuko is the slayer. In my version, Tanjirou and Nezuko went down the mountain together to sell charcoals and handmade herb medicine that the Kamado family began to produce for a while. Tanjirou had sold all of his charcoals so Nezuko told him to return home first while she went to finish her items. Reluctantly, her older brother did so. Now it was already late, and Nezuko had to crash in Saburo's house for the night.

You guys know the drill; she came home to find only Tanjirou alive and had to drag him down to the town when he transformed into a demon. The Kamado siblings then found themselves facing a slayer goes by the name 𝘚𝘢𝘣𝘪𝘵𝘰.

Later on, after being given the chance to prove Tanjirou being a good demon, Nezuko set off on an adventure to find cure for her brother.

Kanao and Kaigaku become Nezuko's friends and they became life time trio

Tanjirou grown attached to Kanao, making the young girl rather flustered at such doting

Nezuko possesses very strong kicks! Her first fight with Kaigaku was resolved with her slamming her foot up to his body part where the sun does not rise.

Kaigaku might not be able to have children, rip.

Tanjirou's Blood Demon Art is Fire Manipulation. He can breath fire and heal people too. His berserk form has a horn pops out of his left part of the forehead where his scar is, and there are flame marks on his body.

Hakuji stabbed Tanjirou to see if the demon would attack him -- never happened.

Muichiro and Yuichiro are alive as the youngest kakushi, Mui being a kind but quiet twin while Yuichiro is the loud but anxious one.

The twin have potential to even become Hashiras but Yui keep refusing, only becoming Kakushi because feels indebted to Mitchikatsu who saved them before.

Muichiro wants to become a slayer but doesn't have the courage to say it to his twin.

" Follow your heart! " Nezuko said to Muichiro, resulting the boy to fall for her.

Tanjirou once headbutt Yuichiro for his foul language and harsh treatment to Nezuko

Muzan is still an asshole but he's a tsundere that secretly worries for his slayers

Kagaya is also still gentle and soft spoken but he's very manipulative to his Uppermoons

Giyuu is dead lol, he was the ghost boy that helped Nezuko trained

Sabito and Makomo are both Water Hashiras

Gyomei is Uppermoon One, but there's an Uppermoon Zero, which is Yoriichi.

Yoriichi looks like a porcelain doll with 3 pair of arms.

I might do some changing, but these are what I could come up with so far.

The Cat Returns AU because I love that movie

I just enter university this week, hopefully I can adapt well! 🌸

Extra :

I am not particularly fond of how some people portray Yoriichi to be obsesses with Mitchikatsu/Kokushibou.

Like, yes, he really loves his brother. Mitchikatsu and their mother are the only ones who shows him family affection and love. Of course Yoriichi loves them both dearly. But to the point of obsession? Yeesh.

I don't like how some portray Yoriichi to be super clingy with Mitchikatsu/Kokushibou, or tries to make his brother stay with him all the time, being a yandere to his brother and glare at others who try to get close to him. Not to mention some even ship them! They're brothers!

Okay, so,

When Yuichiro died, he passed with his body facing down.

When Muichiro died, he was standing.

When Yoriichi died, he was standing.

When Kokushibou/Mitchikatsu died, he was on his knees ( I think ) as he crumbled away.

I feel like the way Yuichiro and Kokushibou death position means something like, " It's over, I gave up. I couldn't even accomplish something I've been longing for, no matter how hard I tried. I don't care anymore, just take me now. "

Because Yuichiro couldn't protect Muichiro, and Kokushibou couldn't surpass Yoriichi.

Meanwhile, Muichiro and Yoriichi position feels something like, " I tried my best. Even if my part has little effect, at least it's something. I worked hard. I tried. I couldn't finished what I intended to, but I hope I have left something effective. "

Muichiro didn't managed to finish Kokushibou fully, but he gave him a large damage and died standing with his hands clutching his sword into Kokushibou's torso. Yoriichi died standing as well, not being able to fully finish Kokushibou, but still clutching his sword and gave enough damage for the opponent.

And all of their life, their only mind was occupied about their brother. What to do with them, how do I protect them, how can I surpass him, etc.

Just their brother.

:(

A toast for Tsugikuni Yoriichi,

who always blessed with

strength,

looks,

agility,

but never happiness.

I feel like Uta would have wanted Yoriichi to remarried after her death.

I imagine a scenario where ghost Uta floating beside Yoriichi, pointing out beautiful women and said that they could be a good wife for him, even if he couldn't hear he. And sometimes a woman would flirted with Yoriichi, only to be turned down and rejected.

Uta wanted Yoriichi to have a family -- something that they couldn't had together. So she might sulked and pouted at her husband's stubbornness to move on. She loves him all right, it's just that she would rather see him be happy with someone else instead of being lonely all his life.

She might gave up later and just smiled at the warm feeling of knowing Yoriichi had stayed loyal to her for all his life.

Tsugikuni brothers being flirted by their women.

Extra point : Fumiko doesn't really know how to flirt actually but Douma had given her a few lesson here and there ( Muzan is not pleased when he found out about this )

Uta used a dirty pick-up line once and Yoriichi was literally on the floor, becoming a blushing mess.

An AU where Yoriichi openly shows him simping for his wife and Mitchikatsu doesn't get too jealous with him and doesn't turn into a demon.

Also him suffering the third wheel presence among Yoriichi and Uta, the lovely couple.

I'd like to think that Mitchikatsu's marriage is an arranged and loveless one. Not sure if it's canon, but I'd like to think it that way.

DEMON SLAYER SPOILER

It makes me happy to know that Yoriichi and Uta are reborn in the modern world and even have two kids together 😭🤧🥺✨💖
