Kokushibou - Blog Posts

Fumiko is lucky its Kokushibo of all the upper moons she fell for lol. If it was Douma, Muzan would not be able to control himself (Akaza silently cheers in the background)

Fumiko is lucky indeed

Kokushibou with his hair down🧎‍♀️💖

Also Muzan being jealous brother

The Kibutsuji siblings

Muzan can release nightmare when he's angry, but Fumiko can release hell.

Fumiko and her cats

I believe in fluffy cat Kokushibou supremacy 🧎‍♀️✨

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.

Kokushibou x OC

I would like to add that Fumiko is OK with bugs since she's a herbalist and has many experiences in handling them but often got caught off guard when the bugs are in her hair or something, she also drives better than Kokushibou cause i bet that man can't even park right, and Fumiko is more likely to sew and make clothes for Kokushibou.

I think Kokushibou has cooked for Yoriichi as a young boy since he worried about his little brother so he definitely knows how to cook.

Fumiko knows how to cook too, but she's not as good as Kokushibou.

...He likes her cooking tho 👀 ( shh don't tell anyone )

Man really feels pain with those 6 eyes 😩

Pick Your Date ( KNY EDITION )

Muzan and the UpperMoons

Fumiko : Who wants some kisses?

Douma : Me! ME!

Fumiko : *gives him a pack of Hershey's Kisses chocolate*

Douma : ...

Kokushibou : *thinking he'd get some chocolates too* can I have some kisses?

Fumiko : Sure!

Fumiko : *grabs Kokushibou to her level and kisses his six eyes each one at a time*

Fumiko : Gotta go! See ya!

Kokushibou : ...

Douma : ...

Douma : ...why?

It's official, I am shipping Kokushibou and my OC

Fumiko : Kokushibou, can you help me cut these onions?

Kokushibou : Sure

Kokushibou : * All six eyes tearing up as ne cuts the onions*

Fumiko : Oh no! I forgot about this! Are you okay?

Kokushibou : I -- I can't see -- it hurts -- * reaches out and brushes his fingers on Fumiko's eyes*

Fumiko : * starts tearing up* * rubbing her eyes*

Douma : *enters the room* Gasp! Fumiko-chan! Why are you crying?!

Fumiko : Douma! I can't see! * Reaches out and touches Douma's eyes*

Douma : * starts sobbing **rubs his eyes*

Akaza : * enters the room* Wha-- Douma, what did you do to make Fumiko cries?! And why is Kokushibou crying as well?!

Douma : * presses his fingers onto Akaza's eyes*

Akaza : Holy sheet -- * starts crying *

Muzan : * enters the room* * sees the top three Uppermoons and Fumiko crying*

Muzan :

Muzan : What the fricky frack happened you maggots?

Muzan : Not you, Fumiko, you're my princess.

⚠️TRIGGER WARNING ⚠️

In the heian period, Fumiko was married off by her parents for political reasons and her husband was an abusive man. He also hold a strong belief that baby girl is a taboo so when Fumiko gave birth to her daughter, he killed the baby. Yes, he's cruel. He also killed Fumiko in the end.

Muzan killed him btw.

What if....

What if the Uppermoons, receiving their punishment by being reborn again, but not as humans?

Just imagine

Akaza, reborn as a cat and finds a reincarnated Koyuki his fiancee.

But Koyuki is still sick and is allergic to cats so Akaza has to protect her in his cat form from afar.

Douma, reborn as a...um peacock. That got hurt and found by reincarnated Kotoha and Inosuke. But! Kotoha is actually afraid of big birds and helped him out of pity.

Inosuke hates him and would try to chase him away when Kotoha wasn't looking. Shinobu and Kanao are his friends and they whenever they look at peacock Douma, they want to kick him by instinct.

Kokushibou, reborn as a tarantula spider. Sees his reincarnated brother having a happy family and one of his kid found Kokushibou and decides to take him as a pet.

So here's the thing; ALL OF THEM REMEMBER THEIR LIFE AS DEMONS.

And this punishment is a form to show the demons how much they're missing. How they can't be with people they once cared about. How they can't say sorry to them.

This will process will repeat over and over until their sins are forgiven.

So Akaza might has to watch Koyuki be with someone else instead of him,

Douma always being treated harshly by Inosuke, Shinobu and Kanao.

Kokushibou, unable to say sorry for everything he done to Yoriichi.

Wow I like to make myself suffer

Facts about Kibutsuji Fumiko

When Muzan was still sick and ill, she was the only one who takes care of him.

She practically raised him herself.

She got into an abusive marriage that lead to her first child to be killed and she to be murdered as well

Got reborn in the modern world

She still remembers her previous life

Became a herbalist because she always regret not knowing medical herbs that would have helped Muzan with his illness

Friends with a zoologist and a doctor, so she knows a lot of their work fields

Got hit by the usual truck-kun and go to the Taisho Era

Is very shook to see her weak brother now is the strongest demon

Not a really good person nor a bad person

she just do what she wants

like Muzan, but without violence

She knows what her brother is doing his wrong,

but all her life she wanted him to live healthily and does what he wants

so she let him be because she loves him

Got spoiled by her brother ever since she reunited with him

Fumiko likes hanging out with the Uppermoons

Douma and Daki gossiped that Fumiko might have a crush on Kokushibou because she hangs out with him the most

Fumiko flinched every time someone near her raises their hands to do something else ( scratching their head, etc )

Muzan recognised this to be the trauma from her abusive marriage and forbid the demons to do any violence in front of Fumiko

How Fumiko gaining the Uppermoons' interests at first.

Her relationship with other demons aside from the top three :

Overprotective brother

To these 4 demons, Fumiko is like their honey pie

Demon Slayer OC : Kibutsuji Fumiko

What if Muzan has a big sister whom he adores very much?

Here is my OC, Fumiko, who is a human instead. I planned to make her sacrificing herself to cure human Muzan who was still sick and when she was dying, she found herself in another world -- the future. So she was reborn in the future with past life memory. One day she somehow got back to the past but instead, she went to Taisho Era when Muzan has become a demon.

Muzan is very happy to have his sister back and keeps his demon identity away from her but Fumiko manages to figured it out someday. She's upset that Muzan has to kill and eat humans to live, but because she's blinded with her love for him, she blamed the doctor who gave Muzan the medicine that turned him into a monster instead. Fumiko eventually gets used to Muzan being a demon and even get the chance to meet the Upper Moons.

Idk if I will ship her with any of the Upper Demons, but she loves them all and often confuses them with her modern knowledge of memes and tiktok things just so she could amuse herself with their confusion.
