Demon Slayer AU Where Everything Is The Same Except Yoriichi Is A Ghost.

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 :)
