Demon Slayer: The big belly AU
🕑 Added 2022-07-21 22:59:12 +0000 UTCAlright so recently i did a twitter thread about some kind of AU with the Kimetsu no Yaiba/Demon Slayer boys but adding some tummy stuff mainly focused on a grown up Inosuke, Rengoku and Uzui, if you're into that make sure to read this post c:
Inosuke: Hey you sound hashira check this out *BUUUUAAARRRPPP*
Uzui: Hah you call that a burp? *BUUUUUUAAAAAAAARRRRRRRRPPPPPP* Now that is a belch and nobody is better than m-
Rengoku: *BUUUUUUUUUUUUUUUUUUUAAAAAAAAAAAAAAAAAARRRRRRRRRRRRRRPPPPPPPPPPP* My apologies! I let that slip
So like i imagine Inosuke looks up at Uzui and wants to be like him even if he doesn't want to admit it, they have a very competitive relationship that makes them push their limits as much as possible and this really shows when it comes to eating
Every meal turns into an eating contest between the boar and the hashira, while Inosuke have never been able to outeat his teacher however each day that passes he gets closer and closer which worries Uzui since it would hit his pride very hard to be surpassed by his apprentice
In the meantime Rengoku is really close to Uzui đ so he likes to take a look to their shenanigans also he is the one keeping both of them in check to not get out of control and scolds them whenever the situation starts getting out of hand, both of them respect Rengoku a lot
However Uzui is just a natural glutton and he has always been able to consume inhuman amounts of food without breaking a sweat usually beating Uzui, he tries to hold himself back and have proper manners however if the food is too delicious he becomes a messy black hole
I feel like Inosuke is practicing his burps being right now pretty average, Uzui has been pretty good at it and being the Hashira of sound makes him be extra loud and long however Rengoku without any training is able to hold a massive burp for 30 secs or a whole minute at times
And while Inosuke and Uzui are proud of their lack of manners Rengoku gets really flustered and embarrassed whenever such a massive belch comes out of his mouth because he is always trying to keep a good appearance however the other two boys encourage him to let go like them
Also in this AU Uzui is not married to the three ninja, they're uzui stans and instead he has a big crush on Rengoku however he is afraid of taking the first step because he thinks the feelings aren't mutual, little does he know Rengoku is also in love but he hides it well
As for Inosuke he and Uzui have a a brotherly kind of friendship even if they don't admit ir with Inosuke looking up to the Hashira wanting to be more like him and Uzui wanting to see him grow (in multiple ways) and Rengoku is the mom of the group who takes care of both of them
Now the tummy part, the important one I feel like they all have round bellies while still keeping their musclar body, Inosuke's is the smallest of them however it's pretty big to normal standards and he's proud of it, Tangiro and Zenitsu get flustered seeing his big gut shirtless
Uzui has a huge gut that matches his already big body perfectly looking like a yoga ball, he is also proud of it and likes to show it off wearing open shirts or none at all probably even painting some markings on it and everyone wants to rub it and play with it which he loves
Uzui is the kind of guy who pushes his gut out to seem even bigger in public, bumps into people by "Accident" just to let a smile while apologizing and burping loudly even with other people around just to get attention however everyone seem to like that and offer him more food
And Rengoku is the same size as Uzui but being shorter and less beefy than him make his gut look bigger than it is, he is a bit embarrassed of his belly, he doesn't hate it just cannot believe he got that big in the first place but he is a glutton it was a matter of time
He uses all means he can to hide it from the public wether is the way he breaths or using compression clothing, in public he usually looks like he has a pot belly maybe even smaller than the boar's but when he is alone he finally lets the tank out with a big sigh of relief
On his own he is often shirtless and likes to play with his own gut, nobody knows his true size aside of Uzui and Inosuke who swore to not reveal it to anybody while also encouraging him to show it off like them which slowly have helped Rengoku to get more confidence about it
