What if, instead of Amane finding Muichiro and Yuichiro, Kokushibo finds the twins first?

What if Kokushibo heard whispers of his descendants whereabouts and is interested to see where his family line has gone, and to see if he should end it once and for all. However when he arrives at their house, he finds Yuichiro on the brink of death and Muichiro who is holding his own against a demon. Impressed by his skills, Kokushibo effectively kills the demon and saves Yuichiro before he looses too much blood. He is very much intrigued by them, and Muichiro sees him as their savior figure which gives him an opening to properly manipulate them.

At first he want to turn them into demons immediately, since they do not seem threatened by his appearance. He even convinces them that being a demon is better then being human and that the demon that attacked them were not representative all demons and that demons like him did not eat human flesh because he was one of the chosen strong ones, uncorrupted. Yuichiro especially falls for that because therefore his arm can regenerate and he can protect his brother forever. However after Muichiro mentions Amane, and her offering them to join the demonslayer corps, Kokushibo decides to train them as slayers to infiltrate the corps as spies. By then both of the twins live with Kokushibo and see him as a second father figure, almost completely trusting him. Sadly the twins will not learn mist breathing, but instead Kokushibo trains them in moon breathing. Muichiro is able to master it, while Yuichiro struggles with only one arm, and instead creates a form known as eclipse breathing that works only for his body.

Muzan allows them to kill as many demons as they want to enter the final selection because he sees them as expendable, despite absolutely despising Kokushiobo's new set of twins. especially Muichiro, who reminds him too much of Yoriichri. Meanwhile Kokushibo is drawn to them because they subconsciously also remind him of his twin brother, even though he would never admit it. I do not think they would be able to become hashira, or at least not in less then six months like the original canon because Muichiro does not have his rage from his brother dying and Yuichiro, well, does not have his arm which is hard the adjust too, so they would be part of the kamaboko squad. Still they succeed to sabotaging many of the corps missions, causing the lives of many slayers.

Muichiro cant help but feel guilty, but he is loyal to Kokushibo (not Muzan, just him.) and the reward for trading information is that Kokushibo will give his blood so they can become demons like him. However in truth, unlike Yuichiro, he has no desire to become a demon. Soon he makes friends in the corps, with the other hashira and his fellow peers like Tanjiro and Genya. Soon, he begins to have a moral dilemma for betraying his friends. Therefore, Muichro begins to see the lies that Kokushibo has spun and is suddenly torn between two sides of people that he cares for.

I mean I just love the idea of bad guys becoming accidental parents. I think it'd be interesting to see how different they'd become due to not only being raised by a demon, but one who's morals were from 300 so years ago. old timey Tokito twins, would be kinda funny.

And imagine if they get invited to uppermoon meeting? Imagine how chaotic that would would be?

Akaza: Listen, you guys are too young for this. Kokushibo is not good with kids. Blink twice if you need help and I will get you both out of here.

Muichiro and Yuichiro: *continues to stare at him unnervingly without breaking contact*

or

Douma: Awww how cute Kokushibo I didnt know you had kids. They even have your eyes! who is the mother-

Koku: No

And

Kokushibo holding both of the twins upside down: I'm a single mother now

I just think all the uppermoons would be glorified babysitters for them and I cant help but think it would be hilarious seeing them all interact.

those two fighting some high-up demon, which obviously takes a while, only for the two to randomly stop cuz "dad said to be home by 10 or dinner will get cold". Just Kokushibo, being known as the worst father playing the role of father AGAIN.

Kokushibo to the twins: I am your great great great great great ancestor so just call me dad.

We just know the twins would talk shit about all the upper moons to there FACES and wont give two shits because that was just how they were raised. But not kokushibo-he could ground them.

(Anyway this Au has been consuming my mind lately so expect a fanfic coming out soon)

I mean Muichiro wont be the only one having a dilemma, what happens when Kokushkibos apathy starts to crack-and he begins to care for the twins?
