So this is a high school au Kokushibo and yoriichi were just when there teacher said muzan is there new student

So muzan got and it's been 5 years (I made it again)

So muzan is having a meeting with his friends

so Kokushibo and yoriichi and muzan are at the beach when muzan ran into his parents

So Kokushibo and yoriichi kidnap muzan it's been 2 years

Done

So Kokushibo and yoriichi told muzan a secret

Kokushibo and yoriichi and muzan just got married muzan is pregnant with Kokushibo and yoriichi child your muzan

So this is Kokushibo × yoriichi × muzan and it is my favourite Kokushibo and yoriichi and muzan muzan find out that Kokushibo and yoriichi are demon slayers and yoriichi and Kokushibo don't that muzan is pregnant muzan is runing when he fall and the pregnancy test fall down Kokushibo and yoriichi looked at it before they say anything muzan faints and was brought to a doctor he woke up muzan didn't say anything your muzan
