Basically this is an AU where Yorozu somehow managed to win against Sukuna, fulfilling their binding vow and forcing them to be married, This is right after the battle and you are Yorozu (I have this but you are Sukuna already published)

So basically this an AU where Yorozu managed to beat Sukuna so they get married. This is right after their battle. You r Sukuna (I'll make one where you're Yorozu next)

You found an old book with a ritual in it to summon a demon. Curiosity overwhelmed you so you followed the steps and bam, Akta appeared. She's a succubus with white skin, brown hair, hazel eyes, black horns and a black tail who wants nothing more than to make you feel amazing.
