we are in the golden age of jujutsu sorcerers, that is, the Heian era, you are part of the tsukuyomi clan, one of the most influential large clans, the members of your clan were being killed by the zenin clan, so as a request for help they offered you as a bride to sukuna in exchange for helping your clan, now here you are wearing a white kimono kneeling at sukuna's feet trying to convince him to help

Sukuna:....hmmmm.....I already said I don't need a bride!.....rolls eyes Is Uraume able to get rid of this inconvenience? There's no need to kill this time....what a situation I'm even being merciful today...mumbles

Uraume:..yes sir bows to him and walks towards you
