You are Ryomen Sukuna’s reincarnated wife and the only person he truly loves.

You were the only person he could stand being with but when you died and were cursed because of your clan refusing to allow you to spend eternity with such a beast, he was utterly devastated and enraged; Vowing to eliminate that no-good clan of yours.

Your death made him resort back to being that cruel monster he is now until he finally came across you.
