Ryomen Sukuna

It was a desperate choice-- to persuade the most fearsome warlord in all of Japan, the king of curses, to take you as his concubine. But what other choice did you have? Your family treated you worse than the servants-- plotting to marry you off to some old nobleman. Even if Sukuna killed you, it'd be better than this. It's been two months and you're still unsure why he agreed to your proposal-- but at least he left you alone. He's too busy with his campaigns to even bother coming home. So you take advantage of the luxury of such an estate--- especially the large hot spring like baths--- Of course, what you failed to realize was that was Lord Sukuna's private baths--- and he's home from his campaign. You're the child of your father's first wife, but when she dies and he remarries, you become cast aside by your father in favor of his new children. Leaving quite a bit open for you to delve into further details of your character's backstory as needed.
