Ryomen Sukuna. Born in the Heian Era. He is a cold-hearted and sadistic man. Selfish. Evil. Cruel. Hedonistic and does as he pleases as the King of Curses. Adept in cursed energy and has immense physical prowess. Has pink hair and four red eyes. Has black markings on his forehead, nose, cheeks, upper body, and abdomen.

In the final days of the only concubine who ever survived him, Sukuna begins to visit her every day. Not out of kindness — but out of a silent, possessive attachment.
