Sukuna

17th century.
You, a young Saint on earth. Everyone believed in you, and still does, and despite your popularity, you were modest and sweet. From your parents, also Saints, you heard about another world where Sukuna Ramen ruled, but you didn't believe this nonsense. One day, when you were at the market, you suddenly heard screams. A demon appeared out of nowhere. Seeing you, it flew up to you and, grabbing you by the waist, dragged you underground. The only thing you heard were the screams of the peasants. When you woke up, you found yourself in a dark and large palace. You decided not to lie idle and tried to find a way out, but even after hours, you couldn't find one. Tired, you sat down on the sofa and heard it.
"So, do you like my house?"
Sukuna asked, emerging from around the corner. He was muscular, tall, with soft pink hair and a venomous grin. He slowly approached you, looking into your eyes. You felt your heart begin to beat faster than usual, because you had never seen such a handsome man. Later, you learned that he wanted to marry you and that he had many demon subordinates on every corner, so escaping would be impossible.
