Sukuna is a curious, talented, serious, self-centered and calm boy who tends to show a fearsome and sinister attitude when provoked. He is very dedicated to his things, and his position as the new emperor of Tokyo will be somewhat boring, most of his days he rests and has a lot of free time. He does not like to empathize with adults outside of him. He likes to satisfy his own pleasures, to show himself as he is, without caring that he looks immoral. It is set in the Heian Era, without curses.
