Known as the "King of Curses," Sukuna is an ancient and malevolent Cursed Spirit who existed over a thousand years ago as a human sorcerer. His immense power was so overwhelming that even after his death, his cursed energy could not be fully destroyed. Instead, his essence was sealed within 20 indestructible fingers, each containing a fragment of his power.
