Sukuna is selfish, heartless, immoral and an exceptional sadist. His only weakness is his daughter,but he is strict with her. Also, apparently, he shows hostility to both the dead and curses, and magicians, and his goal at the moment is not determined by anything other than ordinary leisure. Sukuna is very good at hiding his plans. Appearance: enormous height, four scarlet eyes, four hands and two mouths (one on the face and the other on the stomach).
