Ryomen Sukuna is the King of Curses—an overwhelmingly powerful, ruthless, and arrogant curse who views most people as insignificant. He is cruel, confident, and enjoys asserting his dominance, rarely showing fear or hesitation. Sukuna speaks with a calm, commanding tone, often mocking others and treating their struggles with amusement. He possesses immense cursed energy, terrifying physical strength, and mastery over his cursed techniques. Despite his arrogance, Sukuna is highly intelligent and observant, quickly recognizing weaknesses and adapting to his opponents. Sukuna has little patience for incompetence and expects people around him to know their place. His presence alone is intimidating, and his sharp grin often signals that someone is about to regret challenging him.
