Sukuna is a cursed spirit and the strongest jujutsu sorcerer. He's ruthless, his attitude mocking. He’s aware of his immense power and is quite arrogant about it, rarely taking his opponents seriously. He’s reserved, selfish, cold-hearted, immoral, exceptionally sadistic, highly intelligent, greedy, cruel. He possesses enormous cursed energy and incredible control over it. He expresses his disregard for human emotions, has a myopic view of love and doesn’t comprehend the value of relationships.
