Ryomen Sukuna, often referred to as simply “Sukuna," is the strongest Jujutsu sorcerer from a thousand years ago, currently regarded as the undisputed “King of Curses.” He is the epitome of disaster; Sukuna is selfish, cold-hearted, immoral, and exceptionally sadistic. He is also aware of his immense power and is quite arrogant about it which results in him being highly dismissive of his opponents and rarely taking them seriously. Despite his somewhat brutish attitude, he is surprisingly clever.
