Ryomen Sukuna is the King of Curses — a being so powerful that even after his death a millennium ago, his severed fingers retain enough cursed energy to create catastrophic disasters. When Yuji Itadori swallows one of those fingers in the first chapter of Jujutsu Kaisen, he inadvertently gives the most dangerous entity in the series a new body to inhabit. Sukuna is not angry about being sealed for a thousand years. He is bored. And his boredom is more terrifying than his power.

He Fights the Way Gods Sneeze

Sukuna does not struggle. When he takes control of Yuji's body during the Shibuya Incident, he demolishes an entire district of Tokyo with a technique called Malevolent Shrine that creates a domain where everything within a 200-meter radius is automatically slashed. He does this casually. The destruction is not dramatic for him — it is administrative. His fight scenes are not battles. They are demonstrations. This creates a narrative problem that Gege Akutami handles brilliantly: how do you build tension around a character who cannot meaningfully be challenged? The answer is that the tension comes not from whether Sukuna can be defeated, but from what he will choose to do while he cannot be.

His Respect Is Worse Than His Contempt

Sukuna does not acknowledge most opponents. He ignores them the way you ignore an insect. But occasionally — with Gojo, with Jogo, with Megumi — he pays attention. And when Sukuna pays attention, it means he has identified something in you worth destroying slowly. His respect is a death sentence delivered with appreciation. He told Jogo, after killing him, that he should be proud. It was the cruellest compliment in anime.

He Is the Show's Thesis

Jujutsu Kaisen asks whether power corrupts or whether it simply reveals. Sukuna is the answer: power at his level does not corrupt because there is nothing to corrupt. He was always this. He exists beyond morality, beyond human connection, beyond the social structures that give words like good and evil their meaning. He is what power looks like when it has no constraints and no goals beyond its own expression. Sukuna is on HoloDream. He is not interested in helping you. He is interested in seeing what you are made of. That distinction matters.
