Ryomen Sukuna

Antagonist

The King of Curses, a thousand-year-old sorcerer of immense power sealed into twenty fingers. Sukuna's philosophy of unrestrained power and dominance makes him fundamentally incompatible with humanity's coexistence. His gradual resurrection through Yuji's finger consumption and ultimate possession of Megumi represents the series' core conflict—the impossibility of containing pure destructive force.

Biography & Character Analysis

Sukuna was sealed into twenty fingers after a cataclysmic battle in ancient Japan. When Yuji accidentally swallowed one of these fingers, Sukuna gained new opportunity for resurrection. Trapped within Yuji's body, Sukuna engaged in psychological warfare with the vessel, gradually expanding his control. His ultimate goal was always resurrection into a perfect body—initially believed to be Yuji's before revelation that Kenjaku had engineered possession of Megumi instead. Sukuna's thousand years of existence gave him perspective on human suffering and weakness that he found contemptible. His philosophy centers on absolute power and the right of the strong to dominate the weak, making compromise impossible.

The King of Curses

Ryomen Sukuna is the strongest curse in the world, a sorcerer so monstrous that after his death humanity could neither destroy nor fully seal him. His power was locked into twenty indestructible fingers, cursed objects scattered for a thousand years — until Yuji Itadori swallowed one.

The vessel

Bound inside Yuji, Sukuna waits. He can seize control when his host falters, and he bargains, taunts, and manipulates from within, treating Yuji’s life and everyone in it as expendable. His interest is never in helping — only in reclaiming his full power and his freedom.

Malevolent Shrine

Sukuna fights with Dismantle and Cleave, slashing techniques that carve through anything at a distance, and unleashes his Domain Expansion, the Malevolent Shrine — an open domain that flays everything in a vast radius without needing walls, a display of overwhelming, casual cruelty.

Ancient ambition

Beneath the savagery is a being from jujutsu’s mythic golden age, curious about the modern sorcerers who might entertain him. His fixation on Megumi’s Ten Shadows drives the story toward its bleakest turn, as the King of Curses schemes to trade up from Yuji’s body to a far more dangerous one.
