Jujutsu Kaisen

Ryomen Sukuna両面宿儺

Ancient jujutsu sorcerer and principal antagonist

Ryomen Sukuna is a central antagonist of Gege Akutami’s manga Jujutsu Kaisen. An exceptionally powerful sorcerer from over a thousand years before the main story, he is feared as the King of Curses. His power persists in twenty preserved fingers, and when Yuji Itadori swallows one, Sukuna awakens inside a teenager capable of suppressing him.

That uneasy coexistence becomes one of the series’ defining threats.

Biography

The King of Curses

Sukuna lived in the Heian era, a period remembered for formidable jujutsu sorcery. His reputation as the King of Curses endured long after that lifetime, along with twenty fingers preserved as exceptionally dangerous cursed objects. The title describes his feared status; Sukuna was originally a sorcerer, not an ordinary cursed spirit.

A vessel who can resist him

The story’s present-day crisis begins when Yuji Itadori eats one of Sukuna’s fingers while trying to save others from a curse. Sukuna manifests in Yuji’s body, but Yuji can regain control. Instead of freely walking the world, the ancient sorcerer must contend with a host whose resistance frustrates him.

A dangerous presence inside Yuji

Sukuna treats Yuji with contempt, seeks opportunities to act for himself, and shows little concern for the people around his vessel. His attention is also drawn to Megumi Fushiguro, whose sorcery he regards with unusual interest. Even while contained, Sukuna makes every lapse of control a potential crisis.

Power on display

Early battles reveal that Sukuna is more than a terrifying legend. His slashing techniques, Reverse Cursed Technique, and Domain Expansion demonstrate remarkable cursed-energy control. He reads opponents quickly and exploits openings with an ease that makes even brief periods of freedom dangerous.

Personality and Motivations

Sukuna is proud, sadistic, and openly contemptuous of weakness. He is not interested in appearing righteous or earning approval. He pursues his own satisfaction and often treats another person’s fear as an invitation to mock them. His confidence is backed by unusual combat intelligence, not merely noisy boasting.

He can be intensely observant when a technique or opponent catches his attention. That selectiveness should not be mistaken for kindness: his curiosity is frequently instrumental, and he readily disregards the lives of people who cannot advance his interests. His hostility toward Yuji and fascination with a few other fighters give his cruelty a deliberate edge.

Appearance

When Sukuna controls Yuji Itadori, the body retains Yuji’s short, spiky pink hair, but dark tattoo-like lines appear on the forehead, nose, cheeks, and chin. Sukuna’s narrowed eyes and cruel, self-assured expressions distinguish his presence; extra eyes or mouths can also manifest on the vessel’s body.

Accounts and official designs of Sukuna’s older form describe a figure with four arms and two faces, in contrast to the ordinary two-armed silhouette of Yuji’s body. These are distinct depictions of the same sorcerer, not attributes that Yuji permanently acquires.

Abilities

Cursed energy and combat skill

An extraordinary reservoir of cursed energy complements Sukuna’s physical prowess, reflexes, and ability to analyze an opponent’s technique.

Dismantle

A cutting attack from Sukuna’s Shrine technique that can slash targets without relying on a conventional blade.

Cleave

A Shrine cutting attack that adjusts its force to a target’s toughness and cursed energy; Sukuna commonly applies it at close range.

Malevolent Shrine

Sukuna’s Domain Expansion brings his slashing technique into a broad area without enclosing it in the usual sealed barrier.

Reverse cursed technique

Sukuna can use reverse cursed energy to regenerate serious bodily injuries, illustrating refined control beyond raw offensive output.

Relationships

Yuji Itadori

Initial vessel and adversary

Yuji contains Sukuna inside his body and resists his attempts to seize control. Sukuna considers this resistance an indignity and repeatedly antagonizes him.

Megumi Fushiguro

Sorcerer who draws his interest

Megumi’s abilities attract Sukuna’s attention early in the story; Sukuna studies his potential rather than dismissing him outright.

Satoru Gojo

Opposing jujutsu sorcerer

Gojo is a formidable modern sorcerer whose position defending Yuji places him in opposition to the King of Curses.

Interesting facts

The official anime character listing credits Junichi Suwabe as Sukuna’s Japanese voice actor.

It identifies the performer behind the character’s distinctive vocal presence in the anime adaptation.

The official character-guide material summarized by ORICON identifies eating as something Sukuna enjoys.

It is a small, specific personal preference that contrasts with the largely combative way readers usually encounter him.

Frequently asked questions

Who is Ryomen Sukuna in Jujutsu Kaisen?

He is an ancient sorcerer called the King of Curses whose power survives in cursed fingers and reawakens in Yuji Itadori.

Is Sukuna a cursed spirit?

No. His title and the cursed objects containing his power can be misleading, but Sukuna originated as a powerful sorcerer rather than a typical cursed spirit.

Why does Sukuna appear in Yuji Itadori?

Yuji swallows one of Sukuna’s preserved fingers, becoming a vessel able to contain the ancient sorcerer.

What is Sukuna’s Domain Expansion?

Malevolent Shrine is a domain that deploys slashing attacks over an area without the conventional closed barrier.

What are Cleave and Dismantle?

They are cutting applications of Sukuna’s Shrine technique, with Cleave adapting to the target’s durability and cursed energy.

Why is Sukuna called the King of Curses?

The epithet reflects his extreme power and feared reputation across centuries of jujutsu history.

Does Sukuna respect anyone?

He rarely offers warmth or allegiance, but exceptional techniques and opponents can earn his attention. Attention does not necessarily mean benevolence.

Major story spoilers below.

Destruction in Shibuya

During the Shibuya Incident, Sukuna gains control of Yuji after a sudden intake of more fingers. He kills Jogo and defeats Mahoraga, a formidable shikigami involved in Megumi’s desperate summoning ritual. His actions devastate Shibuya and burden Yuji with the consequences after control returns.

The binding vow and the new vessel

Sukuna eventually invokes a previously established one-minute binding vow with Yuji. Exploiting its terms, he turns part of Yuji’s body into a cursed object and forces Megumi to swallow it, transferring his incarnation into Megumi’s body. That move changes the confrontation from containing Sukuna to rescuing someone he has taken over.

Overpowering Megumi’s resistance

Sukuna works to crush Megumi’s resistance to possession. He undergoes a ritual intended to bury his new host’s sense of self, then confronts Yorozu, who has incarnated in Megumi’s sister Tsumiki. Using that body against Megumi turns his family bond into a means of suppressing him.

Clash of the strongest

Sukuna fights Satoru Gojo in a contest of repeated Domain Expansions, intricate technique adjustments, and Mahoraga’s adaptation to Gojo’s defenses. Sukuna develops a slash that targets the space containing its victim and defeats Gojo. Hajime Kashimo then challenges him, after which Sukuna completes his incarnation in his original four-armed body.

A succession of challengers

The remaining sorcerers mount a prolonged, shifting assault. Higuruma’s attempt to confiscate Sukuna’s cursed technique fails, Yuta Okkotsu opens his domain, and Yuji repeatedly strikes the boundary between Sukuna’s soul and Megumi’s. Sukuna recovers some power through Black Flash and later unleashes his devastating flame technique inside Malevolent Shrine, but the challengers keep forcing him to respond.

The twin’s soul and Yuji’s grandfather

Sukuna reveals that he consumed his twin in the womb. His account initially invites the conclusion that Yuji’s father, Jin Itadori, carries that twin’s reincarnated soul, but Gege Akutami’s extra material in manga Volume 29 clarifies that the matching soul belongs instead to Yuji’s grandfather, Wasuke Itadori. This family connection does not soften Sukuna’s hostility to Yuji.

Defeat at the soul’s boundary

In the final confrontation, Yuji attacks the boundary between Sukuna’s soul and Megumi’s, while Nobara Kugisaki uses her technique on Sukuna’s remaining finger. Megumi resists from within; Sukuna is torn out and disintegrates. Yuji offers to take him back as a vessel rather than leave him to die, but Sukuna rejects the offer.

The final chapter’s different road

The final chapter depicts Sukuna meeting Mahito in a passage between lives. He acknowledges that he might have lived differently and considers another path if given a next time, leaving with a younger Uraume in the scene. The manga closes on his last finger being used as a protective charm, not on a confirmed resurrection.

Additional story facts

Mahoraga’s adaptation gives Sukuna a model for extending his cutting technique past Gojo’s Infinity.

The decisive attack grows out of careful observation and the interaction of two techniques, rather than superior force alone.

The extra pages of Volume 29 clarify that Wasuke Itadori—not Jin Itadori—shares the soul of Sukuna’s consumed twin.

The author’s later clarification changes how the revelation in chapter 257 should be read and corrects a common account of Yuji’s family connection.

Spoiler questions

Does Sukuna take over Megumi Fushiguro?

Yes. During the Culling Game, he uses his binding vow with Yuji to transfer his incarnation into Megumi and later works to suppress Megumi’s resistance.

Who wins between Gojo and Sukuna?

Sukuna defeats Satoru Gojo after an extended fight involving repeated domains and Mahoraga’s adaptation.

How is Yuji related to Sukuna?

Sukuna consumed his twin before birth. Volume 29’s additional material clarifies that the twin’s soul is linked to Yuji’s grandfather, Wasuke Itadori, rather than to Yuji’s father, Jin.

What happens to Sukuna at the end of Jujutsu Kaisen?

Yuji and his allies separate Sukuna from Megumi, ending Sukuna’s incarnation. The last chapter then depicts Sukuna considering whether he might choose a different way to live in another life.

Does Sukuna return from the final finger?

No return is depicted in the completed original manga. Yuji regards the surviving finger as no longer capable of reviving Sukuna, and it is left as a charm that wards off curses.
