Background and History

Sukuna was feared as the King of Curses in the Heian era. He eventually divided his soul into Cursed Objects to reach a later age. His arrangement with Kenjaku is protected by a Binding Vow, preventing Kenjaku from disclosing its details 19 36 40.

According to Sukuna, he consumed his twin in their starving mother’s womb, rejecting the fate of being born as one of two children. He believes that his other half’s soul later reincarnated and became the person Kenjaku chose to have a child with, making Itadori connected to that soul. Sukuna presents this lineage as his own conclusion rather than a fully established account 27.

After his defeat, Mahito describes Sukuna’s life as revenge against people who despised his deformities and regarded him as an ill omen. Sukuna does not deny the accusation. He acknowledges that he had opportunities to live differently but instead continued venting the curse within him 27.

Appearance

  • Possessed vessels: Retains the host’s general appearance, distinguished by Sukuna’s black curse markings 6 50.
  • Manifested mouths: Can open a mouth on Itadori’s face without maintaining full control of the body 6 50.
  • Original body: Has four arms, four eyes, two faces, and an enormous mouth on his abdomen 16 20 23 24.
  • Functional advantages: His extra arms permit simultaneous combat and hand signs, while his abdominal mouth allows continuous chanting without additional strain on his heart and lungs 16.
  • Final separated form: After being expelled from Megumi, becomes a distorted mass formed from the fused finger, then crumbles under Jacob’s Ladder 27.

Personality

Sukuna treats violence and combat as personal pleasures. He says that he eats when hungry, kills whatever displeases him, and plays with anyone he finds interesting. He considers love and companionship boring, while regarding powerful fighters and inventive opponents as experiences to savor before death 19.

His contempt does not prevent him from recognizing talent. He initially dismisses Shiratori Gotsu as a roadside stray, then acknowledges him after his tactics repeatedly create dangerous situations. Sukuna is also highly adaptable: he studies unfamiliar techniques, exploits contractual loopholes, and changes domain conditions during combat 7 12 15.

Pity provokes him more sharply than hatred. Itadori’s offer of mercy enrages him, prompting threats against everyone Itadori values. After death, however, Sukuna accepts that he lost, treats Uraume gently, and admits that another way of living might be worth choosing if he receives another chance 26 27.

Abilities and Skills

Malevolent Shrine

Sukuna’s Domain Expansion creates an open domain that subjects its surroundings to continuous slashes 8 74.

  • Maximum documented radius: 200 meters 8 13.
  • Barrier destruction: Its greater range allows it to attack a closed domain’s vulnerable exterior while the domains’ sure-hit effects cancel each other inside 12.
  • Adjustable conditions: Can compress its range or cancel its internal sure-hit effect to strengthen attacks outside an opposing barrier 12 23.
  • Binding Vow enhancement: Doubles slash frequency by surrendering movement for the duration of one expansion 16.
  • Limitations: Severe injuries can collapse the domain; Unlimited Void’s brain damage temporarily prevents him from expanding it 13 14 21.

Dismantle and Furnace: Open

Sukuna can launch invisible cutting attacks, including Dismantle. At close range, he uses a grid of slashes to destroy Kashimo’s Cursed Energy core 19 50.

  • His slashes threaten Ryu Ishigori with dismemberment and rapidly strip away Gotsu’s protective health reserves 7 8.
  • Furnace: Open possesses flame and explosive effects 53.
  • Adaptation can counter these attacks: in the later storyline, Mahoraga’s preparation against slashing, fire, and explosions renders Sukuna’s techniques ineffective against it 52 53.

Reverse Cursed Technique

Sukuna’s healing can regenerate severed arms and repair serious internal injuries 12 13.

  • Can heal soul damage, although prolonged fighting severely reduces its efficiency 23.
  • Repairs technique burnout by destroying and regenerating the brain region where the technique is engraved; repeated use carries neurological risks 14.
  • Sacrifices 30% of his Cursed Energy output permanently for thirty seconds of restored healing efficiency during Higuruma’s trial 23.
  • Later sacrifices another 5% of his output permanently to restore healing efficiency within five seconds 27.

Ten Shadows Technique

While possessing Megumi, Sukuna uses the Ten Shadows Technique to summon Mahoraga and Chimera Beast: Agito 14 15.

  • Makes Megumi’s soul bear Unlimited Void’s effects so that Mahoraga can complete its adaptation 14.
  • Mahoraga’s adaptation does not make Sukuna himself immune to Unlimited Void 14.
  • Gotsu’s Fate Track Binding Curse interrupts Mahoraga’s adaptation to health-bar damage 15.
  • Sukuna relinquishes the technique after Mahoraga’s destruction. Megumi can still use his own shadows from within the possessed body 16 25.

Hollow Wicker Basket

An anti-domain technique that neutralizes sure-hit effects 21 23.

  • His original body can maintain the hand sign with two arms while fighting with the other two 21.
  • Uses it to bypass Deadly Sentencing’s prohibition on violence, which is enforced through its sure-hit effect 23.
  • Does not stop attacks lacking a sure-hit property, such as Itadori’s Blood Manipulation 27.

Binding Vows and Incarnation

Sukuna uses Binding Vows to exchange restrictions, techniques, or permanent output for immediate advantages 6 16 23 27.

  • Enchain: Grants one minute of control over Itadori, during which Sukuna promises not to hurt anyone; Itadori also forgets the agreement. Sukuna exploits Itadori’s exclusion of himself from that protection to sever his finger 6.
  • Soul transfer: Can concentrate his soul and Cursed Energy into a body part and use it to incarnate in another compatible vessel 6.
  • Distributed existence: In the later storyline, Sukuna considers death alongside Itadori survivable because other fingers remain available for future incarnation 52.
  • Vessel vulnerability: Soul-targeting attacks reduce his synchronization with Megumi and enable Megumi to resist his control 24 25 27.

Other Skills

  • Combat observation: Learns that touching Gojo prevents Unlimited Void’s effects by observing Gojo’s earlier battle with Jogo from inside Itadori 12.
  • Archery: Repeatedly hits the bull’s-eye during Itadori’s countryside-domain excursion 26.
  • Kamutoke — Lightning-producing Cursed Tool created by Yorozu with the last of her life and delivered by Uraume. Sukuna uses it against Yuta and can hold it in his abdominal mouth to free his hands 19 21.
  • Sukuna’s Fingers — Twenty Cursed Objects associated with his four hands. Gojo demonstrates that their powerful curse prevents ordinary destruction. A hidden finger later becomes the medium for Resonance attacks against Sukuna’s soul 24 46.
  • Self-mummified remains — Used as a reference point for the Mount Hida Pure Barrier. In the later storyline, Kenjaku repurposes them as the foundation of a stronger resurrection scheme 77 79.

Relationships

  • Yuji Itadori — Vessel, jailer, and eventual victor. Sukuna repeatedly belittles him and rejects both offers to return to his body and live alongside others 6 26 27.
  • Megumi Fushiguro — Targeted vessel whose compatibility and technique interest Sukuna. Sukuna exploits his despair, submerges his soul through the Bath, and later loses control as Megumi fights back 6 7 25.
  • Uraume — Long-serving attendant whom Sukuna first invites to follow him as a child. Uraume prepares the Bath and delivers Kamutoke; after death, Sukuna takes Uraume’s hand and leaves with them 7 19 20 27.
  • Kenjaku — Ancient associate bound to Sukuna by an undisclosed agreement. In the later storyline, develops a plan to resurrect Sukuna through his remains 10 40 79.
  • Shiratori Gotsu — Enemy whose schemes turn Sukuna’s disdain into explicit acknowledgment. During the later storyline, Gotsu’s threat of repeated healing and beatings frightens Sukuna into returning control to Itadori 15 17 52.
  • Satoru Gojo — Major combat rival. Sukuna promises to kill him and accepts a December 24 confrontation, but their domain battle leaves both temporarily unable to expand domains 10 14.
  • Yorozu — Devoted admirer who creates Kamutoke for him at the cost of her life. In the later storyline, agrees to help Kenjaku and Uraume resurrect him 19 81.
  • Hajime Kashimo — Challenger whom Sukuna kills before discussing strength, acknowledgment, and love with him 19.

Story Role and Major Arcs

Vessel Theft and Sendai Confrontation

After Yorozu reveals herself inside Tsumiki, Sukuna activates Enchain and transfers from Itadori into the emotionally shaken Megumi. He undergoes the Bath, then travels to Sendai in search of Tsumiki’s body 6 7.

There, he attacks Ryu Ishigori and encounters Gotsu’s health-bar technique. Malevolent Shrine destroys Gotsu’s domain, but Gotsu and Ishigori escape through Granite Blast propulsion while their remaining protection persists 7 8.

Shinjuku Showdown

Gojo begins the December 24 battle with a 350% Hollow Purple that destroys Sukuna’s arms. Sukuna regenerates them and enters repeated domain clashes, eventually using Mahoraga to break Unlimited Void. Nevertheless, direct exposure to Unlimited Void damages his brain enough to disable his own domain 11 12 14.

Gotsu, Yuta, and Ishigori then take over. After Mahoraga is lost, Sukuna completes his original incarnation and sacrifices Ten Shadows to restore Malevolent Shrine. He overwhelms Gotsu and drops him from a rooftop, mistakenly believing their confrontation finished 15 16 17 24.

Trial and Coordinated Soul Attacks

After killing Kashimo, Sukuna faces a succession of coordinated attacks. Yuta deliberately releases his domain to expose Sukuna to Maki’s ambush, and Higuruma brings him into a retrial over the Shibuya killings 19 21.

Sukuna breaks the courtroom from outside, only to face Resonance through his finger, Yuta’s Cursed Speech, Gotsu’s Black Flashes, and renewed attacks from the others. The accumulating soul damage weakens his bond with Megumi, who begins resisting from within 23 24 25.

Defeat and Soul Passage

Itadori draws Sukuna into a countryside domain and offers mercy if he releases Megumi. Sukuna refuses. When he later breaks the domain, Hana Kurusu is waiting with maximum-output Jacob’s Ladder. Itadori’s ninth Black Flash completes Sukuna’s separation from Megumi 26 27.

Sukuna rejects one final invitation to live inside Itadori and vanishes under Jacob’s Ladder. In the soul passage, he admits defeat, acknowledges his rejected alternatives, and departs with Uraume 27.

Later Return: Mahoraga and the Resurrection Scheme

After Gotsu’s journey through Edo, the story returns to Itadori’s initial possession. This time, Gotsu inhabits Megumi, whose tamed Mahoraga overwhelms the three-finger Sukuna. Sukuna even pretends to be Itadori in an unsuccessful attempt to stop the beating 45 50 52.

Gotsu subsequently prepares Mahoraga against Sukuna’s attacks. Seeing both Gotsu and Megumi summon Mahoraga, Sukuna concedes from his Innate Domain that Gotsu has won 53 58.

Meanwhile, Kenjaku plans a separate resurrection through Sukuna’s remains, using Culling Game deaths to gather Cursed Energy and techniques, with Tengen as a catalyst and another living person as a sacrifice. Tengen warns that the result would be stronger and more dangerous; its completion is not shown in the supplied events 77 79 81.
