Power Progression

Stage / Realm / Level Chapter Notes
Yuji Itadori’s vessel 13–14 Manifested through Yuji, but was constrained by the Enchain Binding Vow: during his one-minute control period, he could not kill or harm anyone. He concentrated his soul and power into Yuji’s severed little finger to make a new cursed object. 13 14
Jie Jian incarnation 15 Forced Jie Jian to swallow the finger and resurrected through his body. He could access only memories beginning with Jie Jian’s arrival in the Culling Game barrier. 15
Cursed Womb vessel 50 Revived in a Cursed Womb body, then destroyed Mahoraga with a single Hachi slash. 50
Ancient true form 59 Restored his original body to instantly regenerate catastrophic damage from Jie Jian’s ambush. 59
Yorozu armor fusion 67 Yorozu merged into black metal armor around Sukuna, greatly increasing his physical strength, speed, defense, and cursed-energy reserves. 67
Megumi Fushiguro’s vessel 144 Completed his possession of Megumi, gaining access to the Ten Shadows Technique and its shikigami. 144
Original four-armed body 167 Restored his original four-armed, four-eyed body after his domain was shattered, dramatically increasing his cursed energy. 167
Fully utilized original body 197 His four arms and abdominal mouth allowed him to fight, form hand seals, aim techniques, and chant simultaneously. 197

Background / History

Before his birth, Sukuna was a twin. He devoured his own twin while still a fetus, consolidating and strengthening his power; the twin’s soul later reincarnated as Wasuke Itadori, Yuji Itadori’s grandfather. Sukuna himself was unaware of this connection until Jie Jian revealed it. 13

While residing within Yuji, Sukuna showed interest only in Satoru Gojo as a worthy opponent and dismissed Hajime Kashimo as beneath his notice. After Kashimo exposed Sukuna’s intent to change vessels, Sukuna exploited the Enchain vow’s one-minute window, converted his power into Yuji’s little finger, and forced Jie Jian to consume it. 13 14 15

Sukuna briefly incarnated in Jie Jian’s body, but intended from the outset to claim Megumi Fushiguro for the Ten Shadows Technique. Kenjaku aided this plan by using Yorozu—incarnated in Tsumiki Fushiguro’s body—to emotionally devastate Megumi and make possession easier. 15 16

He eventually possessed Megumi and prepared the Bath ritual to suppress Megumi’s soul and perfect his control over the body. When Hana Kurusu attempted to separate him from Megumi with Jacob’s Ladder, Sukuna deceived her by pretending Megumi had returned, then attacked her. 144 146

Appearance

Sukuna’s appearance changes with his vessel and transformations. His original body is defined by two faces, four arms, four eyes, and an additional mouth on his abdomen. 13 167 197

  • In Yuji and Megumi’s bodies, Sukuna manifests distinctive facial markings and an additional eye. 144
  • His true form can regenerate severe bodily destruction as it replaces an incarnated vessel’s form. 59 167
  • Yorozu’s fusion temporarily covered him in black metal armor, including his teeth and hands. 67
  • His original body’s extra arms and abdominal mouth allow simultaneous combat, hand signs, targeting, and chanting. 197

Personality

Sukuna is contemptuous of weakness and selective about opponents. He ignored Kashimo’s demand for a duel, regarding Gojo as the only contemporary sorcerer worth his attention. 13

He is highly pragmatic and treats deception, sacrifice, and Binding Vows as ordinary tools of combat. He manipulated Yorozu’s obsession by promising her love, future, heart, and body solely to obtain her power; he later used a false request to see Jie Jian’s domain as a trap. 63 169 170

His pride is intense. Sukuna refused to evade a reflected slash because doing so would make him appear inferior to Jie Jian, yet he can rapidly abandon ineffective tactics when necessary, switching from domain attacks to Domain Amplification and close combat. 151 161

Abilities & Skills

Shrine and Slashing Techniques

Sukuna’s primary cursed technique is a collection of slashing attacks capable of ranged destruction, close-contact execution, and large-scale barrages.

  • Dismantle — invisible slashes used against opponents at range; Miwa later learned to block them with her sword. 226
  • Cleave — a slashing attack Sukuna attempted against Jie Jian, only for it to be reflected back and injure his arm. 145
  • Hachi — a powerful slash that normally requires physical contact, but can be deployed without contact within Malevolent Shrine. 41 60
  • Hachi: Spiderweb — shatters the ground and turns debris into cover or an escape route. 61
  • Grid Slash — an overlapping mass of slashes forming a grid-like pattern. 227
  • Spatial Slash — a more dangerous slash developed through Mahoraga’s adaptation; it can bypass conventional defenses such as Gojo’s Limitless. 195 197

Domain Expansion: Malevolent Shrine

Sukuna’s Domain Expansion is an Open Domain without a closed barrier. Its slashes can attack the exterior of conventional domains and destroy them from outside. 156

  • Grants his slashes a guaranteed-hit effect within its range. 60
  • Lets him use Hachi without physically touching the target. 60
  • Can be used strategically against terrain rather than opponents, as when Sukuna sliced apart Jie Jian’s thunderstorm clouds. 64
  • Its slashes were ineffective against Jie Jian’s Elementalization and Reflection-based defenses. 156 171
  • Can be interrupted or collapsed when Sukuna’s cursed energy is disrupted during activation. 60 71

Furnace: Open

Sukuna’s hidden fire technique produces destructive explosions and a Flame Arrow.

  • Used explosive cursed energy infused into Malevolent Shrine’s slashed storm clouds to erase Jie Jian’s source of lightning replenishment. 64
  • Could not completely destroy Jie Jian’s massive lightning form in one strike. 63
  • His Flame Arrow collided with Jie Jian’s Lightning Cannon, devastating Shinjuku and shattering Malevolent Shrine. 166 167

Reverse Cursed Technique

Sukuna possesses extremely efficient self-healing.

  • Instantly repaired devastating injuries such as the damage from Jie Jian’s kick. 41
  • Regenerated lost limbs and rebuilt his body after attacks destroyed large portions of it. 59 166 167
  • Repeated healing gradually reduced its effectiveness during his battle against Miwa. 229 231

Incarnation and Vessel Control

Sukuna can turn portions of his soul and power into cursed objects, then incarnate through a compatible host.

  • Taking flesh from a vessel ordinarily grants access to its memories and cursed technique. 15
  • He selected Megumi specifically to inherit the Ten Shadows Technique. 15
  • The Bath ritual strengthens an incarnated sorcerer’s control by suppressing the original host’s soul. 16 51
  • Megumi’s soul continued to interfere with Sukuna’s control before the Bath was completed. 49

Ten Shadows Technique

After possessing Megumi, Sukuna used the Ten Shadows with far greater cursed-energy output than Megumi had shown.

  • Nue — summoned as an enormous airborne shikigami capable of powerful lightning attacks. 144
  • Mahoraga — summoned to adapt to opponents’ techniques and phenomena; Sukuna used its adaptation to develop the Spatial Slash. 195 231
  • Agito — a chimera shikigami with inherited techniques and strong Reverse Cursed Technique through Round Deer. 229

Domain Amplification

Sukuna coats himself in Domain Amplification to neutralize cursed techniques on contact.

  • Allowed him to bypass Jie Jian’s protective barrier and engage him physically. 161
  • Could not stop Jie Jian from elementalizing body parts before contact, causing Sukuna’s strikes to pass through lightning. 166

Equipment / Weapons / Items

  • Kamutoke — a lightning-firing cursed tool originally used by Sukuna in the Heian era; Uraume later provided him a Yorozu-made replica with the original’s abilities. 201
  • Yorozu’s metal armor — Yorozu merged her body and cursed energy with Sukuna, creating armor that restored much of his depleted power and enhanced his physical capabilities. 67

Relationships

  • Yuji Itadori — former vessel and enemy; Sukuna used Yuji’s body before escaping through Yuji’s severed finger. 13 14
  • Megumi Fushiguro — chosen vessel; Sukuna coveted Megumi’s Ten Shadows Technique and ultimately possessed his body. 15 144
  • Uraume — devoted servant who collects Sukuna’s fingers, prepares the Bath, supplies Kamutoke, and repeatedly intervenes for Sukuna’s safety. 16 201
  • Kenjaku — cautious ally who assisted Sukuna’s vessel plans and used Yorozu to lure Megumi. 16
  • Yorozu — obsessive admirer whose love Sukuna exploited for combat power; he regarded her as a useful tool rather than a partner. 16 63 68
  • Satoru Gojo — opponent Sukuna considered worthy of his attention; their battle centered on Malevolent Shrine, Infinite Void, Mahoraga’s adaptation, and the Spatial Slash. 13 195 197
  • Jie Jian — recurring rival whose intelligence, Reflection, Vector Manipulation, and Undying Thunder repeatedly forced Sukuna to change tactics. 145 161 166
  • Kasumi Miwa — later opponent empowered by her partnership with Jie Jian; Sukuna initially dismissed her as weak before she destroyed his domain, Agito, and Mahoraga. 224 226 230 232

Story Role / Major Arcs

Initial Resurrection and Vessel Hunt

Sukuna escaped Yuji’s control by converting himself into a finger and forcibly incarnating through Jie Jian. After defeating Kashimo, he reunited with Uraume and pursued Megumi as a superior vessel. 14 15 16

Tokyo Decisive Battle

Sukuna survived Jie Jian’s prepared Thunder Cannon by restoring his true form, deployed Malevolent Shrine, destroyed Jie Jian’s thundercloud supply with Furnace: Open, and fused with Yorozu’s metal body. Higuruma temporarily confiscated his slashing technique, but Kenjaku’s intervention restored Sukuna’s advantage. 59 64 67 70

Possession of Megumi

Sukuna seized Megumi’s body and used the Ten Shadows Technique against Yuji, Hana, Maki, and Jie Jian. He withdrew with Uraume to complete the Bath and secure control over Megumi. 144 146

Shinjuku Battle

Sukuna fought Gojo and Jie Jian while revealing the tactical advantage of his Open Domain, Domain Amplification, original body, and multiple techniques. Although he destroyed Jie Jian’s domain from the outside, Jie Jian bypassed Cursed Technique Burnout through Elementalization and Reverse Cursed Technique. 156 161 167 170

Miwa’s Reborn Timeline

After Kasumi Miwa challenged Sukuna at the Zenin estate, he underestimated her and was repeatedly wounded by her Black Flash-infused sword techniques. Miwa destroyed Malevolent Shrine, Agito, and Mahoraga before Sukuna attempted to flee; she defeated him but hesitated to deliver a final blow because Megumi’s body remained his vessel. 226 230 232
