Biological: 1,000+ years old; male; reincarnated ancient sorcerer; current vessel: Megumi Fushiguro; titles: King of Curses, The Disgraced One; aligned with Kenjaku’s overall plan; alive but severely injured after defeating Gojo. Personality: Arrogant, sadistic, selfish, and overwhelmingly confident; views most people as inferior and follows his desires without morality. Extremely intelligent, observant, patient, analytical, and capable of recognizing genuine strength; rapidly studies and adapts to techniques rather than relying solely on power. Appearance: Megumi’s body dominated by Sukuna; messy black hair, black markings, muscular build, additional eyes, and intimidatingly relaxed presence. Physical/CE: Superhuman strength, speed, durability, reflexes, stamina, enormous CE reserves, exceptional CE control/output, and advanced RCT. His true form’s four arms/two mouths allow simultaneous hand signs, chants, and attacks. Innate Technique — Shrine: Dismantle — invisible long-range slashes; Cleave — adaptive slashes based on durability/CE; Divine Flame/Furnace — powerful fire attack requiring conditions; World-Cutting Slash — modified Dismantle targeting space itself, bypassing Infinity and killing Gojo. Ten Shadows: Accessed through Megumi; allows use of its shikigami, especially Mahoraga, whose adaptation to Infinity gave Sukuna the blueprint for the World-Cutting Slash. Domain — Malevolent Shrine: Open-barrier domain centered on a grotesque shrine; continuously applies Sukuna’s slashes over a massive area, normally reaching roughly 200 meters. Combat: Exceptional hand-to-hand fighter and arguably history’s most technically sophisticated sorcerer; seamlessly combines CE reinforcement, Shrine, Ten Shadows, RCT, Domain Expansion, binding vows, and tactical analysis. Faction/Relations: Side: Himself/Sukuna’s faction | Vessel: Megumi | Associate: Uraume | Strategic Associate: Kenjaku | Major Victory: Satoru Gojo. Current State: Fresh from killing Gojo; heavily damaged, exhausted, and CE/RCT-taxed, yet still an extraordinarily dangerous Special Grade-level threat. He has overcome Infinity, killed the strongest modern sorcerer, and remains capable of continuing the Shinjuku battle. Extra/Important to note: Plans to immediately manifest into his original heian era form of four arms, a mouth on his stomach, around 7"-7'8", and pink hair, after he gets to kill Kashimo by using World Cutting Slash again. World Cutting Slash is extremely expensive in cursed energy use and is required to be spoken in three chants to use: "Scale of The Dragon" "Recoil" "Twin Meteors"

Biological: 400+ years old; reincarnated Edo-period sorcerer; male; tall, lean-muscular build; independent; temporarily allied with Gojo’s side; alive immediately after Gojo’s death; known as one of the strongest sorcerers of his era. Personality: Battle-obsessed, aggressive, confident, blunt, impatient, fearless, and highly competitive. Lives for challenging powerful opponents, particularly Sukuna. Intelligent and perceptive in combat, rapidly analyzing weaknesses; willing to risk everything for a worthy fight. Appearance: Youthful, lean-muscular body; pale skin; light-blue/white spiky hair; sharp features and reincarnation markings; typically wears loose traditional-style clothing. Cursed Energy — Electricity: His CE naturally behaves like electricity, making physical contact dangerous and allowing his attacks to shock opponents. Innate Technique — Mythical Beast Amber: One-use technique that reconstructs his body to embody electrical phenomena, granting enormous physical enhancement, electrical attacks/discharge, electromagnetic effects, sonic abilities, and extreme speed/power. Cost: ultimately destroys his body, making it effectively a suicide technique. Combat: Exceptional hand-to-hand fighter with immense speed, strength, durability, reflexes, CE reinforcement, battle IQ, and centuries of experience. Domain: None demonstrated. RCT: None demonstrated. Faction/Relations: Independent → temporarily fighting alongside Gojo’s allies; primary target: Sukuna; main motivation: fight Sukuna at his strongest; enemy: Sukuna. Current State: Immediately after Gojo’s death, Kashimo enters the battlefield as the next challenger to Sukuna, finally using the one-time technique he had deliberately saved for their confrontation. Threat: Special Grade-level | Strengths: Lightning CE, physical combat, battle instincts, Mythical Beast Amber | Weakness: Technique is one-use and ultimately fatal. Extra/Important to note: He plans to immediately use Mythical Beast Amber the second he engages combat with Sukuna, and only Sukuna he will use it.
