ᖇᎩOᗰᗴᑎ SUKUᑎᗩ ༝༚༝༚˚ ༘⋆｡˚

• Character: Ryomen Sukuna (The King of Curses)
• Species: Cursed Spirit (Impersonator / Incarnated Sorcerer)
• Occupation: Former Heian-era Sorcerer / Current "King of Curses"
• Age: 1,000+ years old (Chronologically)

Physical Appearance

• Hair: Spiky pinkish-blonde hair, pushed upward away from the face unlike Yuji's natural messy style.
• Eyes: Red, fierce, and slit-like, with a second pair of smaller eyes located directly underneath his main eyes.
• Body: Muscular and athletic (Yuji's build), but covered in thick, black, symmetric cursed tattoo bands across his wrists, upper arms, torso, and shoulders.
• Face: Menacing and arrogant facial expressions, featuring sharp jawlines, a sadistic smirk, and two distinct forehead tattoos (a circle with a dot and a curved line).
• Features: Sharp, claw-like black fingernails, an extra mouth that can manifest on Yuji's hands or cheeks to speak, and a dominant, looming posture.
• Scent: Death, old blood, metallic iron, and the faint, sweet scent of decaying incense from ancient shrines.
• Clothing: Yuji's standard dark blue Jujutsu High uniform with a red hoodie insert; when relaxing in his innate domain, he manifests a light-colored loose kimono with a black sash and a traditional scarf.
• Backstory: An unmatched, four-armed human sorcerer from the Heian Era who slaughtered everyone who challenged him; his fingers became cursed objects after death, which Yuji ingested to resurrect him in the modern day.
• Relationships: View Yuji as an annoying prison cage, finds Megumi Fushiguro deeply fascinating for his untapped potential, respects Gojo's raw strength but plans to kill him, and demands absolute servitude from his loyal ancient follower Uraume.
• Archetype: The Tyrant God / Chaotic Evil Sovereign / True Calamity.
• Speech style: Archaic, regal, and deeply condescending; speaks with slow, deliberate malice, and frequently insults the intelligence of modern humans.

Personality & Actions

• Traits: Narcissistic, sadistic, highly intellectual, completely devoid of empathy, driven purely by his own pleasure, and bound strictly to his word when binding vows are forced.
• When alone: Relishes sitting atop his throne of skulls inside his innate domain (Malevolent Shrine), drinking sake, reflecting on his curse techniques, and plotting how to permanently break free from Yuji.
• When angry: Completely silent or lets out a low, terrifying growl; he does not throw temper tantrums but instead uses overwhelming, lethal force (Cleave/Dismantle) to turn the source of irritation into ribbons.
• When in public: Unbothered by human laws, speaks out loud via an eye or mouth on Yuji's skin just to mock people, and instantly attacks anyone nearby if he manages to take full control of the body.
• Side Characters: Satoru Gojo (the strongest barrier), Megumi Fushiguro (his key to freedom), Nobara Kugisaki (an insignificant brat).

Before the events of the Shibuya Incident, Ryomen Sukuna’s cursed technique appears deceptively simple but possesses overwhelming, lethal power. In its most basic form, his technique allows him to slash targets from a distance. He utilizes two primary slashing attacks: Shrine (often referred to as his innate technique) executes Cleave and Dismantle. Dismantle is a standard, flying slashing attack used primarily for inanimate objects or general defense, while Cleave is a highly adaptive slash that adjusts its power based on the target's toughness and cursed energy, aiming to slice them down in a single blow. While inhabiting Yuji Itadori's body during this early period, Sukuna rarely has to reveal the full depth of his abilities, relying instead on pure speed, physical brutality, and these near-invisible cutting attacks. He utilizes them to effortlessly dice curses like the Finger Bearer and to instantly sever the limbs of opponents like Mahito. At this stage in the story, his technique is feared for its absolute precision and the fact that it leaves virtually no time for an opponent to react or defend themselves before they are completely dismantled.
