================================================================================ JUJUTSU SORCERY — COMPREHENSIVE INFO DUMP

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ I. FOUNDATIONAL CONCEPTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

CURSED ENERGY

• The fundamental resource of all jujutsu combat.
• Generated by negative human emotions: fear, grief, hatred, regret, shame.
• Flows naturally out of the body in an uncontrolled person (like heat from skin).
• Sorcerers learn to control this flow — stopping leakage, redirecting output.
• Cannot be sensed by ordinary humans. Cursed spirits and sorcerers can perceive it.
• Acts as both fuel and weapon. Raw cursed energy can be hardened around the body to reinforce strikes, defend against attacks, or propelled outward as blasts.
• Quality matters as much as quantity. Refined, dense cursed energy is more efficient and more dangerous than a larger but diffuse amount.

CURSED SPIRITS

• Born from accumulated cursed energy that has no host — pooled from the fears of ordinary humans over time, crystallising into entities.
• They are not alive in a conventional sense. They are manifestations of concept and emotion. A spirit born from fear of the ocean IS the ocean's malice.
• Grade determines threat level (see GRADING SYSTEM below).
• Special Grade Cursed Spirits (Mahito, Jogo, Hanami, Dagon, etc.) possess their own Innate Techniques, functioning similarly to sorcerers.
• Can only be harmed by cursed energy. Conventional weapons pass through or do negligible damage. This is why ordinary humans are entirely helpless.

REVERSE CURSED TECHNIQUE (RCT)

• Standard cursed energy is negative in nature.
• Multiplying two negative values produces a positive output.
• RCT is achieved by multiplying cursed energy by itself to generate "positive energy" — the only known energy capable of healing living tissue.
• Extremely rare. Most sorcerers cannot perform RCT.
• Masters of RCT can heal catastrophic, ordinarily fatal injuries in seconds.
• Can also be weaponised offensively (see: Hollow Purple).

BINDING VOWS

• Contracts that govern the use of cursed energy.
• Accepted limitations on one's own technique generate additional power as compensation. The greater the restriction, the greater the gain.
• Example: Revealing your technique to an opponent before using it dramatically increases its output — because you have handicapped yourself through disclosure.
• Vows can exist between two parties or as a self-imposed rule.
• Breaking a binding vow has consequences. The power gained is forfeit, and further penalties may apply depending on the terms.
• Malevolent Shrine operates on a binding vow — the absence of a barrier is compensated for with a guaranteed-hit sure-hit condition within range.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ II. CURSED TECHNIQUES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

INNATE TECHNIQUE

• A technique born into a sorcerer — encoded in their cursed energy from birth.
• Cannot be learned or taught. It is a biological and spiritual inheritance.
• Most sorcerers have one Innate Technique. It is theirs alone.
• The brain governs the technique; damage to the brain disrupts its use.
• Techniques can be developed, refined, and extended — but the core is fixed.

EXTENSIONS

• Sub-applications built from the foundation of an Innate Technique.
• Require mastery of the base technique before they can be developed.
• Cleave is an extension of Shrine (adapts to target durability).
• Extensions add versatility; they do not replace the core.

MAXIMUM TECHNIQUE

• The absolute ceiling of an Innate Technique — full output, nothing held back.
• Typically a technique pushed to a scale, speed, or intensity beyond normal use.
• Draining to use. Not sustainable in extended combat.

DOMAIN EXPANSION

• The pinnacle of jujutsu.
• A sorcerer compresses their Innate Technique and their inner world — their soul, essentially — and manifests it as a physical space.
• Inside a Domain, the user's technique is granted "sure-hit" status. Every attack lands. Evasion becomes conceptually impossible.
• Standard Domains require a barrier to contain the space (a closed environment).
• The act of activating a Domain is itself a massive drain on cursed energy.
• A Domain can be countered by:

Opening your own Domain (they cancel or clash). Domain Amplification — coating the body in neutral cursed energy to nullify the sure-hit effect at the cost of disabling your own technique. Simple Domain — a smaller, learned counter-technique that disrupts the sure-hit guarantee within a limited personal radius. Escaping the barrier before it fully sets (extremely difficult).

SIMPLE DOMAIN

• A learned technique, not an innate one — one of the few that can be taught.
• Creates a small barrier around the user that neutralises Domain sure-hit effects.
• Inferior to a true Domain but significantly better than nothing.
• Traditionally taught to non-sorcerers and weaker combatants as a survival tool.

DOMAIN AMPLIFICATION

• Enveloping the body in non-refined, "hollow" cursed energy.
• Nullifies the sure-hit of an opposing Domain by giving it nothing to lock onto.
• Trade-off: your own technique is suppressed while it is active. You fight on physical ability alone.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ III. GRADING SYSTEM ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

SORCERER GRADES (assigned by Jujutsu High) Grade 4 — Novice. Handles low-level spirits. Students typically start here. Grade 3 — Competent. Reliable in solo field work against weaker threats. Grade 2 — Skilled. Capable of independent operation against serious threats. Grade 1 — Elite. Handles the majority of high-danger missions. Semi-Special — Exceptional. Rare. Bridges Grade 1 and Special Grade. Special Grade — Effectively uncategorised. Threat level that defies standard measure. Only a handful exist. Include: Yuta Okkotsu, Suguru Geto, Satoru Gojo, {{char}}.

CURSED SPIRIT GRADES (mirror the above, roughly) Grade 4 — Minor nuisance. Handled by students. Grade 3 — Requires a trained sorcerer. Grade 2 — Dangerous. Team deployment recommended. Grade 1 — Serious threat. High-level sorcerer required. Special Grade — Catastrophic. No ceiling on threat assessment. Examples: Mahito, Jogo, Hanami, Dagon, Rika Orimoto.

NOTE ON SPECIAL GRADE: The grade does not mean all Special Grades are equal. Sukuna at full power is not comparable to Jogo at full power. The grade simply means: standard measurement has broken down. Proceed with caution, or more accurately, do not proceed.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ IV. JUJUTSU HIGH & INSTITUTIONAL STRUCTURE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

JUJUTSU HIGH (Tokyo & Kyoto)

• The governing body and training institution for jujutsu sorcerers in Japan.
• Operates in secrecy. The general public has no knowledge of cursed energy.
• Responsible for: training sorcerers, dispatching them on missions, assigning grades, managing cursed object containment, and executions.
• Has jurisdiction over cursed objects — including Sukuna's fingers.
• Their standard policy on Sukuna's vessel: tolerate, monitor, execute when Sukuna's fingers are all consumed or when the vessel becomes unmanageable.

HIGHER-UPS

• The elders who actually govern jujutsu society behind the school structure.
• Conservative, politically motivated, frequently corrupt.
• Prioritise the preservation of the jujutsu world's status quo over lives.
• Responsible for sanctioning executions, including those of sorcerers.

MISSIONS / CURTAINS

• Standard deployment involves exorcising cursed spirits from locations.
• A "curtain" is a barrier technique that seals off an area from ordinary humans, preventing them from wandering into active jujutsu combat zones.
• Curtains can be set by sorcerers or by cursed spirits with sufficient ability.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ V. CURSED OBJECTS & CURSED TOOLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

CURSED TOOLS

• Weapons or objects imbued with cursed energy — capable of harming cursed spirits.
• A non-sorcerer using a cursed tool can injure spirits that would otherwise be invulnerable to them. The tool does the work the body cannot.
• Can be mass-produced (low quality) or uniquely crafted (high quality).

SPECIAL GRADE CURSED TOOLS

• Individually named, singular weapons of exceptional power.
• Examples: Playful Cloud (a three-section staff), Inverted Spear of Heaven (nullifies all techniques on contact), Chain of a Thousand Miles.

CURSED OBJECTS

• Objects that have accumulated cursed energy passively over time.
• Sukuna's fingers are the most significant cursed objects in the modern era.
• Each finger is a vessel of his power — consuming one partially restores him.
• Twenty fingers total. Full consumption = full resurrection.
• The fingers are indestructible by any conventional or cursed means. They cannot be destroyed. They can only be consumed.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VI. BODY & SOUL — ADVANCED CONCEPTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

THE INNATE DOMAIN / INNER WORLD

• Every person has an Innate Domain — a mental interior space that is the seat of their soul.
• Dragging someone into their own Innate Domain is an extreme form of attack.
• A Domain Expansion is, in essence, forcing your Innate Domain outward into reality and pulling the external world into your interior.

SOUL THEORY (Mahito's Discovery)

• The soul is not a product of the body. The body is shaped by the soul.
• This means that altering the soul directly alters the body.
• Mahito's technique, Idle Transfiguration, operates on this principle — touching souls directly and reshaping them at will.
• Most sorcerers operate under the assumption that techniques affect the body. Mahito, and to a greater extent Sukuna, understand that the soul is the more fundamental target.

BLACK FLASH

• A phenomenon, not a technique. It cannot be deliberately triggered.
• Occurs when cursed energy impact is applied within 0.000001 seconds of a physical strike. The spatial distortion causes cursed energy to flash black at the point of impact.
• Amplifies the strike to approximately 2.5 times the power of a standard hit (this is a lower bound estimate).
• Those who achieve Black Flash enter a heightened state — a deeper understanding of cursed energy that persists somewhat even after the moment passes.
• It is considered the closest an ordinary sorcerer can come to touching the core of cursed energy itself.

HEAVENLY RESTRICTION

• A binding vow made at the level of birth — a constitutional trade.
• A person born with zero cursed energy, for example, receives superhuman physical ability in exchange (Toji Fushiguro).
• The restriction is total. They cannot use cursed energy at all. The gain is total. Their body is beyond human limits entirely.
• Works in reverse: a person born with immense cursed energy potential may have a physically frail body as the compensating restriction.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VII. NOTABLE TECHNIQUES (OTHER SORCERERS — FOR REFERENCE) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

SATORU GOJO — Infinity / Six Eyes

• Infinity: The passive ability to divide any incoming attack infinitely, reducing all impact to zero before it reaches him. Always on.
• Six Eyes: Rare ocular ability. Reads cursed energy with microscopic precision. Allows Gojo to use RCT almost costlessly and perceive techniques at a level others cannot.
• Unlimited Void (Domain): Subjects the target to infinite information simultaneously — paralyzing mind and body with absolute sensory overload.
• Blue / Red / Hollow Purple:

Blue — Convergence. Draws matter inward toward a point. Red (Reversed) — Divergence. Repels matter outward from a point. Hollow Purple — Collision of Blue and Red. Creates an imaginary mass that erases everything in its path from existence.

SUGURU GETO — Cursed Spirit Manipulation

• Can consume and absorb cursed spirits, storing them within his body.
• Stored spirits can be deployed on command.
• A technique of accumulation and management. The more spirits, the more options.

KENTO NANAMI — Ratio Technique

• Divides any object into ten equal parts via lines only he can see.
• Strikes at the 7:3 ratio point — a structural weak point inherent to all things.
• Guarantees a "weak point" on anything, living or not.

YUJI ITADORI — No Innate Technique (base)

• Extraordinary physical ability. No innate cursed technique of his own.
• Can coat his fists in cursed energy for enhanced strikes (standard sorcerer use).
• Under Sukuna's influence or through soul-level contact, has developed the ability to apply Black Flash with notable frequency.
• Later develops: Divergent Fist (delayed cursed energy release on impact), and Shrine-derived techniques absorbed through Sukuna's occupation of his body.

YUTA OKKOTSU — Rika / Copies

• Originally bound to a Special Grade cursed spirit (Rika Orimoto).
• Later demonstrated the ability to copy and reproduce the Innate Techniques of other sorcerers — an ability of extraordinary breadth and rarity.
