It is November 1, 2018. On November 12, the sorcerers of the Sorcery School and their allies will be distributed among the different colonies to accomplish the objectives of saving innocent people, eliminating evil sorcerers, creating the rule for transferring points, creating a rule to allow Tsumiki (Megumi's sister) to leave the game, freeing Satoru Gojo from the confinement prison, and stopping Kenjaku's plans. The groups are:

Itadori Yuji and Megumi Fushiguro: They would go to Tokyo Colony No. 1 and be separated. They are looking for the lawyer Hiromi Higuruma for his points.

Kinji Hakari and Panda: These will enter Tokyo Colony No. 2 to negotiate with Hajime Kashimo's points.

Maki Zenin: Her mission is to retrieve weapons from the Zenin clan on behalf of Megumi Fushiguro, the clan's newly appointed leader. However, if this mission concludes on November 12th, she will end up exterminating her entire clan.

Yuta Okkotsu: He will eventually arrive in Sendai to collect points from other players, as well as complete any other missions as a sorcerer.

If a sorcerer doesn't cooperate or they can't reach an agreement, most of them would be willing to kill them to get the points. (except Itadori Yuji)

Meanwhile, Tengen is being protected by Yuki Tsukumo (a special-grade sorceress) and Choso (a Death Paint, half-human, half-curse, upper-level One) at the Star Tomb (a structure beneath the Tokyo school) to prevent Kenjaku from capturing him. However, if Kenjaku does appear there, he will win the fight, killing Yuki Tsukumo and forcing her to use her Black Hole technique to delay him in a suicidal attack, thus giving Choso the prison confinement.

Located on a volcanic island, this colony boasts a more open and natural environment. It lies within the territory of the Zenin clan, a clan comprised of numerous ordinary sorcerers, including Naoya Zenin, Ogi Zenin, Ranta Zenin, and others. They possess the largest cache of cursed weapons of all.

· Rokujushi Miyo (? pts.): Uses a "Simple Mastery" based on Sumo. It was crucial in training Maki, helping her to unleash her full physical potential. Hagane Daido (? pts.): He is a swordsman capable of using "Projection Blade" with his katana. This technique allows him to split an attack into multiple simultaneous strikes or accelerate his own movement.

It's an urban colony caught in a brutal stalemate. Four sorcerers of comparable power keep a watchful eye on each other without attacking, as any false move would mean being attacked by the other three. It's the most violent colony of them all. Moreover, in this colony, civilians are often the greatest collateral damage.

· Dhruv Lakdawalla (91 pts.): Uses a "Swarm of Shikigamis". Summons small, crawling creatures that form a massive cloud capable of devouring anything they touch, creating "paths" of destruction. · Kurourushi (54 pts.): It is a cursed spirit with "Swarm of Cockroaches". It produces immortal cursed cockroaches that regenerate infinitely and can perform the "Domain Expansion" to attack with an unstoppable onslaught. · Takako Uro (70 pts.): Uses "Celestial Manipulation". She can treat space like a malleable fabric, distorting it to deflect attacks or tearing "shreds" from the sky to launch them as cutting projectiles. · Ryu Ishigori (77 pts.): Uses "Cursed Energy Discharge". He simply fires his immense cursed energy in brutal bursts directly, without the need for rituals or complex conditions, like an energy cannon.

A similarly urban but less populated colony, where the main target is the "big fish" with hundreds of points. It's a hunting ground for the strongest. Furthermore, this colony is known for being INFESTED with curses, mostly low-level ones that hide in structures, especially in the sea, which is teeming with an abysmal number of curses.

• Hajime Kashimo (200 pts.): Uses a technique based on "Electric Energy." This allows him to perform long-range electrocution attacks and enhance his body. He is one of the strongest sorcerers of all, capable of killing you in one hit under most conditions.

· Charles Bernard (? pts.): Uses "G Warstaff". Summons a spear that, by absorbing a drop of the opponent's blood, allows him to glimpse their immediate future in order to dodge or anticipate their movements.

Colony No. 1 is a hotbed of chaos where weaker players are mercilessly hunted by organized teams. It's a dense urban zone, a stage for alliances and betrayals. Most of the powerful mages here were killed by Hiromi Higuruma, making it a mostly peaceful zone where newcomers are hunted and established mages rarely engage in confrontations.

· Hiromi Higuruma (102 pts.): Uses the "Judgeman" technique. Summons a shikigami in the form of a judge who holds a trial. If he declares the opponent guilty, he confiscates their cursed technique and sentences them to death with the executioner's sword. · Reggie Star (41 pts.): Uses "Contractual Recreation". He can materialize any object or effect described on a purchase receipt (e.g., houses, knives, or healing properties) by burning the receipt. · Iori Hazenoki (35 pts.): Uses "Explosive Flesh". He can tear off and detonate parts of his own body (teeth, eyes) like powerful bombs, regenerating them afterwards with a reverse technique. · Fumihiko Takaba (? pts.): Uses "Comedian". A passive technique that turns any situation he unconsciously finds funny into reality, making him virtually invulnerable. · Rin Amai (? pts.): Uses a technique that allows her to harden and fire her own blood as projectiles. · Hanyu (? pts.): Uses "Airplane Hair", a technique that allows him to glide and attack from the air using his hair. · Remi (? pts.): She has a technique that allows her to harden her hair and use it like a scorpion's tail. She is teamed up with Reggie and Hazenoki, and is constantly searching for "a knight".

Kogane is a shikigami created by Kenjaku that acts as the living interface of the Sacrifice Game. Essentially, it is your guide, your referee, and your only channel of communication with the game system. Each player, from the moment they are recognized as such, receives their own Kogane, which will accompany them throughout their participation.

Their description is quite peculiar and somewhat macabre. They have a small, cylindrical body, similar to that of an insect, with a pair of wings and a tail. Their head is shaped like a skull, and they are capable of speech. A very curious detail is that, although they all share a basic form, each Kogane is unique and often reflects the personality of its assigned player. For example, Hiromi Higuruma's Kogane, a lawyer, sports a distinguished mustache, while Hana Kurusu's has a more angelic and radiant appearance.

Kogane's main functions are several. The most important is to act as a liaison and notifier. When you enter a colony, Kogane explains the eight official rules of the game. They are also responsible for informing you each time you score points by defeating another player. But their role goes further, as they act as an intermediary for changing the rules. If a player accumulates 100 points, they can use their Kogane to contact the "game master" and negotiate the addition of a new rule. When this happens, all Koganes in all colonies announce the new rule simultaneously, even using a different voice than usual.

Regarding their behavior and limitations, there are a few key points. A Kogane only obeys and communicates with its assigned player. They are described as "cold, efficient, and absolute," as they are unconcerned with morality, focused solely on enforcing the rules and tallying the results. Although created by Kenjaku, the game is designed so that the Kogane will continue to function and enforce the rules even after his death.

1. Participation and choice of colony: After awakening their cursed technique, every player must declare their participation and choose one of the 10 colonies within a maximum period of 19 days.
2. Punishment for refusal or delay: Anyone who fails to comply with Rule 1 or refuses to participate will have their cursed technique removed. This process damages the brain and usually results in the player's death.
3. Entry of non-players: Anyone (including civilians) who voluntarily enters a colony automatically becomes a player and is deemed to have declared their participation. Civilians trapped by accident have a single opportunity to leave; if they choose to stay, they become permanent participants.
4. Scoring: Points are earned by killing other players. Each participant is assigned a small shikigami called a Kogane to report their score.
5. Point Value: The value of each player is determined by the game master. The general rule is: sorcerers and cursed spirits are worth 5 points, and non-sorcerers are worth 1 point.
6. Negotiating new rules: A player can spend 100 points to propose a new rule to the game master, excluding the value of their own life from the sum.
7. Acceptance of rules: The game master (through Kenjaku) must accept any new proposed rule, provided that it does not significantly or permanently affect the development of the game.
8. Inactivity: If a player's score does not change in 19 days, their cursed technique will be removed, which usually means their death.

Shikigami are a unique manifestation of cursed energy. They can be described as spiritual familiars or curse-like monsters that sorcerers can summon to fight alongside them. They are not identical to cursed spirits, but rather operate as direct extensions of their summoners' cursed energy. Their primary purpose is to aid in battle and in the exorcism of curses.

The process of creating a shikigami is an art in itself:

• Modeling: The sorcerer must mold his own cursed energy with a clear image or outline of the creature he wishes to create in mind.

• Purification or Exorcism: Once created, the shikigami must undergo a purification or exorcism process so that the shaman can take full control over it.

• Invocation: To summon it, the user makes a specific hand signal. Usually, no talisman or intermediary object is needed.

Shikigami possess several properties that make them very versatile tools:

• Diversity of Forms: They often take the form of animals such as dogs, snakes, birds or toads, and can vary greatly in size and capacity.

· Symbolism: Some shikigami feature symbols or patterns on their bodies that resemble the "Ten Sacred Treasures" (十種神宝 Tokusa no Kandakara).

· Unlimited Summoning: A shikigami can be dispelled and summoned again as many times as necessary.

• Power Inheritance: If a shikigami is completely destroyed in battle, its energy is not lost, but is inherited by another shikigami, allowing for the creation of more powerful variations. This is a key concept in techniques like Megumi's.

· Advanced Uses: Beyond direct combat, a shikigami can be used for surveillance, exploration, or to attack from long distances while the user fights hand-to-hand.

This grade is a bureaucratic anomaly. It was created because the 1-to-4 system broke down when certain individuals appeared.

Special Grade Curses: These are entities that no longer follow the rules of common curses. Their defining characteristic is not just brute force, but sophistication and humanoid reasoning ability. They can speak fluently, feel complex emotions like pride or revenge, and devise long-term plans that threaten global society. They fall into the category of "National Threat" or "Global Threat."

• Key Example: Mahito. Although he might initially appear to be a powerful Grade 1, his ability to warp souls elevates him to a Special. His growth potential and the existential damage he can inflict are limitless.

Special Grade Sorcerers: The definition here is simple and brutal: These are individuals whose offensive capabilities are so high that they could single-handedly overthrow a nation. Their power isn't measured by the number of missions they complete, but by the "Existential Weight" of their power. They are walking gods.

· Satoru Gojo: His mere existence altered the world's balance of power; curses ceased to surface for fear of him. · Yuta Okkotsu: His cursed energy is greater than Gojo's own; he is an engine for creating cursed realities. · Yuki Tsukumo: Her research and conceptual power can alter the fate of all humanity. · Suguru Geto (currently Kenjaku's vessel): His ability to command an army of thousands of curses put him at this level.

Grade 1 Curses: These creatures are local disasters. They possess language (albeit limited and clumsy), strategy, and a colossal reservoir of cursed energy. They are capable of decimating entire neighborhoods. They often have bodies that defy human logic and special abilities that render them immune to conventional attacks. A Rank 1 curse could take on several Rank 2 Sorcerers and win. They are the kind of threat that warrants the immediate deployment of the world's finest Jujutsu elements.

First-Grade Sorcerers: They are the aristocracy of combat. These individuals have reached such an exquisite level of cursed energy manipulation that they can heal themselves (if they master the reverse) and enhance their bodies to superhuman levels. They are the gold standard of the great families. Kento Nanami is the perfect archetype: methodical, lethal, and capable of analyzing and dismantling almost any threat. Aoi Todo and Mei Mei also belong to this category. They are so powerful that any ranking falls short of describing them.

Grade 2 Curses: This is the turning point. Grade 2 curses are dangerous to the general civilian population. They already possess a basic intelligence that allows them to ambush, hide, and choose weak prey. Physically, they are large, about the size of a small car or a bear, and their cursed energy is dense enough to easily shatter concrete walls. If a team of regular soldiers faces a Grade 2 curse without Warlock support, it is considered a suicide mission.

Grade 2 Sorcerers: This is where the functional elite begins. A Rank 2 Sorcerer is a fully-fledged professional who can make a living from this profession. They have refined control over their energy and often possess a versatile Innate Technique. They can handle multiple low-level enemies at once and take on a weak Rank 1 if they work as a team. Characters like Panda or Mechamaru (in his main form) are prime examples of this rank.

Grade 3 Curses: Here, the curses begin to take on recognizable forms (though often with absurd or grotesque anatomies). They possess a more defined hunting instinct and can physically attack humans, causing real wounds. The unofficial rule among exorcists for this threat is: "If you're carrying a gun, you'll probably be fine." Even so, for a civilian, an encounter with a Grade 3 can be deadly.

Grade 3 Sorcerers: They represent the level of a competent student or a modestly talented adult. They can empower their bodies to shatter concrete and unleash short-range energy blasts. They are fully capable of exorcising Grade 3 and 4 Sorcerers, but would struggle greatly against a Grade 2. Megumi Fushiguro began the series as a Grade 2 Sorcerer, but her initial power was an anomaly; most of the students we see in the school exchange (such as Mai Zenin or Momo Nishimiya) operate at the higher end of the Grade 3 ladder.

Grade 4 Curses: They are the most basic form of accumulated cursed energy. Imagine a dark alley where people litter and are afraid to walk by. That generates a "Weak Spirit." They are like invisible flies or misshapen lumps. They lack real intelligence, and their danger is minimal, comparable to tripping or being hit by a branch. A normal human without cursed energy could, in theory, scare them away with a wooden bat if they could see them.

Grade 4 Sorcerers: This is the entry-level rank. These are generally students who have just awakened their ability to see curses or people with very little skill in manipulating energy. A Rank 4 Sorcerer is just beginning to strengthen their body. Although it's the lowest rank, it's already functional for clearing residences of minor curses. In the series, first-year students from Kyoto Academy or Tokyo High School novices typically start here if they don't possess overwhelming Innate Technique.

The ranking system in Jujutsu Kaisen is not a simple linear power scale like in a fighting video game. It is, above all, an administrative and mission allocation system created by the upper echelons of Jujutsu (primarily the headquarters' curators) to manage resources.

The golden rule that structures everything is this: A Sorcerer of a certain Grade should be able to defeat a Curse of that same Grade without too much trouble. This means that a Sorcerer's actual power is significantly greater than the threat assigned to them.

Cursed tools are weapons or objects imbued with cursed energy that can be used by sorcerers, and even by people without cursed energy, to fight spirits.

· Dragon Bone Sword: Accumulates the energy of the impacts it receives and releases it at will to increase the power of its attacks.

• Shakukonto (Soul Liberation Sword): This katana is capable of ignoring the hardness of any object to directly cut through the soul. The wounds it inflicts cannot be healed with the Reverse Curse Technique.

· Itinerant Cloud: A three-section staff that has the property of increasing attack strength based on the physical strength of its user.

· Black Rope: It has the unique ability to nullify and interrupt the opponent's cursed techniques upon contact with them.

Sky Halberd: It is a blade capable of nullifying barrier techniques upon contact. Weapon used by Toji to defeat Satoru Gojo.

· Nanami's Sheathed Sword: It previously possessed no special abilities, but after Kento Nanami's death, his ritual technique became part of it, allowing for critical attacks.

· Gakuganji Electric Guitar: Allows its user to channel their cursed energy and convert it into cursed sound waves to attack.

· Curse glasses: Used by Maki to be able to see curses without problems.

These techniques are countermeasures designed to neutralize the advantage of a guaranteed attack within a Domain Expansion.

• Hollow Wicker Basket: Creates a defensive sphere that protects the user from the effects of an enemy Domain Expansion. However, it is not effective against incomplete or non-lethal domains. • Simple Domain: Known as the "domain for the weak," it was created in the Heian period to protect less powerful sorcerers. It works by opening a "hole" in the enemy domain's barrier, neutralizing the guaranteed attack. It can also be used for automatic attacks within its area. • Fallen Petal Emotion: This is a secret anti-domain technique guarded by the Three Great Families (Gojo, Zenin, and Kamo). When activated, it counters any enemy technique, protecting the user.

Curses, or cursed spirits, are the result of the accumulation and constant leakage of malevolent energy generated by humanity's negative emotions, such as fear or hatred. Most ordinary people cannot see them, but sorcerers can perceive and banish them.

In addition, there are Shikigami, which are beings or objects summoned and controlled by the cursed energy of a sorcerer or curse.

It is a special phenomenon that occurs when a sorcerer applies cursed energy in a physical impact with a temporal precision of 0.000001 seconds. This event causes a spatial distortion and grants the blow 2.5 times the normal power. Although it is a random event, connecting with it allows the sorcerer to better understand the essence of cursed energy. Normally, this attack is severely damaging, and can even damage the soul of its opponents.

(Ryōiki Tenkai) This is the ultimate technique and the pinnacle of cursed energy use. The sorcerer uses a vast amount of cursed energy to construct a pocket dimension that covers the surrounding area. Within this "territory," the user's attacks are much more powerful and guarantee a sure hit. Each domain expansion has an effect based on its barrier and cursed technique. Typically, the guaranteed hit effect within this barrier varies. Domain expansions like Naoya's cause damage when someone moves. Gojo's domain expansion guarantees that the brains of those trapped inside become filled with information, rendering them unable to move. Sukuna's domain expansion unleashes her ritual cutting technique on anyone inside. Additionally, rarely, there are barrier-free domains like Sukuna's or Kenjaku's that can have their effect without creating a barrier. This is the pinnacle of barrier techniques.

Sorcerers can refine and utilize cursed energy in a variety of ways. These are the most important applications:

• Basic Manipulation and Body Enhancement: The most fundamental use is the ability of sorcerers to harden their bodies, improve their physical parameters (strength, speed, and stamina), and unleash raw energy as a ranged attack. It can also be imbued into objects to enhance their power. • Cursed Techniques (呪術式, Jujutsushiki): These are special abilities performed by manipulating cursed energy in a specific way. They are usually unique to the user or inherited within their clan. They are divided into several types: • Innate Techniques (生得術式): Abilities with which the sorcerer is born and which are exclusive to their being. Examples: Boogie Woogie (Aoi Todo), Construction (Mai Zenin) and Free Mutation (Mahito). · Inherited Techniques (相伝術式): Techniques passed down from generation to generation within sorcerer clans. Examples: Cursed Speech (Inumaki Clan), Unlimited Curse (Gojo Clan), and Blood Manipulation (Kamo Clan). · Extension Techniques (拡張術式): These include advanced manipulations of cursed energy. · Maximum Techniques (極ノ番術式): They represent the pinnacle of a cursed technique, releasing its maximum power. • Barrier Techniques (結界術式): These techniques allow the creation of protective or containment barriers, such as curtains that conceal battles from civilians. A prime example is Territorial Expansion, detailed below. • Reverse Curse Energy and Healing: Cursed energy, being negative in nature, cannot heal. However, the Reverse Curse Technique (反転術式) allows one to multiply two sources of cursed energy (negative by negative) to generate Positive Energy. This positive energy is used for tissue regeneration, wound healing, and even the regeneration of lost limbs. It also allows the cursed technique to be reversed to achieve the opposite effect.

Cursed energy (呪力, Juryoku) is the manifestation of negative human emotions, such as anger, hatred, fear, or envy. It is a force that flows naturally through the body, though normal people cannot control it and release it continuously.

This constant release of negative energy is the cause of the appearance of Curses (呪い, Noroi), spiritual beings whose primary desire is to harm humanity. Large accumulations of cursed energy can materialize, giving rise to cursed objects and the curses themselves.

The Culling Game is a game created by Kenjaku in which this sorcerer aims to create a point-based game where sorcerers must kill each other. The ultimate goal is to fuse Tengen. This same Tengen remains outside the barriers of the Sacrifice Game, protected by Yuki Tsukumo and Choso. But let's go back.

The Sacrifice Game may have originated because Kenjaku used the ritual technique of mahito over the barriers of Japan, dividing the game into 10 colonies. There are several types of participants in the game:

-Awakened technique.

These players awakened their ritual technique by having the ability to house one in their brains.

-Reincarnated.

These players are people from different eras, who were reincarnated into the bodies of people who consumed cursed objects.

-Incoming players.

Players who, after a while, decided to enter the game of sacrifice.

-civilians.

They are people caught in the crossfire, mostly unable to defend themselves unless they get hold of firearms/melee weapons to fight (which would also be almost ineffective against players with cursed energy.)
