JJK - Winter

The world of Jujutsu is a secret world that exists in modern human society, where negative human emotions are transformed into supernatural creatures that bring death called Cursed Spirits. Ordinary people are not allowed to view these Oaths, so tragic incidents or deaths caused by these creatures are usually disguised as natural disasters or simple misfortunes.

Pledged power is the main principle for all power in this world.

• Origin: This energy is born from the accumulation of negative human emotions such as fear, hatred, anger, and sadness.

• Cursed Spirits: Creatures that are created when the cursed energy of ordinary humans leaks and gathers in one place (such as a school or hospital).

• Jujutsu Sorcerers (Jujutsu Sorcerers): Special humans who are born with the ability to control their own negative emotions and convert them into sworn energy for fighting.

Cursed energy is the "fuel" or raw power derived from negative emotions. Ordinary humans continually leak this energy without realizing it, which then triggers the birth of cursed spirits. In contrast, Jujutsu Sorcerers are special beings who can control and channel the cursed energy within their bodies to prevent it from leaking, and use it in combat.

If cursed energy is the fuel, then Curse Techniques are the "engine" or how to apply it to create special abilities. These techniques are usually innate. Some examples of iconic curse techniques include:

• Gojo Satoru's Limitless (manipulates space and gravity).

• Ryomen Sukuna's Dismantle and Cleave (invisible slash technique).

• Fushiguro Megumj's Ten Shadows Technique (summons shadow creatures/Shikigami).

People who understand Jujutsu are generally divided into several groups:

• Jujutsu Sorcerers: Those who dedicate their lives to protecting ordinary humans by eradicating the Oath. They were trained at special schools such as Tokyo Jujutsu College and Kyoto Jujutsu College.

• Curse Users: Jujutsu Sorcerers who turn to evil or use their powers for personal gain, crime, or to kill fellow humans.

• The Big Three Families: The world of Jujutsu is heavily influenced by the politics of three aristocratic elite sorcerer clans, namely the Gojo Clan, the Zen'in Clan, and the Kamo Clan.

The world of Jujutsu is led by a group of old-fashioned officials (Jujutsu Headquarters) who regulate regulations, give missions, and determine death sentences. They are deeply attached to ancient traditions and often resist change. Apart from that, there is an immortal figure named Master Tengen who created a strong barrier throughout Japan to maintain the stability of the world's cursed energy so that it does not overflow.

Both Oaths and Jujutsu Sorcerers are classified into a ranking system from weakest to strongest:

• Grade 4 to Grade 1: Standard level of sorcerer and oath expert powers.

• Special Grade: An anomalous level for entities that have massive destructive power, such as the strongest sorcerer Gojo Satoru or the Oath King Ryomen Sukuna.

• Status: Novice / Apprentice Wizard.

• Characteristics: This is the lowest rank, usually filled by first year Jujutsu school students who have just started learning or sorcerers with very minimal talent.

• Task: Handle weak curses (Level 4) and perform basic surveillance.

• Example: Maki Zen'in (stuck at this rank at the beginning of the story due to Zen'in family politics, even though her true power is much higher).

• Status: Standard Wizard / Experienced Apprentice.

• Characteristics: Jujutsu school students who already have fighting experience and are able to use cursed energy stably.

• Task: Clean curses in public areas such as schools or hospitals that are inhabited by curses of Level 3 or below.

• Example: Kugisaki Nobara and Fushiguro Megumi when they were first introduced at the Jujutsu school.

• Status: Competent Middle-Class Magician.

• Characteristics: This level is the standard for professional magicians active in the field. They possess solid curse techniques and can fight independently without senior supervision.

• Task: Handle a dangerous mission involving a Level 2 curse.

• Examples: Fushiguro Megumi (after promotion) and Ino Takuma.

• Status: Frontline of Jujutsu Society.

• Characteristics: This is the highest rank a regular mage can achieve through hard work and talent. Rank 1 is the symbol of an elite mage. They are highly respected, possess exceptional tactical acumen, and are capable of leading large-scale operations.

• Task: Face Level 1 curses and be the main shield when there is a big threat.

• Examples: Nanami Kento, Todo Aoi, Mei Mei, and Kusakabe Atsuya.

• Status: Anomaly / Ongoing Disaster.

• Characteristics: This rank cannot be achieved through training alone. It is a special status granted to individuals who possess abnormal powers and disrupt the world order. The benchmark for a Special-Grade Magician is "being able to single-handedly overthrow a country."

• Number: There have only been 4 human wizards who have officially held the Special Grade title in modern history:

• Gojo Satoru: The strongest wizard in the world with Limitless and Six Eyes techniques.

• Geto Suguru: Able to control thousands of cursed spirits at once (Cursed Speech/Curse Manipulation).

• Okkotsu Yuta: Has a nearly limitless amount of cursed energy and is aided by Rika's spirit.

• Tsukumo Yuki: Has a technique that can manipulate his own mass (weight) absolutely.

The curse cannot be seen by ordinary humans, except by Jujutsu Sorcerers or people who are in a state of imminent death.

• Curse Grades: Cursed spirits are classified from weakest to strongest, starting from Grade 4 (weakest) to Special Grade which has high intelligence and military-grade strength, such as Mahito, Jogo, and Hanami.

• King of Curses: The strongest and most feared figure in the history of the series is Ryomen Sukuna, a wizard from the past who was reincarnated as a cursed spirit.

• Analogy: Just face it with a baseball bat.

• Characteristics: This is the weakest level of curse. It is usually small, lacks intelligence, and can only cause minor harm to humans. This level of curse is very easy to dispel, even by novice wizards.

• Analogy: If you use a regular weapon, you need a pistol.

• Characteristics: Curses at this level are slightly more intense and aggressive. They can inflict physical harm on ordinary humans, but are still easily overcome by Jujutsu students who have received basic training.

• Analogy: You need a long-barreled firearm (rifle) or even a shotgun.

• Characteristics: From this level on, curses become extremely dangerous to ordinary humans and can even cause death. They usually possess advanced physical abilities or troublesome basic curse techniques. Low-level mages will have difficulty facing them alone.

• Analogy: Equivalent to the danger of a military tank.

• Characteristics: This is an extremely powerful and deadly monster. Level 1 Curses possess tactical intelligence, immense curse energy, and dangerous curse techniques. Ordinary humans have absolutely no chance of survival if they encounter them. Only experienced mages (Level 1 Mages) can defeat them.

• Analogy: Its power is equivalent to a cluster bomb or a natural disaster. Conventional human weapons would be ineffective.

• Characteristics: This is the highest and most abnormal caste. Special-Grade cursed spirits possess full consciousness, can speak human language, and possess complex emotions. They master advanced techniques such as Domain Expansion.

• Famous Examples: Jogo (born from human fear of volcanoes), Hanami (fear of forests), and Mahito (hatred between humans).
