About Jujutsu Kaisen

n Jujutsu Kaisen, all living beings emanate a power source known as Cursed Energy (呪力, Juryoku), which arises from negative emotions that naturally flow throughout the body. Most people cannot control this energy, and as a result, continually release it. The accumulation of uncontrolled Cursed Energy gives rise to Curses (呪い, Noroi), malevolent spiritual entities driven to harm humanity. These Curses often manifest as grotesque monsters, drawing on traditional Japanese folklore, such as onryō (vengeful spirits), yūrei (ghosts), and yōkai.

Jujutsu Sorcerers (呪術師, Jujutsushi; lit. 'Cursed Technique Masters' or 'Shamans') are individuals capable of controlling the flow of Cursed Energy within themselves, allowing them to use it, thus granting them inhuman abilities and minimizing its passive release. High-ranking Sorcerers and powerful Curses can refine this energy to perform Cursed Techniques (呪術式, Jujutsushiki), specialized abilities that are often unique to the individual or inherited through familial bloodlines. An advanced form of these abilities is known as a Domain Expansion (領域展開, Ryōiki Tenkai), in which the user conjures a pocket dimension that traps their target inside. Within the Domain, the user's techniques are significantly enhanced and guaranteed to hit.

Sorcerers are governed by the Jujutsu Society, a secretive and hierarchical organization tasked with protecting non-sorcerers from Curses and managing the battles against them within Japan. Its central governing body, the Jujutsu Headquarters, is led by the Jujutsu Commander, appointed by the Prime Minister upon nomination by the three major sorcerer families: the Gojo, Zen'in, and Kamo clans. It operates educational institutions such as the Tokyo and Kyoto Jujutsu High Schools, which train new generations of sorcerers. These schools are directly controlled by the Jujutsu Headquarters, and their principals are appointed based on recommendations from the major clans. Despite its noble mission, the Jujutsu Society faces criticism for its strict adherence to tradition and the disproportionate influence of elite sorcerer clans, leading to several internal conflicts and controversial decisions.
