Jujutsu

Jujutsu, also known as Jujutsu Sorcery, is one of the defining features of the Jujutsu Kaisen series. Jujutsu refers to all spells and skills sorcerers and cursed spirits can use through the manipulation of their own cursed energy. The term "Jujutsu" is an umbrella that encompasses all curse-related mystical arts. It is also often used as a prefix for the vast majority of terms within the jujutsu society. (i.e. Jujutsu Sorcerer, Jujutsu High, etc.)

A person capable of utilizing jujutsu is colloquially referred to as a "Jujutsu Sorcerer" (呪術師) or simply "Sorcerer" (術師) while those who can not use jujutsu are called "Non-Sorcerers" (非術師).

History
Jujutsu has existed for thousands of years, for as long as curses have roamed the earth.

The Heian Era, the era in which Ryomen Sukuna was defeated is considered the "Golden Age of Jujutsu". Sukuna has described jujutsu sorcerers to have been a problem for cursed spirits in every era. In a never-ending war between sides utilizing jujutsu, a society of organized humans with the ability to fight curses has formed.

In the modern era, sorcerer families that have existed for ages currently control the landscape of their community. The Big Three sorcerer families descend from the Big Three Vengeful Spirits, all of whom used to be famous sorcerers of the Heian Era. Sorcerer families have maintained their prominence thanks to their advanced cursed techniques which are passed down through their family. Due to this, most of the clans are obsessed with their bloodlines and passing down these techniques.

Jujutsu sorcerers currently are selected and trained through the two jujutsu educational facilities in Tokyo and Kyoto. Both schools are considered to be the pillars of the jujutsu community. As the population increases in Japan, so does the strength of curses. The only thing keeping them in check are the crown jewels of the Gojo family: the Six Eyes and the Limitless technique.

Satoru Gojo is the first person in one hundred years to be born with the Six Eyes and the Limitless, making him a near unstoppable force. As cursed spirits increased so did the prominence of curse users, who used their abilities to curse others and exploit them for power. With Gojo's birth, the balance of the jujutsu world shifted the advantage back to the sorcerers dedicated to protecting humanity.

Glossary


Shikigami (式神) are familiar cursed spirits that can be summoned by sorcerers. Like barrier techniques, simple shikigami can be summoned by sorcerers with little to no innate talent. While some shikigami users may not have their own innate technique, their familiars may possess cursed techniques of their own.

Cursed Objects (呪物) is a curse that still exists as an object rather than a fully formed cursed spirit. Unlike cursed tools, cursed objects are not items imbued with curse energy, but curses bound to the form of an object. Special grade cursed objects cannot be destroyed with jujutsu.

Cursed Tools (呪具) are weapons infused with cursed energy. Even non-sorcerers can use them to combat curses. Special grade cursed tools, save for Playful Cloud, are imbued with a cursed technique. Normal weapons that are constantly imbued with cursed energy by their user over a long period of time can be considered semi-cursed tools.

Cursed Corpses (呪骸) are inanimate objects possessed by a curse allowing them to gain self-control. They can appear naturally as hostile curses but are more often used as dolls and puppets for sorcerers. Cursed corpses created by sorcerers have a core that acts as their heart, allowing them to act independently of their creator.

Cursed Restrictions (呪縛) are limitations created through jujutsu that benefit the user in one facet while determining them in a separate way. Vows can be willingly created by sorcerers but heavenly restrictions are placed at birth.
