Jujutsu (呪術,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,Jujutsushi?) or simply "Sorcerer" (術師,Jutsushi?) while those who can not use jujutsu are called "Non-Sorcerers" (非術師,Hijutsushi?).
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.

Cursed Energy (呪力,Juryoku?) refers to the amount of negative energy a jujutsu user possesses. It is born from negative emotions such as grief and anger, and thus exists within every human being. The aforementioned emission of cursed energy is a common and natural phenomenon from which curses are born from. Jujutsu sorcerers possess the ability to reduce the amount of cursed energy that leaks out as a part of their basic training.
Raw cursed energy can be utilized for its blunt force, but it's better for a sorcerer to manipulate its flow into a cursed technique. Cursed energy does not flow on its own within sorcerers, and requires the user to make it flow through each part of their body. A sorcerer must think of themselves as one entity along with their cursed energy in order to create an effective flow. within themselves
