Jujutsu Kaisen

Magi (呪術師, jujutsu-shi, also called sorcerers, shamans, or warlocks) are people trained and employed by magical schools to find and dispel curses.

Key characteristics of mages:

Working with cursed energy. Mages can sense, control, and harness cursed energy—the foundation of magic in this world. They restrain its flow to prevent the creation of new cursed spirits.
Official training and registration. All recognized mages undergo training at magical academies (such as Tokyo or Kyoto) and are registered as curse-fighting experts.
Physical and mental differences. The brains of mages are structured differently than those of ordinary people, allowing them to interact with cursed energy.
Special techniques. Each mage has a unique magical ability—a technique. It can be:
hereditary (passed down through clans, for example, Megumi Fushiguro’s “Ten Shadows”);
congenital (present from birth);
acquired (develops during training).
Ranking system. A mage's power is assessed by ranks, from 4th (the weakest) to Special (the strongest). A higher rank grants access to more challenging missions and greater rewards.

What do magicians do:

fight curses of varying levels of power;

carry out missions to protect ordinary people;

study and improve magical techniques;

train new magicians in technical schools;

participate in the political and organizational life of the magical community.

Examples of magicians:

Satoru Gojo is a special-rank mage, a teacher at Tokyo Technical High School, and the most powerful mage of our time. He masters the "Infinity" and "Six Eyes" techniques.

Yuji Itadori is a first-year student. Originally an ordinary human, he became Sukuna's vessel, granting him access to immense power.

Megumi Fushiguro is a first-year student and a first-rank mage. She uses the Ten Shadows technique, summoning shikigami (spirits).

Suguru Geto is a former special-rank mage. He mastered the technique of collecting and manipulating curses, but later became a renegade.

Shoko Ieiri is a doctor at the technical school and a first-rank mage. She specializes in healing using cursed energy (healing at the cellular level).

Common stereotypes about magicians:

they are considered crazy due to the specific nature of their work and contact with curses;

They say that they become disconnected from ordinary life and lose the ability to empathize;

In clans of magicians, traditions are often placed above family ties, which exacerbates isolation.

There are two magical colleges—Tokyo and Kyoto. I'll explain this in more detail using Tokyo as an example—it plays a key role in the plot.

Official name and status.

Tokyo Metropolitan Technical School of Magic (東京都立呪術高等専門学校, Tōkyō Toritsu Jujutsu Kōtō Senmon Gakkō).

It operates under the guise of a private religious school, but in reality it is the educational and administrative center of the magical community of Japan.

It is located on the outskirts of Tokyo, high in the mountains (at the foot of Mount Mushiro).

A complex of buildings in the traditional Japanese style: statues of deities, shrines, torii gates.

The area is hidden behind a powerful protective barrier maintained by Master Tengen (who lives under the school, in the Star Tomb).

On the territory: classrooms, dormitories, training grounds, an inner courtyard, a morgue for fallen mages, and isolation cells.

Management

Director: Masamichi Yaga (former, deceased).

Subordinate to the Magic Headquarters (the highest governing body of the magical community).

Administrative Center: This is where key decisions in the magical world are made.

Base of Operations: Mission coordination, storage of dangerous cursed items (including in the Star Tomb).

Knowledge repository: archives, methods, barriers and artifacts.

Kyoto Magic College is the second major center of learning. It is more conservative than Tokyo Magic College and has a long-standing rivalry with it. Notable students include Momo Nishimiya, Noritoshi Kamo, and Utahime Iori.

Ranks are a classification system for the power of mages, cursed spirits, and cursed tools and objects. I'll explain the ranking system for mages in detail.

Mage Rank Levels

Fourth rank (Yonkyū) is the lowest level. It is awarded to inexperienced or relatively weak mages.

Example: Maki Zenin (rank was awarded due to the bias of the Zenin clan, not actual strength).
Third rank (Sankyū) is an intermediate level, often awarded to students of magic schools.

Examples: Nobara Kugisaki, Mai Zenin.
The semi-second rank (Jun Nikyū) is an intermediate level between the third and second ranks. Little is known about it.

Example: Panda (sophomore at Tokyo Technical High School).
Second rank (Nikyū) is above average. Reaching this rank during training is considered a sign of talent.

Examples: Megumi Fushiguro, Takuma Ino.
Jun Ikkyū (Jun Ikkyū) is a transitional stage on the path to Rank I. It is earned after successfully completing missions accompanied by a Rank I mage.

Examples: Toge Inumaki, Noritoshi Kamo, Kokichi Muta, Utahime Iori.
First rank (Ikkyū) is the highest level attainable naturally. Mages of this rank are the pillars of the magical community.

Examples: Kento Nanami, Mei Mei, Aoi Todo, Atsuya Kusakabe, Masamichi Yaga.
Special First Rank (Tokubetsu Ikkyū) is a rank for mages outside the standard ranking system. Their power is roughly equivalent to that of a first rank, but they operate autonomously.

Example: Naobito Zenin (head of the Zenin clan).
A special rank (Tokkyū) is an exceptional level of power, beyond the usual classification. Such mages possess unique abilities and colossal power.

Examples: Satoru Gojo, Suguru Geto, Yuki Tsukumo, Yuta Okkotsu.

How does rank promotion work?

To increase the rank, a mage must:

Receive a recommendation from a higher-ranking mage (at least two recommendations are required for rank 1).
Submit a request for promotion to a high-ranking person in the magical community (e.g. Kyoto College Director Yoshinobu Gakugandzi).
For rank 1: Complete several missions accompanied by a rank 1 mage (not the one who gave the recommendation).
Obtain a semi-first rank.
Complete a first-tier curse exorcism mission on your own.
Based on the mission result, a decision is made to assign the first rank.
Key principle: a mage's rank is determined by their ability to defeat curses of the corresponding level. For example, defeating a first-tier curse can lead to promotion to first-tier.

Why are ranks needed?

Mission difficulty determination. Mages receive missions appropriate to their level.
Pay. The higher the rank, the greater the reward for completing dangerous missions.
Hierarchy in society. Ranks help structure magical society and assign roles.
Threat Assessment. The system allows you to quickly assess the strength of a mage or curse in a critical situation.
