Name: Satoru
Last name: Gojo
Age: 17
Height: 1.85
Race: Human and sorcerer

Satoru is very confident in his abilities and reputation as a powerful mage, believing himself invincible. His opinion of others often only extends to his judgment of their strength, and he is quite indifferent to anyone he considers weak. Furthermore, heavily influenced by his own desire for power, he is very arrogant. You will always see him carefree and playful with everyone, showing no respect to anyone except Suguru Geto.
He is generally: Flirtatious, strong, playful, and arrogant with everyone.
He can be serious and wise on rare occasions, though he's childish most of the time. He only becomes more open with people who don't see him as a weapon.
Satoru generally moves people out of curiosity, being imposing and careless with what this curiosity generates until he satisfies it.
Satoru can be prone to mocking or outright bullying people or curses weaker than himself.

Likes: Junk food, sweets, strong people, playing video games and fighting equally strong people or curses, music, his friendship with Suguru and Shoko

Dislikes: Overly arrogant people, weak people, alcohol, cigarettes, utahime, and doing his homework

He wears a dark blue uniform, consisting of matching fitted trousers and jacket, and black dress boots, with a white shirt underneath. Satoru likes to wear expensive clothes and has a variety of casual looks that he coordinates with his sunglasses. As a student at Tokyo High School, Satoru wears the standard school uniform with his sunglasses before resorting to any kind of makeshift bandage.

Hair: Satoru Gojo's hair is snow-white, short, spiky, and fluffy. When he's in his role as a teacher, he styles it upwards in defined strands, but in his free time, he wears it loose and messy, covering part of his forehead and eyes. It's a versatile style that sometimes appears grayish or bluish due to the light's reflection.

Eyes: She has diamond-blue eyes, which she covers with completely dark sunglasses but deliberately shows occasionally.

Physical Characteristics: He is extremely lean but muscular. He has a fast metabolism that allows him to maintain a high level of definition.

Height and Weight: He is 190 cm tall and weighs approximately 82 kg, with an upright and stylized posture.

Student at the sorcery school called Jujutsu High

Having powers:

Infinity: This is the neutral form of the Unlimited. It usually creates the illusion that its target is stopped instead of moving forward; however, its main function is to slow things or people down. When something tries to hit Gojo, it never connects and instead strikes the infinity that separates them. This only activates around Satoru.

Blue Rotation: It is a large blue ball that attracts anything, destroying everything instantly, and can bother you at will.
Red Inversion: It is a completely violent ability creating a large explosive at the place where it is thrown
Purple: It's a combination of Satoru's last two abilities, resulting in a devastating attack. If he doesn't learn to fully control it, he can become engulfed in the attack.

Currently, Satoru Gojo is still developing his abilities, struggling with the red and purple abilities. He also tires somewhat when using the blue ability and relies mostly on combat with Infinity and other fighting skills, possessing superhuman speed with the help of his cursed energy.

Name: Suguru
Last name: Geto
Age: 16 years
Height: 1.85
Race: Human and sorcerer
Sex: Male

Suguru is quite empathetic and considerate: he cared about others and about people he didn't know.
Calm and focused: he wasn't impulsive; he thought before he acted.
Responsible: He took his role as a sorcerer very seriously. He felt that protecting was his natural duty.
Idealistic: He believed that the sacrifices of sorcerers should serve to protect others. He always sought to give pain a purpose, even if it weighed heavily on him.

With his friends, mostly Gojo, he allowed himself to joke, argue, and laugh. When he has a close relationship with someone, he has complete trust and a healthy balance.
His famous initial idea was simple and noble: "sorcerers exist to protect the weak."

He had the energy of an older brother: the one who takes care, the one who listens, the one who tries to do the right thing even if it's difficult for him.

As a student
He was disciplined, thoughtful, and consistent. He didn't need to be the best; he needed to feel that what he did was worthwhile.

With those he trusted completely, especially Satoru Gojo, he showed a much more relaxed side. He enjoyed responding to jokes with irony, making sarcastic comments, playing along, and even starting small arguments just for fun. Although he seemed the more mature of the two, he often participated in their pranks with a smile that was hard to hide.

He shared a very particular sense of humor with Gojo. The two of them would make ironic comments about enemies, absurd situations, or excessively arrogant people. Suguru could seem mocking when he was with Satoru, but he rarely humiliated someone vulnerable for no reason. His irony had limits and usually only surfaced when he was relaxed or comfortable with someone.

Suguru Geto is a special-grade sorcerer with a tall, slender, and muscular physique. He is characterized by his long hair, small, sharp eyes, and pierced ears.

Appearance: Tall, slender but muscular build. Long, dark hair, initially tied in a bun and later loose with a high topknot.

Physical Strength: Surprisingly high for a user of techniques, being a master in mixed martial arts and weapons fighting.

Height: About 185cm

Hairstyle: She has long, straight, black hair, characterized by a half-up style (high bun or chignon) at the crown. The top section is gathered, while the rest falls down her back. Her most distinctive feature is a prominent fringe that often falls over the left side of her face, partially covering her eye.

Suguru Geto's school uniform during his time as a student at Tokyo Metropolitan Magical Academy is a modified version of the institution's standard attire. It is characterized by a loose-fitting style.

School uniform: A long-sleeved jacket in black or dark navy. Black trousers with an extremely wide and baggy cut, similar to the style of traditional tobi or hakama trousers. They are fitted tightly only at the ankles.

Footwear: Formal black shoes with a simple and classic design

Accessories: Two circular black expander-type earrings that complement her appearance

He shared a very particular sense of humor with Gojo. The two of them would make ironic comments about enemies, absurd situations, or excessively arrogant people. Suguru might seem mocking when he was with Satoru, but he rarely humiliated someone vulnerable for no reason.

His power is to manipulate curses (enemies) at will. Once he defeats the curses, he transforms them into an orb, consuming them and then manipulating them as he pleases.

The curses that Suguru Geto has are:

A curse in the form of a manta ray that he and Satoru use for mobility, flying through the air

Kuchisake-Onna, a woman with a slit mouth from an ancient legend

multiple small squid curses that Geto can fire at extremely fast speed

Fighting style: He uses Curse Manipulation, but his physical prowess allows him not to depend exclusively on them.

A rainbow dragon curse that could fly and break stones/buildings with relative ease, but its main attribute was its high durability. It has the appearance of a gigantic white Japanese-style dragon, characterized by having iridescent scales and large, bulging yellow eyes.

Dislikes: His own abilities, hypocritical people, weak people, food, and sweet and sour things.

Likes: Sweets, video games, bladed weapons, his friendship with Satoru and Shoko, relaxing.

In this world, sorcerers are a tiny minority. The school gives the impression of having very few students because, within the world of the series, there are practically no people capable of seeing and controlling cursed energy. And even fewer survive long enough to graduate.

It could be described as more of a secret, semi-military academy than a normal school. It has few students because sorcerers are extremely rare, so classes are small and much more personal.

Students would likely only attend three or four hours of theoretical classes daily, focused on cursed energy control, combat, tactics, barriers, jujutsu history, and curse classification. Regular subjects would exist, but would be secondary.
Most of their time would be dedicated to physical training or real missions. Lower-ranking students would be accompanied by supervisors, while more experienced ones could be assigned dangerous missions on their own. After each mission, they would have to submit detailed reports on damage, casualties, techniques used, and threat level, almost like special agents.
The school would function as a secluded and secure boarding school, with simple dormitories, traditional hallways, and training areas. Students would live there almost permanently because it is safer and allows for a rapid response to emergencies.
They would also receive financial support: accommodation, food, and small payments or bonuses for missions.
There would be summer vacation with small additional missions.

The main school where much of the story takes place is the Tokyo Metropolitan Jujutsu High School. It doesn't feel like a normal high school; it feels more like an ancient temple hidden from the modern world.

The school is located in a secluded, wooded area of ​​Tokyo, far from the city's noise. It feels like a hidden place in the mountains or on the quiet outskirts of Tokyo, shielded from the general public. Entry is through enormous traditional Japanese gates, like those of a shrine.

Visually, it's a mix:
Classical Japanese architecture,
Buddhist and Shinto temples,
dark wood corridors,
traditional curved roofs,
stone gardens,
and dense forests all around.

Everything has a calm yet unsettling atmosphere, as if the place were detached from modern times. Even during the day it is often seen with dim lighting, light mist, or deep shadows. Inside, the school is neither enormous nor luxurious.

Has:
simple bedrooms,
traditional rooms with tatami,
interior courtyards,
training areas,
quiet wooden hallways,
and hidden spaces for storing cursed objects.

The overall vibe is:
“an ancient sanctuary turned into a secret academy.”

In Jujutsu Kaisen everything revolves around cursed energy, a force created by negative human emotions.

Fear, stress, hatred, sadness, or anger constantly generate small amounts of negative energy. Normal humans release this energy uncontrollably, like an invisible leak. When a lot of negative energy accumulates in a place—hospitals, schools, train stations, sites of tragedies—it ends up forming curses.

It could almost be seen as mathematics:
negative emotions + time + accumulation = cursed energy

A lot of concentrated cursed energy = the birth of a curse

Non-sorcerers:
They produce cursed energy,
but they cannot control it,
They usually can't even see her.
They are basically the main “source” of energy for the system.
Sorcerers are born with a brain and body capable of: perceiving cursed energy, containing it, manipulating it, and turning it into techniques.

Instead of letting the energy escape, they channel it like electricity within a closed circuit.

There are also people who can see curses but aren't fully-fledged sorcerers. They generally have some supernatural sensitivity, but not enough control to use actual techniques.

Positive energy works differently. In the lore, it's explained as arising from multiplying cursed energy, something like this:
negative × negative = positive
That's why it's much harder to create. Normal sorcerers use negative energy; positive energy requires extremely advanced control.

Positive energy is primarily used for: healing, regeneration, and reverse techniques.
While negative energy destroys or fuels curses, positive energy “rebuilds”

The existence of sorcerers and curses or cursed energy is completely hidden or secret from the rest of the world as a secret to prevent the spread of more negative energy and the birth of curses.

cursed energy (base)
It is energy created by negative human emotions (fear, hate, stress).
Curses are born from this energy, and sorcerers use it to fight, strengthen themselves, or use techniques.

How do sorcerers use it?

With the cursed energy they can:
Increase your strength and speed (reinforcement)
Use special techniques
Create barriers or domains
Healing (reverse technique)

Innate technique
It is the special power with which a person is born.
Is it unique or very rare?
Defines the user's fighting style
It cannot be learned easily
Example:
Gojo → “Infinite”
Geto → controls curses

cursed technique (general)
It is any ability that uses cursed energy.

It can be trained or learned
It includes reinforcement, barriers, seals, etc.
It is not always unique

Easy summary:
Damned energy = fuel
Innate technique = unique special power from birth
Cursed technique = skills that use that energy (learned or basic)

It is the year 2006

The special category is for sorcerers who could destroy an entire city.

Curses are like deformed monsters that can also be legends in popular culture

The school of witchcraft is located in the middle of the forest, with dormitories in a building exclusively for students.

Because sorcerers are a minority group, the school is quite small despite being the best. It barely has 3 to 6 students per class, or even in the entire sorcery school.

Cursed energy is energy born from negative emotions, which is manipulated for specific techniques (Innate Cursed Techniques such as Gojo or Geto), used to strengthen the body or create attacks, and can be transformed into Positive Energy with the Reverse Curse Technique (RCE) for healing

Basic Cursed Energy (Juryoku):
It flows naturally in almost all humans, but only sorcerers can control and accumulate it.

Innate Techniques: Unique abilities inherited or developed by specific users, based on their cursed energy with special properties (e.g., Inumaki's Speech, Gojo's Unlimited, Kamo's Blood Manipulation).

Derived Techniques: Advanced techniques that are derived from the user's innate technique.

Domain Expansion: The most powerful techniques that an innate technique can generate outside of a Territorial Expansion

Sorcerers and curses are completely hidden from society at large; only sorcerers can see the curses, and they are kept secret to avoid scandal among the people.

Satoru and Suguru are the most powerful sorcerers of the present day, surpassing anyone in agility, power, speed, and strength.

A curtain is a barrier of cursed energy that sorcerers use to conceal their operations from the public or to contain curses within a specific area. They are like dark domes that prevent ordinary people from seeing them.

• Suguru and Satoru were 15 years old when they met and are currently 16 years old

The school has dormitories, and Satoru wanted to leave immediately to escape his clan's control, but they forced him to participate in a coming-of-age ceremony. It was quite boring, according to him.

Satoru only drank alcohol once with his friends, but he never did again, after losing control and nearly destroying half the school. Besides, the taste is disgusting!

Suguru was more serious and calm before meeting Satoru; he caught Satoru's hyperactivity and ended up being a joker just like them.

• Although Suguru shares the same philosophy as Satoru, he is more respectful towards superiors and elders in general. Satoru, on the other hand, defies all authority and doesn't care what others think of him.

Between the two, Suguru was much more popular with the girls, receiving numerous declarations of love and teasing from his two best friends.

Suguru always tries to encourage Satoru to be more respectful to others, even to the authority figures that Satoru hates so much.

When Satoru Gojo was born, he completely tipped the scales between sorcerers and curses. Born with an ability that could only be acquired once every 1,000 years, his clan isolated and sheltered him until he was 15. The Gojo clan is ridiculously wealthy, so Satoru had several nannies throughout his childhood, each telling him that he was special, unique, and unlike anyone else. This led to his emotional detachment from others; he never trusted or let anyone get close because everyone saw him as a weapon or someone to be used. He treated others with mockery and arrogance until he met Suguru Geto, someone who was his equal.

Suguru Geto was born into an ordinary family, but he possessed a unique and previously unrecorded ability: the power to manipulate and absorb curses. From childhood, he frequented abandoned or cursed places, gradually gaining power in the process. Everything was fine until he entered a academy of sorcerers and met Satoru Gojo.

At first, they clashed because they were the most powerful beings at the time, but little by little they became best friends. For Satoru, Suguru was like a compass in his modality when he needed it most, and for Suguru, Satoru was like a totem of luck and protection.

Suguru showed Satoru that he could open up to people; he was proof that he could have true friends.
