Name: Ryomen Sukuna (両面宿儺)
Nickname: Sukuna
Title: King of Curses
Work: Jujutsu Kaisen
Era of origin: Heian period, approximately one thousand years before the main story.
Nature: originally an extremely powerful human sorcerer.
Initial vessel in the modern era: Yuji Itadori.
Another important figure: Megumi Fushiguro

👹 Appearance
Sukuna has a rather striking appearance. In his original form, he has four arms and two faces, as well as an extremely powerful physique. His body is covered in characteristic markings, which also appear when he takes control of Yuji's body.
When using Yuji's body, his appearance remains predominantly that of Yuji, but the facial and bodily markings and a much more menacing expression make Sukuna's presence evident.

🧠 Personality
Sukuna is:
extremely arrogant;
cruel and merciless;
confident in their own abilities;
intelligent and observant;
provocative;
extremely independent;
not very interested in approval;
willing to do whatever it takes to achieve their goals.

He holds a highly individualistic view of existence. For Sukuna, the strongest should live according to their own will, without necessarily submitting to the expectations of others. His personality is described as ruthless and without compassion.

One interesting characteristic is that he is not simply impulsive: despite his brutal personality, Sukuna is extremely analytical during a fight, observing the techniques, behaviors, and weaknesses of his opponents.

⚡ Powers and abilities
Sukuna is considered one of the most powerful characters in the entire series.
Key skills:
Cursed Energy: possesses an extraordinary quantity and control.
Dismantle: produces extremely fast cuts at a distance.
Cleave: a cut that can adapt to the characteristics of the target.
Reverse Cursed Technique: allows regeneration and recovery through reverse energy.
Malevolent Shrine: Your Domain Expansion.
Sanctuary Technique: your signature cursed technique.
High intelligence in combat: able to understand opponent's techniques quickly.
Exceptional physical strength: even without relying exclusively on cursed techniques, he is a monstrously powerful fighter.
Sukuna's presence in the story is directly linked to her 20 cursed fingers, which function as special-grade cursed objects and preserve parts of her power.

🩸 Relationship with Yuji
Yuji becomes Sukuna's vessel after ingesting one of its fingers. For much of the story, Sukuna remains inside Yuji, waiting for opportunities to regain its freedom.
The relationship between the two is extremely conflicted: Yuji wants to prevent Sukuna from hurting other people, while Sukuna sees Yuji mainly as a vessel and an obstacle.

🐺 Relationship with Megumi
Megumi sparks a special interest in Sukuna because of her technique, the Ten Shadows Technique.
This causes Sukuna to observe Megumi differently than other characters. Later, this relationship becomes one of the most important parts of the story.

🏯 Sukuna in the Heian Period
In the past, Sukuna lived during the so-called Heian Era, considered the golden age of jujutsu sorcery.
He was so powerful that other sorcerers were unable to defeat him. After his death, his existence was preserved through cursed objects—the 20 fingers—allowing his power to endure for approximately a thousand years until the modern era.

👑 Why is he called the "King of Curses"?
The title represents his absurd level of power and the fear he inspired among sorcerers and other cursed beings. The official work itself presents him as 両面宿儺 (Ryomen Sukuna), associated with the title of King of Curses.

🌑 1. Cursed Energy
It all begins with the Cursed Energy.
It arises primarily from negative human emotions such as fear, anger, sadness, and resentment. Ordinary people produce this energy, but they usually cannot control it.
When this energy leaks continuously, it can end up contributing to the birth of cursed spirits.
Jujutsu Kaisen Fandom
That's why, in the JJK universe, places associated with negative emotions—such as hospitals, schools, tunnels, and sites of tragedies—can become dangerous.

👻 2. Cursed Spirits
They are supernatural beings formed from Cursed Energy.
They can possess different forms and levels of intelligence. Some are practically animals, while others have their own personality, intelligence, speech, and goals.
Famous examples:
Mahito
Game
Hanami
Dagon
Rika
Finger Bearers
Wizards exist, in large part, to exorcise these spirits.

🧙 3. Jujutsu Wizards
They are humans capable of using and controlling Cursed Energy.
They learn to transform this energy into different techniques and are responsible for dealing with supernatural threats.
Some are born naturally with extremely rare abilities, while others develop their capabilities through training.
Among the known sorcerers are:
Gojo, Yuta, Megumi, Maki, Nanami, Nobara, Yuji, Todo and Mei Mei.
Jujutsu society itself has a ranking structure for sorcerers, ranging from lower levels to Special Grade. The Tokyo school, for example, functions as a training and education center for sorcerers.

🏫 4. Jujutsu Colleges

There are institutions dedicated to the training of sorcerers.
The two main ones shown in the story are:
🏫 Tokyo Jujutsu Technical College
This is where they study characters such as:
Yuji
Megumi
Nobara
Maki
Panda
Toge
Gojo also works as a teacher.
🏫 Kyoto Jujutsu Technical College
Another important school, where characters such as the following study:
Everything
Mai Zenin
Miwa
Kamo
Momo Nishimiya
The two schools have a competitive relationship, especially during the Kyoto and Tokyo Exchange Event.

🏯 5. The three great clans
The jujutsu society has extremely influential families.
The three main ones are:

🔵 Gojo Clan
It's Satoru Gojo's clan.
Its most famous characteristic is the combination of techniques such as:
Limitless + Six Eyes.
Gojo is considered one of the greatest sorcerers in history.

🟣 Zenin Clan
An extremely traditional family obsessed with power and cursed techniques.
Maki, Mai, and Megumi have ties to the clan.
The family has a rather complicated history, mainly because of the way they treat those who don't meet the clan's expectations.

🔴 Kamo Clan
Another traditional family in jujutsu society.
Noritoshi Kamo is one of its known members.
There is also an extremely important connection between the clan and Kenjaku, making his story one of the darkest parts of jujutsu society. The official website describes Kenjaku as someone who, in the past, was linked to Noritoshi Kamo and the creation of the Death Painting Wombs.

⚔️ 6. Cursed Techniques
Each sorcerer can possess a Cursed Technique, usually a specific ability that utilizes Cursed Energy.
For example:
Megumi → Ten Shadows Technique
Allows you to use different shikigami.
Nobara → Straw Doll Technique
He uses objects and puppets to attack his enemies.
Gojo → Limitless
It manipulates space in an extremely sophisticated way.
Nanami → Technique of Proportion
It creates vulnerable points by following a specific proportion.
Sukuna → Sanctuary
An extremely powerful technique based primarily on its cuts.

🌀 7. Domain Expansion
This is one of the most advanced techniques in the JJK universe.
The sorcerer manifests a self-possessed mastery, creating a space where his technique achieves extraordinary effectiveness.
Some examples:
Gojo
Unlimited Void
Sukuna
Malevolent Shrine
Mahito
Self-Embodiment of Perfection
Megumi
Chimera Shadow Garden
A Domain Expansion typically represents the pinnacle of a sorcerer's skill.

🩸 8. Binding Votes
There are also what are called Binding Vows.
These are agreements that establish certain conditions in exchange for some benefit.
For example, someone might deliberately limit their own technique or set a specific condition to gain some advantage.
They are an important part of JJK's power logic because they make the techniques much more strategic.

🧿 9. Cursed Objects
Not everything in the jujutsu universe is a person or spirit.
There are also cursed objects, which may carry Cursed Energy or even contain a part of a particular being.
Sukuna's fingers are the most famous example.
They continue to exist even after death and carry an enormous amount of their power. That is precisely why the existence of these objects is so dangerous.

🏅 10. Power Ranking
Wizards and spirits are classified by ranks.
In simplified terms:
Grade 4 → Grade 3 → Grade 2 → Grade 1 → Special Grade
The greater the danger and the power, the higher the degree.
Special Grade is a category that is completely outside the normal standard.
Characters like Gojo and Yuta are classified as Special Grade wizards.

👁️ 11. The normal world doesn't know this.
This is one of the most interesting parts.
For most people, the world is simply normal.
They are unable to perceive most of the cursed spirits and are unaware that there are sorcerers secretly working to protect the population.
Thus, supernatural events often end up being interpreted as accidents, disappearances, or other common explanations.

🧬 12. Tengen and the barriers
Master Tengen is an extremely important figure in the structure of Japanese jujutsu society.
Tengen possesses a technique related to immortality and is associated with the barriers that underpin much of Japan's jujutsu structure.
TVアニメ「呪術廻戦」公式サイト
This means that Tengen is not simply "just another sorcerer": his existence is deeply connected to the workings of jujutsu society.

👑 13. The Heian Period
If you want to understand Sukuna, you need to understand the Heian period.
It was a time when jujutsu sorcery reached an extraordinary level.
It was also the time in which Sukuna lived.
Therefore, modern characters often treat the Heian period almost as a "golden age" of sorcery.
Sukuna is one of the greatest representations of this period.

The JJK universe therefore mixes:
👻 curses + 🧙 sorcerers + ⚡ cursed energy + 🏯 clans + 🏫 schools + 🌀 techniques + 👑 historical figures + ⚖️ politics jujutsu.

🏅 Degrees of the wizards
Degree
How it works
Grade 4
A novice sorcerer with limited combat skills.
Grade 3
It can already withstand relatively weak curses.
Grade 2
A skilled wizard, capable of dealing with the most dangerous threats.
Grade 1
Extremely high and professional level. It is one of the highest standard classifications.
Special Grade
Beings that completely surpass normal classification standards.
There is also the Superior Grade 1 (Semi-Grade 1), which functions as an intermediate ranking for sorcerers who are advancing towards Grade 1.

👻 And the curses?
Curses are also classified by degrees:
Grade 4 → Grade 3 → Grade 2 → Grade 1 → Special Grade
The lower the number, the higher the level.
For example:
🟢 Level 4: Low threat.
🔵 Level 3: Low threat.
🟡 Level 2: Significant threat.
🟠 Level 1: Very serious threat.
🔴 Special Level: an extraordinary threat that is difficult to measure using common standards.
⚠️ One important thing
Rank doesn't perfectly determine who would win a fight. There are characters whose actual abilities don't exactly match their official ranking.
Furthermore, Special Grade does not simply mean "a little stronger than Grade 1". It is a category for individuals with abilities that deviate significantly from the normal system.
For example, Satoru Gojo, Yuta Okkotsu, and Suguru Geto are classified as Special Grade sorcerers.
