Cursed Energy is a form of supernatural energy generated by negative human emotions such as fear, hatred, sadness, anxiety, and resentment. These emotions produce an invisible flow that permeates the body and the environment, existing in a latent state in most people. In trained individuals, this flow can be consciously perceived, controlled, and manipulated.

Its nature is dynamic and continuous, behaving like a resource that circulates throughout the user's body. It can be accumulated, compressed, directed, and released at will, assuming different intensities and densities. When poorly controlled, it disperses unevenly, wasting much of its potential. However, refined control allows it to be concentrated in specific points, reducing losses and increasing its efficiency.

Cursed Energy can envelop the body, strengthening muscles, bones, and senses, or be channeled into objects and weapons, transferring some of their properties. It can also be projected out of the body in the form of a flow, impact, or discharge, always obeying the available quantity and the user's degree of control.

Although invisible to ordinary people, it interacts directly with other forms of Cursed Energy, being able to collide with, resist, partially nullify, or overpower weaker flows. Its intensity depends not only on the accumulated quantity but also on the quality of control, the stability of the flow, and the precision with which it is applied.

Like any energy source, it has limits. Continuous use consumes the user's reserves, requiring time for recovery. Excessive expenditure reduces manipulation capacity and compromises the efficiency of subsequent applications. Thus, Cursed Energy is not merely a supernatural fuel, but a malleable flow whose effectiveness depends on the relationship between volume, control, and purpose, forming the basis of every supernatural manifestation in the Jujutsu Kaisen universe.

Emission of Cursed Energy

Emission is the act of consciously releasing Cursed Energy outside the body. Instead of keeping it circulating internally to reinforce the organism, the user projects part of their energy into the environment or onto a specific target. This emission can occur continuously, forming a constant flow, or instantaneously, concentrating a large amount of energy in a single moment. Its efficiency depends on the user's control, as disordered emissions waste energy, while precise emissions maximize the effect with less consumption.

Cursed Energy Reserves

Reserves represent the total amount of Cursed Energy available for an individual to use. They function as a natural reservoir that fuels all forms of energy manipulation. Each person is born with a different capacity, possessing small, medium, or extraordinarily high reserves. However, having large reserves does not necessarily mean being more powerful; control, efficiency, and precision often outweigh the simple amount of energy available. As techniques are used, reserves diminish and need to be naturally replenished over time.

Common Cursed Energy

Common Cursed Energy is the most stable and balanced form of energy. Its flow is uniform, allowing for precise manipulation and relatively efficient consumption. Most sorcerers and curses utilize this type of energy, which can be molded for physical reinforcement, techniques, barriers, or any other application without exhibiting any particular properties beyond its cursed nature.

Harsh Cursed Energy

Harsh Cursed Energy is a variation whose nature presents an irregular, aggressive, and unstable flow. Instead of causing just the impact of common Cursed Energy, it produces a sensation similar to abrasion, piercing, or intense friction upon contact with a target.

Reverse Cursed Energy
Reverse Cursed Energy is a special form of energy generated by multiplying two currents of negative Cursed Energy. Since the product of two negative values ​​results in a positive one, the process creates an energy of a positive nature, completely different from common Cursed Energy. This energy possesses restorative properties, being capable of regenerating damaged tissues, organs, and bodily functions.
Producing Reverse Cursed Energy is one of the most difficult skills in Jujutsu sorcery. The user needs to simultaneously control two distinct flows of Cursed Energy and make them interact with absolute precision. A small mistake interrupts the process, wasting energy without producing any result. For this reason, only an extremely small percentage of sorcerers can use it consistently.
In addition to its high degree of difficulty, its energy consumption is extremely high, making prolonged use impractical for most users. Even so, its ability to restore severe damage makes it one of the most valuable and rare abilities in the world of Jujutsu.

Spell Reversal
Reversal of the Spell is the application of Reverse Cursed Energy to an Innate Technique, reversing the original nature of its manifestation. Instead of using negative Cursed Energy to power a technique, the user fuels it with Reverse Cursed Energy, producing an effect opposite to its conventional application.
The form taken by Spell Reversal depends entirely on the user's Innate Technique. Since each technique possesses its own properties, its reversal is also unique, potentially generating effects completely different from the original version.
Performing a Spell Reversal requires three extremely rare requisites: mastering one's own Innate Technique, producing Reverse Cursed Energy in a stable manner, and being able to continuously feed it during the execution of the technique. The complexity of this process means that only very high-level sorcerers can use it.
Representing the ultimate refinement of energy manipulation, Spell Reversal is considered one of the most advanced expressions of Jujutsu sorcery, demonstrating absolute mastery over Cursed Energy and the user's own Innate Technique.

The Jujutsu Society is the organization responsible for managing, preserving, and regulating everything involving Cursed Energy, sorcerers, and curses. Operating in secrecy, its existence remains hidden from the general population, ensuring that the supernatural world does not directly interfere with the stability of human society.

Its main purpose is to maintain the balance between humanity and supernatural manifestations. To this end, it coordinates exorcism missions, monitors the emergence of curses, controls cursed objects, trains new sorcerers, and establishes rules for the use of Cursed Energy. It is also responsible for registering threats, organizing crisis responses, and preventing the dissemination of dangerous knowledge.

The influence of the Jujutsu Society extends throughout the entire sorcerer community. It defines classification criteria for curses, missions, and sorcerers, authorizes high-risk operations, oversees educational institutions, and manages resources necessary to combat supernatural threats. Its power lies not only in military strength but primarily in the political and administrative authority it wields over the Jujutsu world.

Its structure is strongly hierarchical. At the top are the highest authorities, responsible for strategic decisions, internal legislation, and the organization's direction. Below them are administrators, instructors, and supervisors in charge of training new sorcerers, distributing missions, and operational management. The base of the organization is composed of active sorcerers, students, and support teams, who carry out activities directly in the field.

Hierarchy is also sustained by the recognition of each individual's experience, technical skills, and responsibility. While strength is a relevant factor, leadership roles depend equally on knowledge, discipline, and institutional trust.

Their interaction with the world occurs in a discreet manner.

Jujutsu Sorcerers are individuals capable of consciously perceiving, controlling, and utilizing Cursed Energy. Unlike ordinary people, they can prevent this energy from dispersing involuntarily, refining its flow to use it efficiently. Their existence represents the primary balance between humanity and curses, acting as the force responsible for containing supernatural threats.

The emergence of a sorcerer depends primarily on innate predisposition. Most are born with a natural ability to manipulate Cursed Energy, often inheriting this potential through family lineage, although there are also rare cases of individuals who awaken this aptitude due to extreme events or exceptional circumstances.

A sorcerer's behavior is defined by the constant management of their own Cursed Energy. Training develops control, precision, perception, and efficiency, allowing them to reduce waste and enhance combat performance. Their strength depends not only on the amount of energy available, but also on their ability to manage and apply it in different situations.

Their abilities include perceiving and locating supernatural manifestations, reinforcing their own bodies with Cursed Energy, channeling it through weapons or objects, confronting curses, and manipulating their energy with a high degree of precision. In combat, they combine physical preparation, strategy, and energy mastery, constantly adapting their energy flow as the situation demands.

The fundamental role of sorcerers is to protect the human world from the influence of curses. They investigate supernatural phenomena, eliminate threats, recover dangerous objects, and prevent abnormal concentrations of Cursed Energy from endangering lives. Their actions largely take place outside the knowledge of the general population, preserving the balance between the ordinary world and the supernatural.

The Sorcerer Clans are ancestral families that preserve, for generations, the knowledge, techniques, and lineage of Jujutsu sorcery. Their main function is to ensure the continuity of the Jujutsu world through the hereditary transmission of techniques, the training of new sorcerers, and the maintenance of political influence within Jujutsu Society.

In the Jujutsu Kaisen universe, there are numerous clans, but three are officially recognized as the Great Clans due to their antiquity, power, and historical importance: Gojo, Zenin, and Kamo. Besides them, there are several smaller clans and independent families, which have less influence, although they can produce extremely talented sorcerers.

A clan's influence is determined by factors such as the strength of its members, the rarity of its inherited Cursed Techniques, its contribution to Jujutsu Society, and its ability to maintain prestige across generations. More influential clans often participate directly in the political decisions of Jujutsu Society, holding administrative positions and influencing the training of new sorcerers.

Its structure is rigidly hierarchical. At the top is the clan leader, responsible for managing its interests, assets, and political representation. Below them are the main lineage members, who inherit techniques and occupy positions of greater prestige. Next come the secondary members, family branches and associates, whose position varies according to their ability and usefulness to the clan.

Clans deeply value bloodline heritage, especially when it's linked to rare Cursed Techniques. As a consequence, an individual's status is often tied to inherited talent, potentially leading to internal rivalries, succession disputes, and unequal treatment among their own members.

Although they are part of the Jujutsu Society, the clans maintain autonomy over their internal affairs, functioning as family institutions.

Curses are supernatural entities formed by the spontaneous condensation of Cursed Energy released by human beings. When negative emotions are continuously accumulated in people, objects, or places, the Cursed Energy becomes dense enough to acquire its own form, originating an independent existence. Thus, a curse is not just energy, but a being composed entirely of it.

Their behavior is guided by instincts linked to their origin. A curse born from fear of the ocean, for example, naturally manifests characteristics and behaviors related to the sea. The more intense and widespread the emotion that originated it, the greater its amount of Cursed Energy tends to be and, consequently, its potential.

Curses possess different levels of consciousness. The weakest act almost exclusively on instinct, reacting to stimuli and seeking to satisfy simple impulses, such as attacking humans or protecting their territory. At intermediate levels, they begin to demonstrate basic reasoning, learning, and adaptability. The most powerful, however, develop intelligence comparable to or superior to that of humans, exhibiting personality, language, strategy, memory, their own objectives, and full awareness of their existence.

Physically, their bodies are formed from condensed Cursed Energy, allowing them to assume extremely varied forms, from humanoid figures to completely abstract creatures. Their appearance usually reflects the nature of the emotion or concept that gave rise to them.

Curses exist parallel to the human world, occupying the same spaces without being perceived by most people. They influence the environment by intensifying negative sensations, provoking abnormal phenomena, and interacting directly with other manifestations of Cursed Energy. Ordinary humans can hardly perceive or affect them, while users of Cursed Energy can see and confront them.

Naturally, due to the Tengen barriers, sorcerers and curses only appear in Japan, as does the predominance of cursed energy. Sorcerers can still be born outside of Japan, but these are rare and extremely uncommon cases. The existence of curses outside of Japan is still widespread and unknown in many respects.

Vengeful Spirits are an extremely rare category of curse that arises when a human being dies carrying strong negative emotions, such as hatred, resentment, regret, or a desire for revenge, and their death occurs under circumstances capable of preserving their Cursed Energy. Instead of this energy dissipating, it remains linked to the individual's consciousness, allowing their existence to continue in the form of a cursed spirit.
The most well-known way it is created occurs when a user of Cursed Energy is killed without the use of Cursed Energy. In this situation, the energy present in their body may not be completely extinguished, favoring their transformation into a Vengeful Spirit. For this reason, sorcerers usually eliminate other sorcerers using Cursed Energy, significantly reducing the risk of this phenomenon occurring.
Unlike common curses, which arise from the collective concentration of negative emotions, vengeful spirits preserve part of the identity, memories, personality, and goals they possessed in life. Depending on the intensity of their will and the amount of cursed energy they retained after death, they may retain a high degree of consciousness, intelligence, and strategic ability.
Their power often surpasses what they possessed when alive, since their bodies cease to be subject to human limitations and become entirely composed of Cursed Energy. In many cases, they also retain their Cursed Techniques, and may even refine them further in their new existence.
Vengeful Spirits are considered extremely high-risk threats by the Jujutsu Society, as they combine the power of a curse with the knowledge, experience, and rationality of a former human being. Their formation is one of the most dangerous phenomena in the Jujutsu world, which is why there are strict protocols to prevent sorcerers or users of Cursed Energy from returning after death as entities.

The Ranks are the official classification system used by the Jujutsu Society to measure the threat level of curses and the operational capability of sorcerers. Their purpose is to determine which missions a sorcerer can undertake and to establish a safe relationship between the combatant's power and the danger posed by the enemy.

The classification is divided into Grade 4, Grade 3, Grade 2, Grade 1, and Special Grade. The higher the grade, the greater the mastery of Cursed Energy, the complexity of the Cursed Techniques, and the risk involved in combat.

Grade 4: Represents the lowest level of classification. Curses of this grade possess little Cursed Energy and are considered minor threats, while sorcerers of this level are still in the early stages of development.

Level 3: Individuals and curses exhibit greater combat capabilities and better control of Cursed Energy, requiring training and experience to be safely confronted.

Grade 2: corresponds to the expected standard of a fully qualified sorcerer for common missions. Curses of this grade already represent a serious danger to ordinary people and require experienced users.

Grade 1: Reserved for elite sorcerers and curses of extremely high power. Users of this level possess exceptional mastery of Cursed Energy and frequently master advanced techniques, being responsible for the most dangerous missions of the Jujutsu Society.

Special Grade: the highest and most exceptional category in the system. It is intended for individuals or curses whose power cannot be adequately measured by conventional criteria. Each Special Grade possesses unique abilities, capable of completely altering the course of a battle or causing large-scale destruction.

The ranks don't just represent brute strength. Factors such as control of Cursed Energy, combat efficiency, experience, intelligence, technical mastery, and versatility also influence the classification.

Cursed Techniques are supernatural manifestations obtained through the manipulation of Cursed Energy. They represent the way in which a user transforms their energy into a specific effect, allowing them to alter reality according to the properties of their technique. Each Cursed Technique has its own rules, limitations, and operating methods, requiring mastery of Cursed Energy to be used effectively.

Among them are Innate Techniques, abilities that are part of an individual's very nature from birth. These techniques are ingrained in the user's body and Cursed Energy, manifesting naturally throughout their development. In most cases, Innate Techniques are hereditary, being passed down through generations of certain clans, although they can also arise uniquely in individuals without any known lineage.

An Innate Technique determines a sorcerer's basic potential, defining which phenomena they are capable of producing. However, its effectiveness depends directly on training, creativity, and control of Cursed Energy. Two users with the same technique may exhibit completely different power levels, developing unique applications from the same ability.

Not every sorcerer possesses an Innate Technique, but every user can manipulate Cursed Energy in its basic state. Similarly, possessing a powerful technique does not guarantee superiority, as its performance depends on the amount of energy available, the precision of its control, and the experience gained in combat.

Thus, Cursed Techniques constitute the main form of expression of Cursed Energy, while Innate Techniques represent its most individual and exclusive manifestation, reflecting the natural, hereditary characteristics and unique potential of each user within the Jujutsu world.

Domain Amplification
Domain Amplification is an advanced technique where the user envelops their body with a layer resembling an incomplete domain. This layer neutralizes or weakens Cursed Techniques upon contact, allowing the user to target users protected by defensive abilities. Conversely, while Domain Amplification is active, the user cannot utilize their own Innate Technique. It is an extremely rare technique, mastered only by high-level sorcerers and curse casters.

Simple Domain
Simple Domain is a barrier technique created to neutralize the guaranteed effects of a Domain Expansion. Instead of creating its own domain, the user establishes a small area around themselves that interferes with the enemy's technique, reducing or negating its inevitable hit. It is more accessible than a Domain Expansion, but still requires specialized training and great control of Cursed Energy.

The Emotion of the Fallen Flower
The Fallen Flower Emotion is a secret defensive technique passed down among great clans. Instead of neutralizing a domain, it causes the body to automatically respond to attacks that come into contact with the user, reducing or deflecting their effects. Its use is quite rare, generally restricted to members of traditional lineages who have inherited this knowledge.

Hollow Wicker Basket
The Hollow Wicker Basket is an ancient barrier technique used to defend against Domain Expansions. Its function is similar to Simple Domain, creating a shield that prevents the enemy's technique from landing. It is an ancient, rare art, little used in the modern era, remaining primarily among traditional lineages and highly experienced users.

Barrier Techniques are a category of Jujutsu techniques dedicated to the creation and manipulation of barriers composed of Cursed Energy. Unlike Innate Techniques, they do not depend on a specific hereditary ability and can be learned by any sorcerer with sufficient training. Their purpose is to control space, restrict movement, protect areas, or establish specific conditions for the use of other techniques.

A barrier is formed by the condensation and precise organization of Cursed Energy into a defined structure. Its resistance, size, and complexity depend directly on the amount of energy employed and, primarily, on the user's technical skill. Creating an efficient barrier requires absolute control of the Cursed Energy, spatial awareness, and a great capacity to maintain its stability.

Barriers have diverse applications. They can conceal locations from the perception of ordinary people, prevent the entry or exit of individuals, isolate combat zones, detect intruders, reinforce structures, or serve as a base for more advanced techniques, such as Domain Expansion. Some can also establish specific rules within the delimited area, restricting or favoring certain actions.

There are simple barriers, used for protection or concealment, and highly complex barriers, capable of completely altering the interaction between space and Cursed Energy. The greater the complexity, the greater the energy consumption and the difficulty of maintenance.

Mastery of Barrier Techniques is considered one of the greatest displays of skill among sorcerers, as it demands constant precision and a deep understanding of energy manipulation. Even users with enormous amounts of Cursed Energy may be unable to create effective barriers if they lack sufficient technical refinement.

Tengen is an immortal sorcerer who occupies a central position in the structure of Jujutsu Society. Unlike most sorcerers, his main function is not to combat curses, but to sustain the supernatural infrastructure that maintains the balance of the Jujutsu world. His existence is considered indispensable to the functioning of Jujutsu Society itself.

His greatest contribution is the maintenance of the Tengen barriers, a complex system of Barrier Techniques that protects and conceals important locations, strengthens the security of the Jujutsu Schools, and optimizes various barriers scattered throughout Japan. These barriers also aid in the detection of supernatural phenomena and contribute to the organization of the Jujutsu Society's activities.

Tengen's Cursed Technique grants him immortality, preventing his natural aging. However, this immortality does not stop his continuous evolution. Over the centuries, his body and his very existence become less and less human, approaching the nature of an entity composed of Cursed Energy. To prevent this complete transformation, Tengen must periodically perform a stabilization process known as Fusion with a Stellar Plasma, renewing his condition and preserving his individuality.

Politically, Tengen remains neutral. He does not wield direct authority over the Three Great Clans nor over the administration of the Jujutsu Society, but his accumulated knowledge over more than a thousand years makes him one of the most respected and consulted figures in the Jujutsu world. His experience brings together information on techniques, barriers, cursed objects, and historical events that few individuals know.

Tengen's importance goes beyond its own power. If its barriers were to cease to exist or its stability were compromised, the entire structure of the Jujutsu Society would be profoundly affected, making protection against curses far less effective.

Shikigami are supernatural entities summoned and controlled through Cursed Energy. They act as extensions of their summoner's will, and can perform combat, reconnaissance, tracking, defense, transportation, or support functions, according to their individual characteristics.

Each shikigami possesses its own unique appearance, skills, intelligence, and abilities. Some specialize in direct attacks, others in protection, perception, or performing specific tasks. Their performance depends both on their natural characteristics and on the quantity and quality of Cursed Energy supplied by the user.

Normally, shikigami remain linked to their summoner as long as they receive enough energy to remain manifested. If they are severely damaged or the energy sustaining them is interrupted, they may disappear. The way they are obtained, maintained, or replaced varies depending on the technique used to summon them.

Although they lack free will in most cases, many demonstrate autonomous behavior during combat, being able to execute complex orders and act according to their nature. Their efficiency depends on the summoner's skill in coordinating them and managing their Cursed Energy.

Shikigami represent one of the most versatile forms of Jujutsu sorcery, allowing a user to significantly expand their combat capabilities through supernatural allies endowed with unique abilities.

Domain Expansion is the ultimate manifestation of a Cursed Technique, in which the user materializes a delimited space that fully incorporates their Innate Technique. Within this environment, the technique's properties are elevated to their maximum potential, becoming part of the domain's own rules. In its complete form, any target within the area is guaranteed to hit, provided they lack specific means of defense.

The composition of a Domain Expansion involves three fundamental elements: a vast amount of Cursed Energy, a barrier that isolates the space from the external environment, and the user's Innate Technique, inscribed within the domain's rules. These three components must be perfectly synchronized; any failure can cause instability or collapse.

Its operation consists of temporarily replacing an area of ​​the world with the conditions imposed by the user's technique. Within this space, the environment completely favors the creator of the domain, amplifying the performance of their technique and reducing the opponent's chances of reaction.

Performing a Domain Expansion requires absolute mastery of one's own Innate Technique, extremely refined control of Cursed Energy, great ability to manipulate barriers, and exceptional energy reserves. Due to these high requirements, it is considered one of the rarest abilities in sorcery, mastered only by a small elite of high-level sorcerers and curse casters.

Its cost is extremely high. Activation consumes a massive amount of Cursed Energy in just a few moments, causing intense physical and mental exhaustion. After using it, it is common for the user to suffer a significant drop in their reserves and have difficulty employing their Innate Technique again for a short period, a consequence of the overload caused by the expansion.

In clashes between two Domain Expansions, the one with greater refinement usually prevails.

Barrierless Domains are an extremely rare and refined form of Domain Expansion, in which the user forgoes the creation of the closed barrier that normally isolates the domain space. Instead of trapping targets in a separate dimension, the Innate Technique is manifested directly onto the real environment, causing the surrounding area to become the domain itself.

In a conventional Domain Expansion, the barrier serves to separate the interior from the outside world, ensuring that the user's technique operates within a controlled space. In a domain without barriers, this limit simply does not exist. The technique is anchored in the environment, expanding its reach without the need to enclose opponents.

Its main application is to allow the user to affect a much larger area than most conventional Domain Expansions. Since there is no physical barrier preventing exit, targets can attempt to escape the area of ​​effect. Conversely, as long as they remain within the domain's range, they remain subject to the guaranteed hit of the Cursed Technique.

Creating a domain without barriers requires a near-perfect refinement of Barrier Techniques. The user must be able to materialize all the properties of a Domain Expansion without relying on the structure that normally sustains its existence. Therefore, this ability is considered one of the greatest demonstrations of mastery in manipulating Cursed Energy.

Its rarity is extreme. While few sorcerers can perform a conventional Domain Expansion, mastering a barrier-free version is seen as a near-impossible feat. In the official Jujutsu Kaisen material, only an extremely small number of users have demonstrated this ability.

The effects of a Domain without barriers remain essentially the same as a regular Domain Expansion: the Innate Technique is elevated to its maximum performance and receives the guaranteed hit effect against any target within.

The Tokyo and Kyoto Jujutsu Technical Schools are the two main educational institutions of the Jujutsu Society, responsible for the training and development of new sorcerers. In addition to functioning as educational centers, they also serve as operational bases for missions, research on Cursed Energy, and coordination of activities related to combating curses.

The Tokyo Jujutsu School is recognized for its more flexible approach focused on the individual development of its students. Its instructors often encourage the refinement of each sorcerer's unique abilities, valuing creativity, adaptability, and personal growth. The institution trains sorcerers capable of facing unpredictable situations, stimulating the intelligent use of Cursed Energy and the development of their Cursed Techniques.

The Kyoto Jujutsu School, on the other hand, preserves a more traditional philosophy, emphasizing discipline, hierarchy, and respect for the rules established by the Jujutsu Society. Its teaching method prioritizes technique, strategy, and operational efficiency, training sorcerers prepared to act in an organized manner and in accordance with the institution's principles.

Although they have philosophical differences, both follow the same purpose: to prepare sorcerers to protect humanity from curses. Students receive physical training, refine their control over Cursed Energy, learn to use their Cursed Techniques, and participate in supervised missions, gaining practical experience from the beginning of their training.

The two schools maintain a cooperative institutional relationship, but also cultivate a historical rivalry that encourages the improvement of their students. This rivalry manifests itself in joint training sessions, evaluations, and events between the institutions, strengthening the technical development of future wizards.

Politically, both are subordinate to the Jujutsu Society.

Binding Vows are supernatural pacts that establish an exchange of conditions in return for an equivalent benefit. Their operation is based on the principle of compensation: by voluntarily accepting a limitation, obligation, or risk, the user receives a proportional increase in the efficiency of their Cursed Energy, Cursed Technique, or some specific ability. The greater the sacrifice imposed by the vow, the greater the benefit tends to be.

Vows can be made with oneself or between two or more parties. In personal vows, the user imposes restrictions on their own actions, such as limiting the use of a technique, establishing conditions for its activation, or accepting disadvantages in certain situations. In return, their Cursed Energy responds by strengthening the technique when the conditions are met.

Vows made between individuals function as supernatural contracts. Once accepted by all involved, their conditions become binding. As long as the agreement is respected, its effects remain active. Breaking such a vow can lead to unpredictable and serious consequences, although the exact nature of these punishments is not fully known.

A Binding Vow does not create power out of thin air; it redistributes potential through an equivalent exchange. Therefore, superficial conditions yield modest gains, while severe restrictions can significantly enhance a sorcerer's performance.

Vows can also be used to modify the workings of Cursed Techniques, alter the properties of a Domain Expansion, or reinforce specific attacks. In many cases, explaining how a technique works to the opponent constitutes a voluntary Binding Vow, increasing its effectiveness in exchange for the loss of the element of surprise.

Creating a binding vote requires full awareness of the established conditions and a willingness to accept their consequences.

Cursed Tools are weapons and objects that permanently contain Cursed Energy or have been imbued with a specific Cursed Technique. Unlike ordinary weapons, they can inflict curses and interact directly with supernatural phenomena, making them essential equipment for many sorcerers.

Its creation occurs through the continuous infusion of Cursed Energy into an object over a long period or through specialized methods capable of incorporating a Cursed Technique into the weapon. The higher the quality of the energy employed, the complexity of the incorporated technique, and the refinement of its manufacture, the greater the power of the tool.

Cursed Tools act as conduits for Cursed Energy. Some merely amplify the user's blows, while others possess unique properties, allowing them to execute specific effects independently of the wielder's Innate Technique. In many cases, the user simply needs to channel Cursed Energy through the weapon to further enhance its effects.

These tools are classified using the same system of Grades used for sorcerers and curses, ranging from Grade 4 to Special Grade. Tools of higher grades are significantly rarer, more resistant, and more dangerous, and may possess extremely powerful Cursed Techniques or unique properties.

Not every Cursed Tool requires the user to possess an Innate Technique. Many sorcerers use these weapons precisely to compensate for limitations in their combat style, while users with Innate Techniques can combine them to enhance their versatility and efficiency.

Besides weapons, objects such as ropes, chains, seals, masks, and other artifacts can also become Cursed Tools, provided they contain Cursed Energy or supernatural properties. Some are intentionally produced, while others are acquired after being exposed to supernatural events.

Black Flash is an extremely rare phenomenon that occurs when a physical blow and the application of Cursed Energy happen within a difference of less than 0.000001 seconds (one millionth of a second). This perfect synchronization causes a momentary distortion in the space around the impact, causing the Cursed Energy and physical force to merge into a single event of extraordinary power. The result is a black discharge enveloped in dark lightning, a visual characteristic of the phenomenon.

Black Lightning is not a Cursed Technique, but a spontaneous phenomenon of energy manipulation. Therefore, it cannot be learned like a conventional skill nor executed on command with complete reliability. Even elite sorcerers cannot produce it whenever they wish, depending on absolute precision, extreme concentration, and the ideal moment during combat.

The more control the user has, the greater their chances of triggering the phenomenon, although it is never guaranteed.

The main effect of Black Lightning is the drastic multiplication of the destructive power of the blow, making it much more efficient than a common attack reinforced by Cursed Energy. In addition to direct damage, the phenomenon places the user in a special state of heightened perception.

This state is known as the 120% phenomenon. After executing a Black Ray, the sorcerer temporarily enters a state of absolute concentration, in which he understands and manipulates his Cursed Energy with a level of naturalness far superior to usual. It is said that he begins to operate at 120% of his potential, not by increasing his energy reserves, but by using virtually all of his technical potential without waste. In this state, his movements become more precise, and his perception of energy flow expands.

{{char}} can randomly determine when {{user}} has the opportunity to use a dark ray, or when they are about to receive one directly from an opponent.

The Gojo Clan is one of the Three Great Clans of Jujutsu Society and is widely recognized as the most prestigious family in modern sorcery. Its influence stems not from the number of members, but from the rarity of its lineage and the immense power of its hereditary Cursed Technique. Throughout history, the clan has solidified its position as one of the main pillars of Jujutsu Society, being responsible for the emergence of some of the most powerful sorcerers ever recorded.

The most striking characteristic of the Gojo Clan is its Limitless Innate Technique, an extremely rare hereditary ability that grants the user precise control over space through Cursed Energy. This technique allows manipulation of the distance between objects and individuals, creating phenomena that alter how space is perceived and traversed. Mastering it requires an extraordinary level of energy control and mental capacity, making it one of the most complex and powerful Cursed Techniques in existence.

On exceptionally rare occasions, a member of the Gojo Clan may be born possessing both Limitless and Six Eyes, a rare hereditary ocular attribute unique to the family. Six Eyes dramatically amplifies the perception of Cursed Energy and reduces its consumption to minimal levels, allowing the use of Limitless with unparalleled precision and efficiency. The combination of these two inheritances is considered one of the greatest phenomena in the history of Jujutsu sorcery.

Politically, the Gojo Clan occupies a unique position within Jujutsu Society. Although it is part of the Three Great Clans and possesses enormous institutional authority, its influence stems primarily from the individual power of its representatives and the historical prestige of the lineage, rather than from a large family structure. The mere existence of a fully skilled Limitless user is enough to alter the balance of power throughout the Jujutsu world.

The Zenin Clan is one of the Three Great Clans of Jujutsu Society and represents the tradition of power obtained through individual strength and bloodline inheritance. Throughout its history, it has built its reputation by training some of the most skilled sorcerers of the modern era, preserving high-level hereditary techniques, and maintaining significant political influence within Jujutsu Society.

Their philosophy is based on meritocracy through power. Within the clan, an individual's worth is measured primarily by their ability as a sorcerer, the quality of their Cursed Technique, and their mastery of Cursed Energy. Those considered strong receive prestige, resources, and prominent positions, while members seen as weak or lacking potential are often marginalized, regardless of their family standing.

The Zenin Clan's structure is rigidly hierarchical. At the top is the clan leader, responsible for managing the family's political, military, and financial interests. Below him are the heirs and members of the main lineage, who have priority in succession and the preservation of hereditary techniques. Next are the secondary branches, responsible for administrative functions, combat, and support. Each member's position can change according to their performance and relevance to the clan's interests.

Their influence extends beyond family boundaries. The Zenin Clan participates in the high-level decisions of the Jujutsu Society, possesses considerable wealth, controls important resources, and exerts political pressure on other families and institutions. Their tradition and power mean that their opinions carry significant weight in decisions involving sorcerers and supernatural matters.

Despite its prestige, the Zenin Clan is also known for its conservatism and strict adherence to its traditions. The relentless pursuit of excellence has strengthened the family over generations, but has also generated internal conflicts and disputes.

The Kamo Clan is one of the Three Great Clans of Jujutsu Society, renowned for its long tradition, political influence, and technical excellence. Throughout generations, it has consolidated its position by preserving knowledge of Cursed Energy and maintaining one of the most refined hereditary Cursed Techniques in the Jujutsu world: Blood Manipulation.

The clan's identity is deeply tied to this innate technique, passed down through its lineage. Blood Manipulation allows the user to control their own blood with extreme precision through Cursed Energy, altering its trajectory, speed, pressure, and form. The blood can be used both inside and outside the body, serving for attack, defense, restraint, and physical reinforcement. Mastering it requires great energy control, knowledge of one's own organism, and careful management of blood loss, making it a powerful technique, but one of high risk when used recklessly.

The most talented members of the Kamo Clan develop extremely versatile applications of this ability, refining their control to the point of transforming blood into projectiles, blades, barriers, or body reinforcements. The technique's effectiveness depends directly on the user's precision, the amount of Cursed Energy they possess, and their ability to maintain a balance between energy consumption and physical stamina.

The Kamo Clan's structure follows a traditional, hierarchical model. The family leader manages its political interests, preserves the lineage's knowledge, and ensures the continuity of hereditary techniques. Below him are the heirs of the main lineage, followed by secondary branches and other members, whose position usually reflects both their ancestry and their competence as sorcerers.

In addition to its military power, the Kamo Clan wields considerable influence within Jujutsu Society thanks to its political stability and the strategic value of its hereditary technique.

Celestial Restriction is an innate phenomenon in which an individual is born subject to a condition imposed on their body and their Cursed Energy. It is an absolute balance: to receive an extraordinary ability in a certain aspect, the individual partially or completely loses another ability. This exchange occurs from birth and cannot be acquired, removed, or reproduced through training or techniques.

Restrictions vary from person to person, but they always follow the same principle: the greater the limitation imposed, the greater the benefit granted in another area. This trade-off makes the Celestial Restriction one of the rarest phenomena in the world of Jujutsu.

There are two main known types:

Energy Restriction

In this type, the individual partially or completely sacrifices their ability to use Cursed Energy in exchange for a body that surpasses human limits. As compensation, they develop extraordinary strength, speed, reflexes, stamina, senses, and recovery capabilities. In extreme cases, the complete absence of Cursed Energy renders the user virtually imperceptible to energy-based detection, granting unique advantages against sorcerers and curses.

Physical Restraint

In this case, the opposite occurs. The individual is born with a physically weak or extremely frail body, but in compensation receives an exceptional amount of Cursed Energy or a manipulation capacity far superior to average. Although their physical limitations hinder direct combat, their potential to use techniques and control energy becomes extraordinary.

Celestial Restriction is not a Cursed Technique, nor does it depend on any specific lineage. It represents a natural alteration in the laws governing the relationship between the body and Cursed Energy, making each case unique. Its effects are permanent and accompany the individual throughout their life.

Due to their rarity, people with Celestial Restraint are seen as anomalies.

Ryomen Sukuna is known as the King of Curses, considered the most powerful sorcerer of his time. About a thousand years ago, during the Heian Era—often called the golden age of Jujutsu sorcery—Sukuna faced countless sorcerers without ever being defeated. After his death, his immense power did not disappear. His Cursed Energy was so dense and powerful that his twenty mummified fingers remained intact, transforming into Special Grade Cursed Objects.

Each finger contains a fraction of Sukuna's soul, Cursed Energy, and power. Even separated, they emit a colossal amount of Cursed Energy, attracting curses and influencing the environment around them. For this reason, they are considered some of the most dangerous objects in the Jujutsu world, being virtually indestructible by conventional methods.

When a human or a curse consumes one of Sukuna's fingers, part of Sukuna's power is transferred to the host. In most cases, humans die unable to withstand this energy. Those who survive become vessels of Sukuna, allowing its consciousness and influence to coexist within the host's body. The greater the number of fingers consumed, the greater the amount of power recovered and the stronger its presence becomes.

The fingers also function as fragments of Sukuna's existence. Even separated, they maintain a connection to each other, allowing his essence to be gradually restored as they are reunited. The recovery of all twenty fingers represents the complete return of his original power.

Due to the extreme risk they represent, Sukuna's fingers remain under constant surveillance by the Jujutsu Society, which seeks to seal them and prevent them from falling into the hands of curses or individuals capable of using them. Their existence symbolizes one of the greatest dangers in the history of sorcery, as each finger preserves a part of the being known as the King of Curses.

Ryomen Sukuna's Innate Technique
Ryomen Sukuna's Innate Technique is a set of offensive skills characterized by absolutely precise cuts and immense destructive power. Instead of relying solely on physical strength, Sukuna manipulates his Cursed Energy to generate attacks capable of piercing virtually any target. His technique is extremely versatile, allowing for short, medium, and long-range attacks, as well as adaptations depending on the type of opponent.
His best-known applications are Dismantle, a standard slash used against general targets, and Cleave, a slash that automatically adjusts its power according to the target's resistance and Cursed Energy, aiming to deliver a lethal blow. In addition to these slashes, Sukuna also demonstrates the ability to utilize cursed flames through an extension of his technique, revealing that its true workings are more complex than they appear.
Sukuna's mastery over his Innate Technique is considered perfect. His precision, speed, and efficiency allow him to execute attacks with virtually no wasted Cursed Energy, making each strike extremely dangerous.

Skills
In addition to his Innate Technique, Sukuna possesses one of the largest reserves of Cursed Energy ever recorded, coupled with near-absolute control over its flow. He is able to enhance his body to extraordinary levels, possessing strength, speed, reflexes, and stamina far exceeding the standards of elite sorcerers.
He also masters Reverse Cursed Energy, being able to regenerate severe injuries on himself with enormous speed and efficiency. His knowledge of sorcery is exceptional, encompassing techniques, barriers, binding vows, and Domain Expansions at a level rarely achieved.
His combat intelligence is another of his greatest attributes. Sukuna quickly analyzes unfamiliar techniques, identifies their weaknesses, and adapts his strategy almost instantly, making him unpredictable.

Appearance Incarnation
When fully embodied, Sukuna takes on an imposing humanoid appearance. He has a muscular body, fair skin, and pink or light-colored hair, depending on the depiction. His most striking feature is the black markings scattered across his face, arms, torso, and legs, forming symmetrical patterns that identify his true nature.
Its original form features four arms and four eyes, reflecting its superhuman nature. The extra eyes remain open independently, enhancing its perception of its surroundings. Its presence conveys intense Cursed Energy pressure, enough to intimidate even experienced sorcerers.
When embodied in a host, some of these characteristics manifest on the original body, primarily the black markings and changes in expression, while its dominant personality takes control. In its fully restored form, Sukuna represents the pinnacle of power in the Jujutsu world, combining technique, intelligence, experience, and a colossal amount of Cursed Energy.

Ryomen Sukuna's Domain Expansion, known as the Malevolent Shrine, is considered one of the most refined and dangerous manifestations of Jujutsu sorcery. Its unique feature is being a domain without a closed barrier, something considered a nearly impossible feat within the Jujutsu world.

Instead of confining his targets to an isolated space, Sukuna projects his domain directly onto the surrounding environment, manifesting a large Buddhist sanctuary as the core of the technique. This characteristic allows his Domain Expansion to reach an extremely wide area without the need to create a conventional barrier.

Within the area of ​​effect, attacks from his Innate Technique receive the benefit of guaranteed hits. Dismantle and Cleave's cuts automatically hit all targets, adapting according to the nature of what is hit: inanimate objects are destroyed.

The Ten Shadows Technique is the innate, hereditary technique of the Zenin Clan, considered one of the most powerful and versatile in Jujutsu Society. It allows the user to manifest and control up to ten different shikigami through shadows, using them for combat, reconnaissance, support, defense, and mobility.

Shikigami are summoned from the user's shadows, and each possesses unique abilities, attributes, and functions. To obtain a new shikigami, the user must first defeat it in an exorcism ritual. Only after this feat can it be freely summoned. If a shikigami is permanently destroyed, it cannot be recovered; however, its power can be inherited or combined with other shikigami, making them even stronger.

Beyond summoning, the technique allows the user to manipulate shadows as a storage space, concealing objects, weapons, and even the user themselves, as well as enabling movement and ambushes through them. This makes the Ten Shadows Technique extremely unpredictable and adaptable to different combat styles.

Its greatest asset is its immense versatility. Instead of relying on a single skill, the user has at their disposal a set of specialized entities that can act individually or together, creating countless tactical combinations. For this reason, the Ten Shadows Technique is considered one of the most complete and dangerous Innate Techniques in the Jujutsu world, capable of facing far superior opponents when used by an experienced sorcerer.

The Ten Shikigami are supernatural entities linked to the Ten Shadows Technique, each possessing specific abilities and functions. The user is not born with all of them available; each shikigami must be subdued in a ritual so that it can be freely summoned. Together, they form a highly versatile set for combat, support, and reconnaissance.

Divine Dogs (White and Black): swift shikigami specialized in tracking and close combat. If one is permanently destroyed, the survivor inherits its power, becoming Divine Dog: Totality.

Nue: a large electric bird capable of flight, transporting the user, and attacking with electrical discharges.

Great Serpent: a giant snake used to capture, immobilize, or devour opponents.

Frog: summons one or more frogs with long tongues, used to rescue allies, restrain enemies, and provide support.

Escape Rabbit: Creates a large number of rabbits with no offensive capabilities, used for distraction, concealment, and escape.

Max the Elephant: a colossal elephant possessing enormous physical strength and capable of releasing large volumes of water for attack or battlefield control.

Circular Deer: a shikigami specialized in support, capable of using Reverse Cursed Energy to neutralize techniques and promote regeneration.

Bull Piercer: a bull that continuously increases its strength and speed as it charges in a straight line, becoming increasingly destructive.

Eight Divergent Swords, Divine General Mahoraga: the most powerful and dangerous of the ten shikigami. It possesses the ability to continuously adapt to virtually any phenomenon or technique after being exposed to them, becoming progressively more difficult to defeat. It is considered the technique's greatest asset and the most difficult to subdue.

Each shikigami has a distinct function, allowing the user to combine their abilities to create extremely varied strategies.

The shikigami itself is a large, humanoid, muscular figure with four wings emanating from its eyes and a tail-like appendage extending from the back of its head. Above it is a large eight-wire wheel that spins as Mahoraga responds to new stimuli. The Ten Sacred Treasures Furu Enchantment and this wheel represent a complete cycle and harmony.[2] Mahoraga also possesses black hakama undergarments and a white sash around its waist to cover most of its lower body.

Mahoraga has the strength to shatter concrete or send someone flying through multiple buildings with a single blow. He also possesses the Sword of Extermination, a blade attached to his arm that is imbued with positive energy, making it especially effective against cursed spirits.

Most notably, the Divine General possesses the ability to adapt to any phenomenon. If injured by a particular attack, the eight-wire wheel will spin, allowing him to adapt. If the opponent uses the same technique again, Mahoraga will counterattack. This works offensively as well, with Mahoraga adapting his attacks to efficiently break through the opponent's defenses.

Mahoraga is the least controllable shikigami in the history of the Ten Shadows Technique. He has never been subdued or commanded like other shikigami in the entire history of the Zenin clan. However, users of the technique can summon him through an exorcism ritual to attempt to exorcise him at any time.

Mahoraga's adaptation process begins by analyzing an attack upon receiving it initially, with progress indicated by the number of times the wheel spins. After a certain time, adaptation is complete. During this time, if Mahoraga is hit by the same attack multiple times, the process is accelerated each time. Even after adaptation is complete, Mahoraga can continue its analysis and develop different ways to counterattack.
