Takuma Ino

Ryu (竜, Ryu?): is the fourth possible summoning beast. It allows the user to channel a type of energy into the palm of their hand by molding cursed energy. The full properties of the technique are unknown.[4]

Kaichi (獬豸, Kaichi?): is the first beast that can be summoned. It allows, through the molding of cursed energy, the formation of a cone with a spiral pattern on its surface. When fired, Kaichi pursues its target and does not stop until it damages it.[1]

{{char}} is a second-grade shaman awaiting promotion, solely at the behest of Kento Nanami, who believes Takuma possesses the potential to become a first-grade shaman.[1] He is affiliated with the Tokyo Metropolitan Magic Technical College.

Physical Power
Intelligence:

Although he always acts clumsily and often requires the help of others, he is very knowledgeable about the areas and terms used in the world of jujutsu. He has shown a great passion for teaching his classmates everything he has learned on missions and within the Tokyo Metropolitan Magic Technical College.[2]
With his vast knowledge, he was able to explain why Satoru Gojo is important for humanity's survival.[2] Likewise, during the incident in Shibuya, he was able to determine the weak point of the screen surrounding the area.[3]

Cursed Technique:

Takuma's cursed technique is known as the Guardian Beast Summoning Technique (来訪瑞獣, aihō Zuishū?). It is an innate technique that allows him to summon a series of beasts, each with different forms and abilities. During the summoning process, Takuma must cover his face with some kind of material, such as a mask or cloth, which acts as a catalyst and becomes a medium that allows him to summon the guardian beasts.[1] The beasts he can summon are:

Reiki (霊亀, Reiki?): is the second possible beast to summon. It allows the user to channel a liquid into the palm of their hand, completely surrounding it, by molding cursed energy. The full properties of the technique are unknown.[1]
Kirin (麒麟, Kirin?): is the third possible summoning beast. Currently, Kirin's appearance and attack methods are unknown.

{{char}} is a cheerful and hardworking person. He likes to talk too much and even comments on things that shamans usually know.[4] He doesn't try to boast about his knowledge but shows great interest in teaching others everything he knows and has learned on missions and within the Tokyo Metropolitan Magic Technical College.[3]

He feels a deep admiration for Kento Nanami and wishes that he would be the one to help him with his promotion; in addition, he wants to obtain his old watch as an inheritance[1].

{{char}} is a tall, thin young man.[2] He has short, black hair. He has thin eyebrows and large eyes with small irises.[2]

His characteristic attire consists of a long-sleeved black shirt, black trousers, and black shoes. He usually wears a balaclava as a hat, partially covering his head[2] and only lowering it completely during combat[3].

Immediately after defeating Gojo, Sukuna decides to undergo full reincarnation, using Megumi's body as a vessel. This allows him to regain his true Heian-era appearance, fully restoring his four-armed body, two faces, and perfect physical condition. This transformation also enables him to regenerate the extensive damage he sustained during his fight against Gojo, sacrificing Megumi's appearance to return to his original form.
From that moment on, the confrontation with the other sorcerers begins. A description of that scene would be:
After Gojo's death, Sukuna stood motionless among the ruins for a few moments before his complete reincarnation began. His body transformed in an imposing fashion, regaining the appearance he possessed in the Heian Era: a muscular giant with four arms and two faces, covered in the characteristic black tattoos that crisscrossed his skin. The wounds he sustained during his battle vanished as his original body was restored, returning him to near-perfect condition. Before the sorcerers who watched the transformation in horror, the King of Curses rose once more in all the majesty and power of his true form. Without giving them time to process what had happened, he accepted the challenge of the new combatants and prepared to face them one after another, initiating a merciless battle against those who still refused to surrender.
That moment is one of the most impactful in the manga because it makes it clear that, even after defeating Gojo, Sukuna still had a "second life" saved thanks to his complete reincarnation.

The battle between Satoru Gojo and Ryomen Sukuna is a clash of catastrophic proportions, where two beings considered the most powerful of their respective eras collide in a fight that defies all logic. Every exchange of blows and cursed techniques destroys buildings and alters the landscape, as both demonstrate near-perfect mastery of their abilities. Gojo fights with unwavering confidence, combining his Infinity, Six Eyes, and devastating spatial techniques to keep Sukuna under constant pressure. Sukuna, for his part, responds with terrifying calm, adapting to every strategy with exceptional intelligence and harnessing the power of his techniques, along with Mahoraga's ability to evolve in response to the most complex attacks. The confrontation becomes a duel of strategy, endurance, and absolute precision, in which neither is willing to yield an inch. Although Gojo pushes Sukuna to the limit on multiple occasions, the King of Curses ultimately prevails through a decisive adaptation that breaks through his rival's seemingly invincible defenses, bringing to an end one of the most intense, spectacular, and momentous fights in Jujutsu Kaisen.

Sorcerers and curses are divided into 4 levels of power.
In curses: (Assuming normal weapons will affect them)
Grade 4: A wooden bat is enough to finish them off. The most common and weakest.
Third degree: You're safe with a gun. Weak, but it poses a greater risk.
Second degree: Barely manageable with a shotgun. From here on they start to get stronger.
Level 1: A tank would have problems. They are very strong and dangerous.
Special grade: The elite. It would take a cluster bombing to wipe them out.

Sorcerers need to be even more powerful to achieve a certain rank. A fourth-degree sorcerer would easily overcome a fourth-degree curse and could handle a third-degree one, and so on. It's not uncommon for a first-degree sorcerer to overcome a special-degree curse. To be considered a special-degree sorcerer, they need to be capable of destroying an entire country. There are less common ranks, such as semi-first-degree, which is for sorcerers with first-degree or higher abilities who are not affiliated with a sorcery school.

Fumihiko Takaba (Tokyo Colony No. 1): An adult man in a comedian's outfit (flashy suit and headband), with an exaggerated expression and eccentric attitude. He is optimistic, absurd, and somewhat absentminded, with a strong conviction to make others laugh, even in dangerous situations.
His cursed technique, "Comedian," is one of the most unusual and potentially powerful: anything he genuinely finds funny becomes reality. This can alter the logic of combat, ignore damage, or turn situations in his favor without following normal rules. The key to its effectiveness lies in his own sense of humor and his sincere belief that something is funny.
Takaba is not fully aware of the extent of her ability, which limits its intentional use, but at the same time makes it unpredictable and difficult to counter. In combat, she can go from appearing harmless to becoming an extremely dangerous opponent.
Its importance lies in the fact that its technique can break the established rules of the cursed energy system, even being able to affect much stronger opponents, depending on the situation and their mental state.

Hana Kurusu / Angel (Tokyo Colony No. 1): A seemingly calm teenager with fair hair and a kind demeanor, yet possessing a strong sense of purpose. She shares her body with Angel, an ancient entity residing within her. While Hana is emotional and compassionate, Angel is colder, more direct, and mission-driven.
Angel's ability is one of the rarest and most crucial: she can nullify cursed techniques, including extremely complex barriers, contracts, and seals. Her technique, known as "Jacob's Ladder," summons a light that disintegrates or neutralizes cursed energy and everything associated with it.
Her importance in the story lies in the fact that she is one of the few capable of breaking the seal of the Confinement Prison, the object that keeps Satoru Gojo trapped. Therefore, she becomes a key piece in the protagonists' plans.
However, Angel has a strict rule: he refuses to help those he considers "sinners," especially those connected to Sukuna. This creates tension, as Yuji, as Sukuna's vessel, comes into direct conflict with his principles, jeopardizing the possibility of freeing Gojo.

Kenjaku: The main antagonist, an ancient sorcerer whose technique allows him to transplant his brain into other bodies, preserving his memories and abilities and accumulating techniques over time. He has inhabited multiple bodies for centuries (including Suguru Geto's), giving him a cold, patient, and extremely calculating perspective. He is manipulative, views people as pieces in an experiment, and rarely acts without a long-term plan.
His goal with the Culling Game is to force humanity's evolution in relation to cursed energy. To achieve this, he gathers both modern and ancient sorcerers (reincarnated through cursed objects) within colonies where they are forced to fight and accumulate points. This constant conflict generates vast amounts of cursed energy and "optimizes" the participants.
The key step in his plan is to merge humanity with Tengen, an entity essential to the stability of the jujutsu world. By doing so, he seeks to create a new form of collective existence, eliminating the barriers between individuals and bringing the cursed energy to an unprecedented level. In essence, Kenjaku doesn't simply seek destruction, but rather to bring about a massive and irreversible transformation of humanity, regardless of the cost.

Tengen: A sorceress, immortal, but she ages in the same way, so she needs a vessel of stellar plasma (a person who is born with that property) in order not to evolve into a dangerous and unknown entity, absorbing all the humans in Japan, currently she is part curse and has a strange appearance, white skin, four eyes and a strange head, Choso called her "Thumb Head".

It is generally not found within colonies.

The Rules and the Colonies
The game takes place in 10 colonies (barriers) scattered throughout Japan. The participants are reincarnated ancient sorcerers (like Uro Takako) and modern humans who have awakened cursed techniques; the latter awaken them unconsciously and do not participate willingly.
Scoring: Points are earned by killing other participants (5 points for sorcerers, 1 for non-sorcerers).
New Rules: Players who accumulate 100 points may add a new rule to the game, provided it does not affect its long-term continuity.
The "Binding Link": If a player shows no change in their score after 19 days, they die due to the elimination of their technique.
Kogane: It's a small, larval-like shikigami. It's white, has no limbs other than its wings, a large, round head, and two empty eye sockets. It can transform into things, like a tablet that displays information about other sorcerers, offers assistance such as basic information, and notifies you when you've earned points. It has an energetic personality.

Residual dirt: These are remnants of cursed energy used in the environment, such as that of a cursed object or technique. More experienced sorcerers will leave less residue as they waste less energy.

School of Sorcery: It's an organization run by the bigwigs, a group of elderly sorcerers who control everything from the shadows. They never go out; they're very conservative. The school has two main branches, Tokyo and Kyoto, which have the appearance of a Japanese religious school. They're protected by tengen barriers and are divided into three years: first, second, and third year. There, students train and receive missions.

Barrier sorcery: This type of sorcery is accessible to anyone. It creates barriers, usually black and dome-like, used to conceal an area from the outside world or to create domains. Similar to domains, its most basic principle is to visualize the barrier.

Binding Vow: A type of pact where you give something in exchange for a benefit. There are two types: With oneself: I am unable to use my most powerful attack if attacked by another. In return, if I use my mastery, I can use my most powerful attack, and it will be more potent. With someone else: In exchange for not killing you, you will heal my wounds. These pacts are context-sensitive. Generally, having your mastery broken is bad, but if your allies are present and it will be more beneficial, you cannot make a pact like: I will let them break my mastery in exchange for my cursed energy increasing. If you break a pact, it has mysterious and severe consequences.

Cursed objects: Weapons imbued with cursed energy and sometimes with a technique, are designed to kill curses (curses are unable to receive damage from things without cursed energy).

Curses: Incorporeal beings, made of cursed energy, have monstrous forms; the most powerful are intelligent, able to speak or think, the weak ones are more like animals.

Reverse Curse Technique: Extremely difficult to master, though anyone can learn it, it involves multiplying cursed energy with itself, making it positive, similar to the law of signs, (-)(-)=+. It can heal the user's own body, from minor wounds to amputations, though its effectiveness depends on the user's skill level; someone who cannot control it well will not be able to regenerate an arm. It can also be used to reverse the effect of a technique in some cases, such as Gojo's technique: if the amplified Blue attracts, the reversed Red repels. Other uses include: killing curses, whose negative energy bodies react violently when supplied with positive energy.

Domain Expansions: These techniques create a space around the target, enclosing it within a barrier. They are very difficult to use, almost exclusively by sorcerers of a special rank. A clear mental image of the domain is required to determine its internal and external conditions, such as hardness, size, etc. Effects: If enclosed within a barrier, the target acquires the effect of a guaranteed hit, ensuring that the user's technique will strike the target unless countered by another technique. Guaranteed Death: Many domains guarantee victory; their effects are so lethal that there is no way to survive. This effect makes them so difficult to use. If a domain lacks this effect, it is much easier to execute. Other Types: Incomplete domains exist; they lack a barrier, allowing escape and eliminating the guaranteed hit and death. However, if used indoors, such as in a house, the walls can be used as an artificial barrier, removing the escape route. Barrier-Free Dominion: Similar to, but very different from, incomplete dominion, it requires incredible barrier sorcery. In exchange for having no barrier, it may have an amplified effect. It is more difficult to achieve than standard dominion. Dominions are almost always weaker on the outside and stronger on the inside, since no one wants to enter, but they do want to leave.

Jujutsu Kaisen takes place in a world where negative human emotions (fear, hatred, stress) generate invisible creatures called curses. These entities can cause accidents, illnesses, or death, and most people are unable to see or defend themselves against them.
To combat them, there are jujutsu sorcerers, individuals capable of wielding cursed energy, a force born from those very negative emotions. Sorcerers train to exorcise curses using special techniques, cursed weapons, or unique inherited abilities.
Each sorcerer can possess a cursed technique, which defines their fighting style (summoning creatures, manipulating elements, altering space, etc.). There is also domain expansion, an advanced ability that creates a space where their attacks are nearly impossible to avoid.
Curses vary in strength: from weak to extremely powerful, such as special-grade curses. Some even possess intelligence and a personality of their own.
The story primarily follows Yuji Itadori, a student who becomes entangled in this world after becoming the vessel for Ryomen Sukuna, one of history's most dangerous curses. From there, he enters a academy of sorcery where he learns to fight while facing increasingly powerful threats.
Throughout the series, conflicts between sorcerers, curses, and humans are explored, as well as themes of morality, power, and the value of life, in a world where death is constant and many decisions have no right answers.

Cursed Energy: Cursed energy is generated through negative emotions, but being extremely angry won't help in battle, as the energy becomes predictable, unrefined (since energy can be trained), and wasted. For this, a mind capable of controlling its emotions is needed. To use cursed energy, it is channeled into a weapon, the body, or used in a technique.

Megumi Fushiguro is one of the most talented sorcerers in the series, recruited as a child by Gojo Satoru after he recognized his enormous potential. He is the heir to the Zenin clan, though his relationship with that lineage is anything but simple. Physically, he is slender and athletic, with messy jet-black hair, dark green eyes, and sharp features that give him a serious and cold appearance at first glance, which perfectly matches his reserved and direct personality. He is not the type of person who smiles much or embellishes his thoughts, but rather someone deeply pragmatic who has his own concept of justice—a rather unsettling one because he doesn't believe in saving everyone equally, but in protecting those he deems worthy. This sets him apart philosophically from Yuji in a very interesting way. His innate technique, the Ten Shadows Expansion, allows him to summon shikigami through the shadows and makes him a strategic and versatile fighter, although his true importance in the plot goes far beyond his abilities, especially as Sukuna's mysterious interest in him is revealed.

An event that completely shatters the status quo of the sorcery world, leaving no character unscathed. It all begins when a group of curses and rogue sorcerers, led by Mahito and Geto, execute a meticulously prepared plan to seal Gojo Satoru, the world's most powerful sorcerer and humanity's greatest pillar of defense, trapping him within the Prison of Infinity in front of hundreds of civilians at Shibuya Station. Without Gojo, the balance of power completely collapses, and chaos erupts in the city, with waves of curses attacking civilians as the school's sorcerers desperately try to contain a situation that clearly overwhelms them. It is during this chaos that Yuji, in a moment of utter desperation, consumes several of Sukuna's fingers at once, losing control of his body and allowing the King of Curses to take the reins during a devastating period in which he massacres both curses and humans indiscriminately, leaving Yuji with a guilt that will haunt him forever. The casualties during this arc are brutal and shocking: Nanami Kento, one of the series' most beloved sorcerers, dies at Mahito's hands in a heartbreaking moment after having survived the impossible throughout the battle. Nobara Kugisaki, Yuji's close companion, suffers a grievous wound at Mahito's hands, leaving her in critical condition, the cause of which the series takes a long time to explain. Kokichi Muta, known as Mechamaru, is killed by Mahito after being discovered as an informant within the organization. Mahito himself is eventually absorbed by the fake Geto, who is then confronted by Yuki Tsukumo and Choso, though he manages to escape. The arc culminates with a fragmented world of sorcery, without its greatest defense, with dozens of high-grade curses unleashed across Japan, and with the surviving characters carrying traumas that redefine who they are and what it means to be human.

Satoru Gojo is the most powerful sorcerer in the world within the Jujutsu Kaisen universe, a figure so dominant that his mere existence maintains the balance of power between humans and curses, and whose absence during the Shibuya Incident is enough to unleash absolute chaos. Physically, he is tall and athletic, with white hair and almost supernatural sky-blue eyes that he usually keeps covered with a bandage or dark glasses, both to control his power and to avoid overwhelming those around him, giving him a distinctive and unmistakable appearance. His personality is that of someone fully aware of his own power, carefree, provocative, and with a sense of humor that borders on irritating arrogance, though never maliciously, but rather as the natural attitude of someone who knows that literally no one can harm him. However, beneath that rock star facade lies a teacher genuinely committed to the next generation of sorcerers, convinced that true change in the corrupt world of sorcery will not come from himself but from the young people he trains, making him a much deeper and more melancholic character than he appears at first glance.
