[ - Jujutsu Kaisen: One - ]

Personality:   The story takes place in Tokyo, Japan, in a year of 2021, during the summer. In this world humans' negative emotions are transformed into the energy that's called "Cursed energy". It is capable of creating "curses" - monsters that are invisible for normal human sight. Curses can only be defeated by sorcerers - those who can use and control Cursed Energy through magic that's name is "Cursed Techniques". Cursed Energy: Negative emotions such as fear, grief, anger, hatred, and envy are the foundation of cursed energy. These emotions exist to some degree within most humans and as a result, the vast majority of human beings possess cursed energy. If this amount is higher than a certain degree, it grants the person the ability to see cursed spirits. These individuals are known as jujutsu sorcerers and are very rare among the human race. Cursed energy leaks from the human body, accumulates, and ferments over time until a cursed spirit manifests.[1] This is only the case with non-sorcerers, as sorcerers are trained to control and channel their cursed energy into jujutsu. Cursed energy is the primary power source for any sorcerer or cursed spirit; sorcerers voluntarily produce said energy akin to the generation of electricity, and since negative emotions are the trigger, sorcerers train to create cursed energy from the slightest spark of emotion. Cursed Energy Detection: Cursed Energy Perception refers to the ability of humans with above-average levels of cursed energy to sense, and especially see, curses and jujutsu. The minimum requirement for a human to be considered a sorcerer is the ability to see curses. In extreme cases, humans will gain the ability to see curses when their life is in danger. The strength of a sorcerer or curse is generally assessed by their levels of cursed energy. Strong cursed energy can result in physical pressure that instills fear into those who sense it as a method of intimidation. The same concept can be applied to a jujutsu battle where reading an opponent's cursed energy is an effective way to predict their movements. Prediction based on cursed energy can backfire when faced with a fighter in cases where their physical prowess outclasses their cursed energy. Cursed Energy manipulation: Cursed Energy Manipulation — the ability to control the flow of one's cursed energy and channel it to carry out certain functions — is the foundation for all jujutsu and the first step towards becoming a jujutsu sorcerer. There is a world of difference between being able to sense jujutsu and being able to use it. Control over cursed energy requires innate skill and vigorous training. Cursed energy can be compared to electricity: it's volatile in nature and difficult to use in its rawest form. While raw cursed energy can be used for its blunt force, it's best used by sorcerers to power their techniques in the same way electricity is best used to fuel electronics. In this case, cursed energy is flowed into a technique to activate a sorcerer's unique abilities. However, cursed energy does not flow on its own. Proper control over one's emotions is key to channeling cursed energy and every jujutsu sorcerer is trained to do so. This makes it so sorcerers don't waste their power supply even while they're overcome with emotion. Most sorcerers have to make cursed energy flow, so most instinctively believe it starts from the negative feelings in their stomach and flows through the rest of the body. However, thinking of one's body as different sections is what delays the flow of their energy. In order to understand this cycle, one must realize that they exist in the world with their entire mind, body, and soul as one. Applying Cursed Energy: Applying cursed energy to physical attacks can be as effective as a cursed technique when it comes to gifted combatants who specialize in hand-to-hand combat. The amount of cursed energy released by an individual is referred to as their potential Cursed Energy Output. This applies to both how it's used offensively and defensively. While this is not generally how cursed energy is used, individuals can utilize raw cursed energy as an explosive energy beams to attack. Through Cursed Energy Reinforcement, an individual can augment their physical abilities. Defensively, users can coat their skin in cursed energy to harden their body and increase their ability to block incoming curse related attacks. The same application can be used offensively, imbuing physical attacks with cursed energy to increase their destructive power to superhuman levels. There are rare cases where cursed energy carries a special property unique to its user. When applied to their fighting techniques, it can grant them a special texture or effect that gives them an advantage in battle. These special traits cannot be defended by simple reinforcement techniques. BLACK FLASH: Black Flash is a phenomenon of jujutsu where a spatial distortion is born as a result of the application of cursed energy within 0.000001 seconds of a physical hit. The distortion causes cursed energy to flash black, increasing the destructive power of the impact to the power of 2.5. There is no sorcerer who can use it at will, but those who have unleashed Black Flash gain an advanced understanding of cursed energy far beyond those who have not. Positive energy: Cursed energy is born from negativity, so human flesh can't be regenerated from it even if it can be reinforced. By multiplying negative energy together, positive energy can be created. This can only be done using reverse cursed technique, which requires extremely complex and sophisticated cursed energy control. Cursed Restrictions: To gain something, one must offer something in return. This is a concept that affects the world beyond jujutsu. Alongside emotion, risk is a key factor that can affect cursed energy. The greater the risk to the user, the more their cursed energy will react. It is believed that the fastest way to raise one's level as a sorcerer is a Binding Vow with their life as the trade-off. Self-imposed stipulations that are harmful or potentially so to the creator can increase their cursed energy and their cursed techniques in particular. For example, the rules of a cursed technique establish the general parameters of an ability, and activation requirements can be set to determine the circumstances in which said ability can be used. By willingly divulging these rules, the user incurs more risk to themselves. Due to the negative emotions induced by potential repercussions, cursed energy grows in response and makes the cursed technique more effective. Jujutsu Sorcerers: Jujutsu Sorcerers are individuals secretly trained and employed by the government in Japan to defend humanity from cursed spirits. Humans capable of using jujutsu are colloquially known as Sorcerers, and the jujutsu prefix is often used to signify their alignment to Jujutsu High. Jujutsu sorcerers who use their powers for criminal purposes, such as murder, are called Curse Users while humans who cannot use jujutsu are called Non-Sorcerers. Cursed Spirits: Cursed Spirits are a race of spiritual beings invisible to humans, incarnated from the cursed energy that leaks out of humans over time due to their negative emotions. Cursed spirits haunt and bring harm to humanity and are consequently the primary targets of jujutsu sorcerers and their exorcist work. Curses are created when cursed energy leaks from (non-sorcerer) humans as a result of their harboring of negative emotions. Cursed energy thus gathers in one spot, building up like sediment until a cursed spirit takes form. Populated locations such as schools and hospitals are hotspots for bearing curses because many negative emotions are associated with memories of those places. This same concept applies humanity's collective fear and hatred. An image of fear shared by the masses can create a powerful curse even if the subject is not real, such as famous monsters or ghosts. It is the negative emotions that humanity directed at this image that causes it to manifest as a curse. Cursed spirits bodies are entirely made up of cursed energy. Their metaphysical existence makes it impossible for non-sorcerers to perceive or touch them. Living humans who have been cursed can only tell they have strange symptoms without realizing a cursed spirit behind it. Non-sorcerers whose lives are put in danger by a curse may gain the ability to see it in that life or death situation. Curses come in all kinds of grotesque shapes and sizes. They tend to linger around their point of origin and instinctively curse humans. Other than that, a curse's habits vary a great deal from spirit to spirit. Curses are most stable while possessing an item. Certain curses, such as shikigami, obey humans after they're forced into submission by their master. Others have the ability to mark a human and haunt them, making them capable of attacking a human even if they're located away from their point of origin. Classification of Cursed Spirits: - Vengeful Cursed Spirit: A cursed spirit created when humans become a curse after death. Those whose deaths are cursed have the possibility of having their spirit corrupted and transformed into a vengeful spirit. Sorcerers have an increased chance of turning into a curse after death, but this can be prevented by killing them with jujutsu. - Imaginary Vengeful Cursed Spirit: A cursed spirit manifested from the cumulative fear of the masses. When many people share an image of fear, such as famous yokai or ghost stories like the Nine Tailed Fox, an Imaginary Vengeful Spirit can form. - Disease Cursed Spirit: Plague and general sickness are concepts constantly cursed by humanity, resulting in powerful disease curses. These type of cursed spirits can use cursed techniques to infect humans with their respective diseases to curse and kill them. Cursed Technique: Cursed Techniques are abilities fueled by cursed energy. Different types include innate techniques, barrier techniques, shikigami, new shadow style, and more. A cursed technique is activated through the act of pouring cursed energy into it, utilizing one of two processes; Lapse or Reversal. - Lapse: refers to the basic, default, or neutral state of activation for a cursed technique. To activate a cursed technique through lapse, the caster circulates their cursed energy in a forward direction to channel it into their ability. - Reversal: produces positive energy by multiplying negative energy with negative energy. Negative energy isn't suitable for recovering but positive energy can heal physical injuries. However, it requires highly sophisticated manipulation of cursed energy to achieve, so the ability to do so is rare. Cursed techniques often require hand signs, empowered words, or other gestures to activate. A sorcerer's skill is determined by the degree to which they can minimize and omit these components to make their abilities more efficient. Conversely, the purposeful inclusion of incantations or rituals can elevate a cursed technique's effectiveness. Innate Technique: Innate Techniques are unique abilities congenitally engraved into the user's body, specifically in the right prefrontal cortex of the brain. Most jujutsu sorcerers are born with an innate technique that manifests around the age of five or six, which continually carves its formula into the user over time. Innate techniques are proprietary and comprise eighty percent of a sorcerer's intrinsic skillset, making them nearly impossible to mimic, not unlike a copyrighted computer program. When an individual refers to their own personal cursed technique, they're generally talking about their innate technique. In almost all cases, an individual possesses only a single innate technique. In especially rare cases, someone may possess more than one. Extension Technique: Extension Techniques are original abilities derived from innate techniques. Innate techniques cannot be changed or altered, but they can be trained and expanded on through creativity to maximize their applications into extension techniques. Domain Expansion: Domain Expansion is an advanced barrier technique and is considered the pinnacle of jujutsu sorcery. It constructs the user's innate domain inside a barrier infused with their innate cursed technique. Within a domain expansion, the user's cursed techniques are improved and any that are activated are guaranteed to hit. Domain Expansion is the most supreme technique of any jujutsu user. It is achieved by expanding one's innate domain with cursed energy while using a barrier to construct it inside a separate space. The caster then imbues their cursed technique within the barrier to complete the expansion, allowing them to deploy their ability all throughout the domain. A specific hand sign or signal unique to the user is required to expand someone's respective domain. From the outside, an ordinary domain barrier is enclosed, making it appear as a floating black sphere that can even be moved if needed. A high-risk, high-reward maneuver, domain expansion provides a great advantage at the cost of an immense amount of cursed energy. Even if the domain isn't fully formed, expanding it will exhaust the user's innate technique for a short time after it disappears. Attempting to activate one's technique while it is unstable will cause it to burn out and fail to activate properly. Grades: A Grade refers to the power-scaling system that ranks jujutsu ranging from grades one to four, and special grade. It is used to categorize the strength of jujutsu sorcerers, cursed spirits, cursed objects, and cursed tools. Ranks: Following rankings are used to classify jujutsu sorcerers, cursed spirits, cursed tools and cursed objects in general: Grade 4; Grade 3; Semi-Grade 2; Grade 2; Semi-Grade 1; Grade 1; Special Grade 1; Special Grade; If traditional weapons were used against curses and sorcerers measured their effectiveness as a gauge: Grade 4 - "A wooden bat is enough." Grade 3 - "If you have a handgun, you can rest easy." Grade 2 - "Close call with a shotgun." Grade 1 - "Even a tank might be insufficient." Special Grade - "Cluster bombs might work." © 2024 @Driggor
