1. #1Judgement (Organization)constant

   Judgment (風紀委員ジャッジメント, Fūki I'in (Jajjimento)?, lit. "Public Morals Committee Member") is a term used to refer to Academy City's student-based disciplinary committee.[2] They are composed of students of varying grade levels and power, and along with Anti-Skill, they are tasked to maintain peace-and-order within the school system. Judgment members can be recognized by the armbands they wear over their right sleeves, which are green with white stripes and which have a shield symbol.

   As most of the city population are students, it is the duty of Judgment to catch those delinquents misusing their powers along with other offenders and protect the students. They can arrest criminals, though only Anti-Skills can formally take them into custody.[3][4]

   In the event of a situation that Judgment members cannot handle, their superiors and the city's security forces, the Anti-Skills will take over. Overall, the role of a Judgment officer is more like a part-time civilian patrol officer and are often used in community services, such as cleaning garbage from the streets (when cleaning robots are unavailable), helping locate lost objects, traffic duty, etc.

   Moreover, it is also their duty to keep watch of Anti-Skill, and vice-versa. It is a check-and-balance system that should prevent internal corruption in the two organizations.

   Joining Judgment's ranks requirement is only being an Academy City student, though it is unknown what the minimum age required is, as elementary students are allowed to join the ranks. Also, recruits need to pass 13 kinds of tryouts and training (which includes going to Judgment Training Center to train) lasting for 4 months, and sign 9 contracts, before formally becoming a member of Judgment. Academy City recruits Judgment twice a year, summer and winter.

   Younger members of Judgment are partnered with older members to patrol the city, though when one reaches a certain age, a member is allowed to patrol alone or form partners with other members of the same branch. During large-scale operations, several members of Judgment of the same branch can form a group for patrols.

   There are at least 177 currently known Judgment branches in Academy City, each branch has its own captain; Konori Mii is currently the head of Judgment 177 Branch Office.

   There is also a secret Branch 000 (第〇〇〇支部, Branch 000?), an elite execution squad which is mobilized on the confirmed death of a Judgment member (a situation referred to over radio by the unique code Number 000 (ナンバー000, Nanbā 000?)).

   Other than the unique abilities of each individual, members of Judgment are trained on how to apply first aid. They are also probably trained in basic emergency situation responses, as well as basic physical training.

2. #2Uiharu Kazariconstant

   Keys: Uiharu, Kazari

   Uiharu Kazari is a 1st year student attending Sakugawa Middle School in class 1-D along with her friend Saten Ruiko who often teases her by flipping her skirt (which she does to Uiharu only). She is also known for wearing a headband of flowers (and a surgical mask, as she constantly suffers from flu). She has a sweet tooth but is always called for Judgment duties before she can enjoy her sweets. She displays various advanced skills with computers, such as repelling hackers and gathering information.

   Uiharu uses polite Japanese almost exclusively, regardless of mood or standing; she addresses everyone by their family name accompanied with the honorific -san, even Saten and Haruue, and she always uses desu and the polite forms of verbs.

   Uiharu is usually shy and humble but always friendly. She is also shown to be equally high-spirited as her friend Saten Ruiko. She admits that she is composed most of the time because of a so-called "limit" she places on herself. Without that limit, she is very energetic and can be airheaded at times as well, as shown during Tokiwadai Dormitory's Festival. Moreover, she is intrigued and interested in the Ojou-sama lifestyle, as shown with her trying to impress Kuroko with her tea making abilities, as well the above mentioned excitability of her person during the Tokiwadai Midsummer Festival.[3] Although she is incapable of normal combat like Kuroko, she still has a strong sense of justice, being a member of Judgment, and will do her utmost to do her duty.

   Apparently, she is an animal lover, as she was the only one of her friends that wasn't scared of Ekatrina, Kongou Mitsuko's pet python, and even played with it.

   She joined Judgment when she was still in elementary school along with Shirai Kuroko. They were caught in a bank robbery attempt when their senpai, Konori Mii, had been injured and Uiharu was taken hostage. After being teleported out of harm's way and subduing the culprits (with the secret help of Misaka Mikoto) by Kuroko, she and Kuroko vowed to mature and become better members of Judgment.

   She later holds true to this, and joins Kuroko as a member of Judgment 177 Branch Office.

   Uiharu Kazari is a small girl who sports short black hair and has golden-brown eyes. She has thick eyebrows but her most striking feature is her headband made out of artificial flowers. In the manga she often wears a facemask because she is easily afflicted by colds and flu.

   She is a Level 1 Academy City student, and along with her colleague and friend Shirai Kuroko, is a member of the student composed law enforcement organization, Judgment.

3. #3Saten Ruikoconstant

   Keys: Saten, Ruiko

   Saten is superstitious despite being in the city of science, though she likes to presume otherwise as when she states that she doesn't believe that her mother's good luck charm actually works.[7] Because of this, she is a fan of internet rumors and urban legends, and loves telling her friends about them. This extends to herself, believing that her nose is sensitive to money, though she backs this up by showing Mikoto four bank cards she had already obtained.[8] She has a natural tendency to be nosy regarding this, and often gets herself into trouble because of it, often needing to be saved by coincidental events or having become involved in events.

   Saten can be described as a normal-acting preteen in the series in comparison to her peers, not having any extracurricular activities like Judgment or being particularly book smart. She is very affable, quick to make friends, and cheerful. She knows the latest trends and fashions, and in fact has the most wardrobe changes.

   Saten has an outgoing and friendly personality, but is a little shameless as she sometimes flips Uiharu's (and only her's) skirt in public. At first, she displayed apathy towards being a Level 0 but then became envious of the abilities of her friends as she was unable to fulfill her dreams as an esper. Due to this, she used the Level Upper. Later on, she grows to accept herself and becomes determined to develop her own abilities. Like her friend Uiharu, she also has a deep sense of friendship; she was instrumental in helping Uiharu and Kuroko make amends and made Mikoto realize that she has friends who she can count on. She is also adept at reading the atmosphere, and often changes the topic when someone is feeling uncomfortable about something.

   She was born outside Academy City and when she was younger, she decided that she wanted to go to Academy City to become an esper. She even boasted to her brother that she was going to get powers. Her mother, although disapproving of her decision as she was afraid of what the city would do to her head, supported her regardless and said she could come back anytime. Her mother also gave her a good luck charm, which is shown to be always attached to her bag.

   Sometime in Academy City, she became close friends with Uiharu Kazari. She eventually enrolled into Sakugawa Middle School along with Uiharu and was classified as a Level 0. She also let down her hair and wore a white flower on the left side of her head. She is currently a 1st year student in class 1-D.

   She is a Level 0 Academy City student and a classmate and close friend of Uiharu Kazari.

4. #4AIMconstant

   Keys: AIM, Esper, Personal reality, · Secondary: An Involuntary Movement

   "An Involuntary Movement", better known as AIM (無自覚AIM, Mujikaku (AIM)?, lit. "No Awareness"), is a term used to refer to the phenomena where an esper involuntarily emits an invisible energy field from their body, known as an AIM Diffusion Field (AIM拡散力場, AIM Kakusan Rikiba?, Yen Press: Involuntary Diffusion Field).[1]

   Closely connected to the Personal Reality that is the source of their ability, it is an esper's unconscious interference with reality. Differing between espers and usually having microscopic effects, it can only be detected through the use of machines or specialized espers.

   AIM is a weak energy that is unconsciously emitted by espers. Similar to how living beings radiate body heat, this energy emanates from the esper's body into their surroundings, forming what is known as an AIM diffusion field. These fields produce tiny effects on the regions they cover.

   The form taken by an AIM diffusion field and the effects it creates will differ based on the ability of the esper producing it. For example, pyrokinesists produce heat, telekinesists exert pressure, electromasters release electromagnetic fields, etc. The attraction of vampires by Deep Blood is also a likely example of this phenomena.

   When the AIM diffusion fields of espers with the same type of ability overlap, an AIM diffusion field resonance can occur, which augments the effects they have on the surrounding area.

   As the effects of the AIM diffusion fields are usually microscopic in scale,AIM cannot be detected by the five conventional senses. It can only be detected through the use of machines, precision measuring devices or by certain espers, either through resonance or specific abilities. However in some cases under normal circumstances, certain secondary effects resulting from the effects of the AIM diffusion fields on their surroundings can be observed. An example of this would be wind turbines turning due to the electromagnetic fields released by Misaka Mikoto.

   There are a number of espers who have abilities which allow them to sense and even manipulate AIM. One notable esper of this kind is Takitsubo Rikou, whose ability AIM Stalker allows her to detect and track the AIM of espers whose AIM diffusion fields she has memorized. She also has the potential to be able to use an esper's AIM diffusion field to manipulate their ability and Personal Reality.

   Due to their supernatural origin, the Imagine Breaker can nullify the parts of AIM diffusion fields it touches, and their effects with it. The effects of the Imagine Breaker on the AIM diffusion fields can be used as a way to monitor its power.

   Personal Realities are irreconcilably connected to AIM, as Personal Realities are the source of esper abilities and all phenomena manifested by espers in the real world. Since an AIM diffusion field is unique to the esper emitting it,[8] it can be assumed that this is due to the esper's Personal Reality.

   In cases of RSPK Syndrome, an esper becomes stressed or traumatized to the point of being unable to view reality properly and loses control over their Personal Reality, which then affects the esper's surroundings through their AIM diffusion field in a manner similar to that of a poltergeist (hence the alternative term used to refer to the condition). Additionally, interference to AIM diffusion fields can lead to a simultaneous outbreak of RSPK Syndrome.

   The connection between Personal Reality and AIM diffusion fields can be exploited in several ways. Analysis of a person's AIM diffusion field can be used to figure out the nature of their Personal Reality and in turn, investigate their personality and behavioral traits. It is also possible to influence a person's Personal Reality via interference to their AIM diffusion field, and at a certain level, it is apparently possible to modify a Personal Reality through it.

   Personal Reality (自分だけの現実パーソナルリアリティ, Jibun dake no Genjitsu (Pāsonaru Riariti)?, lit. "Reality of Oneself") is the term used to refer to the reality created by students who undergo the Power Curriculum Program, and replace normal reality. As the name states, it is a type of reality that is unique for each individual, and is the very foundation of an esper's power, specifically, it is the source from which all esper powers and phenomena are brought into the real world.

   The concept of Personal Reality is related to quantum theory. It enables its user to ignore the Uncertainty Principle, and with regards to the Schrödinger's cat thought experiment, will allow them to interfere with and distort the microscopic world using different laws. This is so the user can control their microscopic observations of the world and actualize the possibility of their choosing. This is in contrast with holism, which is based on major changes in the whole "system", the macroscopic world, to create a microscopic effect, which is in this case, their powers.

   The aquisition of a Personal Reality is described by Tsukuyomi Komoe as being "cut off from proper reality and achieving one that differs from ours". Uiharu Kazari and Saten Ruiko described it as delusions, preconceptions, or the ability to believe. Assuming this is so, one's esper powers will grow if they strongly believe they will.

5. #5Esperconstant

   An esper (能力者, Nōryokusha?, lit. "Ability User") is an individual who uses scientifically based supernatural powers and emits AIM. The term usually refers to those enrolled in the Academy City Power Curriculum Program, who gained their powers artificially, but can also refer to natural espers, also known as Gemstones. It is also used to refer to magicians by those unaware of the magical nature of their abilities, and therefore treat them as esper-related.

   In-universe, espers have only existed for a few decades up until this point.

   The term "esper" does not automatically imply ESP, one of the two classifications of powers in Academy City, as it could also refer to an ability user that does not have extrasensory perception but instead influences objects in their surroundings, referred to as Psychokinesis. Abilities such as Pyrokinesis are considered esper powers despite the user not having extrasensory perception.

   Academy City's espers have existed for over half a century in the world of Toaru, with the first modern esper being a girl nicknamed "the Beginning Child", who was trained by Academy City based on Meiji-era psychic Mifune Chizuko's data.[ The system used for the Beginning Child would become the foundation for the Power Curriculum Program to create espers.

   Espers are described by Index as individuals with "talent"; this likely refers to Gemstones and each cannot use magic without injuring themselves. An esper is created after passing through the Power Curriculum Program, thanks to which the esper now possesses a Personal Reality, their capacity to substitute reality with their own which is the basis of their abilities, with no two people have the exact same one. In contrast to Magic's Idol Theory, their interference with and subsequent distortion of reality to create effects is an isolated phenomenon based on quantum theory, their observations of the world based upon their Personal Reality affecting things on a micro quantum level to cause phenomena on a macro level. An opposite theory would be holism, where a large interference with the laws of the whole world is used to make effects on a smaller scale.[8] Aside from the mental performance of calculations, no elaborative and preparatory rituals are required by an esper to produce effects related to their abilities, unlike in Magic.

   Espers can only access one specific power;[9] Misaka Mikoto, for example, can only control electromagnetic phenomena. Despite this, however, researchers have attempted to create espers with multiple powers, such as Dual-Skill and Multi-Skill espers. Moreover, esper abilities are compartmentalized into two categories: Active and Passive. Active abilities require conscious effort to use, while passive abilities require subconscious effort. Abilities can be classed as both active and passive, such as Accelerator's ability. Esper abilities are further grouped into two major categories, Psychokinesis (PK) and Extrasensory Perception (ESP), with PK having a higher precedence in the classification of esper powers than ESP, especially when an esper power sits on both sides of the boundary between ESP and PK.

   Another aspect of espers is that every one of them, even Level 0s, subconsciously radiates an AIM Diffusion Field, minutes amount of their power in a way akin to body heat and weak enough that it can be felt by any of the human five senses and is only detectable through machines. Different powers means a different AIM Diffusion Field: a Pyrokinetic for example will emit AIM that will heat up their environment, a Telekinetic will emit pressure, and an Electromaster will emit a weak magnetic field. According to the Professor, AIM is not simply weak energy emanating from espers, but the unconscious interference against reality, and analyzing its composition and strength gives more insight into the Personal Reality of a given esper than a psychological profile.[14] There does seem to be some direct connection between the AIM Diffusion Field and Personal Reality, if Takitsubo Rikou being able to affect the latter through the former is any indication.[15]

   Esper powers are controlled using complex calculations done mentally,[16] so the strongest espers are also Academy City's greatest honor students.[17] Because esper abilities rely on mental calculations and concentration, if anything affects the esper mentally, be it pain, exhaustion, surprise, or confusion, they will not be able to perform the calculations needed and their powers won't work. The AIM Jammer takes advantage of this, essentially disturbing espers' concentration.

   While the brain is an important component to esper power, it is not the only factor. The entire physical human body is also part of this system and controls the power, though the exact mechanism is not well understood. Produce tested and researched to find out where exactly in the body esper power resides, removing limbs, organs, and brain parts from subjects, but the power still remained, although its output decreased as the body grew smaller, leading the researchers to conclude esper power can only reside in a body containing something that could be called a soul.[25] Likewise, it is shown that, as long as something is considered a part of the body by the esper, esper abilities can be used with it, no matter if that part is attached or detached, artificial or natural. Kuroyoru Umidori can use Bomber Lance through her detached cyborg arms, which she considers parts of her body; Kakine Teitoku can control his Dark Matter even if it's not directly touching his body by no longer distinguishing between his actual body and the parts fabricated from his power; and Rensa operates by changing her biological structure to that of other espers so she can use their abilities.[30] Coffins also operate on this principle, tricking the brains of dead espers into thinking bigger mechanical bodies are their own, which in return make the power stronger.[25]

   Genetics also have some influence on esper powers,[31] and DNA can be used to determine esper powers.[32] The very existence of the Parameter List and its ability to predict the future development of an esper before even passing through the Power Curriculum Program might be due to this fact, especially as they used it to get the DNA map of a future Level 5 for cloning ahead of time.[15] Another manifestation of this is how siblings tend to get the same or similar powers: the Tobio twins have the exact same power, the Yumiya sisters have the same power but at different Levels, and Acid and Counselor both have oxygen-related powers. And, while they are not true siblings, there are no clones, or Sisters, of Misaka Mikoto with non-electrical powers.[31] This is not an absolute rule: for example, the Gokusai sisters, or at least Kaibi and Amazora, have completely different powers. The triplets Ichika, Futaba, and Mitsumi likewise each have a different power. Yugure Kanaria and Yugure Tsumebakei also have different abilities. It may be that the possibility of similar and identical powers is weaker for ordinary siblings and fraternal twins than it is for identical twins and clones, who share the exact same genetic makeup.

   Academy City's curriculum begins at 5-years-old at the earliest, and hormones generated during puberty and adolescence are considered critical to esper development. This might explain the prevalence of espers of kid and teenage age. In fact, it seems that is impossible to become an esper if one is an adult,[36] to the point that the existence of adult espers is seen as improbable. So far no adult esper have been shown to exist,[40] aside from those who used various means to artificially get esper powers, like Kiyama Harumi with Level Upper,[9] Kihara Gensei with Exterior,[41] Houjou Seigo with Ideal,[42] and Kihara Byouri with her Equ.DarkMatter implants.[43]

   Ultimately, espers are considered only a byproduct of the Power Curriculum Program on the way to reach SYSTEM,[44] with the reasons and mechanisms behind their existence being the actual objective of the city's scientists.[45] Aleister compares espers to litmus papers changing colors in solutions of different acidities: the interest is in why they changed colors and if it can be manipulated, not the colors themselves.[46] Essentially, espers are a means to an end, not the end itself.

   A Gemstone esper is an individual who can emit AIM without requiring participation in any power development program. Gemstones are the beings that Index likely referred to as having "talent"; the envy of their abilities from their peers is what led to the creation of magic.[4] There are currently 50 confirmed Gemstones in the world.[53]

   In extension to this, it has been speculated that there may be people who have not realized that they have powers, or that their certain propensities or idiosyncrasies, as subtle as good looks or good penmanship, may actually have this power.[54]

   Many Academy City students are aware of Gemstone rumors, but treat them as urban legends. This is due to many feeling that it is unfair for esper powers to be gained without having gone through the Power Curriculum Program to attain them. Currently, Sogiita Gunha, who is the strongest Gemstone, and Himegami Aisa are the only two known Gemstone's in Academy City. Kamijou Touma, as mentioned by Kumokawa Seria, does not classify as a Gemstone esper as due to his powers being unrelated to AIM; it is believed that Imagine Breaker is beyond the current understanding of Academy City researchers.

   A person enrolled in this program is called an esper and, through a series of drugs usages and experiments, will be cut off from regular reality and enabled the capacity to substitute it with their own.[6] Espers are ranked according to their System Scan results, which evaluates six attributes to determine the rank of an esper: Precognition, Clairvoyance, Psychometry, Telepathy, Psychokinesis, and an unknown sixth one.[47] It is stated that Level 0 espers barely have enough influence to pass the curriculum's grading exams.[44]

   Any individual can use the curriculum to acquire powers, such as Misaka Mikoto, who started out as a Level 1 and worked hard during her training to become the 3rd ranked Level 5 esper in Academy City.[48] There are exceptions of course, as with the case of Level 0s. Furthermore, with the Parameter List, it is apparent that esper potential is limited by various factors. This has resulted in researchers determining that it would be wise to focus on developing an esper whose ability is worth more to the city and whose training is predicted to be more resource efficient than that of another person's.

   Information regarding the students enrolled in the curriculum, such as their abilities, their level and a brief description of them, is available in the Data Banks of Academy City. Furthermore, certain espers, such as Kamijou Touma, have security protocols in place to ensure that the truth of their abilities is classified.[44][49]

   According to Uiharu Kazari, the name of an esper ability, such as Electromaster or Telekinesis, is decided by the school that its owner is enrolled in. Only under specific conditions can the name of an esper ability be decided by its owner, such as the Railgun.[50] Railgun's editor Ogino Kentarou further elaborated later that there are three types of names for abilities: public ones, the ones that the esper themselves applied for and registered, and self-declared names.[51] It is unknown, however, as to what exact conditions an esper must meet to officially name their own esper ability, though its uniqueness may be a factor.

   Currently, only Academy City can create espers, although others have tried, such as during the Stargate Project.
