An Esper (能力者 Nōryokusha?, lit. "Ability User") is a term used to refer to a person who emits AIM. Although, it is generally used to refer to people who have gone through Academy City's Power Curriculum Program. It is also used to refer to people who are powers, especially those who have gone through to the curriculum without gaining powers such as Level 0s and Skill-Outs. The term is also used to refer to magicians by those who are unaware of magic and can only rationally explain their powers by equating them as espers.


Index refers to espers as beings who have talent—most likely referring to Gemstones and as, such unable to use magic without causing much harm to one's body.[1] All espers emit AIM, which is unique to the esper's powers, for example: an pyrokinetic esper will heat up their surroundings unconsciously than any other person due to their AIM.[2] Furthermore, all espers have what is called a Personal Reality, it is the basis of an espers power and refers to the espers ability to replace ordinary reality with his own.[3] It is in contrast with magic's Idol Theory.

Regarding abilities, all espers can only have one type of esper power, for example: Misaka Mikoto is an Electromaster and is in control of all eletrical phenomena.[4] Although, this did not stop researchers from finding of ways to achieve more than power such as Dual Skill and Multi-Skill. In contrast however, esper powers need no such preparation and elaborate rituals to create some sort of phenomenon or effect in reality.

Moreover, esper abilities are categorized as either Active or Passive abilities. Active refers to an esper knowingly having to use his power to create an effect on reality, whilst passive has the esper subconsciously effect reality with their abilities. However, both can be present at the same time in an esper, such as Accelerator's subconscious reflection ability.[5]

Their distortion of reality to create powers is based on quantum theories. This distortion is an isolated phenomenon, pertaining only to the observations of the world by an esper based upon their Personal Reality. This is in startk contrast with holism, where a large distortion of the laws of the world as a whole is used to create powers.[6]

Power Curriculum Program

Main article:Power Curriculum Program

All those who enroll into the program are referred to as espers. The purpose of the program is to cut an esper from regular reality. Through the use of experiments, drugs and the like, a student can get cut-off from regular reality and achieve their own personal reality.[7] They are later given ranks depending on the results they have in a System Scan. It has been stated that even those who have a Level 0 rank have enough esper ability to barely pass grading on the esper curriculum.[8]

All espers are theoretically able to gain an ability or gain a level using the curriculum, such as Misaka Mikoto, a Level 1 at first becoming the 3rd Level 5.[9], of course, since there are exceptions such as the existence of Level 0s. Furthermore, with the Parameter List, it is apparent that there are certain limits that humans wanting to become espers using the curriculum, such as some having a slower development compared to the rest. As such, Academy City allocates their resources and money to the helping of students who would become an esper faster for example.

All those who have are part of the Power Curriculum Program will be listed within the Data Banks of the city, along with their power, level, as well as some comments regarding the person. Furthermore, certain espers such as Kamijou Touma have certain security protocols to protect the truth regarding their powers.

Currently, only Academy City is able to produce Espers; although others have tried, such as the Stargate Project.[10]

Gemstones and speculation

Main article:Gemstone

Gemstones are espers who are people who have not gone through any power development program, but is still able to emit AIM. They are most likely the beings that Index referred to as "talented", and the reason that ordinary beings created magic to compensate for their lack of powers.[11]There are currently 50 confirmed Gemstones in the world.[12]

In extension to this, it has been speculated that there maybe persons who have not realized that they have powers, or that their certain propensities or idiosyncracies, as subtle as good looks, or good penmanship may actually this power.[13]
