An Involuntary Movement, better known as AIM (
This form is energy can only be detected via the use of machines  and is unique to the esper emitting it.
AIM is a weak energy that is unconsciously emitted by espers. It cannot be detected by the five senses, and can only be detected through the use of machines, barring espers who can actually sense them, or people like Takitsubo Rikou who can detect and even track the AIM of an esper.
AIM diffusion fields are apparently unique to the type of esper ability, as well as to the individual themselves. A few examples: Pyrokinetic Espers release heat enhancing AIM diffusion fields that heat up their surroundings whereas Telekinetic Espers release pressure inducing fields around them; Electromaster Espers release electromagnetic fields around themselves  where'as Accelerator Espers release vector alteration fields instead. When two AIM fields of the same nature overlap one another, they can cause an AIM Diffusion Field Resonance - increasing the strength of their AIM fields; allowing for a stronger manifestation of phenomena.
Given that the energy fields themselves are supernatural in origin, the Imagine Breaker can suppress the strength they have on their surroundings (nullify the effects they make), making it's owner the only known esper who is unable to utilize their AIM diffusion field, yet alone emit one.
Relation to Personal RealityEdit
Personal Realities are irreconcilably connected to AIM, as Personal Realities are the source of all phenomena manifested by an esper in the real world. The analysation of a person's AIM diffusion field can be used to figure out the nature of one's Personal Reality as well as the behavioural and personality traits of the esper emitting it. Personal Realities can also be abused via an interference made to the AIM diffusion field  and can also be modified through this as well. Following this, it would be apt then to say that an esper's AIM Diffusion Field is the conduit that allows an esper's Personal Reality the ability of affecting the real world; the manifestation of esper phenomena. Further more, since an AIM Diffusion field is found to be unique to the esper themselves,  it can be assumed that is due to the esper's Personal Reality. Such examples of effects that AIM diffusion fields have upon the esper's surrounding world are the one's emitted by Himegami Aisa as to allow her the ability to attract vampires, the one emitted by Misaka Mikoto that allows her the ability to produce electromagnetic waves that can move nearby wind turbines  and the one that acts as a thin field that surrounds Accelerator's body.
Despite all this, AIM diffusion fields can become unstable; when certain forms of interference are made upon an AIM diffusion field, it can lead to a simultaneous outbreak of RSPK Syndrome. Moreover, if an esper becomes so stressed or traumatized to the point of losing control over their Personal Reality (being unable to view reality properly), that would lead to an RSPK syndrome as well where the AIM diffusion field would affect the esper's surroundings in a similar fashion to that of an earthquake.
Relation to magicEdit
AIM diffusion field is not harmful to magicians, and despite the massive diffusion field that is aggregated in Academy City, magicians are not harmed when they enter the city and are unharmed when they use magic. Moreover, even if they are a hybrid, the presence of AIM will not harm the user. However, if a magician were to use an esper ability or an esper were to use magic, they would suffer grievous injuries due to the fact that magic and esper powers operate through different laws. This is extended if ever an aggregation of AIM diffusion is "brought out" into the world, specifically, the Imaginary Number District, which creates pressure in the area wherein it is located, making any magician overload and injure themselves.
AIM diffusion field technologyEdit
Scientists and researchers, such as the likes of Kiyama Harumi, devote their time to research AIM, and have facilities such as the AIM Analytic Research Center dedicated to it. It is also very important in the Academy City curriculum and is taught to students as early as a student's first year of middle school. AIM diffusion fields, as stated above, is also used to investigate the personal reality of an esper.
There has been plans to develop a restraining device to restrict the use of powers by taking advantage of the AIM diffusion fields of espers, though Shirai Kuroko states that the restraining device would be too dangerous since esper powers originate deep within the brain.
Technology such as the AIM Jammer is set up to diffusely reflect an esper's AIM diffusion field causing the esper to interfere with his own power, and the level of danger that an esper faces when confronted with an AIM Jammer is dependent on the fact that the esper uses complex calculations with their powers, though depends on the individual to what extent they need these calculations.
Aggregation of AIM diffusion fieldsEdit
One of the most important aspects of AIM diffusion fields is aggregating. AIM Diffusion Field Resonance occurs when espers with the same type of AIM diffusion field resonate with each other, causing effects of the AIM diffusion fields more prominent. Moreover, if they are overloaded espers, it could cause a massive RSPK Syndrome outbreak.
However, the prime example of an aggregation of AIM diffusion fields is the Imaginary Number District–Five Elements Institution, a separate realm that exists in the same location as Academy City, and is formed through the millions of AIM diffusion fields of the espers that reside in the city, which is one of the core tenants of Aleister Crowley's plans.
- Main article: Artificial Heaven
So far shown, artificial angels, or more precisely, artificial beings, since they do not follow the laws of any religion, are formed through the AIM diffusion fields of espers. The likes of Kazakiri Hyouka, which is molded by Aleister Crowley, and the AIM Burst, which is an aggregation of the AIM diffusion fields of the espers of the Level Upper Network, afer Kiyama Harumi lost control of it, can be referred to as Artificial Angels.
Artificial angels have queer powers. For example, the AIM Burst have the ability to use all the powers of the espers that are connected to the Level Upper network, whilst Kazakiri Hyouka exhibit tremendous self-regeneration and strength, among others.
As they are merely an aggregation of AIM diffusion fields, they are most likely be able to be dispelled by the Imagine Breaker. In fact, Kazakiri Hyouka's consciousness was born out of the fear of the Imagine Breaker.
Similarly, espers such as Accelerator and Kakine Teitoku, whose powers are unique and have divine properties, can Awaken and gain greater control of their AIM fields, allowing them to update the very laws of reality themselves. In Accelerator's case, his wings are an expression of his AIM diffusion field.
- ↑ Takitsubo Rikou's AIM Stalker allow her to memorize the AIM diffusion field of an esper. One can extrapolate that all AIM diffusion fields are unique to the esper.
