An Involuntary Movement

An invisible energy field that the espers involuntarily produce. One example of this is when Tōma finds Misaka Mikoto by following wind turbines that are turning without wind. Mikoto's body involuntarily produces voltage all the time; thus Tōma comes to the conclusion that it can power the wind turbines. Another is the Accelerator's "default" setting to automatically deflect any energy or matter that approaches him.

Thanks to extensive and highly illegal human experimentation, the city scientists were able to create a reality altering entity from the combined AIM of the city's residents, Kazakiri Hyouka. She normally exists in a shadow dimension, the city of shimmers, unable to interact with people, but altering anything that attracts her attention. Contact with magic users allows her to temporarily manifest in the real world as an immortal entity; any damage she takes, even to her clothing, is repaired in a few minutes. It is unknown how or if Imagine Breaker will affect her; it is theorized that as a living entity she is immune, despite her power-based origins, or that she will be rendered a normal human, but Toma has gone out of his way to avoid touching her, for fear of killing his friend. The novels (specifically volume 6) themselves state that should Kazakiri comes into direct contact with Imagine Breaker she would be erased, since even if she's alive she's made of the AIM dispersion field, and as Imagine Breaker wipes out supernatural effects regardless of it being good or evil she is no exception.
