Principles Īn illustration on how Personal Reality, AIM diffusion field, and esper power interact, as depicted in the Astral Buddy manga.Īcademy 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. Abilities such as Pyrokinesis are considered esper powers despite the user not having extrasensory perception. 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. Because of this, the English fans that were accustomed to the use of "esper" lobbied for "psychic" to be changed, and Seven Seas acquiesced, even referencing the incident later. Because its use has become widespread, this wiki uses the term "esper".Ī queer event related to this is Seven Seas' English translation of the first volume of A Certain Scientific Railgun, which opted to use "psychic", a term that has been used before by the fandom until "esper" became the standard. The original Japanese light novels used the term "Ability User", but before the licensing of Toaru Kagaku no Railgun, the majority of the English-speaking fandom substituted it with "esper". In-universe, espers have only existed for a few decades up until this point. 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. 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. "Ability User") is an individual who uses scientifically based supernatural powers and emits AIM.
