Ecomichi Company

The Ecomichi Company (エコミチ社) is a company which produces materials for the development of esper abilities.

Principles
The company manufactures a number of products meant to assist in the development of esper abilities, including electrical stimulus materials.

Background
The company's products were the subject of a rumor concerning their products causing an esper called Ishigaki Miho (イシガキミホ) to lose control of her powers, leading to her being expelled from her school. However an official investigation by Judgment and Anti-Skill couldn't find any evidence of the incident or Ishigaki Miho's existence, concluding that the incident didn't actually occur.

Though the rumor was false, Aizono Mio used it and the identity of Ishigaki Miho to manipulate the Disciplinary Guides. During the investigation into them, Uiharu Kazari found the official report on the case and later read it to the Guides after they were apprehended.
