Gemstone

A Gemstone (原石) is the term used to describe an ESPer who was born with their powers. There are few of them in the world and many aspects of their powers can't be described using scientific methods. In difference with artificially developed ESPers the gemstones emmits larger amounts of AIM field from their bodies.

Kamijou Touma doesn't belongs to this group because his powers are not AIM based. A member of the Academy City board of directors, Kaizumi Tsugutoshi, once had a conversation with a helper he hired from Kamijou Touma's school (Kumokawa Seria (雲川芹亞)), and came to the conclusion that the Imagine Breaker is not a gemstone and is probably something beyond their understanding.
