Existence Value

Existence Value (存在値) also known as Energy (存在力) is the energy (Magicules, Magic Power, Aura, etc) contained within the body and soul of an individual or object.

Existence Points
An objective and numerical measurement of Existence Value called Existence Point (ＥＸＩＳＴＥＮＣＥ・ＰＯＩＮＴ)—shortened to EP (ＥＰ)—was created by Tempest utilizing the precise analytical powers of Ramiris's Small World, acting as the basis for their internal Rank system. It's an improved and more precise version of the rudimentary measurements utilized by the Eastern Empire.
