Performa

Performa is the manifestation of an individual's creative energy in the universe of Genei Ibun Roku♯FE. This energy comes from a person's drive to create or perform, whether that be through acting, singing, dancing, or other activities. Mirages, entities from another world, are drawn to Performa, and hostile Mirages will attack humans to drain this energy from them. People that have had their Performa drained are overcome with a sense of hopelessness and despair, as their creative will has been taken from them.

Individuals that boast unusually high levels of Performa have the potential to become Mirage Masters, or people able to form bonds with Mirages by willingly sharing their Performa.

Etymology
Performa is derived from the English word "perform," or "performer."
