Heroic Spirit

Heroic spirits (英霊 eirei) are heroes who have achieved greatness during their lifetime, and have become the object of beliefs after their death. They are higher existences who have the power to "protect humans", and their classification is closer to spirit than ghost. A spirit is a "power" materialized through the mainframe that is the image people have of it; based on that, a heroic spirit is the compilation of what humans idealize of him.

Amongst heroic spirits, there are "Guardians" that have no legend, that were not observed or believed in, used by a mindless "Counter Force". In the original story, Archer is the only heroic spirit that is one of those "Guardians".

The other heroic spirits have a higher divinity ranking, closer to the existence of a planet than of a human, and are not counted as Guardians.
