Install

is a function of Class Cards in the Ainsworth Holy Grail War that manifests the power of the Class Card's Heroic Spirit into the Card User.
==Characteristics==
Differing from the Include function that overtly manifests a portion of the Class Card Heroic Spirit's power as a weapon or ability, Installing utilizes the Card User's whole body to actualize the Heroic Spirit's power, granting the Noble Phantasms, Skills, and armaments of the Heroic Spirit of the card.
From the perspective of the Mage's Association of Illya's World, the existence of the Install function is completely unknown to them, first displayed by Chloe von Einzbern, then still residing in Illya's body, through the Archer Class Card. Within the Ainsworth Holy Grail War, it is a normal function utilized by all seven Card Users.
