Note: This is a reference to the third week of Fate/Extra, wherein the enemy Servant activates a Reality Marble called Nameless Forest, capable of making people forget their identities.
When the player character finally figures out how to counteract the Reality Marble's effects, the player can either choose to have the player character affirm their correct identity or affirm that they are called Francis Xavier (as a joke answer).Congratulations
