A Mascot was a type of military personnel whose role it was to reduce thoughts of desertion within the military of the Giadian Empire and Federal Republic of Giad. A Mascot was generally a young girl which would play a little sister or daughter role to a squadron's soldiers, forming a sort of family bond between them. As the soldiers would become attached to the Mascot, they would be incentivized, even to the death, to protect her. One such Mascot is Frederica Rosenfort.
As the origin story went, a Mascot was first used as a hostage to keep mercenaries from desertion in the Giadian Empire. As the ages went by, the Mascot system was phased out of the military; only a few squadrons in the Federacy kept up the tradition. Eugene showed surprise when he learnt of the Nordlicht Squadron still upholding the Mascot system.
