The leader of 1121st platoon.
The 18-year old platoon leader of the 1121st with the rank of Second Lieutenant, Filicia is a young and very unorthodox officer. She bans referring to people by rank and instead prefers the sempai method. Gifted with a natural motherly personality she chooses to often take on the troubles and difficulties of others and hide the darker parts of military life from the other girls. She is best friends with Sgt. Rio and as uncustomary as it sounds often looks up to Rio even though she is a lower rank.
Lt. Filicia is a combat veteran and was the only survivor of a assault by her platoon, although rescued she was racked by survivors guilt and post traumatic stress disorder. It is assumed that her emotional well being is partially based on maintain the innocents and young spirit of those around her, this explains later choices that would otherwise seem to put the platoon in danger.
She is promoted at some point in the series to Captain.
