Rita was a childhood friend of Shin before the war began, often playing with each other as their parents were friends. During the first year of the oppression against Eighty-Six by the government of the Republic, Rita's family provided shelter for Shin's family to hide from the officials. That was until Rita was bullied for being friends with a Colorata boy. She asked her father to kick Shin's family out of their home; as a result, Shin's family was sent to the Eighty-Sixth Sector.
After her father was killed during the testing of the Para-RAID device, she took on her father's role as a developer. Although it was stated to be an accident, her father took his own life. He was unable to bear the guilt of betraying the Nouzens and engaging in human experimentation. Annette also bears regrets of betraying her childhood friend. She understood the true situation of the Republic, but did not have the will to change it due to feeling powerless.
