Augusta Frederica Adel-Adler, known today as Frederica Rosenfort (ローゼンフォルト), is the Nordlicht Squadron's mascot and the last empress of the defunct Giadian Empire. She possesses a haughty demeanor and an outspoken nature due to her upbringing as the heir to the throne. Despite being young, she communicates with sophistication, which can sometimes be perceived as condescending by others.
She has the ability to see the past and present of a person known to her.
She is not afraid to argue her point and occasionally breaks protocol to get her way, such as when she snuck aboard Shineis transport during a sortie. When she was younger, she participated in boyish activities such as tree climbing, much to her knights chagrin.
