Augusta Frederica Adel-Adler, currently under the name Frederica Rosenfort (ローゼンフォルト), is the Mascot of the Nordlicht Squadron and the last empress of the former Giadian Empire.

Frederica is haughty and outspoken, as she had been raised to be the next in line for the Giadian throne. She articulates her speech maturely for someone her age, which often rubs others the wrong way.
