Symphogear post G: Airgetlám

An energetic singer who reached the top of the American music charts about 2 months after her debut. Although it has a mysterious quality, her vigorous singing voice has crossed over international borders and garnered a large number of wild and enthusiastic fans throughout the world. To bring forth justice, she has risen as an enemy against all of humanity, clad in a Black Gungnir Symphogear that is outside of the Japanese government’s control.
