Cristiane's father's main subordinate and the commander of the special squad. Margit transferred to Kawakami Academy to take care of Christiane Friedrich while Chris is enrolled in the academy (Under the request/order from Frank), but she was also worried about Chris, since she had knew her from an early age.

She has a sister relationship with Chris, affectionately calling her "Maru-san".

Even though she's already graduated from high school, Margit was allowed to enter class 2-S, because Kawakami Academy values strength of the people more than anything. But she refuses to use the uniform of the academy, and prefers to use her military uniform.
