As you might guess from her antenna design, her nickname is "Unicorn"; her familiar is a crow. She doesn't have any real battle experience to speak of (though she's great at hand-to-hand), but she was assigned to be Oberst/Colonel Fichter's guard (the guy in that picture above) after she protected him from a Neuroi that appeared suddenly while he was visiting her officer school.
