カティア・ヴァルトハイム

Originally a member of the West German army, Katia was rescued by the 666th TSF Squadron after the rest of her unit was destroyed. She later applied for refugee/defection status, but was instead transferred to the 666th as a replacement pilot, at the recommendation its members. This odd occurrence has initially drew the suspicion of Theodor and the Stasi.

Though she has little experience as a TSF pilot, she possesses natural talent and instinct, which are things that cannot be taught, which is why people view her as a potential ace pilot.
