Ever since Ottilie participated in battle, she has been Flight Lieutenant Nowotny's wingman. She even exceeded Nowotny when it comes to kills, making her an outstanding ace, even in Karlslandian standards.
Kittel is a young genius who flourished while fighting next to Nowotny. Kittel adores Nowotny as her "Destined", but her slight greed over money and food can sometimes grow stronger than those feelings.
Kittel was worrying because her kill count would soon exceed Nowotnys, so she changed to a shift that Nowotny wasn't in, and stopped reporting her own kills. In reality however, Kittel's kill count indeed grew bigger than Nowotnys, but she was seemingly in a slump with no new official kills. Nowotny got worried and kept trying to help her. Eventually Kittel revealed the whole thing and Nowotny praised her greatly instead of getting angry.
She is the top ace of the 503rd JFW with the most shot downs.
Ottilie love Waltraud Nowotny and call her "Nowo-sama".
- She is based on Otto Kittel, credited with 267 aerial victories and was awarded the Knight's Cross of the Iron Cross with Oak Leaves and Swords. He was shot down by Soviet aircraft and killed in February 1945, making him the most successful German fighter pilot to be killed in action.
