Notes: This unit, designated Witch-Type Anomalous Neuroi X-11 by the Allied Office of War Information, is history's first known Neuroi defector. It (she?) is believed to be the same witch-type unit that attempted unsuccessfully to contact the 501st Joint Fighter Wing in 1944 and the 504th in 1945 (Operation Trajanus), despite that unit's apparent destruction in both incidents. Exactly how this can be is not currently known, as full communication has not yet been established, even by the witches X-11 evidently considers friends.

All that is known for certain is that this Neuroi unit, having assumed the physical configuration of a combat witch, has abandoned the invaders' forces and joined the 501st JFW. In that capacity, she has served thus far with distinction, playing important roles in several operations and performing exemplary (but still classified) personal services to the Crown of Karlsland as well.

In recognition of the latter, Kaiser Friedrich IV created a cadet branch of his royal House of Hohenzollern and adopted the Neuroi defector into it. He also commissioned X-11 an officer in the Luftsreitkräfte, a reincarnation of Karlsland's Imperial Air Service from the Great War, which now constitutes an extremely small special flying corps bearing the Kaiser's personal imprimatur. Enrolled under the name "Winifreda von Hohenzollern", she holds the title of Knight of the Order of the Black Eagle, a chivalric order reserved for members of the imperial house and its closest retainer families.

Precisely what X-11/Winifreda (or, as her friends in the 501st universally know her thanks to Yoshika Miyafuji, "Neuroi-chan") makes of all this is unclear, as despite her obvious goodwill and steadfast loyalty to her comrades, she remains silent and largely inscrutable. However, she has altered her outer shell to display the Star of the Black Eagle prominently on her chest, indicating that she does at least understand the honor—and perhaps even appreciates it.
