Izetta is powerful enough to fight whole armies, but her strength is limited.  She can only use her abilities near certain ley lines, and outside them, she's no different than a normal girl. When the Germanian army attacks in a spot far from these ley lines, the duchy is forced into a corner: how can they repel these foes without giving up the secret of Izetta's strength?
Nobody could keep up with her in a dogfight.
لم يستطع أحدٌ مُجاراتها في نِزالٍ جويّ
Kaum einer könnte in
einer Luftschlacht mithalten.
Nadie podría seguirla en combate.
Nadie podría seguirla en combate.
Personne ne ferait
le poids dans les airs.
Dubito ci sia qualcuno in grado 
di eguagliarla in una battaglia aerea.
Ninguém é páreo para 
ela em uma luta aérea.
