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?
Then the whole world
will be forced to acknowledge
حينئذ سيضطرُّ العالم كلّه للاعتراف
،بوجود السّاحرة
So wird die Welt keine Wahl haben,
außer sie zuzugeben –
Entonces, todo el mundo tendrá
que aceptar la existencia de la bruja
Entonces, todo el mundo tendrá
que aceptar la existencia de la bruja
Le monde sera alors obligé
de reconnaître son existence,
In questo modo,
Assim o mundo todo será obrigado 
a admitir que a bruxa existe mesmo
