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?
And now, they're being wiped out
by a single girl.
وها هي يتمُّ دحرها بواسطة فتاةٍ واحدة
Und nun weist es ein einziges
Mädchen in die Schranken.
Y ahora una sola chica puede vencerlos.
Y ahora una sola chica puede vencerlos.
Mais une seule fille
a été capable de les humilier.
Ma viene battuta da una sola ragazza
E agora estão sendo arrasados
 por uma única garota.
