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?
It seems you insist on facing my wrath, then.
يبدو أنّكم مصرّين على مُواجهة غضبي إذاً
Es bedarf wohl erst
der eisernen Faust.
Parecen insistir en enfrentarme.
Veo que insistís en hacerme frente.
Je vais finalement devoir
vous frapper de mon courroux.
Come temevo,
Parece que insistem em
 encarar a minha fúria.
