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's hard to believe you were the same 
person shouting at that huge army.
من الصّعب أن أصدِّق أنّكِ كنتِ نفس
الفتاة التي كانَتْ تصرخ في وجه ذلك الجيش الضخم
Es difícil de creer que estuviste
gritándole a ese ejército.
Es difícil de creer que estuviste
gritándole a ese ejército.
On ne dirait pas une fille
ayant tenu tête à une telle armée.
Non si direbbe che sei la stessa che parlava
 pomposamente davanti a una grande unità.
Difícil acreditar que você é a mesma pessoa 
que estava berrando com aquele exército todo.
