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?
because I'm not strong enough!
!فقط لأنّني لستُ قويّة بما يكفي
also kann ich nicht als Einzige
nur danebenstehen!
porque no tengo ningún poder.
porque no tengo ningún poder.
Je ne peux pas rester
à ne rien faire !
perché i miei poteri funzionano a scatti!
porque não sou forte!
