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?
I can't just sit back and watch
when everyone is in danger
مكتوفة الأيدي وأكتفي بمراقبةِ الجميع 
يتعرّضون لخطر
sind alle in Gefahr, weil ich
nicht mächtig genug bin,
quedarme aquí mientras corren peligro
quedarme aquí mientras corréis peligro
c’est mon pouvoir instable
qui les met en danger…
non posso certo starmene qui a guardare
Não posso ficar sentada vendo
 os outros correndo perigo
