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?
If I could use it everywhere, I could 
live up to everyone's expectations.
لو كنتُ أستطيعُ استخدامها في أيّ مكان
لارتقيتُ لتوقُّعات الجميع
Wenn ich sie nur überall einsetzen könnte,
müsste ich niemanden enttäuschen …
Si pudiera usarlo donde fuera,
estaría a la altura de sus expectativas.
Si pudiera usarlo donde quisiera,
cumpliría sus expectativas.
Si je pouvais l’utiliser partout,
je pourrais satisfaire vos attentes…
E pensare che, se potessi usarli ovunque,
Se eu pudesse usar em todos os lugares,
 eu atenderia às expectativas de todo mundo.
