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?
And so these are the areas in 
which she can use her magic?
إذاً أهذا هو النِطاق الذي تستطيعُ ضمنه
استخدام سحرها؟
Und das sind die Gebiete,
in denen sie Magie einsetzen kann?
Así que esta es el área
donde puede usar su magia.
Así que esta es la zona
donde puede usar su magia.
Et donc, le rouge indique les zones
où la magie fonctionne ?
Dunque,
E esses são os lugares em
 que ela pode usar magia?
