With Izetta's victory over the Germanian army fresh in people's minds, the army of the Dukedom decides to make her into a national icon and announce her to the world.  She's given the finest white dress they have to offer and a huge ceremony is arranged with journalists from all over the globe.  But before she can be used in combat, they need to unravel the secret of her strength, which means she must travel to a hidden location with a girl who doesn't like her very much at all.
Who would've thought such a thing 
existed under the castle...
...من كان يتوقّع أنّه يوجد شيء كهذا تحت القلعة
Kaum zu glauben,
dass es so etwas unter dem Schloss gibt.
¿Quién habría creído
que eso estaría bajo el castillo?
¿Quién habría pensado
que habría algo así bajo el castillo?
Qui eût cru qu’une telle chose
se cachait en dessous ?
Chi l'avrebbe detto che nei sotterranei del castello
ci fosse una cosa simile...
Quem diria que teria algo
 assim sob o castelo...
