I don't believe you folks have met this girl yet. Her name is Mana Hale, a princess and a fire mage.

Here, we can see that she's trying to melt her chains after a semi-successful raid on an enemy castle. While she caused considerable property damage, her enemies managed to subdue her using one of their own mages.

I say "subdue," but the fact is that she extinguished her own flames and surrendered when another mage appeared. Poor guy just wanted a good magic duel, but he'll have to wait for another raid.
