"What the hell are you doing?! Shoot her!!" ordered the guardian captain while taking a distance.
Unfortunately, his stern order fell on deaf ears. Moreover, unlike the sluggish Gram monster, Brigida didn't give the captain any breath and kept making close contact. This is the big difference between fighting an experienced combatant and a mindless monster.
As the guardians used to fight against the monster all year long, they didn't expect such a situation. Their rigid minds also couldn't find an immediate solution to this sudden battle.
Even if they could think of a good solution, the other guardians are preoccupied with Angus' spells. Despite being unable to damage the guardian significantly, it didn't mean his spells were utterly useless.
In fact, just a small explosion produced close to their face is enough to make the guardians falter and interrupt their battle mage casting. On the other hand, the guardian captain is getting more restless.
