Okay, so the blonde girl is a magic-user and carries a magic staff in battle. Makes perfect sense. The question is, why is catgirl going in unarmed? Is she just there for the eye candy? Shouldn't she have, at least, transformed and torn the goblins with her claws?
Normally, by the time they get to wear that not-quite-there armor, they should be stronger than the female knight. The less armor, the more powerful an adventurer, right?
What rank was that guy anyway? How did he managed to get to that rank if he didn't even have presence of mind to do a proper retreat?
