The Fairies
That marauder camp was the first one on their list. Every week, after consuming their [Gaia Serum], Emery would go with the girls to eradicate any bandit group they could find from Southern Briton.
Most of the targets were selected through information gathered by Gwen and Luna.
The fact that it was not hard to find a new target was a testament to how chaotic the current situation was in southern Briton.
The invasion of the Cantiaci Kingdom merely added fuel to the fire and the amount of bandits hanging around what was once Lioness territory became practically endless.
Most of the time, Emery did not join the fight, as the girls were more than capable of taking care of themselves. However, there were some outlying cases wherein the girls would be overwhelmed.
