Here is concept of a new girl for ROAG and its successor.
The design is of the leader of the goddesses at the canals of Las Diosas. Just like it was in the mountains, the canals were a place where the goddesses in training could practice their naughty combat techniques, it wasn't a place of hiding but a place to go to have more privacy. But after the hunters took over, the canals became a place for the apprentices to hide. After they were forced to flee they kept training, but also becoming more dangerous waiting for a good time to strike. The gals at the canals are more aggressive than the ones in the mountain, and their leader will reflect that.
I'm still planning on what name to give her, and she'll have a couple of friends that might give you some trouble before you earn their trust in the final mission of ROAG coming soon.
