Big Sister, Kindly Select Your Weapon
The Gilded Fangs Mercenary Group is one of many mercenary groups in Felin City. These groups are quite common, as many awakened individuals seeking purpose in their lives join to explore forbidden zones and hunt.
Klaus has already joined one himself—the Bloodaxe Mercenaries.
It was the group his father belonged to before he went missing. Klaus joined to gain access to forbidden zones and hunt. It's considered noble to join a group and venture into these dangerous areas.
There is a belief that the more people hunt in forbidden zones, the faster humanity will reclaim its lost Cities and forests. Thus, those who join these groups are viewed as noble by many.
However, just as there are white and black, there are noble and insidious mercenary groups. The Gilded Fangs Mercenary Group falls into the latter category.
