The incident resolving girls have little to do with gender roles in the village. They aren't even allowed to live there. Two are mikos, whose western equivalent would be the oracles and shamans of ancient times. One's a witch, living alone in a forest hut (a more northern tradition). Sakuya is a maid at a vampire's mansion. The only one who's occupation is not completely feminine is the bunnygirl soldier Reisen, but right now she lives as the maid of a nurse witch and her princess lover. And since she's a little less woman, she's extra banned from the village, having to go in a disguise. Miko and Byakuren also live outside of the village as holy girls.
The village-dwelling girls Akyuu and Kosuzu, on the other hand, don't shoot bullets and live pretty much like girls in our world. It seems the human village has a culture where normal women live in the village and magical women live in temples or hidden huts outside the village. That means they very much have the gender roles this guy talks about within the village, and more obscure feminine roles like holy women and witches and battle maids exist mostly outside the village. That's also the way ancient Greeks, northern European pagans, and the ancient Japanese had it.
