Gentle Old Woman

Gentle Old Woman (落ち着きある老妻 Ochitsuki Aru Rōsai) is likely the Nive Village Chief's wife, as they live together in the big house in the north part of the village, between the well in the northwest and the Apothecary's spot.

She mentions that Setsuna is chosen by fate just like her mother. The old woman wants to at least make Setsuna some arctic cauliflower soup, because she knows the girl likes it a lot.
