Укрощение поля костров

"Build a fire - night comes... Light a fire - darkness comes... Hide the fire - flames arisen from corpses creep in..." Ginko meets another Mushi-shi, which happens to be a young lady called Yahagi and surrounding the village she lives in is a new variety of Mushi growing on the mountain's fields. It's becoming so bad that the village people are at risk and as a last resort they plan to burn the entire mountain but Ginko doesn't think that this is the right option.
