Wait, in the village there is the statue of the dragon god who glow red when there is something like this.So why the villagers are so surprised and they did not get prepared for this.
Red is for "something truly strange". Which is vague to the point of uselessness, and wouldn't show up for a natural event like this
Tengu are like beast, they can anticipate this kind of thing.
...That is not the impression I got from Aya's story path in SWR
I think this is an excuse of Zounose for the drama.
Aren't all story events excuses for drama?
