This chapter does seem to confirm that Kiriko is the main character, though. Her mother's forcing all of this on her even though she doesn't want it, and she'll probably have to either escape herself or burn the village down or something.
that feel when you notice the josei tag and realise that humanity won't have their revenge in the final chapter and it will just fade out with another downer ending of kiriko and the zombia vilagers murdering someone.
