Everyone is thinking Croi is looking to overthrow her mother, but I'm not so sure. There are a ton of different monstergirl types in the world, what if what we saw was a shapechanger?
What stood out to me about this update was Yakuu visiting all these little neutral towns apparently to the north of Hornsperia, which is where the border between Viridice and Lycolis is- and given she met with a Lycolis giantess who knew her well, im thinking she's the one behind the false flag op between Viridice and Lycolis.
You remember my theory about the shape changer? In Naya's route, the guards at the tomb where killed before they could react- what if it was because they thought they were seeing Naya, but it was actually Croi/the shape changer?
