One thing I liked a lot in this update was in Regina's route, we finally got another hint as to the MC's past, as well as I think a reference to the very beginning of the game. If he had been dreaming about Kendra I think he would have remembered it, but the mention of a "wicked smile" I think aligns with what we saw of that giantess at the very, very beginning of the game.
I'm really liking all the new side characters in Lycalis & Viridice, those two kingdoms felt very barren in terms of characters for wayyy too long.
If there weren't so many routes already I would've loved to have routes for the two new Viridice ladies. Hopefully they'll have their time to shine once some of the main routes wrap up.
Then as you say, this was appreciated as well- it's a bit of an interesting hierarchy Viridice has with its leadership. In Keisema, the former main guardian was the queen, and that title was passed down to her daughter post mortem. In Hornsperia, it seems to be the case that there is no monarchy (though that may be incorrect, but I can't imagine a place like the Hell Kingdom having a king anybody would respect) and instead is just ruled de-facto by Yakuu and Pyeka. Then in Lycalis, Naya holds a dual position of matriarch and guardian, but in Viridice Regina is not the queen, she's just the guardian, as the reveal of the princess showed.
I don't know I just find it interesting.
