Thank you for the upload, this manga is one of my favs. I think the male Gorgon Mei is going to clash with MIzudako, something like he is aware of her true ancestors (and maybe she's deemed as an enemy of the festival because of it). Maybe we'll get more lore of Mizudako's background and heritage from him. From what we've seen, I think her ancestry is more Cthulu than the beast of legend kraken, or maybe those are just the same thing.
I also wonder if the living statues in the cities were just petrified by the gorgons in a human & gorgon vs. evil demi-human fight long ago.
I also think the Akigai is slowly being changed into something more than human. It's funny that one his of dreams is exactly that to meet presumably the past Mizudako, he really loves her. The baku that was trying to eat his dreams said that it was a mental strain he eventually coudln't handle. Darin has the power to bring things to life, spike coffe like a potion/drug, and change him into Mr.Octopus (when he changed in the dream and then in reality after, idk what caused that, the butler?). It seems like Darin is corruption/madness against the norms of reality, maybe Darin will get more permanent the more Mizudako masters it or the more she uses it on him.
