I wonder if the big theme of this story turns out that Kuzuryu's grasp on physical reality is particularly tenuous, which is why she can slip into imaginary roles so easily, and also perceives animals as sentient humanoid creatures.
I like how Miho trusts Wanko enough to let down her fake nice personality around her, and Wanko has learned to not take Miho's salty remarks personally. It feels like they've become actual friends over the course of this manga.
