The only info about the glasses-wearing demon is she's wearing Maijima uniform, nothing else.

Spoiler:

This is a refreshing revelation regardless. I assume this would mean Akari takes off her scarf (while Keima isn't there) to reveal her explosive guillotine leash in the chapter? As for Nikaidou, if the photograph of her high school years is genuine, she could indeed be human. However, I am still hoping for the near-zero possibility that they are both demons~
