A fog that seemingly mutates whatever it touches. I guess this is how the world must've ended. Her hamster was probably a product of it, but I wonder if she is as well. She couldn't have been this tiny from the very beginning.
I guess she is really tiny. I was thinking that car could've been huge, but in the past chapter the fruit they ate was big too. Not to mention all the giant creatures roaming about.
Reminds me a lot of the game Rain World except with fog instead of rain, or maybe even Knytt Underground since she's so tiny and living in the ruin if human civilization!
