A karakasa is a Japanese umbrella ghost. It's an old paper umbrella with arms, one big eye, a tongue hanging out of its mischievous grin, and instead of a handle, it has one leg wearing a wooden sandle. It hops around and scares people for fun. So this girl's mimicking a karakasa or something. I dunno. Her anatomy is weird, but I don't care, because she's supposed to look twisted and inhuman.
