cold resist

“...Oh, Kanzaki. Aren’t you cold dressed like that in this February weather?”
The shop owner had his arms wrapped around himself and was shivering. In London,
February was the season of snow. And that year all of Great Britain was wrapped in the
kind of cold wave that would kill the little match girl. Small lakes were frozen solid
enough to walk over.

And yet Kanzaki had one of her legs completely bare up all the way up the thigh.
“Not really.”
“Unbelievable...”
The shop owner had blue lips, visible exhalations, and was dressed as thickly as
someone taking on Everest.
