Yaeko seems to have gotten off lightly in the transformation department. There are blue-black fox ears poking up through her hair, and she seems to be contending with anywhere from one to three tails at any given moment, but that's it.

Perhaps the powers that be realised she would be extremely put out if she were unable to draw anything. Seemingly more so than usual, her sketchbook is a constant companion; odds are high she'll ask anyone who hold still long enough if she can draw them.
