That makes more sense XD. Hmm, tbh it just depends on what I feel fits their theme/personality when I'm drawing them. Wolves are pretty predatory after all.
Yeah, I was considering bat for Rinny. The only reason I'm not doing a furry form for her is because she has way too many poses and I don't really want to have to make furry versions of all of them XD. That and her being a succubus will be an important plot point later on.
