Sorry, forgot to reply to this. Good reference, and she's definitely gonna be freaked out by the hideaway dingaling (possibly even more than the tail). And, for your reference, Kaine's got a mostly standard vulva, with two important differences: no urethra (in that part), and her clitoris grew into a full-sized penis (which is where her urethra goes; not that that's likely to be important). Also, her dick is, uh... big; I generally picture about 8", since they make a point of commenting on the size in one of the grimoire nier short stories.

Another thing Oran might notice, by the way, is that Kaine's body is strong as fuck; she can pretty easily leap 4 or 5 stories straight up, and cut a monster that size in half with one swing... the long way.

Anyway, here's her starter!
