I thought there was more to come for
Yukikaze, but to be honest I don't really know. I'm curious about that as well - it would be a rare single disc series for me if it was complete.
EDIT: My wife is definitely not an anime fan. She has the notion that it's all about "mouse-girls with big eyes and big boobs". I want to pick up
Grave of the Fireflies and watch that with her

. My daughter shows interest in it, but she's only 4. I figure she should be at least 5 before I start watching
Elfen Lied or
Gantz with her

. Seriously though, she does need to be a bit older to watch the stuff I'm interested in.
