I must have gotten confused; I thought you'd posted on Netflixing something recently, which is why I mentioned it. They do have Disc 4 now, which is good, since it's the best one (but partly because of the way the others lead up to it).

I think you'd like this one, once you got over some of the silliness of the genre conventions, and especially once it gets going; like a lot of manga and anime, it starts out silly and gets darker deeper in.

I am ridiculously attached to the central couple in this one.
