This is the worst anime I have ever seen. The reason over 5 times as many men as women have even BOTHERED to rate the series on IMDb.com is because... it's made for men. All it is is big breasts with nipples poking through skimpy prostitute-style outfits complete with garters plus machine guns and huge robots and fast cars. I also found the dialog very banal. My friend, who is a guy, recommended Burst Angel very highly to me (and now I'm not surprised why HE liked it) and I was thoroughly disappointed. Like Charlie's Angels, it had absolutely no plot. It was a cartoon version of Charlie's Angels except worse.
Also, what the heck is a Texas cowgirl doing in future Tokyo?! Would love to know that one.
