It isn't really perverted at all... Well, maybe a little, but not much at any rate.
You can order the entire series (at least the first 54 episodes) directly from Animeigo. The manga was published by dark horse, and I am pretty sure you can still order it from Barnes and Noble. ADV released the mini-specials and the movie last year. (I've been plagerized before, so I'm very careful about making sure I buy something if it is available in my language -support the artists who bring us their vision).
As for the things you can't get in America:
Season 2
The Live Action Show
YUA: No Mercy (1 episode - Miyuki and Natsumi in LA)
You can find these as Bittorents
