Looking for good anime/manga...?

Ranma 1/2 is one of my all time favorites. It's definitely about martial arts and romance and they show boobs, if that's what you call mature. It's really great and funny. I think the manga is 32 books and the tv series has I think like 5 season or even more if I'm not mistaking. Other favorites include "Love Hina" and "A.I. Love You," they are great too. A.I. Love You is not an anime, only manga.
