Tenchi Muyo! Alien Nation

My cousin suggested this to me after learning that I do like some anime/manga. It was hilarious. The setup one eighteen year old boy lives with five alien beauties who ALL have a crush on him in some way or other. That's right, every male's day dream. However, Tenchi is sweet, and sometimes a little clueless. He permits the women to be themselves, but isn't settling down with any of them. Hence high jinks ensue. The one thing that saddens me, is I was trying to get the first of all the series because I like traveling with characters through it all, but I can't seem to find what the beginning is.
