What's the first Manga you ever read?

Elfen Lied. It was one of the first animes I'd ever seen, but somehow watching it I knew that had to be more. Went looking for a second season, only to find out that there wasn't one but also that the manga supposedly carried on much differently than the anime did. So I *cough* acquired it, and once I started reading I couldn't put it down. Well, metaphorically, since I was reading it on my laptop. But I loved it. I still have a fondness for the anime but the manga hit me in a much different way.
