Hmm, well, just in case I'll post no spoilers. Lets just say that the manga has a MUCH different end then the anime, and I felt that the manga had more story to it. And better art. Just my opinion.
And watch me expertly tie this in with Grim Fandango: The woman who did Lola's voice in GF also did the voice of Kitsune in the dubbed version of Love Hina.
It fortunately is have such friends person's. I hat you.
