This is by far, my fav anime... I stopped watching anime from the years 1995 to 2007.. I saw a few anime movies in that time, but I'd mostly lost interest in animes... It was this anime and Vandread that got me to start watching anime again, and its became my obsession ever since. Now I watch anime, everyday. I'm not really sure what about this anime that caught my interest, it wasn't the first episode, I actually saw several episodes into it, before I went an watched it all from the beginning, when Teresa was in the anime, the prequel if you will is when I first saw this anime. It wasn't the kiddie anime I'd seen years earlier, it was hardcore, gritty, action packed, an anime that had teeth, and wasn't made for children. Its the anime that got me to love anime all over again as an adult.
