I am, in fact, slowly reading the archives of Gunnerkrigg Court (because of your having mentioned it before), and although I've only read a couple of volumes of Sugar Sugar Rune, I like it muchly and keep meaning to order more of the older volumes that are never on the shelves when I think to look. I generally like Anno's adult work better, but Sugar Sugar Rune is unique.

I would be awfully curious to know what about those searches led to you. I've had the mechanics of search engines explained to me generally before, but not much of it stuck.
