It's a shame the sequel doesn't seem to have been scanlated at all. It's about Balsa a year after the events here, going to her homeland iirc. I think there were 12 novel volumes in all covering 9 stories, only the first one got animated and first two adapted to manga (but like I said, the second part doesn't seem to have been picked up by anyone). Scholastic did a localization of the first two novels, but poor sales seem to have killed that off, and the fan translation I could find didn't complete volume 3, let alone start any of the others. Guess I'll have to chalk this series up as yet another reason to properly learn Japanese myself, and someday maybe the list will even defeat my laziness.
