Im suprised not more people have read this, but at the same time i can see why.
Only 10 chapters and 2 volumes, that is not much, especially not if the first chapters show you the picture a large living world with it's own unique features.

After reading some other reviews i found out that the author died. That explains a lot, since this manga has an extremly abrupt ending. Which may really shock you since the first five chapters or so speaks of a large and interesting adventure that may go on for a few volumes or so.

However, i really enjoyed it and the artstyle is pretty good.
