This anime must be one of the most disappointing stories in all that I have ever heard, read, watched, etc. The potential this anime had to become an absolute masterpiece, a testomony to the craft which comes from this kind of art was unmatchable. But....
it failed. Everything from episode 1-11 was all a build up for the worst ending I have ever seen. The manga is no excuse either. So excluding the ending this series served the great purpose of a light-hearted anime with roots.
