Well, there are several theories as to the failure of the ending of the anime: Supposedly, Studio VAP claims the series was not cancelled. But it is clear that they did NOT plan to end on the episode they did end on or in the fashion they chose to. A static shot of Gatsu walking out a door, without resolving the cliffhanger that ends volume 12 of the manga...well, that's either rank incompetence or a sign that they were either cancelled or expecting a second series. They didn't complete the Band of the Hawk story arc, so that clearly wasn't the reason they ended the way the did. The deletion of several key characters was done by the producers to make the series seem 'less fantasy'. Hence Puck and the Skull Knight disappear...which became a problem, of course, for the ending of the series. Media Blasters keeps trying to tell people every year that THIS year, there will be a sequel series. When you consider that the TV series encapsulates part of volume 1 and volumes 3-12...and that there are 29 volumes so far, it certainly wasn't from a lack of material. The show was rumored to have budget problems and it certainly skirted the edge with censors.
