The anime began airing in Japan on January 6, 2005 and ended June 29, 2005. The anime follows the story of the manga to a certain degree but also creates its own reasons for certain events happening - most of which take place towards the end of the series - which differ from the original story, as the situations addressed had yet to occur in the source material. The differences between the manga and anime are significant, and most events in the manga never occur in the anime, again due in part to the manga being incomplete during the series' production. Starting in episode 22 and continuing until the end of the series, original work was created so the series would have a conclusion. At one time it aired as part of the Funimation programming block on CoLours TV.
