The complete thirty episode series is licensed for Region 1 release by Bandai Entertainment, in Region 2 (Europe) by Beez Entertainment and in Region 4 by Madman Entertainment. The series was adapted into a short two-volume manga series written by Keiko Nobumoto and illustrated by Toshitsugu Iida. The manga, which was released while the series was airing, is a retelling of the story rather than a straight adaptation. It was originally serialized in Magazine Z and has been released in North America by Viz Media.
The anime series was well received in Japan, being the third-ranked anime series in its timeslot while airing on Fuji TV. The Bandai Entertainment English-language release sold well in North America. It helped Bandai gain the 2004 Anime Company of the Year award from industry news company ICv2 in the ICv2 Retailers Guide to Anime/Manga. The manga adaptation was selected as one of their top ten anime products of 2005 and sold well in North America. Reviewers of the series gave it high marks for characterization, visual presentation and its soundtrack, while disparaging the existence of four recapitulation episodes in the middle of the series. The manga adaptation also sold well in North America and received good reviews, though reviewers felt its short length resulted in a rushed plot and neglected supporting characters.
