is a Japanese anime television series created by character designer Mutsumi Sasaki and planner & scenario writer Hina Futaba. The series was produced by MediaWorks, King Records, Lantis and Yomiko Advertising and animated by Feel, Studio Flag and Ufotable. It ran for 13 episodes from 7 April 2005 to 30 June 2005.
