This two-episode Rozen Maiden special was aired on December 22 and 23, 2006 on TBS in Japan. It is a brief prequel to the events of the TV series. OuvertĂŒre (ăȘăŒăă«ăă„ăŒăŹ, ĆberuchiyĆ«re?), German for "overture", is set at some point during TrĂ€umend (most likely between episodes six and seven) and answers critical questions about Suigintou's past, particularly those pertaining to the rivalry she holds with Shinku. The majority of the two-episode special is told by Souseiseki and takes place as a flashback to the nineteenth century in London. Ali Project once again lends its talents for the opening song. As with the series, Kukui sings the ending theme.
