Barasuishou

薔薇水晶

Barasuishou is a doll created by Enju, Rozen's apprentice, who introduces herself as the seventh Rozen Maiden doll at the start of Rozen Maiden träumend. This is a lie; she simply intends to dupe the other six Rozen Maiden into entering the Alice Game so that she may obtain their Rosae Mysticae and become the strongest doll. [Spoiler] Barasuishou does eventually acquire the other six Rosae Mysticae, but cannot contain their power since she is not a true Rozen Maiden, and ends up shattering in Enju's arms. Barasuishou only appears in the träumend anime. [/Spoiler] (Source: Wikipedia)
