Barasuishou is an impostor, claiming to be the seventh doll. She mirrored Kirakishou to trick the others into thinking she was the seventh Rozen Maiden.She was the seventh doll to appear in the anime and debuted in the first episode of Träumend, but does not appear in the manga. Barasuishou's personality is highly mercurial and unpredictable. She almost always appears emotionless, even as she mercilessly attacks the Rozen Maidens in order to gain their Rosae Mysticae. She apparently cares very much for Enju, even if she does not typically express her feelings. In episode 12 of Träumend, when she demands Shinku's whereabouts from Jun Sakurada, she displays obvious anger as she attacks him. Later, she giggles and smiles disarmingly when Shinku pins her down to the floor. During the episode's climax, her eyepatch falls off and her face contorts with fear, and she begins to cry as her body and face start to crack. It is then shown that Barasuishou had no real need for the eyepatch, since her left eye appeared normal, and that the eyepatch was most likely a seal over her emotions.
