Souseiseki

The fourth Rozen Maiden doll, and Suiseiseki's tomboyish twin sister. As with Suiseiseki, she is a gardener that has the power to enter human dreams, and carries a set of pruning shears that she uses to tend humans' soul trees. She wields these in battle combined with acrobatic flight, her spirit Lempika and her hat which can be thrown and returns like a boomerang, a tactic she used to temporarily disarm Shinku in their second fight. She also has heterochromatic eyes like Suiseiseki, but the colors are the mirror image of her sister's. Her personality is also the polar opposite of Suiseiseki; she is rational, calm, quiet and deeply devoted to her master and to her duties, including the Alice Game. She possesses a sharpness in her speech that is similar to Shinku's, attacks ruthlessly in combat, and does not tolerate sub-par actions. Her appearance is not only the most masculine of the dolls, but her speech is also noted to be of the masculine form, using the first person pronoun "boku" instead of gender neutral pronouns like "jibun" or "watashi." Souseiseki's presence is much more significant in the anime than in the manga.
