Fantasy: 3rd Rozen Maiden

The third Rozen Maiden doll, and Souseiseki's older twin. She and Souseiseki are both referred to as "gardeners" for their ability to communicate and tend not only to regular plants, but also to the "soul trees" of humans.

Despite her attitude towards Jun, Suiseiseki does care a great deal for him, and her attempts to cover that up usually manifest in the form of more insults. In fact, she cares deeply for everyone in her life, even if she does not show it outwardly. In Rozen Maiden träumend, Suiseiseki stands out among the dolls in that she values her sisters' love more than the goal of becoming Alice. She is one of the few dolls who opposes the Alice Game, and has no intentions of becoming Alice if it means taking her fellow sisters' Rosa Mystica. Suiseiseki and Jun attempt, without much success, to convince the other Rozen Maidens that the Alice Game is a meaningless endeavor. In her brief appearance in the OVA, she makes the same appeal to her twin several times.

In the anime, Suiseiseki's first impression is different than that of the manga. She appears very shy and nervous, and is very distrustful of humans because one had kidnapped Souseiseki. Shinku once described Suiseiseki as being the most shy and timid of the Rozen Maidens.

Suiseiseki tries to avoid participating in the Alice Game as much as possible, but she can use her watering can to make plants emerge from the ground and manipulate them. Her artificial spirit is named after the popular Anna Sui perfume. Suiseiseki was also the winner of the Anime Saimoe Tournament in 2006.

In the Rozen Maiden träumend, after Jun become her medium. She is jealous of Shinku that Jun always stay with her alone. That means she also loves Jun.

In the next-to-last episode of Rozen Maiden träumend, Suiseiseki attempts to protect Kanaria from Barasuishou's crystal stakes, and is crystallized for her trouble and her Rosa Mystica seized. Suiseiseki was revived by Rozen in the träumend finale and is last seen watching "Detective Kun Kun" along with Nori and the lifeless forms of Souseiseki and Hinaichigo.

In the latest chapter of the manga, Suiseiseki makes a return to the story as she travels to the alternate dimension where Shinku and Suigintou currently reside. Knowing that Kirakishou now has Souseiseki's body, Suiseiseki intends to protect Kirakishou from being destroyed, much to Shinku's and Suigintou's dismays. She has also actively (and somewhat forcibly) make Jun form a contract with her. However, she was actually making him form a contract using Souseiseki's ring, so that Souseiseki may be revived. Suiseiseki is a very prominent and popular character in the series
