Suigintou is the first Rozen Maiden doll. Her desire to win the Alice Game is the strongest of all the dolls, and is primarily driven because she wants the attention of their "Father", the dollmaker Rozen. Initially, Suigintou's will to exist was so strong that she was able to move even without a Rosa Mystica. She could also use her powers without a medium. Sadistic, spiteful, and arrogant (all due to her Inferiority complex), she would stop at nothing to become Alice. Although she avoids talking with her sisters, she has a particularly bitter hatred for Shinku.

However, when she meets her medium Megu, Suigintou's attitude begins to shift; and she feels connected to Megu. Suigintou later wants to collect the Rosa Mystica to heal Megu's heart ailment instead rather than just become Alice. However, Suigintou fails in this endeavor, when she discovers that she used up Megu's energy.
