Cynthia

Cynthia is one of the servants of Ziel, though they are more like friends.

Personality
Cynthia appears to be laid-back and carefree, rarely seen without a smile. She is wise, kind and nurturing who often has advice for her younger kin.

Many conversations show that Cynthia's nature comes from the horrible experiences from her past and lack of maternal love in her life, explaining her overprotective, smothering attitude towards Ziel is because she knows what it is like to be alone, and doesn't want Ziel to ever feel what she felt growing up. This does not mean her fawning is entirely reserved for Ziel alone; she is known to treat the other servants as if they were her children, although at a level that is not intense as the one that she adopts in her treatment of Ziel.

Cynthia adopts a completely different persona when she interacts with others, where she is portrayed as a figure of maturity and elegance.

Cynthia has also been depicted as ruthless and bloodthirsty on the battlefield, deriving disturbing joy from striking down her enemies with wild abandon. While she is not without the capacity to show mercy to her foes, Cynthia usually only does so on the behest of Ziel.

Cynthia is known to enjoy bathing (including hot springs and spa treatments).
