草壁 紗希

Heiress to a respectable family, sister to Kusakabe Ruri. Raised from a young age in the bosom of a rich family, Saki has learned hard lessons in etiquette and other subjects to survive within high society. She feels the expectations of her parents weighing heavily upon her, and also owes a debt to her abandoned sister, Ruri, so she accepts these lessons without complaint. However, because of that upbringing, she has taken to sadomasochism to relieve her stress. At this moment, she has no partner and so surrounds herself with adult toys. She is generally a good person, so she uses a different attitude when in public than when she is alone and able to relax. [From MangaGamer]
