Kazuki Kazami (風見一姫, Kazami Kazuki) is Yuuji Kazami's elder sister who disappeared in an accident when Yuuji was ten years old.
Hailed as a genius from everyone around her at a very young age, Kazuki is a very logical, rational, and calculating person; however she has a shown a lighter side of herself from time to time, as she frequently liked to toy with Amane. She harbors a very strong affection for her brother, Yuuji; taking on the role of his protector.
Kazuki was involved in the minibus accident of 2005, which was when and where she met Suou Amane. Roughly two weeks after the accident, Kazuki gave Amane the chance to flee and find help, while she remained behind. Kazuki was one of the last two survivors of the incident, besides Amane, along with Yoshihiko Ochi. Shortly after Ochi passed away from malnutrition, Kazuki and the deceased victims of the crash were found by government agents. Kazuki was saved by the agents, and brought to Ichigaya headquarters, where she would become part of their "Thanatos System".
