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.
