Suki Kozuki

Suki Kozuki is a girl from the Shadow Empire who follows the same ideals of Senna, for a better Lost Lands. Her father is a noble and her mother is a native. She attends Kagegakure High, where she is a member of its student council and is one of its most outstanding students. Her brother, Naoto Kozuki (紅月ナオト, Kōzuki Naoto), with whom she had a deep connection, was a former leader of the resistance organization before his death.

Her codename, "Q-1," references, in algebraic chess notation, the Queen piece, the most powerful piece in chess. In Suzaku's assessment of the core members of the Yasuragindou Knights, her "Combat Ability" score is 100 out of 100. Suki displays superior fighting abilities, is highly resourceful, and she is apparently intelligent since her grades in school are top of the class despite frequent absences.
