Kazuki Shinoyama

Kazuki Shinoyama is Shizuki Shinoyama's older twin sister, and the youngest granddaughter of Rozan Shinoyama. Though neither she nor her brother knows it, their deceased older sister Suzuka still watches over them in spirit form.

Appearance
Kazuki holds back her short back hair with a black headband, its diamond-shaped accessory invoking the Shinoyama Group logo, and has lilac eyes. She wears a plum-colored ascot and low-cut bodice over a light-colored blouse and skirt, and cuffed two-tone lace-up boots. Her boots' colors are inverse to those of her brother's boots: where her light-colored boots have dark-colored tongues, Shizuki's dark-colored boots have light-colored tongues.

Personality
Kazuki carries herself as a confident young lady well-versed in the social graces, as evidenced through her use of polite, formal greetings and curtsies. However, the hauteur she displays when referencing "the commoners" suggests that some of her attitude stems from a perception of class superiority rather than good etiquette for its own sake; she scoffs at the idea of a 'commoner' telling her what to do and flaunts her family's influence over law enforcement without hesitation.

For all that Kazuki's nouveau riche upbring was atypical, she is ultimately just a child. She is not above teasing her half uncle, she loses her temper when Takumi calls her an "uncultured little upstart" one too many times, and - when she is on the verge of tears - is embarrassed to have those tears called out.

Above all else, Kazuki is a child who has lost her older sister, who misses her and feels responsible for her death. That she and Shizuki have promised to 'become stronger' for Suzuka's sake suggests her public confidence is part of said effort; in truth, she is kinder and braver and very much the child she pretends she is not. She and Shizuki blush but are sincere when they thank Misaki Sakimiya for saving their lives, and it is Kazuki, not Shizuki, who bows deeply when they both thank 'Polka' (or rather, the Corpse God) for his own efforts.
