Kaoru Rokujouji appears in the "Black Jack" anime series. She is a woman with a bald head and black eyes. Married to Rokujouji, who ignores her completely and focuses his attentions on another woman he calls a princess and wishes to marry, Kaoru burns with seething envy toward this rival. Consumed by jealousy, she believes eliminating the princess is the key to reclaiming her husband's affection and favor. Despite this driving motivation, her attempts to kill the princess have repeatedly failed. Her story centers on this persistent vendetta, defined by her role as a spurned spouse.
