Sayaka Kirasaka is a War Dancer of the Lion King Organization, specializing in hexes and assassination. Her traumatic childhood involved physical abuse by her late father, resulting in severe androphobia. After his death, the Lion King Organization took her in as an orphan and trained her. She has knee-length brown hair tied in a long ponytail with square bangs and turquoise-green eyes. Her typical outfit is a school uniform: a white blouse, miniskirt, thigh-high black socks, white sneakers, and a signature purple sweater-vest. Alternative attire includes a dark red Qipao for formal events, a purple bikini top with a flowered beach dress for extended stays in tropical locations like Blue Elysium, and a Coist Bodrem costume worn during a Halloween festival. Her personality blends fierce loyalty with deep-seated anxiety. She exhibits obsessive protectiveness toward childhood friend and former Lion King Organization roommate, Yukina Himeragi, serving as her confidante. Her androphobia manifests as hostility toward human males, leading to confrontational behavior, disobedience toward male superiors, and avoidance of mobile phones due to discomfort with male voices near her ears. However, she feels no such phobia toward non-human males like vampires. Internally, she shows kindness and gentleness toward trusted individuals, alongside cynicism about her circumstances. In combat, she wields the enchanted weapon Lustrous Scale (Koukarin), which transforms into the bow Der Freischütz. Her capabilities include summoning messenger and surveillance shikigami, executing high-speed movement techniques ("Shinsei"), and projecting concussion waves ("Shinsha"). Her aggressive fighting style reflects confidence, though intense emotions occasionally impair her judgment during battles, like her rooftop assault on Kojou Akatsuki. Her relationship dynamics evolve significantly. Initially hostile toward Kojou, accusing him of defiling Yukina and endangering her, their violent confrontation required external intervention. Forced collaboration during crises, such as rescuing Yukina and Asagi Aiba from Christoph Gardos, gradually shifted her perspective. Kojou's kindness fostered unexpected romantic feelings, leading her to become his second blood partner. Subsequent interactions show reduced aggression toward him, marked by nervousness and blushing. She frequently locks horns in rivalry with fellow War Dancer candidate Shio Hikawa over trivial matters. She distrusts Asagi Aiba, misinterpreting Asagi's interactions with Kojou as threats to Yukina's interests. Princess La Folia Rihavein specifically requests Sayaka as her bodyguard during visits to Japan or Itogami Island. Her character development includes the gradual mitigation of her androphobia. While early seasons emphasize her refusal to cooperate with male authority figures, later interactions show reduced focus on this trait, limited to occasional remarks. Her romantic attachment to Kojou intensifies, including jealousy when witnessing his interactions with other women like La Folia. Being his second blood partner solidifies her role within his circle. In the series' conclusion, she marries Kojou as part of his extended marital group. Trivia notes list her as the tallest among heroines, with measurements of B88-W58-H85. She demonstrates cooking skills during Valentine's Day chocolate sales.
