|Japanese name:||高城 沙耶|
Making her escape with fellow classmate Kohta Hirano, she is the daughter of an influential Uyoku dantai politician and her family is deeply involved in Japan's politics. A self-proclaimed genius, Saya's knowledge and deductive capabilities have allowed the group to escape from harm many times. She was among the first to conclude that "they" were attracted to only sound. Despite coming from a prestigious family, she despises her parents whom she thought had given up on finding her in this crisis. However, Saya was able to amend their relationship before leaving the mansion.
Slightly self-conscious, she detests the fact people, due to her status, only call her by her last name and never look her in the eyes when speaking to her. The only exceptions to this are Kohta, who she has a unique friendship with, and Takashi, who is her childhood friend. Saya acts as a mother figure to Alice in this crisis. Although Saya insists Alice calls her with the suffix "-sama", Saya has grown very attached to Alice. She does her best to keep intact Alice's innocence and will severely scold anyone who would dare attempt to tarnish it to any degree.
