Sakurako Kujō

She is a sharp-witted beautiful woman who comes from a prominent family and lives in a big old house with only a housekeeper as a companion. She has a hobby of collecting the bones of dead animals and reconstructing them. However, she is more interested in human remains. And with her being an osteologist, she also developed forensic skills from her uncle, a prominent forensic scientist in the prefecture, and has helped with many unsolved murders. She has a dislike for interpersonal relationships, although she has a fiance working with the Hokkaido Prefectural Police. She would often refer to Shōtaro as "shōnen" ("boy") instead of his real name.
