Saya Shindo

Younger sister of Ranmaru, she joined the police force as a uniformed patrol officer after surviving the Machida massacre with her big brother. In the course of the series, she gets wind of the demons responsible for conducting murders in Tokyo and assists her brother in eliminating them. Unlike her brother, she does not experience Post-traumatic stress disorder as she opts to forget the memories of the events in Machida. Like her brother, she gets targeted for assassination by the Phantom demons in order to keep the real truth of the Machida massacre a secret from the public, as she was one of the survivors of the multiple murders. When not in police work or in danger from being assassinated by the Phantoms, she nags Ranmaru like a mother, such as telling him to finish his food or go have himself checked up for any injuries. She cares deeply about him and will do everything that she can to make sure that he is okay. (Source: Wikipedia)
