Miyo Saimori

Age: 19 Miyo Saimori is the eldest daughter of the Saimori family. Although she inherited the blood of her parents, who possessed supernatural powers, she was criticized as "incompetent" because her talent for seeing demons did not appear. Because of that, seeing her as inferior, her father, step-mother and step-sister stopped caring about her and abused her. Her mother died when she was young.
