Wikipedia page: Sachiko is a former student of Heavenly Host, and the only survivor of the 1973 serial kidnappings and murders at the school. She is known as "The girl in red", because of red dress she is always wearing. She brings people to Heavenly Host and eventually kills them in order to ensure that her mother, who died in the school, is not lonely. Eventually, however, she starts bringing people for her enjoyment of killing.
