Sachiko Shinozaki (篠崎 サチコ Shinozaki Sachiko?) is the antagonist of the fan game.


Sachiko is a girl of normal stature for a young child, with long black hair and bangs that cover her face. She wears a tattered red dress. When she is appeased, her outfit changes. Her hair becomes shorter, so you can see more of her face, revealing her black eyes. She wears an off white colored dress.


While she was alive, Sachiko seemed to be rather shy and recluse. She did not have any friends and she didn't spend her time socialising too much. She loved her mother dearly and her death enraged Sachiko, because of which she became a vengeful spirit. As a spirit she is sinister and murderous. Killing and torturing people, both physically and mentally, is a source of fun and joy for her. Sometimes she plays with her victims, pretending to help them or be their friend, just to kill them afterwards. She is usually accompanied by Yoshikazu Yanagihori, who brings and traps the victims for her. She first started trapping children in the school to please her mother, but eventually it became solely a source of amusement.
