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.
Sachiko often looks sad and alone when seen wandering the haunted school.
But the students or kids taken there, don't know that she is the one who brought them here.
