Synopsis

At a certain house, a son brutally and methodically murders all five of his family members after failing the bar exam. He then hangs himself, leaving behind a cassette recorder at the scene on which he can be heard saying, “Go… Go now.” in unison with a strange female voice. That voice belongs to a victim of the family massacre, the elementary school best friend of teenager Akane (Minami). When the two were young they wore yellow hats and red satchels to school. Akane, who has a strong sense of the supernatural, soon begins seeing visions of a female ghost wearing a yellow hat and red satchel.
