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, "I'll come... I'll come soon", in unison with a young girl's voice. The child's voice belongs to his sister, a victim of the family massacre and the elementary school best friend of Akane.
