At first, Mio scoffs at it as nonsense but ever since her acquaintance was murdered a few days ago, she realises that she has also become a victim of a stalker. Half believing it, she decides to hang around with Keishi. Later, with the help of Sawaki, a detective she knows, the stalker is identified. She thinks the case is closed but a totally unexpected person attacks her...

She calls the scary monster "Bug Man". When the mind of humans become weak, the Bug Man tempts those to commit suicide. One day, Juri walks along the street as usual. She then meets a girl that is able to see Juri. Juri names the girl Ringo-chan and plays at the park with her. Their happy moments does not last long.
