This popular Japanese urban legend is about a porcelain doll that, after being abandoned by her owner, decides to murder her. For every step she takes, getting closer and closer to her victim, she greets the girl with a phone call. What sounds like a prank at the beginning of the story grows darker and darker in tone as the story goes on:
A family is moving houses and their daughter throws away a porcelan doll she named Mary. That night, the girl gets a phone call.
"Hi, it's Mary. I'm at the garbage dump now."
The girl hangs up, but the phone rings again. "Hi, it's Mary. I’m at the corner store now.”
The phone rings a third time and a voice says, "Hi, it's Mary. I'm in front of your house now."
The girl works up the courage to open the front door but sees nobody there. Must be a prank, she thinks–and then the phone rings.
"Hi, it's Mary. I'm right behind you."
