A family suicide occurred in the suburbs of Gunma Prefecture (we'll call this family the Suzukis just for convenience). A few months later, they decided to pull down the house in which the family used to live. A group of university students in Tokyo, calling themselves "The Paranormal Research Group," heard about this and decided to visit the house before it was gone. The group consisted of two boys and two girls.
When the group arrived, the house was already in the process of demolition. Inside was a total mess. They went in with a video camera on hand and started exploring. "Hello, Mr. and Mrs. Suzuki! Please excuse us!" Laughing and joking, they shouted in the empty house. "Is this your kitchen?" "May I use your bathroom?"
After some time, while the rest of the group were having fun, one of the girls began to feel scared so they decided to call it a day. "Goodbye, thank you for having us!" They shouted as they left. They stopped the video camera and got into the car. On the way home, the other girl said, "Look! I found this ring in the house. We should keep it in our club room as a memento."
The next day, the group got together in one of the boys' room to watch the video.
"Hello, Mr. and Mrs. Suzuki! Please excuse us!"
They froze. An unfamiliar voice, which they did not hear at the time they were in the house, was recorded in the tape.
"Is this your kitchen?"
"May I use your bathroom?"
"Goodbye, thank you for having us!"
Everyone fell silent...then, suddenly, their mobiles started ringing all at the same time. They were all very alarmed, but managed to calm down and picked up their phones.
All that the two boys and the timid girl got was silence...but the girl who snatched the ring heard something.
".....Hi, this is Suzuki. May I please have my ring back?"
