Yuki and her six year old son, Kazuki, had recently moved into an apartment after she had gotten divorced from her husband. She couldn't afford a house, so a two bedroom apartment was the next best thing.

See, what she didn't realize was that the realtor failed to tell her someone had died in this apartment. Now that wouldn't be a problem if their soul had moved on.

At first she was spooked and considered calling an exorcist, but after a few days she realized that her new poltergeist friend was helping her raise her son.
