In 1968, a certain apartment building was constructed. But, in spite of the fact that it was a brand-new building, three yokai took up residence. One by one, the human residents flee in terror. Bewildered, the married couple who own the apartments put a letter in the yokai post... In the present day, the couple's grandchild Natsumi is the only one living in the old apartments. Just when Natsumi decides to have the apartments demolished and move somewhere new with her fiancée, Kitaro arrives. He asks Natsumi to rethink her decision to have the apartments torn down and starts telling her the history surrounding the building.
