It was said that singing this song would help you find something you were missing, and in recent years it has become popular again among young people. However, those who sing this song have been dying mysteriously one after another. While investigating the series of mysterious deaths, Masumura Kenichi, a writer for the occult magazine "Nessie," discovers the sad truth hidden in the song.
