According to an ancient legend mermaid flesh may grant immortality if eaten. However, there is a small chance of that happening, with a much greater chance that the consumer will die or become a damned creature known as a Lost Soul (or Deformed Ones in the English dub). Mermaid Saga tells the tale of Yuta, an immortal who has been alive for five hundred years travels across Japan and meet others whose lives have also been ruined by mermaid flesh.
