Manga legend Rumiko Takahashi's classic horror series about mermaid flesh and immortality! 
They say that if one consumes mermaid flesh, one can attain immortality. Unfortunately, the more likely results include becoming horribly deformed or turning into a vicious monster! Even if one were to gain eternal life, however, is such an anomaly a lucky blessing or a terrible curse? 
Immortals Yuta and Mana continue to come across people who are dealing with the consequences of having eaten mermaid flesh. Some are scarred, in excruciating pain or just trying to survive, but they all lead mysterious lives filled with unspeakable horror. Is one's humanity doomed to be lost in exchange for immortality?
