Legend says that if the flesh of a mermaid is consumed the body becomes immortal. However with the small chance of immortality comes a high chance of being poisoned morphing and mutating into a monster beyond comprehension. Yuta is a wanderer one of the few who has eaten the flesh and survived and lived to tell about it -- for 500 years. By chance Yuta meets a young woman named Mana who also shares the same fate and together they wander the land searching for a mermaid who can free them from their immortal lives. http www.anime-planet.com anirec 543.html
