According to an ancient legend, mermaid's flesh can grant immortality if eaten. 500 years ago, Yuta unknowingly ate a piece of mermaid's flesh. For centuries, he travels across Japan, hoping to find a mermaid, thinking she may be able to make him a normal human again. When he finally finds one, he discovers that she and her companions have been raising a girl to be their food so they can eat her and take on her youthful looks. That is how mermaids stay young. Yuta kills the mermaids and rescues her, but she has already eaten some of the mermaid's flesh. Although he had to kill the mermaids, Yuta isn't too disappointed. Yuta's once lonely existence is now over, as he has found a companion in Mana. And Mana, who had been trapped in a small hut her whole life, finds delight in even the simplest of things. Together, Yuta and Mana attempt to seek out more mermaids, trying to become normal humans again.

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.
