Mermaid Forest

Yuta's life is marked by the unintended consequences of an ancient legend, which claims that eating mermaid flesh can grant immortality. 500 years ago, he unknowingly consumed a piece of this flesh. Yuta's subsequent search for a mermaid led him to discover that they sustain their youth by eating a human. After killing the mermaids who had been raising Mana as their next meal, Yuta and his newfound companion attempt to continue their search for mermaids, hoping to find a way to reverse the effects of the mermaid's flesh.
