Ningyo no Kizu

Legend has it that when you eat the flesh of a mermaid, you would live forever.

Yuuta and Mana are living proof of this.

. Together, they journey to various places trying to find meaning for their existence, or perhaps even a "cure" for their situation.

One day, they meet Masato, a little boy who seems terrified of his mother Misa. It seems to Yuuta and Mana that mother and son have a very unusual relationship.

What happens when Yuuta and Mana decide to discover the dark secret Masato and Misa are hiding?

And what about those monster-like creatures that have been appearing?
