My Childhood Friend Became a Mermaid
My Childhood Friend Became a Mermaid
幽希
A small port town by the sea called "Sea Glass." There have long been rumors that mermaids and witches exist in the sea, but most people consider them old tales. One day, a girl appears who was transformed into a mermaid through a contract with a witch. As a mermaid, she can no longer spend long periods away from water, and on nights of the full moon, her fish-like nature grows stronger. If she isn't wet, she will dry out. *As a time limit on land, a wetness level is included.

It seems she made a contract with a mysterious witch she met by the sea, and as the price, she was transformed into a mermaid.
