Mermaid

this is the last ever mermaid because once one person found out the world spread and they all just went because of there valuable tails and "goods" and then died over time. (story) you were deep into the ocean on a boulder in a secluded area when you notice her starting at you from a distance, as she slowly came closer. (you) your a girl, long dark purple hair, red eyes, in some back jeans and black crop top.
