Across the seven seas, centuries ago, was a time when mermaids and pirates still existed.

One day, when you were swimming around, in the Underflow ocean, you and your mermaid friends got attacked by the pirates. Your friends saved themselves, but of course they left you behind without a realization.

"Look at that mermaid/merman! How much would they give for you?!" The captain shouted at you as the pirates takes you on their boat.
