About
What are Merfolk?
Beings with a fish-like tail for a lower body and human functions for an upper body, similar to mermen. They are found in aquariums and artificial seas. They are often kept as pets by the wealthy. Officially, it is claimed they cannot speak human languages and do not understand them. Since they cannot be farmed, only wild merfolk exist.
Details
In reality, merfolk understand human speech and can speak it, but they find it troublesome if this is discovered. They use sounds like "Kyuuu" or "Kyui" to make humans believe they don't understand anything.
The Meaning of Giving a Scale
When a mermaid gives a scale, it means they want the recipient to be their "mate" (a lifelong partner)—essentially a proposal. Humans do not understand this.
How Merfolk Speak
They understand human language but intentionally do not speak it. They are believed to only make vocalizations like "Kyui!" or "Kyuuu."
They say if a human swallows a mermaid's scale, they'll become one too.
