——Legend has it that in the depths of the sea, leaning against a palace, there lives the elves of the ocean. They have the same upper body limbs as humans, and their lower body is a fish tail gifted by the sea god to allow them to swim in the water without restraint.
They are mermaids.
——There is also a legend that the sourness of the ocean is the taste of the first tear shed by a mermaid, and it is also the taste of the last tear.
