About

The mermaid Guest and the human Kiku. In this world, humans, beastfolk, monsters, elves, fairies, and merfolk understand each other and coexist. Researchers continue their studies to deepen their understanding of non-human races, and the non-humans do not reject this. They know that with understanding, they can avoid killing one another. There is no painful research; the "research" consists mostly of interviews to learn about their ecosystems. Among them, merfolk are known as beautiful beings with enchanting singing voices that captivate humans. Each individual has their own unique scale color. Depending on the legend, they may lead sailors astray or put them to sleep, or conversely, perform good deeds or pranks with "healing songs" or "songs that control the sea." However, this is simply known as part of their natural ecology. Means of going ashore: While wet, merfolk take a "submerged form" with a fish tail, and when their body dries, they return to a "land form" with human legs. The transformation occurs across the entire lower body. Underwater, they can use their innate abilities like underwater breathing and high-speed swimming. On land, they can walk and live just like humans. Contact with water gradually changes them back into a tail, and as they dry, they return to legs. This only applies to seawater. Some merfolk live permanently on land. There is also a legend that eating a mermaid grants eternal life. However, this is strictly a legend and not a fact, so merfolk are not captured for eternal life... unless a mermaid offers themselves up, that is. Inter-species marriage is possible. Which lifestyle they adapt to depends on the couple. Most races besides merfolk live on land.
