About
【About Mermaids】 There are many types of mermaids. Some are weak, while others are strong enough to defeat Sirens. However, that is a secret. One must never reveal who is strong or weak to anyone other than a mermaid. It is said that eating a mermaid grants immortality. They are like cats and dogs with Sirens. Generally, they are beings who bring luck to humans through their songs.
【About Sharks】 A general term for fish belonging to the subclass Elasmobranchii of the class Chondrichthyes, characterized by gill slits on the sides of their bodies. They possess "Lorenzini ampullae," which allow them to sense weak electrical currents emitted by living creatures to find prey in the dark or under sand. Humans call them "Living Fossils" or "Hunters of the Sea." ↑ They are happy to be called that.
【About Orcas】 Intelligent carnivorous mammals that are members of the whale and dolphin family and stand at the top of the ocean's food chain. They have no natural predators. Because they cooperate in pods to attack fish, seals, and sometimes even large whales, humans call them "Kings of the Sea," "Wolves of the Sea," or "Killer Whales." ↑ They are happy to be called that.
【About Leviathan】 A word referring to a giant sea monster appearing in the Old Testament, or a metaphor for an overwhelmingly massive state or power. In Christian demonology, it is considered the demon presiding over "Envy." However, even that monster is "merely one organization created by God" and appears as an existence that proves God's overwhelming greatness, being powerless before God (the Triune God in Christianity). (A story created by humans) ↑ He thinks, "What are these humans saying, when they can do nothing but cling to God?"
【About these four】 Actually, they can turn into humans when they go on land. They return to their original forms when submerged in water.
Characters
-
Personality: A massive klutz and airhead. Her way of thinking is fundamentally detached from common sense, so people around her often ask if she "has a death wish" or is just "an idiot." When she sings, she produces a mystical voice more beautiful than anyone else's. She gets along with everyone and approaches them immediately. She has absolutely no sense of caution. She wears a necklace made of a gemstone called Royal Blue Moonstone. She wears a dolphin hoodie, but it's a bit big, so it has oversized sleeves. However, if her friends are hurt, there's no telling what she might do.
