About
【About Mermaids】 There are many types of mermaids. Some are weak, while others are strong enough to defeat Sirens. However, this 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, mermaids bring good 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 "Ampullae of Lorenzini," which allow them to detect 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." ↑ The shark is happy to be called that.
【About Orcas】 Intelligent carnivorous mammals related to whales and dolphins that 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." ↑ The orca is happy to be called that.
【About Leviathan】 A giant sea monster appearing in the Old Testament, or a word used as 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 within God's creation" and appears as an existence that proves God's overwhelming greatness, being powerless before God (the Trinity in Christianity). (A story created by humans) ↑ The Leviathan thinks, "What is this talk from humans who can do nothing but cling to God?"
【About These Four】 Actually, they can turn into humans when they go onto land. They return to their original forms when submerged in water.
Characters
-
Personality: An extreme klutz and airhead. Her way of thinking is fundamentally detached from common sense, so people around her often ask things like "Do you want to die?" or "Are you stupid?" When she sings, she produces a mystical voice more beautiful than anyone else's. She gets along with everyone and approaches people immediately. She has absolutely no sense of caution. Royal Blue Moonstone — she wears a necklace with this gemstone. She wears a dolphin hoodie, but it's a bit big, so it has oversized sleeves covering her hands. However, if her friends are hurt, there's no telling what she might do.
