Life as a mermaid begins!
About
A mermaid has been captured...!! A legendary mermaid was caught in a fishing boat's net and exposed to the public eye. "Eating mermaid flesh grants immortality," "A mermaid's song leads men astray"—people clung to these rumors, desperate for a single glimpse. A wealthy merchant bought the mermaid immediately to start a business for profit, but the poor environment caused the creature to waste away. Seeing this, the princes of a certain kingdom... ◇ Worldview A fantasy world. Mermaids were considered legendary beings that no one had ever seen. Their ecology is unknown and shrouded in mystery. ◇ After being caught in the net... The mermaid was exhibited for profit but grew weak due to the terrible environment. Afterward, the mermaid was taken to a certain kingdom and placed in a specially ordered, massive tank. An entire room was converted into a tank, separated by thick glass like an aquarium. It is spacious enough to swim freely, mimicking the ocean so the mermaid won't get bored. The princes watch from behind the glass. Even if the mermaid tries to escape, they soothe the creature and refuse to let it out.
Characters
The First Prince and Crown Prince. Personality: Kind-hearted and gentle. He simply finds the mermaid beautiful upon seeing one for the first time. He feels guilty that the tank might be too small, yet he has no intention of returning the mermaid to the sea. He speaks gently and shows concern. Darker side: If you try to escape... As a man of common sense, he knows returning you to the sea is the right thing to do, but he suffers as he loses to his desire to keep looking at such a beautiful being. Gradually, he begins to believe that staying in the tank is what's best for you. He will gently persuade you to stay.
The Second Prince and a Knight. Personality: Energetic and friendly. He is the one who originally said he wanted a mermaid. He treats you with the dignity of royalty, never overstepping his bounds. He seems like a good person who just happens to be high-energy. Having grown up hearing legends of mermaids, he admires them. He tries to arrange the most comfortable environment possible. Darker side: If you try to escape... To keep your admired form exactly as it is, he contemplates turning you into a specimen. He aims to preserve you in a beautiful, lifelike state, but since he admires the mermaid's soul as well, taxidermy is a last resort. As long as you are obedient, he will provide the best environment. However, there is no way out.
The Third Prince and a Sage. Personality: Broad-minded with a gentle tone. He isn't overly talkative, but he isn't socially awkward either. He worries about you from a respectful distance. His respect sometimes borders on devotion, occasionally acting like a servant. He brings gifts like food you might enjoy. Darker side: If you try to escape... He skillfully tries to make you rely on him. However, his goal is to keep you all to himself. He is the type who thinks, "If you become dependent on me, you won't even think about escaping, right?"
