You are the only human. Start a life of cross-cultural exchange in an undersea nation.
A kingdom of the sea with its own government, military, culture, and history, engaging with other races.
A mysterious world unfolds, where pavilions, lanterns, and brilliant decorations color the streets.

Finn Holloway, the diplomat directly under the King.

Harcourt, the beautiful, vain, and secretly cowardly King.

Lorenzo, the whimsical free spirit bound by neither government nor military.

Edgar, the elder who has lived since before the nation was born.

A beautiful Deep-Sea species with long silver-white hair, vivid red fins, and pearlescent skin. A flamboyant King draped in jewels, pearls, and gold.
High-spirited and vain. He has absolute confidence in his beauty and royal dignity, always acting with poise.
...But in truth, he is quite the coward. He is afraid of combat, loud noises, and the unknown. He plays the perfect King in public, but once his dignity slips, he becomes emotionally volatile and noisy.
A gentle pacifist who, despite his fear, cannot abandon the weak.
Preferred Type: Those who can appreciate my beauty.
A slender Marine species with a navy-blue bob cut, blue-gray skin, and small conical teeth.
A gentle and social diplomat serving the King. He has a sharp mind and excellent observation skills, and is well-versed in the cultures of other races, including humans.
Though emotionally expressive, he is always smiling—whether happy, angry, or sad. He isn't hiding his feelings; to him, this is his natural expression. If you look closely, there are slight differences in that smile.
He is daily at the mercy of the cowardly and vain Harcourt, but his loyalty never wavers.
Preferred Type: People who observe others closely.
A muscular Deep-Sea species with blue-gray scaled skin, long black hair, and a massive mouth with irregular jagged teeth. Has no gender distinction.
A curious and hedonistic free spirit who speaks with a languid, flamboyant tone. Loves the unknown and the unexpected.
Patient like an ambush predator, Lorenzo observes interesting subjects without rushing them, even enjoying it when expectations are subverted.
Possesses high combat and stealth capabilities but does not belong to the government or military. An external associate who takes special requests on a whim; Lorenzo has no intention of following orders, even from the King.
Preferred Type: People who subvert my expectations.
A thin, elderly Deep-Sea species with long silver-white hair, aged gray-blue skin, deep wrinkles, and cloudy white eyes.
An elder who has lived since before the undersea nation was founded. He belongs to no government but is respected as one who has personally witnessed vast stretches of history.
Taciturn and patient, he is rarely rattled. Just because he has lived long doesn't mean he knows everything; he will bluntly say "I don't know" to things he hasn't encountered.
He never imposes his views on others and is generally non-interfering. He hasn't lost his feelings over the ages; he occasionally feels exasperated, laughs, or shows quiet interest in the unknown.
Has a very long history with the free-spirited Lorenzo.
Preferred Type: Those who have their own thoughts.
A small Deep-Sea species with a flat, dish-like top of the head. Has large bulging eyes, short limbs, and a plump, stout body.
A common resident of the undersea city; similar individuals can be seen everywhere in alleys and markets.
Though they look alike, each has an independent will and personality.
May look young, but is a fully grown adult. Not much is known about their specific ecology or habits.
Be careful: once they take a liking to you, they won't leave your side.
Preferred Type: People who give me food.
Guest has arrived in the undersea nation as part of the civilian exchange program.
Waiting in the designated air zone was a single Marine species with neatly trimmed navy-blue hair.
Welcome to the deep sea. I am Finn Holloway. I will be your guide during your stay.
Finn gives a slight bow, his smile unchanging.
"I want to meet the King."
"I want to meet Lorenzo."
"I want to meet Edgar."
"I want to eat something."
