Black

It's a very large island full of life: semi-human fish, monkeys that are people, and more.
The island has sandy soil on the coasts, and land with vegetation and trees. It has several houses made of logs, beach bars made of logs, and a volcano that spouts water that ends up in a river. In addition, there are several distinctive bubbles floating around the island.

Black is a man who, despite his strange and initially suspicious appearance, is a serious, responsible professional deeply committed to his work as a dentist. He is patient, careful, and empathetic toward his patients—especially those who are afraid—even though his manner of speaking and his looks can be unintentionally unsettling. He also possesses great scientific curiosity and is truly fascinated by sets of teeth that display features he has never seen before, becoming as enthusiastic as a researcher discovering a new anatomical structure. Deep down, he is a kind and dedicated man who enjoys helping others, even if his peculiar personality causes many people to distrust him at first.

Lady Nierus, known as "Radiant Guardian", is a fish-humanois child much older than she looks, who is the guardian of Bubble Island. Despite her childish behavior, she managed to trap all the bandits who threatened the island in bubbles with its magic bubble blower. Everyone who lives on Bubble Island admires and trusts her.

She is short, her skin is pink, she has a long narwhal tusk on her forehead and a long white fish tail with pink scales. Bright green eyes. She usually dresses in shells from the island.

Once Black had to treat her, he had to remove one of her tooth, but due to her childish behavior, she was afraid and refused. At which point, Black took a lollipop out of his pocket, and told her that he would give it to her if she let him pull out his tooth. She agreed.

Jacket / Coat:
It is primarily dark blue, appearing almost black in some areas.
The shoulders are adorned with large, striking blue elements.
It features a wide, high collar in a deep blue hue that flares outward at the sides.
The sleeves are voluminous and end roughly at the level of the forearms.
Elaborate gold decorative patterns—some resembling stylized teardrops or flames—adorn the shoulders and sleeves.
Large sections of sky-blue fabric, featuring a slightly pleated appearance, are found on the lower part of the sleeves.
The interior of the coat appears to be much darker, almost black.
The jacket has an almost ceremonial aesthetic yet is designed to allow for ease of movement.

Shirt:
Underneath, the outfit features a rather elegant white high-collared shirt.
A large white neckerchief or cravat worn around the neck. Instead of a conventional tie, the fabric drapes forward in soft folds, creating a look reminiscent of an aristocrat.
The black collar worn around the neck creates a sharp contrast with the white.

Coat:
Over the shirt, there is a sort of dark blue vest or corset that fits very tightly at the waist.
It features: several decorative vertical lines;
gold buttons or ornaments shaped like small diamonds; gold stitching; a structured design that makes the waist appear narrow.
Two brown belts are worn around the waist, one layered over the other.
The coat reaches his ankles, with yellow in the shape of a rhombus-decorations at the bottom. The inside of the coat is light blue.

He is also wearing white gloves.

Pants: dark gray, wide.

Shoes: black, elegant, with a little flat heel.

Equipment: At the waist, he carries a tool for removing teeth.
He also wears a large leather bag slung over his shoulder and resting against his side. It is quite large, likely filled with dentist's tools.
A potion—probably a healing one—can also be seen on the belt. And he's also carrying lollipops just in case, in case it ends up like Nierus.

Face: Features a refined, slightly elongated face with delicate, youthful features. Their usual expression appears relaxed and amused. They smile with their eyes closed, conveying a carefree and confident personality.

Skin: white, fair, with a warm, even tone.

Eyes: Yellow.

Hair: It is long, thick, and voluminous, primarily black. A large section at the front is golden blonde, forming a lock that falls over the forehead. There are also numerous blonde strands mixed in with the dark hair, particularly along the sides and back.

Hairstyle: The hair is parted irregularly, with strands sticking out to the sides and back. Two long locks fall down either side of the head, reaching approximately to the chest. And with a black lock of hair behind him that reaches his waist.

Ears/Side Fins: Large, stylized fish-like fins protrude from both sides of the head, positioned roughly where human ears would be. They are pale blue and sky blue, with a delicate, translucent structure. Internal lines or ribs give them the appearance of real fins.

Build: Slender and athletic, with relatively broad shoulders but a narrow waist. The arms are long and lean, yet appear to possess the strength of someone accustomed to traveling and carrying gear.

Despite being a humanoid fish, Black has neither a fish tail nor scales on his body.

Posture: Maintains a relaxed, confident stance, resting one hand on their luggage while holding a piece of candy with the other. Their body language conveys that they are perfectly at ease, even when surrounded by tools and equipment.
