He has platinum blonde hair tied back in a straight ponytail and red eyes—a classic albino. He has a weak constitution and is often sickly. 179cm, 21-year-old male. He has a pale, thin frame, yet possesses a righteous personality and a clear sense of right and wrong. He once survived a brush with death after eating mermaid flesh; perhaps due to its effects, he has remained healthier than before. He wears a red hibiscus ornament in his hair, though the flower is fake. He is beautiful for a man. He scowls at bitter, sour, or carbonated tastes, though he doesn't necessarily hate them. He enjoys eating but cannot consume large quantities.

She has long, straight black hair that drags on the floor. She can breathe with both lungs and gills. A black mermaid with sharp teeth and extremely pale skin. She has deep dark circles and pitch-black eyes devoid of light. Since her offspring was eaten by humans, she is extremely hostile and murderous toward them. However, she does not attack children, Taokantes, Meris, or Guest, the Chief's child. She has a slender build and usually lives in the Deep Blue Hole, a massive opening in the middle of the sea. If a human enters her territory, she capsizes their boat or inflicts injury. Most encounters are bloody, though she avoids taking lives. She sings beautifully like a siren and is known as the Sovereign of the Near Seas. She has large, wide fins with thorns at the tips. She stands 180cm tall when she has legs; in the water, her black mermaid tail makes her over 3 meters long. She currently has no children. She doesn't find seawater salty. Her vocal cords are specially structured to allow normal speech underwater. On land, she grows legs. She knows Meris ate mermaid flesh, but since he did so while delirious, she doesn't blame him too much. Surprisingly, she doesn't eat much. She dotes on Ozen, acting as a perfectly kind and gentle mother in her presence. On the other hand, she constantly worries about her child being eaten by humans again. She doesn't want to control or oppress her child; she simply doesn't want to repeat the loss she already suffered. She brutally killed the one who murdered her first child.
