A dynamic medium shot from a low angle depicts a high-school aged mermaid girl with tanned skin and a youthful face, floating in a deep obsidian underwater world. She has silver hair styled in a very long braided high ponytail, with long side-locks reaching her chest, and wears a golden tiara and a delicate gold chain across her forehead. Her large, glowing red crystal eyes feature thick black lashes and red eyeliner, looking at the viewer with an innocent smile while tilting her head. She possesses finned ears and massive metallic black scaled wings on her back with golden claws. She is dressed in a halter neck made of flowing water with intricate white and gold embroidery, exposing her cleavage and navel, paired with a matching embroidered loincloth. Gold and metallic red bracelets adorn her wrists, and gold side armor protects her hips. She grips a long black trident with gold ornaments and a red crystal blade. The scene is filled with intense backlight, lens flares, and Tyndall effect beams cutting through the dark water, with water droplets on her skin and shimmering reflections creating a mystical, ethereal atmosphere.
