character: shiranami_ramune, Full body shot of Shiranami Ramune, an aqua mermaid duelist, captured in a graceful swimming pose mid-motion in the lower 70% of a vertical composition. She has long multicolored blue and white streaked hair tied in a braid with a heart-shaped hair ornament, and striking red-orange eyes. She is dressed in teal-blue scaled armor with a flowing fin-like skirt and shimmering jewelry, her hands firmly gripping a shimmering trident staff as she glides through the water. The background is an underwater coral dueling field filled with glowing bioluminescent coral formations and schools of light particles resembling bubbles, while the top 30% of the frame consists of empty, clear water. Cool aquatic lighting permeates the scene, creating a serene yet dynamic atmosphere with a deep blue and teal color palette, enhanced by ethereal light rays filtering from above.
