onineko, a slightly high-angle full-body shot of a young girl floating weightlessly inside a sunken underwater marble sanctuary, gazing upward with luminous aquamarine eyes and softly parted lips. Her floor-length pastel cyan hair spreads outward in the water, adorned with pearl hairpins and delicate coral ornaments. She wears a flowing translucent seafoam-green silk dress with iridescent ruffled layers, silver waist chains, and bare feet encircled by pearl anklets. One hand reaches gently toward a glowing translucent jellyfish while schools of tiny luminescent fish, rising air bubbles, and shimmering caustic sunbeams pierce the deep sapphire-blue water around her.
