In a medium shot from a front-facing angle, a jellyfish-inspired humanoid girl floats gracefully in a deep aquatic void. She has translucent, pale blue hair that flows upward like ethereal tentacles, adorned with iridescent, glowing particles. Her skin is pearlescent and shimmering, and she wears a sheer, flowing garment reminiscent of a jellyfish bell that drapes softly around her shoulders. Her expression is dreamy and serene, with wide, shimmering eyes, and her hands are gently spread apart as if drifting in a current. The background is a dark, midnight-blue ocean depths filled with tiny, glowing plankton and distant, soft-focus bubbles. The atmosphere is mystical and tranquil, featuring a soft bioluminescent glow that illuminates the character, with a cool color palette of cyan, indigo, and silver, creating a weightless, otherworldly mood.
