A full body shot from a side view of a female version of Kamen Rider X, known as Kamen Rider XX, gliding gracefully with arms spread wide across the deep ocean floor where faint shafts of light pierce the water. She has a feminine curved physique with medium breasts and a slender waist, encased in a medium-grey bodysuit. Her metallic silver helmet features rounded crimson visors for eyes, a black V-shaped antenna extending from the brow, and a matte black mouth area. A black stand collar integrates with thin protectors over her collarbones, extending under the arms to the solar plexus. On her chest, a wide, thin, hard crimson X-shaped protector fits tightly to her curves, with the intersection dipping at the cleavage. A smaller crimson X-shaped protector is layered over a thin black protector at her solar plexus. She wears black shoulder armor with small, red-glowing "XX" engravings, black long gloves, and a deep V-shaped black protector over her lower abdomen and crotch. At her hips, two lemon-yellow vertical mechanical cylinders are fixed in black holders on each side. Her legs are covered in the medium-grey bodysuit, with black mechanical knee protectors and tall, mechanical black high-heel boots. The scene is an ethereal underwater abyss with drifting particles and a serene, mysterious atmosphere.
