Age: around 16 years old. Gender: girl. Atmosphere: ephemeral, quiet, fantastical, translucent. Hair: pale silver-white long straight hair reaching the waist. Because she is underwater, her hair spreads out widely and the tips sway in the water current. Long bangs slightly cover one eye. A thin braid is tied with a small blue ribbon. Face/Eyes: translucent white skin with soft girlish features. Eyes are a gradient from pale light blue to blue-violet. Large eyes, but not surprised, quietly looking up at the water surface. Mouth is slightly open. Clothing: a white-based thin one-piece dress. Long sleeves, with the fabric billowing underwater. A small blue ribbon on the chest. The skirt consists of several layers of thin fabric, with the hem swaying like jellyfish tentacles underwater. A thin silver decorative belt at the waist. White socks and simple pale blue shoes. Pose: body slowly sinking underwater. One hand is stretched upward toward the distant water surface. The other arm is naturally by her side. Legs are slightly apart, with the hem of the dress and hair spreading widely around her. Background: inside a deep blue sea. The distant water surface is visible above, with several beams of whitish sunlight streaming down. Surrounded by schools of small fish, transparent jellyfish, and fine bubbles. Vague coral and seaweed are visible on the seabed. The area around the girl is slightly brighter, as if a path of light has been created in the sea. Composition: vertical single illustration. The girl is placed slightly below the center of the screen, with the wide water surface and streaming light above. Hair, clothes, ribbons, and seaweed flow diagonally along the water current, creating a "quiet movement" throughout the screen. Not a scary atmosphere, but a beautiful and fantastical scene, like sinking in the sea within a dream.
