High-quality, high-definition animation-style single image set in a freezing ice exhibition space inspired by the "Ice Aquarium" in Kesennuma, Miyagi Prefecture. A fantastical indoor facility where the entire space is composed of highly transparent giant ice, including walls, ceilings, exhibition structures,pillars, and surrounding decorations. The atmosphere is freezing, feeling like minus 20 degrees Celsius, with clear cold air, thin white cold mist, fine ice crystals,frost, frozen surfaces, and microscopic ice particles drifting. It is clearly a frozen ice exhibition space, not underwater.
In the center of the screen, a narrow pedestrian walkway extends straight from the foreground to the background with strong one-point perspective and deep depth. The floor is dry and cold blue-gray, faintly illuminated by pale blue light reflected from the surrounding ice. Huge transparent ice walls tower on both sides, forming an ice corridor. The ice is not completely colorless but has pale light blue, bluish-white, and cyan blue tints, with complex cracks, thin fissures, ice layers,bubbles, crystalline structures, and light refraction visible inside. Frozen frost and fine ice crystals are on the surface.
Crucially, inside the giant transparent ice walls on both sides, a large number of fish are completely frozen and sealed. The fish are not swimming but are stationary as if time has stopped, with their outlines,scales,fins,eyes, and tails clearly visible through the ice. Various marine life from the Sanriku and Kesennuma seas, such as bonito, Pacific saury, rockfish, and common octopus, are frozen in different orientations and sizes. Pale blue light penetrates the fish's bodies, making them appear to glow faintly through the ice.
The ceiling is also covered in giant transparent ice with numerous frozen fish, creating an illusion that fish are swimming in the air. Long, thin artificial lights on the ceiling emit cold white light, enhancing the perspective and reflecting cyan blue onto the walls and floor. Some metal frames, lighting fixtures, and support structures are partially visible behind the ice, indicating a managed tourist facility. Blue illumination and projection mapping cast pale blue and cyan patterns onto the ice surfaces.
Niiyama Satomi is positioned in the corridor, not completely blocking the central axis, shown in a medium to medium-long shot showing her full body to emphasize the scale of the ice aquarium. She is wearing a large, pure white hooded winter bench coat over her private clothes, with the volume of the coat and soft wrinkles of the padding detailed. She is gently adjusting the front zipper with her right hand, wearing a bright, radiant, and happy smile, looking slightly shy due to the freezing cold, with a pure and elegant demeanor.
She has large, almond-shaped eyes that are wide horizontally, a gentle droopy eye shape with clearly visible lower eyelids, and soft, natural eyebrows. Her expression is peaceful and quiet as she gazes at the frozen fish. Pale blue rim light and cyan reflections from the ice environment illuminate her hair,skin, and clothes, blending her naturally into the cold atmosphere.
