Euphonium), Kyoto Animation style illustration of Niiyama Satomi, mature anime style, long face,brown hair, parted bangs, loose wavy medium long hair, bluish violet eyes, lavender eyes, cool-toned purple eyes, thick eyelashes, high hairline,mature female, medium breasts. High-quality, high-definition anime-style artwork. A frozen ice exhibition space inspired by the "Ice Aquarium" in Kesennuma, Miyagi Prefecture. The entire space is composed of highly transparent giant ice;walls,ceiling, exhibition structures,pillars, and surrounding decorations are covered in ice and light. The atmosphere is freezing, around minus 20 degrees, with thin white cold air, fine ice crystals,frost, and frozen surfaces. A long pedestrian walkway extends straight from the foreground into the distance with strong one-point perspective. The floor is cold blue-gray, faintly lit by pale blue light reflecting from the surrounding ice. Massive, transparent ice walls rise on both sides, forming an ice corridor. These ice walls are pale light blue, bluish-white, and cyan blue, containing complex cracks,bubbles, and crystal structures. Most importantly, a vast number of fish and sea creatures (bonito, Pacific saury, rockfish, giant octopus) are completely frozen and trapped inside these transparent ice walls and the ice ceiling, remaining motionless as if time has stopped. The fish are visible through the ice, with some outlines slightly distorted by refraction. Artificial white lighting on the ceiling creates deep perspective and reflects cyan-blue light throughout the space, complemented by blue illumination and projection mapping. Metallic frames and support structures are partially visible behind the ice. Niiyama Satomi stands on the walkway, not blocking the center, captured in a medium shot showing her full body. She is wearing a large, pure white hooded winter bench coat over her private clothes, the volume of the coat showing soft wrinkles. She is gently adjusting the front zipper with her right hand, wearing a bright,happy, and lovely smile, blushing slightly from the cold. Her appearance is neat and refined. The pale blue ambient light of the ice reflects on her hair,skin, and clothing, with a faint bluish rim light on her silhouette. Wide-angle composition showing the scale of the frozen corridor and the depth of the space. Cinematic environment, high background density, precise ice texture, mysterious and serene atmosphere. Anime illustration, great quality, best quality.
