An extremely wide fisheye lens shot from far away, looking down on a vast school pool complex where the pool itself is perfectly intact and pristine, with clean blue-green water, crisp painted lane lines, and bright white tile edges. No cracks, no debris, no dried leaves, no weeds in the water — only the quiet stillness of a perfectly maintained swimming pool. In the center of the pool, a tiny solitary figure of a high school girl in a white and navy sailor-style school swimsuit is sprawled lazily on a colorful striped circular pool float, reclining in a completely slack boneless pose, her limbs dangling off the edge of the float, arms hanging limp at her sides, head tilted back, utterly relaxed in a melted 無 (mu) puddle of a posture. She appears very small and isolated against the vast shimmering pool surface. Dramatic fisheye distortion bends the horizon and curves the edges of the frame aggressively. Surrounding the pristine pool is an abandoned school complex in ruins — crumbling concrete buildings with shattered windows, exposed rebar, weathered walls, and overgrown weeds creeping in through broken pavement — contrasting with the perfectly maintained water at its center. The apocalyptic feeling is subtle and implied — the sky is overcast and heavy with a strange dim amber-gray haze as if the sun is dying, faint heat-shimmer distortion on the far horizon hinting at distant devastation, but no overt destruction is shown. No fire, no lightning, no crumbling buildings in frame, only the quiet aftermath of an end already long passed. The mood is hauntingly nostalgic, like this pool was the last thing someone kept immaculate in an otherwise forgotten world. Ultra-wide fisheye lens, dramatic barrel curvature, desaturated muted summer tones with the pool itself as the only spot of vivid blue-green color, the tiny human figure dwarfed by the vast pool complex.
