Sứa vũ trụ trong ga tàu điện ngầm ngập nước

Vertical cinematic Korean webtoon fantasy illustration of two children standing ankle-deep in reflective water inside a dark, flooded, decaying subway concourse beneath an enormous translucent cosmic jellyfish. - Overhead: One colossal translucent celestial jellyfish floating in the vaulted ceiling space, its bell glowing with stars, nebulae, cyan, violet, and deep blue bioluminescence, trailing long ribbon-like tendrils through the air. - Foreground Characters: Exactly two children in pale robes standing in the shallow water. On the left, [a dark-haired child with a long braid and a chest label reading "5"], holding a small flashlight casting a warm beam into the water. On the right, [a light-blond child with short wavy hair and a chest label reading "4.8"], holding a plush bunny and raising one hand to present a glowing blue orb. - Setting: Flooded underground station with escalators on the left, rows of concrete pillars receding into a bright circular vanishing point, cracked walls, water droplets, and small glowing jellyfish-like bulbs scattered across the water surface. - Style & Lighting: Detailed anime linework, luminous painterly shading, glossy floor reflections, volumetric mist, tiny floating motes, deep shadows, and magical cyan and purple rim lighting creating a melancholic, dreamlike atmosphere. - Constraints: No extra characters, no modern text or signage other than the numeric labels "5" and "4.8", no borders, no watermarks.
