A medium shot from a side profile angle, positioned slightly away from the subjects, showing two high school girls standing side-by-side in a dimly lit aquarium. On the left, Girl A, dressed in light summer casual wear, gazes at the tank with sparkling, wide-eyed wonder, her hands resting gently at her sides. To her right, Girl B, also in summer attire, reaches out her arm toward the glass as if trying to touch the fish swimming within. They are positioned before a massive, luminous aquarium tank filled with shimmering water, where dense schools of silver fish swirl around a few solitary, vibrantly colored tropical fish. The surrounding indoor environment is dark and atmospheric, creating a sharp, brilliant contrast with the vivid, glowing turquoise light emanating from the water. The visual style is a high-quality anime illustration with a transparent, airy feel, featuring soft caustic light patterns reflecting on the girls' faces and clothing, emphasizing a serene and magical summer mood.
