character: matsumi_kuro, matsumi_yuu. A wide, side-view shot captures matsumi_kuro and matsumi_yuu running joyfully along a pristine, white sandy beach. Both girls have long brown hair and are wearing classic old-style school swimsuits, their expressions filled with happiness and bright, open-mouthed smiles. They are positioned side-by-side, captured in mid-stride with their arms swinging naturally as they race across the shoreline. The background features a turquoise ocean where the gentle waves crash against the sand, with the water sparkling intensely as it reflects the brilliant sunlight. The lighting is bright and airy, utilizing a high-key color palette of vivid blues and whites to convey a refreshing, energetic summer atmosphere with a clean anime illustration style.
