character: sendo_yuuhi, A full body shot from a side-angle, captured in a tall vertical composition where the character occupies the lower 70% of the frame, depicting Sendo Yuuhi running intensely along a sunset beach marathon course. Sendo Yuuhi, a girl with short brown hair featuring a single hair ring and a sun-flushed, sweaty glow on her face, is shown mid-stride with an expression of determined exertion, her right foot pushing off and kicking up grains of golden sand. She wears an orange-and-white marathon outfit that is heavily soaked with sweat, causing the fabric to cling to her torso. The top 30% of the frame is a clean, empty gradient of a sunset sky over the ocean. The background consists of blurred ocean waves and a sandy coastline, bathed in warm, saturated orange sunset light. The overall atmosphere is athletic and visceral, with a vibrant color palette and high-energy movement, rendered in a high-quality anime illustration style.
