Why there's lighting

umamusume, jujutsu_kaisen. A medium shot of a solo horse girl with dark blue hair and purple eyes, smiling happily at the camera, standing on a sandy beach with ocean waves in the background, captured from a low angle. She is a teenage girl with horse ears adorned with star-shaped ear accessories, wearing the Jujutsu High prefecture uniform consisting of a black jacket over a white collared shirt, black pants, and a dark blue necktie. Her hands are naturally resting at her sides, fingers relaxed. The beach features gentle waves lapping at the shore, seashells scattered on the sand, distant horizon under a partly cloudy sky. Dramatic lightning streaks across the sky from left to right, casting sharp highlights and deep shadows with soft ambient glow. Muted, mid-saturation anime illustration style with clean sketchy linework, flat color blocks, subtle paper grain texture, minimal shading, and ethereal atmosphere.
