character: kaga_sumire, A full body shot in a vertical phone wallpaper composition, captured from a low-angle view with the character positioned in the lower 70% of the frame and the top 30% left as clear negative space. Kaga Sumire is crouching in an explosive starting-block pose on a stadium track, her fingers gripping the synthetic surface and her leg muscles tensed for a sprint. She has grey hair and blue eyes with a distinctive mole under her eye, wearing a natural bare face and an intense competitive smirk. Her attire consists of a sexy, tight athletic sports bra and micro running shorts in black and purple with purple racing stripes. The scene is set on a floodlit night stadium track, with sweat glistening on her skin under powerful overhead lights. The background features the dark expanse of the stadium and the blur of the track. The lighting is high-contrast and dramatic, with a color palette dominated by deep blacks and vibrant purples, creating a high-energy and focused atmosphere.
