character: tsumugi_kokage, Full body shot from a low angle of Tsumugi Kokage, positioned in the lower portion of a vertical phone wallpaper composition with the top 30% of the frame as clear negative space. Tsumugi is a girl with short blue hair, blue eyes, and a small bow hair ornament; she is captured mid-stride in a dynamic running pose, her arms pumping and feet barely touching the ground. She is wearing a sexy sporty trail running outfit in moss green, consisting of a tight-fitting sports bra and matching athletic running shorts. Her expression is one of focused determination with a natural, joyful smile, and her face is completely bare without makeup. The setting is a lush forest rally trail with dense foliage and towering trees; sunlight filters through the canopy in sharp beams, creating dappled patterns on the dirt path. The atmosphere is fresh and energetic, characterized by bright natural lighting, a vibrant green color palette, and a slight motion blur on the background to emphasize her speed.
