"Vertical 9:16 anime-style sky in ultra-detailed 4K resolution. A vast, painterly sky stretches endlessly, filled with massive, textured clouds in complex folds, subtle contours, and soft ridges. Gaps between the clouds reveal patches of baby-blue sky and warm sunlight beams filtering downward. Below, a mystical landscape fades into a dreamy blur. In the foreground stands an anime-style girl with shoulder-length dark hair and intense red eyes, inspired by Saya Otonashi from Blood+. She wears a traditional school uniform with a red ribbon and blue skirt, posed dynamically. She holds a katana with both hands in a ready stance, blade angled diagonally downward, tip glowing faintly, grip firm and focused. Her expression is serious and calm. Wind slightly lifts her hair and ribbon. Soft edge lighting surrounds her figure, with detailed cinematic lighting and subtle ambient haze. The color palette blends pastel blues, pinks, and golden sunlight, evoking a nostalgic, emotional atmosphere with ethereal, layered depth."
