A wide-angle, dynamic action shot captures a girl with a sharp, serious gaze and intense eyes, swinging a massive blade formed from pure lightning downward in a powerful strike. She has beautiful, long black hair and wears a disheveled school uniform with a mini-skirt, both realistically drenched and clinging to her skin from the rain. Her figure features an emphatically large chest with a realistic sense of motion and sway. She is enveloped in a high-voltage energy effect, with a vivid purple and gold crackling lightning aura and electrical discharges erupting around her, while lightning bolt symbols rain down like droplets from the sky. The setting is a vast, open environment under a storm, emphasizing the scale of her attack. The visual style is a high-quality anime illustration with a realistic depiction of wet textures, high-contrast lighting from the electric flashes, and a dramatic, high-energy atmosphere filled with sparks and rain particles.
