A black-haired girl in a white traditional Chinese dress holding an assault rifle, standing in a serene courtyard with willow branches swaying and petals falling. Suddenly, her eyes glow with determination as her warrior spirit awakens — the dress flows like water and transforms into sleek silver-gold mecha armor, shoulder-mounted energy shields deploy, mechanical blade arms extend from her forearms, tactical backpack and missile launchers appear at her waist, her hair ornament blooms into a glowing ancient insignia crown, surrounded by golden-red light halos and particle streams. Her posture shifts from graceful to fierce, ready to enter battle.
