School Uniform Warrior with Giant Hammer

Against a starkly divided black and white background, a girl with silver-white short bob hair wears black and gold mechanical armor, gazing forward with cold eyes. Her sharp sapphire blue eyes hold unwavering resolve toward the enemy and overwhelming confidence, while a subtle smile with slightly upturned lips shows the composure of a warrior who enjoys combat. The silver-white short bob frames both cheeks creating a clean silhouette, and a dark red ribbon tied on her white school blouse reveals the dual identity of student and warrior. Full armor with intricate gold trimming on a black body covers her shoulders and torso, sapphire blue gems on both shoulders glow like power sources, and the silhouette of a massive hammer-type weapon rises imposingly behind her back. Gold gauntlets and arm guards with geometric patterns showcase precise mechanical design, while the armor's angular silhouette emphasizes the strength of a combat weapon. A mecha fantasy illustration with dignified midnight black and royal gold colors, capturing an overwhelming and charismatic moment of a warrior girl wearing mecha armor over her school uniform.
