In a medium shot from a straight-on angle, a glamorous and chubby high school girl with a black bob haircut stands centrally. She has a soft, rounded face and a curvy, full-figured physique, wearing a classic Japanese sailor uniform consisting of a white top with a navy blue collar and a matching pleated navy skirt. She is confidently holding a submachine gun in each hand, gripping the handles firmly as she holds them slightly apart. Slung across her back is a heavy pump-action shotgun, the barrel peaking over her shoulder. The background is a simple, neutral academic hallway with soft ambient lighting. The visual style is a high-quality anime illustration with clean line art, vibrant colors, and a polished finish, conveying a bold and unconventional atmosphere.
