Full body shot in monochrome anime illustration style with a checkered background, featuring a solo focus on the central girl standing expressionless, holding a flag with polka dot pattern, blunt bangs framing her face, accompanied by another girl beside her. The primary character wears a short-sleeved serafuku school uniform consisting of a white collared shirt with dark sailor collar and neckerchief, paired with a very short pleated miniskirt, knee-high socks, and sturdy boots; her extremely long hair flows down her back. The secondary girl mirrors her uniform and stands slightly behind to the right, both positioned centrally against an intricate black-and-white checkered tiled wall that creates geometric depth. High-contrast black ink lines with minimal shading, sharp details on fabric folds, hair strands, and flag texture, conveying a stark, emotionless atmosphere.
