A masterfully detailed interior scene of "Chicago Gunsmiths," a cluttered yet organized workshop heavily inspired by Gunsmith Cats. A young woman with voluminous, messy wavy hair and large, soulful "Sonoda-style" eyes with multiple highlights is focused on her craft, meticulously cleaning a classic CZ-75 Pre-B pistol. The workbench is a treasure trove of "mechanical fetishism": scattered brass 9mm shell casings, a bottle of Hoppe’s No. 9 gun oil, a disassembled slide, and fine-tipped brushes. The background features walls lined with hyper-realistic firearms—Winchester rifles, Remington shotguns, and various handguns—all rendered with technical manual precision. The art style is pure 1990s OVA aesthetic, featuring crisp, bold ink linework and high-contrast cel shading. The character wears a ribbed tank top and a leather shoulder holster, blending a "cute, round-faced" aesthetic with a professional, lethal aura. The lighting is warm and dusty, with sunbeams catching the metallic sheen of the gun barrels and the fine texture of the wooden grips.
