四機械臂女戰士持藍色光刃，身處哥德式場景

提示詞

A dramatic dark fantasy light-novel cover illustration in a square format, featuring a fierce female warrior centered in a dynamic lunging pose inside a dim, ruined, cathedral-like or industrial gothic interior with a smoky blurred background and warm floating embers. She has long silver-white hair in a high ponytail whipping violently to the right, pale skin, and a deliberately obscured or featureless face. Her body is enhanced with four black mechanical arms in total, built from intricate clockwork and segmented metal joints, extending spider-like around her. She wears a tattered black dress-like battle outfit with armored corset detailing, belts, straps, a garter on one thigh, and biomechanical leg armor. Count exactly 4 arms visible: 2 upper arms and 2 lower arms; count exactly 4 glowing energy blades, one held in each hand, translucent neon blue with crystalline edges and magical circuitry-like light patterns. Emphasize the contrast between matte black metal, torn fabric, pale skin, and electric cyan weapons. The composition should feel cinematic, high-detail, intense, and heroic, with sharp focus on the character and soft depth-of-field in the background. Add ornate Japanese cover typography in metallic gold with subtle beveling and glow: at the top, small genre text 《バトルアクション》; below it, a large main title クアッドアームの静寂; beneath that, a smaller subtitle ～四本腕の女傭兵と錆びついた世界の約束～. Near the bottom, add a large centered quote in gold Japanese text 「僕は君の未来を高値で買いに来た」; directly below it, a smaller line ——時計仕掛けの運命が、今動き出す. At the very bottom center, place the author name ざっ in large gold text with elegant ornamental divider lines on both sides. Use a luxurious fantasy-book-cover layout, moody sepia-and-charcoal palette with bright cyan highlights, ultra-detailed anime-inspired realism, and a polished GPT-image-2 editorial illustration style.
