Sampul Buku Fantasi Gelap dengan Tokoh Utama Wanita Berlengan Empat

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, Show every face clearly with natural, detailed facial features. 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 {argument name="headline text" default="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 {argument name="quote" default="「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 {argument name="author name" default="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.
