Couverture de Light Novel avec Guerrière à Quatre Bras

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 industrial gothic interior. The background is smoky and blurred with warm floating embers. She has long silver-white hair tied in a high ponytail whipping violently to the right, pale skin, and an obscured, shadowed featureless face. Her body is fitted with exactly four black mechanical arms built from intricate clockwork and segmented metal joints, extending spider-like around her: two upper arms and two lower arms. Each of the four hands holds a glowing energy blade made of translucent neon cyan with crystalline edges and magical circuitry light patterns. She wears a tattered black combat dress with an armored corset, belts, straps, a garter on one thigh, and biomechanical leg armor. High-contrast aesthetic between matte black metal, torn fabric, pale skin, and electric cyan weapons, with sharp focus on the character and soft depth of field. Ornate Japanese book cover typography rendered in beveled metallic gold with a subtle glow: - Top: small genre text 《バトルアクション》 - Main title below: [クアッドアームの静寂] - Subtitle beneath: ～四本腕の女傭兵と錆びついた世界の約束～ - Bottom quote (large, centered): [「僕は君の未来を高値で買いに来た」] - Sub-quote line directly below: ——時計仕掛けの運命が、今動き出す - Bottom center author credit: [ざっ] flanked by elegant ornamental divider lines.
