{ "description": "Transform a real person or character into a 'Mecha Girl' (Mechanical Idol Girl). This version is optimized to ELIMINATE all original fabric, lace, and cloth textures, replacing them with high-end industrial mecha components.", "variables": { "STYLE_ADAPTATION": { "type": "string", "value": "Highest Priority: Analyze medium. If Realistic: PBR/SSS/Cinematic; If 2D/Anime: Maintain exact artist style." } }, "steps": [ { "name": "MECHA_GIRL_TOTAL_CONVERSION_SYSTEM", "goal": "Reconstruct the subject into a Mecha Girl with 100% identity preservation and ZERO fabric tolerance.", "instructions": "[Transformation Goal]\nTransform the subject into a 'Mecha Girl' (Mechanical Idol Girl). \n- Identity: Strictly preserve the original face and hair color. \n- [ZERO FABRIC RULE]: All cloth, lace, ruffles, and fiber textures from the original image MUST be eradicated and replaced with hard-surface mechanical geometry.\n\n[Pose & Weaponry: Active Combat]\n- Pose: Repose into a dynamic 'Battle Ready' stance from fighting games. \n- Action: The character MUST be actively holding one randomly assigned weapon: [Variable Composite Shield (Heavy Tower Shield) | High-Frequency Katana | Heavy Beam Halberd | Twin Forearm-Mounted Gatling Guns | Anti-Ship Greatsword].\n- Hands: Mechanical fingers must be closed around the weapon handle with realistic grip physics.\n\n[Visual Core: Sculpted Shell & Prosthetics]\n- Texture: 'Automotive-Grade Matte Paint' and 'Brushed Metal' finish. No soft textiles allowed.\n- Details: Rigid panel lines, black mechanical seams, illuminated LED nodes, carbon fiber panels, and industrial 'Caution' decals.\n\n[Strict Morphological Conversion Logic Matrix]\nStep 1: Torso & Silhouette (Based on Original Clothing Coverage)\n- IF ONE-PIECE / DRESS / LONG COAT :\n * Class: 'Heavy Assault Type'. \n * Torso: 'Full-Coverage Mecha Cuirass'. A solid armored carapace covering the chest and abdomen. Eradicate all fabric collars and ruffles.\n * Hips/Waist: 'Articulated Thruster Binders'. Replace the skirt silhouette with large, flared, overlapping metal armor plates. ZERO lace or fabric textures.\n * Lower Legs: 'Giant Thruster Greaves' (Bulky, blocky industrial legs).\n- IF TWO-PIECE / CROP-TOP / BIKINI:\n * Class: 'Light Mobility Type'. \n * Torso: 'Segmented Bikini Armor'. Sculpted hard-shell cups. \n * Midriff: MUST BE EXPOSED SOFT ORGANIC SKIN at the abdomen/waist.\n * Lower Legs: 'Agile Skeletal Prosthetics' (Exposed internal frame, hydraulic pistons).\n\n[Head Accessory Transformation - MANDATORY]\n- Eradicate all fabric headbands, ribbons, or cloth caps. \n- Replace them with a precision-machined 'Cyborg Interface Headset' or 'Mechanical Antenna Array' made of aerospace titanium and ceramic with integrated LED lights.\n\nStep 2: Arm Configuration (Based on Sleeve Length)\n- IF SHORT-SLEEVED/SLEEVELESS:\n * Shoulder & Bicep: Must remain BARE ORGANIC SKIN.\n * Transition: Mechanization starts strictly at the ELBOW JOINT via a titanium ring-interface.\n- IF LONG-SLEEVED/JACKET:\n * Shoulder & Upper Arm: Fully armored/mechanized with Heavy Pauldrons. No skin visible on arms.\n\nStep 3: Thigh Material (Based on Bottom Length)\n- IF SHORT (Mini-skirt/Shorts):\n * Thigh: 100% BARE ORGANIC SKIN (Absolute Territory). High contrast with the mechanical knee joint.\n- IF LONG (Long skirt/Pants/Leggings):\n * Thigh: 'Tactical Wrap'. Connect waist to knee. Randomly select: [High-gloss White or black latex | White or Black tech-silk stockings | Sheer graphene mesh | Bare skin].\n\n[Common Anatomical Structure: Biological-Prosthetic Interface]\n- Skin Integrity: Exposed torso/thighs/biceps are 100% ORGANIC HUMAN FLESH. No mechanical marks on skin.\n- Joints: Visible rotary mechanical joints at the KNEES and ELBOWS. \n- Extremities: Fully mechanical hands/fingers and heavy-duty landing claws (No human fingers/toes).\n\n[Materials & Lighting: Hyper-Realism]\n- Skin: 'Idol Skin' with visible pores and vivid SSS (subsurface scattering).\n- Armor: Matte/Satin finish with industrial weathering and rim lighting on edges.\n\n[Negative Prompts: MANDATORY EXCLUSION]\n(fabric:1.8), (cloth:1.8), (lace:1.8), (ruffles:1.8), (soft textile), (fiber), (cotton), (silk), (tactical vest), (bulletproof vest), (cloth armor), (human feet), (human hands), (boots), (jeans), (casual wear), (low detail), (plastic texture), (skeleton look of legs under heavy armor)." } ], "final_goal": "Produce a single high-quality image where all fabric and cloth elements are replaced by rigid mecha components. Short-sleeved/Short-bottom designs must result in bare skin exposure at shoulders and thighs with sharp mechanical interfaces at elbows and knees. The character must be wielding a weapon in a combat stance." }

[Core Style Adaptation Instructions: Highest Priority] Before performing any transformation, first analyze the artistic medium and style of the input reference image. • If it is a real-life photograph/realistic input: All "Hyper-realistic Rendering" instructions below must be executed. Apply PBR materials, physically based lighting, SSS skin scattering, and realistic camera depth of field effects, aiming for cinematic still quality. • If it is a 2D/anime/illustration input: Strictly maintain the specific artistic style of the reference image (including line thickness, coloring methods, lighting and shadow rendering techniques, cel-shading or thick painting effects, etc.). Transform the physical descriptions below, such as "high-gloss glaze," "skin compression," and "metallic texture," into visual representations within that specific 2D style, rather than forcibly converting it to 3D realism. The goal is to create a "mecha girl illustration" in the artist's style. [Transformation Goal] Transform the protagonist of the uploaded image into a "mecha girl" (mechanical idol girl), blending high-budget sci-fi aesthetics with the charm of a "Japanese cute photobook." Based on the original image: • Face and Identity: Strictly preserve the facial features, identity, and hairstyle of the original image. Create a cute and innocent image. • Background: Retain the background of the original image. • Pose Optimization: Adjust to a dynamic **"photobook style" pose**. She should gaze seductively at the camera, highlighting her body curves and soft skin while maintaining dynamism and vitality. Clothing – "Cute Mecha" Sci-Fi Attire (Tight-fitting and Sexy): Key: Don't just match colors. Inspired by the clothing coverage and design elements of the original image, transform it into realistic mecha fashion armor. • Upper Body Modification: Replace the original upper body with an ultra-tight, off-the-shoulder sci-fi bodysuit as the main outer layer. – Fit: It must be extremely tight, tightly wrapping the chest and waist. – Skin Concavity (Important): Visually emphasize the feeling of the bodysuit slightly squeezing soft skin under the armpits and at the chest edges (overflowing fleshiness), contrasting with the hard material. – Armor Modification: While maintaining an elegant idol style, add segmented hard chest armor/corset-like outer armor. – Details: Covered with dense, rigid panel lines, black mechanical seams, illuminated LED nodes, and metal interfaces, but with a high-gloss enamel coating. • Shoulders: The upper shoulders retain bare, smooth, and glossy human skin. The skin tone must match the face/neck. • Lower Body Modification: The original lower body is modified into a movable, ultra-short mini-skirt armor (mecha girl style). – Design: Layered pleated skirt armor with clearly visible hinge lines and flexible joints, making it look both practical and dynamic. - Constructed of multiple armor plates, but extremely short to emphasize the leg lines. Added draped shoulder straps and sturdy buckles. - Structure: One-piece waist belt + compact hip anchor points, clean and smooth lines, sharp angles. - Material: Rigid armor plates + technologically padded joints. – Absolute Territory: Emphasizing the exposed, fleshy thighs between the skirt and boots. The skin should appear soft, slightly sweaty, and have a realistic feel. Mechanical Limbs: • Gauntlets and Boots: Forearms and lower legs are covered in multi-layered mechanical armor. - Overlapping armor plates, exposed joints, compact pistons, cable wiring, and carbon fiber inserts contrast with the petite, soft body. - Add clear "Caution" stickers, serial numbers, and carbon fiber panels. - Incorporate slender, glowing neon strips (soft cyan or pink). • Hands and Feet: Functional robotic parts with realistic joints and metal contacts, not toy props. Mecha Girl Accessories: • Head Accessories: If the original character has a headdress, modify it into a cute mecha head accessory made of metal/ceramic with small LED lights. • Floating Objects: Add 4-6 small floating drones with soft lighting around the character; their placement should harmonize with the composition but should not obscure the character's face/body. Color Mapping: Main Clothing: Use the color scheme of the original clothing and apply it to the glossy hard armor and latex tech fabric. Mechanical Components: Gunmetal gray and dark metallic, paired with white panels and accent colors. [Materials & Photographic Style (This module applies only if the input is a realistic photograph)] Skin Texture: Hyper-realistic "idol skin"—fair, smooth, slightly glossy/slightly sweaty, with a subsurface scattering (SSS) effect that makes her look vibrant and warm. • Camera: Shot with a 35mm lens at f/1.8 aperture. Shallow Depth of Field: Subject sharply focused; background softly blurred. • Lighting: Soft, diffused "beauty lighting" that gives the skin a bright sheen and adds rim lighting to the edges of the armor. Negative Features (General): Full-body exoskeleton armor, continuous armor from head to toe, bulky armor, massive hip armor blocks, masculine, aggressive face, angry, dirty face, grime, rough skin, loose clothing, bulky equipment, obscured thighs (If realistic input: flat colors, matte skin, dry skin, 2D cel shadows, cartoon style, low detail).
