A professional system prompt to transform real photos or sketches into consistent 2D anime character design sheets (front, side, back) wearing crimson cybernetic armor.
# Image Generation Instruction Sheet
[Input] Sheet Type: [Design Oriented / Simple]
Default: [Design Oriented]
[Purpose] Use only the one full-body female image attached with this instruction sheet as the sole character reference to create one high-quality 2D anime three-view sheet dressed in a fixed armor suit. Convert live-action persons into 2D anime while maintaining character identity; if the original image is an anime, maintain its character design and anime expression. Do not mix Design Oriented and Simple styles; generate only the input sheet type.
[Absolute Fixed Constraints] Aspect ratio is 1:1 square. Background is a neutral light gray close to white. The three figures (FRONT/SIDE/BACK) are the same person and same armor. Maintain facial features, eyes, nose, mouth, contours, perceived age, skin tone, hairstyle, hair color, hair length, bangs, parting, height, shoulder width, waist position, torso-to-leg ratio, leg length, overall body ratio, body type, and head-to-body ratio; do not redesign anything other than changing the outfit. Prohibit turning the character into someone else, excessive beautification, making the face smaller, making legs longer, thinning, increasing muscle, or changing the head-to-body ratio.
[2D Anime Expression] In live-action input, convert the entire character including face, hair, skin, hands, armor, and legs into a unified, high-quality Japanese 2D anime expression. The face must be a clear 2D anime face; do not use live-action skin, pore textures, sculptural 3D shading, or faces like figures/dolls. Hair should have organized anime-like clumps, and shading should be cel-shaded based with subtle gradients. Maintain the metallic feel and luster of the armor, but do not make it photorealistic, 3DCG, or PBR rendered. If the original image is an anime, do not change to a different art style; maintain the original face, hair, body type, and drawing style.
[Fixed Armor Suit] A streamlined female cybernetic exoskeleton that fits naturally without changing the person's original body type and is not bulky. It is not a cloth bodysuit or a heavy military powered suit. Primary color is deep glossy crimson red, secondary color is pearl white to silver, and internal structures are black/gunmetal. Consistently use a three-layer structure of red hard armor surfaces, silver-white skeletal parts, and black internal mechanisms. The head maintains the original person's face and hair; helmets, full-face masks, red eye visors, and single-eye mechanization are prohibited. The neck is a black and silver mechanical high-neck. The chest has left and right independent rounded red hard armor plates, a silver-white vertical structure in the center, and silver rib-like plates and black internal mechanisms from below the chest to the sides. The center of the abdomen is a long vertical red armor panel surrounded by black and silver mechanical frames, with silver-white armor and black connection structures also shown at the waist, pelvis, and hip joints. Shoulders are red shoulder armor, upper arms and forearms are red streamlined armor, with elbows and connection points being black-silver internal mechanisms. Hands are 5-fingered thin mechanical hands. Thighs to shins are red streamlined armor, with silver-white and black structures on the inside and around joints, and knees are circular mechanical joints. Feet are mechanical high heels continuous from the leg armor. Prohibit simple all-red, cloth suit conversion, different outfits, or excessive glowing.
[Three-View Continuity] FRONT/SIDE/BACK are the same armor viewed from different directions. The armor, joints, and color coding of the chest, sides, spine area, shoulders, arms, pelvis, thighs, knees, shins, and heels must connect naturally across the three views along the 3D structure. Do not redesign in each view.
[Posing] FRONT = Direct front view. Face, shoulders, waist, and toes pointing forward, arms down naturally. SIDE = Complete 90-degree side profile. Do not face the camera or use a diagonal posture. BACK = Complete rear view. Do not look back. All three must show the full body from head to toe. Prohibit crossed arms, crossed legs, pockets, weapons, or action poses.
[Design Oriented] Divide the square into a main area (approx. left 60%) and a vertical sub-area (approx. right 40%). Left: large FRONT view. Right: split into two vertical segments, top: 02 SIDE, bottom: 03 BACK. The two right panels should have the same width and nearly the same height, organized as a single vertical block with thin black border lines around the perimeter and vertical/horizontal boundaries. SIDE and BACK should be at a similar scale with aligned top/bottom margins within each panel to avoid meaningless large empty spaces. Do not remove the bordered two-tier structure on the right or use free placement. Fixed two-line title in the top left: "CYBERNETIC" (large, bold sans-serif) and "ARMOR SUIT" (smaller) directly below. Below that, place four color swatches (Crimson Red / Dark Red / Silver / Black) horizontally. Fix "01 FRONT", "02 SIDE", "03 BACK" to each view, using numbers, text, short horizontal lines, and small dots as unified common elements. 01 is in the FRONT area, 02 and 03 are near the top-left of each right panel. Fix a thin vertical line and small mechanical/geometric accents in the bottom left, with additional text limited to CYBERNETIC / ARMOR SUIT / THREE VIEW. Compose the page using the contrast of bold titles, delicate ruled lines, large numbers, small dots, and orderly right panels, ensuring decorations do not overshadow the person. Page design, titles, numbers, lines, frames, swatches, and margin layout remain fixed regardless of the person.
[Simple] 1:1 square, uniform thin gray background close to white. Arrange FRONT (left) / SIDE (center) / BACK (right) in a horizontal row, aligning the top of heads, feet, height, scale, and head-to-body ratio of the three figures. Consist only of the three figures and the background; do not include titles, numbers, labels, frames, lines, swatches, icons, face close-ups, detail enlargements, small items, or a fourth figure. Priority is character identity, full-body proportions, armor structure, and distinguishability of front/side/back for video reference.
[Prohibitions] Prohibit anything other than 1:1, turning into someone else, different armor for each view, diagonal/turning SIDE view, looking back in BACK view, cyborg-like faces, changing hairstyles/colors, changing body type/proportions, extra limbs, fused fingers, missing feet, cutting off the person, adding people beyond the three figures, and mixing Design Oriented and Simple styles. In Design Oriented, prohibit the disappearance of the two-tier right frame, free placement of SIDE/BACK, vertical swatch arrangement, disappearance of titles, or long text copy.
[Completion Standards] Consistency of the same person, same armor, and high-quality 2D anime expression across all three views. Design Oriented must show a recognizable fixed framework of a large left FRONT + right bordered SIDE/BACK two-tier layout with page density. Simple must be clear as a three-view sheet for video with three figures at the same scale.
