Goal: Create a clean anime concept art reference sheet for a {argument name="character name" default="Samurai Mecha Girl"}, combining a school-uniform samurai heroine with exposed light-mecha prosthetic limbs, presented as high-resolution monochrome production-design line art with small technical notes.
Canvas: Vertical portrait character sheet, off-white paper background, thin black outer border, 3:4 aspect ratio. Use crisp black and gray pencil/ink linework, minimal shading, no full color except a small color guide. The overall look is a Japanese setting-materials sheet, precise and highly detailed.
Layout: Top-left large English title “Samurai Mecha Girl” with smaller Japanese subtitle “侍機巧娘” below it. The left and center two-thirds contain the main full-body character illustration. The right third is a boxed head-turnaround panel. The bottom area contains weapon and mechanical-part diagrams. Keep the page airy, technical, and neatly ruled with thin divider lines.
Main subject: A 17-year-old anime girl with {argument name="hair style" default="short straight bob hair with blunt bangs"}, serious eyes, and circular mechanical ear/head sensor modules. She wears a sailor-style school uniform with scarf, short pleated skirt, thigh-high stockings, and mechanical armor integrated into one arm and one leg. Pose her kneeling dynamically: one knee down, one cybernetic leg raised, torso angled forward, one mechanical hand braced near the ground, and the other hand holding a katana horizontally above her head. The katana has a wrapped handle and a long slightly curved blade. Her mecha limbs are detailed with pistons, circular joints, armor plates, cables, segmented fingers, and heavy boot components.
Visible text and labeled sections: Include exactly 7 major text/detail blocks: 1) top-left title block with “Samurai Mecha Girl” and “侍機巧娘”; 2) a stats box listing “TYPE : ASSAULT”, “CLASS : LIGHT MECHA”, “HEIGHT : 158cm”, “WEIGHT : 49kg”, “AGE : 17”, “AFFILIATION : UNKNOWN”; 3) a “CONCEPT” block with short Japanese paragraph lines; 4) a “SPEC” block with Japanese bullet points; 5) a bottom weapon section labeled “武装” and “ENERGY KATANA / エネルギー式刀剣”; 6) a bottom mechanical parts section labeled “ARM UNIT / 腕部ユニット” and “LEG UNIT / 脚部ユニット”; 7) a right-side lower notes area with “COLOR GUIDE(参考)” and “DETAIL”.
Right-side head turnaround panel: Add one bordered panel titled “頭部ラフスケッチ三面図”. Inside it, show exactly 3 head drawings stacked vertically and labeled “FRONT”, “SIDE”, and “BACK”: front view with face and headband, side profile showing the circular ear mechanism, and back view showing the bob haircut and rear of the mechanical module.
Bottom diagrams: In the weapon box, show exactly 1 horizontal energy katana diagram with a wrapped grip. In the mechanical parts box, show exactly 5 separate component drawings: two arm-unit views on the left and three leg-unit views on the right, each rendered as detailed mechanical line-art studies.
Color guide: Include exactly 6 small square swatches with labels: main armor dark iron, sub armor white gray, accent red, mechanical joints gold, cloth dark blue, hair brown, plus a small orange eye/accent swatch if needed; keep these as the only colored elements on the page.
Style constraints: Use refined monochrome anime drafting, thin clean outlines, technical callout-sheet composition, high-detail mechanical design, subtle paper texture, sharp readable typography, no background scenery, no dramatic lighting, no painterly rendering, no extra characters.
