Vertical 2:3 highly detailed technical anime illustration on flat cobalt blue. Exact rear view of an adult feminine mechanical angel floating upright on centerline x50%. Long black hair falls from head at y27% to hips at y66%, concealing torso and most buttocks. Pale lavender bare legs extend together, ankles close, soles facing partly back, feet finish at y89%; restrained anatomical depiction, no exposed genitals. Symmetric enormous wings begin behind shoulders at y32% and curve outward upward beyond both top corners. Dense rows of pale lavender chrome feather blades make two rising arcs, black machinery and intense royal blue inner feathers beneath. The central gap above head remains blue, wide enough to see a thin vertical black construction line. Two huge long black rotary cannon assemblies suspended diagonally down beside hips: left from x30%, y41% to x4%, y86%; right mirrors to x96%, y86%. Pale angular white armor fairings on outer hips, intricate rods and layered plates within. Bright flat lavender feather planes against pure black mechanical gaps, sharp white chrome facets, cool blue shadows; no warm light. Crisp engraved pen contours, fine scratches and dry printed grain, not realistic human skin. Vertical small white title near x66%, y3%: '9' then '機械天使・零式'. Narrow dense right margin column of tiny technical notes headed '仕様', several tiny color swatches lower right. Microtext not legible at source size, use subtle nonsemantic fine lines rather than invent specifications. Lower center trailing dark registration streaks extend beyond feet. Negative: frontal angel, feathered organic bird wings, skin gradients, golden halo, wings cropped midway, short hair, bent knees, gun firing, large readable body copy, sci fi landscape.
