katia, 1girl, large breasts, (masterpiece, top quality:1.5), (3D anime style:1.4), (Unreal Engine 5 render:1.3), (Japanese ACG aesthetic:1.3), (single girl:1.3). Character: beautiful adult woman, crimson-red hair base with cyan-blue forked lightning streaks swept to the left side exposing the right half of her face fully, amber-gold irises with cyan-blue pupil highlights, tall athletic figure. Right half of her face from cheekbone to temple features raised hannya mask patterns emerging from the skin surface as living tattoo-relief — the pattern includes the iconic hannya horn bud on the right forehead, fierce brow ridge line, and snarling mouth corner motif, all rendered in slightly raised cyan-blue scarlet-tinged relief against her skin, the pattern is subtle and elegant not grotesque — more like ornamental demon calligraphy than horror, left half of face remains flawlessly beautiful creating stark duality. Outfit-outer: frost-blue-white structured battle robe with standing collar slightly parted at front, asymmetric diagonal cutaway on right torso — originating from collar base near right clavicle sweeping diagonally across chest to left waistline, left side fully intact, standing collar reveals ink-black scalloped lace inner lining through parting. Outfit-inner: fitted ink-black bodice panel visible beneath cutaway covering collarbone to just above hip bone, terminating with scalloped lace hem and cyan-blue conductive thread along hemline, skin fully exposed below hemline with no fabric continuation. Outfit-lower: form-fitting frost-blue-white riding trousers from natural waistline, cyan-blue armored thigh garter on outer thigh. Action: close-up three-quarter portrait facing slightly to her left — the angle maximizes visibility of the hannya pattern on the right cheek while keeping the beautiful left profile in frame, raptor talon fingertips gently touching the hannya horn bud on her own forehead as if checking its growth, expression composed and contemplative — the hannya pattern suggests fury but her expression conveys calm control over the demon within, hair swept aside deliberately to display the full pattern. Environment: dark interior with a single warm amber light source from the left illuminating the beautiful side of her face, while the hannya-patterned right side falls into cool cyan-blue shadow creating natural half-light-half-shadow split, a polished dark surface below reflecting her face in mirror-image doubling the duality effect, volumetric stillness with no environmental distraction. Color-system: frost-blue-white outer robe, ink-black inner bodice with scalloped lace hem, cyan-blue hannya relief pattern with subtle scarlet undertone, crimson-red hair with cyan-blue streaks, amber-gold eyes, warm amber left light and cool cyan-blue right shadow. Technical: skin-relief hannya pattern rendering with subsurface depth, half-face light-shadow split precision, polished surface mirror reflection, scalloped lace hem detail, hannya horn bud raised texture, 8k resolution.Karen Charlotte11
