A (strict close-up portrait:1.5) in an anime illustration style, framed as an (extreme close-up:1.8) focusing only on the face, neck, and (beautiful smooth clavicle and upper chest:1.4) of an original character named Ruki. She has long, messy, unkempt, solid pitch-black hair with an iridescent sheen like a raven's wing that cascades around her neck and shoulders. Her expression is intense and battle-crazed, with glowing blue eyes and sharp, cold irises staring directly forward. Intricate glowing blue tribal dragon tattoos pulse with neon-like light across her neck, collarbone, and shoulders. The background is a minimalist, inky black. The scene is rendered with high-contrast, dramatic chiaroscuro lighting, emphasizing the sharp contours of her pale skin and deep black hair, creating a cold and aggressive mood.
