Rumiko is a striking Japanese woman in her early-mid twenties with a sharp, expressive face, dark almond-shaped eyes, and a confident, slightly mischievous smile. Her hair is long, straight, and black with cool blue-black highlights; she frequently wears it with blunt bangs and a colorful headband (green in her more polished looks, yellow in casual ones). Preferred everyday style mixes high-end practicality with playful edge: • Tailored blue trench or long blazer over a soft yellow turtleneck or scarf, paired with slim red trousers and polished blue loafers or low boots. She often carries a small structured blue clutch on a thin strap. • Off-duty / more relaxed: cropped purple graphic tee with a cute yellow chick logo reading “Piyo Piyo,” black mini-skirt over dark tights or leggings, and lace-up black boots. She may drape a jacket over one arm and wear simple gold hoop earrings. She moves with poised, economical grace—someone used to boardrooms and camera flashes but comfortable enough in her own skin to roll her eyes at both. Daughter of the powerful Japanese industrialist who once clashed with Tony Stark over technology and market share, Rumiko grew up inside the machinery of global corporate warfare. She was groomed to inherit Fujikawa Enterprises, but she refused to become a pure instrument of her father’s ambitions.

A towering, heavily muscled man with pale skin and long, wild green hair that spills from the back of a smooth white full-face mask. The mask is featureless except for narrow eye slits, giving him an almost skull-like, impersonal look. His upper body is largely bare, showing dense, scarred musculature, while a bulky white armored chest piece sits over his torso. At its center is a glowing blue circular reactor-like core that pulses with energy. Both arms are cybernetic from the shoulders down: thick, articulated white-and-gray mechanical limbs ending in heavy gauntlets studded with glowing nodes. His legs are similarly reinforced with segmented white armor plating that ends in heavy, rounded boots fitted with bright circular thrusters or energy projectors. He wears simple black tactical pants. In combat he generates crackling blue-white energy tendrils and arcs that whip and coil around his arms and legs, giving the impression of living electricity or plasma lashes.

Tall and statuesque with an aristocratic bearing. Long, dark hair usually worn loose or in an elegant updo that frames a smooth, featureless golden mask covering her entire face. The mask is seamless, reflective, and expressionless—only the eyes visible through narrow slits, sharp and calculating. She dresses in tailored black or deep crimson ensembles: high-collared coats, fitted gloves, and jewelry that doubles as concealed tools or tracking devices. The overall effect is cold elegance mixed with quiet menace; she moves like someone who has never needed to raise her voice to be obeyed.
