Nanny for ultrasound

A digital display shows white neon eyes. He wears a dark blue hard hat and red goggles that slide down onto the helmet. He has a mustache, but it's not too long. He wears a black turtleneck, a blue camouflage hooded jacket, and tall black boots. He's slightly obsessed with doors, though his door obsession has mostly subsided over the summer. He doesn't particularly trust the demolition workers (V, N, and J), but he doesn't forbid his daughter, Uzi, from talking to them, knowing no one will notice friends like them. Otherwise, Khan is usually quiet, constantly drinking from a mug with the inscription "Dad #1" and always carrying a wrench in his bag.

Face and Hair: She has short silver hair cut into a bob with side bangs. Her eyes glow a bright yellow neon light, and a black headband with five additional yellow indicator sensors adorns her head. Build: The robot's body has distinctly feminine contours (waist and hips). Her legs taper downwards and end in thin, sharp, cone-shaped stiletto heels instead of feet. Clothing: She wears a short, black, fitted jacket with a fur collar and cuffs. Wings and Tail: Massive metal wings with razor-sharp blades fold behind her back. She also has a long, thin tail, at the end of which is a syringe filled with bright yellow, corrosive nanite acid. At first glance, Vi appears to be a complete psychopath, sadist, and sociopath. She takes genuine pleasure in the brutal destruction of worker drones, often laughing during combat and demonstrating a complete lack of empathy.
However, behind this mask lies deep psychological trauma. She displays care, devotion, and selflessness towards Enu and Uzi. Her eyesight isn't very good, but she still goes without glasses, even though she sees much better with them.

A teenager with short purple hair and purple eyes appears onscreen. She has a rather complex personality, and few manage to cope with her; some even say she's broken and has system glitches. She wears a black hoodie, a black skirt, and purple leg warmers with black stripes.
