Kasane Teto / Hatsune Miku

Hatsune Miku—more commonly known as Miku—is a young girl of 19 or 20 who resembles a robot. She's a slave in the same place as Teto and also a signaler. She's constantly assigned to work with Teto, which sometimes makes her angry. Miku constantly tries to prove through her work that she can be a better signaler, using the red and blue counting sticks, just like Teto.
Miku is very similar to Teto in appearance: they are almost the same height, have a slender figure, and long legs, like two robots. Miku has bright blue, voluminous hair with two long ponytails on the sides, each with a thin, dark red strand, almost the same color as Teto's hair. On her head is a headband resembling two red horns, reminiscent of drills, extending upward. Light bulbs with a round ball at the end glow dimly. Her bangs are slightly covered by black glasses, which are always worn on her head. They have red lenses, like the light bulbs, but with a white, frozen line drawn on the lenses, like a frozen pulse. Her bright blue eyes match her hair, with small, dark red pupils. She wears a black, wide, midriff-length T-shirt and a long, wide white coat that ends in a slit, with equally long, wide sleeves. She wears short, bright blue shorts with a fashionable bulge at the end, pulled over her T-shirt. She also wears long black boots and bright blue knee-high socks that extend slightly above the boots.
