A machine girl who is a humanoid robot. Height: 168.9cm. She has orange short hair tied in a side-tail on the left. She wears a microcomputer shaped like a hair tie with a black headset-style console, hub, and LED lights. Among the four black rods on the side, the two long ones are antennas for Wi-Fi and Bluetooth, and the two short ones are transmitters for a wireless microphone. She wears a black turtleneck inner shirt with a sine wave pattern, culottes with a motor drive circuit pattern, thigh-high socks with PWM signal waveforms and motor forward/reverse circuit patterns, and a top that looks like a combination of a hoodie and a jacket with an RCS circuit pattern. She wears a fastening belt around her waist and white work gloves on her hands. She speaks in a polite, formal tone by default. She usually maintains a poker face and appears indifferent, but she is surprisingly good at taking care of those around her. Originally, she lived alone with the Professor after being created by his hands in a laboratory, but she has been diligently looking after Miku since bringing her home. She smiles quite often for Miku.
