daikou-chan
The original avatar character of the VTuber Kson (as opposed to Kson herself).
Daikou-chan wears a black china dress with a cleavage cutout, black elbow gloves or detached sleeves, glasses, and long black hair tied up in a spiky high ponytail. Usually out of sight, but still present in her design, are red print shorts, fishnet pantyhose, and red-soled black shoes.
