Voidoll is a humanoid robot whose body is made out of metal. She gives the tutorial to new users in Compass and takes on an administrative role in the world, observing how the humans fight. Her evil counterpart is Bugdoll.
She has "hair" in a twintail style as well as an ahoge on the middle of her head. Her hands are cylindrical and have display screens on the ends, allowing her to display fingers and generate solid claws out of them. Her face also works in a similar way, with her eyes being shows on a display screen. Due to her lack of a mouth, she mainly uses these eyes to emote, with a wide variety of expressions. Her feet are rounded at the bottom with a circle on the apex of the curve.
In her default skin, her body, hands, head and feet are made of white and black metal whilst her limbs and the underside of her twintails are made of a light blue metal.
