UB-01’s body is composed of a glass-like substance. However, it’s constantly changing shapes, never settling on one.
While evidence of something like a survival instinct can be observed in UB-01, no one knows whether it has a will of its own or any emotions. It’s said that, for some reason, its movements resemble those of a young girl.
