Meta ( also know as GNW-0021 Medical Treatment and nursing Automaton, MeTA ) is a robot with the appearence of a teenage girl. Initially built to help in the hospital, she was chosen to be the test subject of a large-scale experiment, the study of the relationship between humans and robots.
Meta is so advanced that it's impossible to guess that she's not human at first glance. Having an attractive face, advantageous curves and a skin of incomparable softness, Yukito quickly falls "under her spell" and has a hard time believing that she is only a robot.
It's her personality that betrayed her. In order to be integrated by Humans, Meta must look like a human and behave and talk like them. To achieve this, she copies the "mimics" of her favorite characters to express her emotions ( Fufuri ~ ). She also has a great interest for all kinds of sports activities.
She is very popular at school, her closest friend seems to be Ayaka.
Since his arrival, she has taken a keen interest in Yukito<hidden by spoiler settings> ( she produces data that she doesn't understand when she is with him, in a first time ).
<hidden by spoiler settings>Her "mother" is Rikka.
Meta isn't a robot with a pre-programmed personality. She is a robot that "builds herself" with the experiences she lives, like a child growing up over the years.
She seems to understand very well the feelings that others experience and she often plays matchmakers.
She knows a lot about sex but has never experienced it.
In her route, we learn that her life span is two years and that she is nearing the end of her second year of operation.
