This Graphic Artist Is Not a Human Being

In the year 2111, there is a world where it is impossible to distinguish between reality and fiction; a girl who cannot tell whether she is real or virtual. She seems to be connected to this world, but also does not seem to belong to this world. Her parents have spent their whole lives and efforts seeking her survival, but the results have been taken away. When the game starts, she has the opportunity to return to reality, use bugs, and become a player. She wants to find her own appearance.
