Yuuji Kanehara is a worker at a drone factory. As the factory is isolated from outside communication, and as a result the sibyl network, the staff at the factory have only themselves to entertain them. More to the point, they have Yuuji. He is bullied and tormented, and his treatment is condoned by the factory management as they feel that this is a natural component of a healthy social heirarchy and that this behaviour is to be expected and is neccessary to keep people's stress levels down, a key factor in maintaining healthy psycho-passes, which otherwise cannot be measured.
