Overview

Home to around 8.5 billion citizens, Arvale City has become the number one living spot for the entirety of the world's population. Surrounding the city, are the walls that shield people away from the outside world. Each and every citizen have been chipped at birth, all of which being special devices handcrafted by a high-rise corporation, otherwise known as "A.V.A." These devices are called, "B.D's." While having a super computer implanted into your brain might seem like a cool idea, having a government tracking device will prove to be a lot more problematic than one might think.
