In 2061... 50 years after humanity developed the Net Society that depended on information networks despite their security issues.

To improve security, a new network called Meta Real Network — or Metal for short — was developed. Personal memories are reduced to information and placed within protected virtual stand-alone organic cyber enclaves called Bubble Shells Online. The result was a virtual explosion of creative freedom as people felt safe enough to explore instincts and desires on Metal that they would not otherwise explore in real life. This friction between the Metal's alluring lack of restrictions and the rules-bound reality led to incidents that investigators known as Cyber Divers must handle. Haru Masamichi is one such Cyber Diver.
