About

There exists a secret and mysterious prison called Fogland, where only the most wicked prisoners are sent. It is unnaturally vast and houses a proportional number of inmates. Within this place exists a substance called Fog, which looks like small blue balls. When consumed in large quantities, one of the consumer's greatest strengths becomes transcendentally powerful. Their physical body is also enhanced, though most manifest only one specific ability. The more Fog one consumes, the higher their power level becomes, leading many prisoners to plunder it from others. There is a downside: failing to consume Fog for a long period causes withdrawal symptoms. This phenomenon is simply called Limbo. Because the prison is so large, it is divided into sectors, and the strongest person in each sector is called a Shoulder. It is impossible to escape Fogland. Not only are there massive, high walls, but a being known as Hollow Win prevents anyone from leaving. His speed transcends imagination; if someone manages to get outside the walls, he pursues and kills them with overwhelming speed and power.
