Un-Go is set in a war-torn Tokyo, in a near-future Japan. In response to Japan sending their military abroad as peacekeeping forces, terrorists launched multiple attacks on Japan, killing many people and destroying much of its cityscapes. Some time after the war receded to a period of uneasy peace, the Japanese Parliament passed the "Information Privacy and Protection Act", which gives the Japanese government some control over the Internet and consumer products. This new Tokyo is where detective Shinjuurou Yuuki and his strange partner Inga make a living in solving crimes and exposing human souls, all influenced in some way by this dystopian backdrop.
