Jig Kumonuma carries a peculiar curse. Whenever anyone attempts to hurt him, the device on his back reflects the damage back at them doubled, leaving Jig completely unharmed. Afraid of accidentally hurting others, Jig cuts himself off from his family and the world—until he learns of a potential cure in the busy city of Jinbo-cho. However, the city is a hazardous place where various species converge, and in its most seedy districts, the police are of no assistance whatsoever. Fortunately, Jig has the elite V&V Total Security Protection agency and its lead agent, Troma Yabusame, by his side. It also helps that Troma is invisible!
