Ex-soldier Juzo Inui has one question--who turned him into a cyborg and erased his memories? After the war, cyborg soldiers known as the Extended were discharged. Juzo Inui is one of them, a man whose body was transformed, his head replaced with a giant gun! With no memory of his previous life--or who replaced his head and why--Inui now scratches out a living in the dark streets of the city as a Resolver, taking on cases involving the Extended. Dr. Andy Wachowski was the genius who developed the basic theory of Extension technology. But once he saw what became of his creation he turned against it, becoming the leader of the anti-Extended terrorist organization Spitzbergen. Now, in an attempt to control Juzo, Spitzbergen threatens Tetsuro. Berühren's Resolvers Pepper and Gun Slave Unit Seven are after Juzo as well. Juzo has plenty of cases to deal with now--it's just too bad he's not getting paid for any of them!.
