A new chapter in the "Gantz" saga brings with it a new level of action and mayhem! The alien-hunting Gantz warriors are transported to their new mission, leaving behind their fallen comrades, Kurono and Izumi. Given no time to mourn, they find themselves in a completely unfamiliar location, well beyond the confines of Tokyo in the Dotombori district of Osaka. Even more surprising is an encounter with another group in Gantz suits. Are the members of this unknown team allies ...or deadly new foes?
