Far in the future, the lifeforms known as Gadoll suddenly arose as a threat to humanity. The last surviving humans on Earth confine themselves to the Tank, a lower district in the giant mobile fortress Deca-Dence. While the Gears who live on the upper floors are warriors who go out to fight as part of the Power, most Tankers are content to provide support from the backlines, butchering Gadoll meat and reinforcing defenses. Natsume is among those who would rather go to the front lines; undeterred by her prosthetic right arm, she seeks to join the small number of Tanker soldiers who join the Gears in combat. But despite her peers at the orphanage each receiving their work assignments, Natsume’s enlistment to the Power remains unapproved. In the meantime, she begins a job as a cleaner in an armor repair team led by the hard-nosed and apathetic Kaburagi, who seems to be more than he lets on. Though initially cold to his idealistic subordinate, he soon recognizes in her the potential to upset the status quo of the world. As Natsume’s new mentor, Kaburagi prepares her for the special and unique role as a game-changing bug in the system. [Written by MAL Rewrite]

The Great Kanto Desert, a sweltering wasteland of nothing but ruins and sand, is all that remains of post-apocalyptic Japan. The once fair population has been left to cling to the inhospitable dunes for survival. At least, that is the case for normal people. For those who have spent a little too long in the Kanto sun, the desert offers a wondrous opportunity to make a name for themselves. One such person is the masked handyman "Sunabouzu," or Desert Punk, who has forged a legendary reputation for always finishing his jobs, no matter the nature or cost. Cunning and ruthless, he has become a force of crude destruction to the other desert people. However, the "Vixen of the Desert," Junko Asagiri, discovers that Sunabouzu is not without his weaknesses—he is easily swayed by his insatiable lust for large-breasted desert babes. Following their chaotic adventures through the Kanto Desert, Sunabouzu features a bizarre cast of personalities who entertain themselves with senseless violence and perversion in a world long destroyed by their forefathers. And just like them, they have not learned a damn thing. [Written by MAL Rewrite]
