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]

The Sailor Guardians and their leader, Sailor Moon, continue their duty of protecting Earth from any who would dare cause it harm. However, Sailor Mars' apocalyptic visions and the appearance of two new guardians—Sailor Neptune and Sailor Uranus—signal that a new battle will soon begin. These newcomers seek three Talismans that are inside the Pure Heart Crystals within human beings. Once brought together, these objects form The Holy Grail, a magical relic with extraordinary abilities. They want to use the Grail to save the world, but an evil organization known as the Death Busters seeks its power for their own desires. The removal of a Talisman from a person's Heart Crystal will cause their death, something that Uranus and Neptune see as a necessary sacrifice to form the Grail, while Sailor Moon and her group deem it unforgivable. But can any sacrifice be worth the cost if it saves the lives of the entire human race? [Written by MAL Rewrite]

Due to his love for small, cute things, Souta Takanashi cannot turn childlike Popura Taneshima down when she recruits him to work for Wagnaria, a family restaurant located in Hokkaido. Takanashi takes particular joy in doting on the older Popura, which only fuels her complex over how young she looks. He also quickly learns he must stay on his toes once he meets the rest of his colleagues, including the katana-wielding floor chief Yachiyo Todoroki, the intimidating head chef Jun Satou, the dangerously well-informed and subtly sadistic sous chef Hiroomi Souma, the adamantly lazy manager Kyouko Shirafuji, and the waitress Mahiru Inami who has a "painful" fear of men. Powered by an eccentric cast, Working!! is a unique workplace comedy that follows the never-dull happenings within the walls of Wagnaria as Takanashi and his co-workers' quirky personalities combine to create non-stop antics, shenanigans, and hilarity.
