In the nuclear-scorched wasteland of the year 199X, a young man named Nobu is desperately seeking any form of stable employment. He stumbles upon a promising opening with the most dangerous employer in the post-apocalyptic world: the army of the fearsome conqueror Ken-Oh, also known as Raoh. The official tagline promising three meals a day, company housing, and no experience necessary proves too good to pass up, and Nobu quickly signs on. He soon discovers that his new job as a low-ranking grunt comes with an extremely high mortality rate, where the number of soldiers who die on the job exceeds the number of applicants for the position.

Shifting the focus away from legendary martial artists and epic battles, this darkly comedic spin-off centers on the daily struggles of the disposable infantry trying to survive their shifts. Nobu is joined by fellow grunts Zaku and Buzz as they navigate a workplace filled with absurd dangers, incompetent middle managers, and the constant threat of being on the receiving end of a fatal secret technique. The narrative unfolds through short, fast-paced episodes that parody the iconic moments and tropes of the classic manga, portraying the grandiose schemes of Ken-Oh's army from the ground-level perspective of the unlucky soldiers who have to carry them out. The series features appearances from various memorable minor characters of the original universe, such as Uighur, the warden of the prison city Cassandra, and the fanatical Holy Emperor's Army soldier known for shouting "Disinfect the filth".

As the series progresses, Nobu and his companions encounter a parade of uniquely colorful zakos, the Japanese term for small-fry or underlings. The narrative arcs follow their ill-fated assignments, from patrolling the wasteland disguised as old ladies to attempting to enforce Ken-Oh's brutal will on villages, all while dodging the god-like warriors who routinely decimate their ranks. The show maintains a satirical look at corporate work culture through the lens of a violent dictatorship, exploring themes of survival, camaraderie, and the absurdity of being a nameless villain in someone else's heroic saga. The anime is produced by studio Do-Raku, with Hiro Shimono voicing the lead role of Nobu, and premiered in January 2026 as an adaptation of Hiroshi Kurao's manga spin-off of the same name. The opening theme is Blacker Co., Ltd. by Itsuka, with the ending theme Elegy of the Enemies performed by The Canbellz.
