Long ago in the nine provinces of Kyushu, a calamitous event was prophesied to take place: falling comets would exhaust the spiritual energies of both the heavens and the lands and thus bring about an age of chaos upon the world. But contrary to the prophecy, the comets passed by with no calamity taking place. At the same time, as if touched by the phenomenon, a boy was born in a remote village of the Sokei region by the name of Ouriku. Twelve years later, as the memories of the event have faded from people's minds, the Reikenzan clan—one of the five supreme sects of the nine provinces—decides to hold an examination in order to gather the most talented individuals fit to become disciples and eventually sages. Hearing about this news, Ouriku and his servant Ouchou head toward the site, unaware that the organizer Oubu, despite her elegant appearance, is infamous for being extremely irresponsible and carefree; hence, making the trials in the examination unpredictable. Reikenzan: Hoshikuzu-tachi no Utage follows the story of Ouriku as he journeys through these trials to become a powerful sage. [Written by MAL Rewrite]

The story takes place in Japan. The year is 2030 and Earth has been completely overrun by a viral disease named "Gibia" that turns infected people into various different monsters, based on their age, sex, and race. A samurai and a ninja from the early Edo period travel together through time and arrive in a ruined Japan to aid a professor working on a cure for the virus. Together, they fight countless Gibia monsters, outlaws, and other fierce foes on their journey to save mankind.

A young girl named Zuru sets out on an expedition through a post-apocalyptic city controlled by machines in a desperate hunt for food. Things go awry when her team accidently triggers the city's AI defense program called the Safeguard. Attacked by the machines, her companions are on the verge of being annihilated when a mysterious man named Killy arrives and exterminates the hostile units.

Despite his heroic intervention, Zuru is hesitant to trust Killy and questions his motives. He reveals to have come from thousands of levels below the city in order to find humans possessing the Net Terminal Genes—a trait that would allow humans to regain control of their civilization and shut down the Safeguard. After hearing his story, Zuru and the rest of her team join Killy and embark on a journey in search of the Genes that could prove to be mankind's last hope of survival.
