However, when the tyrannical Zoble Empire resurrects a demon, the misfit crop of gods are called to the battlefield against their natural enemy once more.

Ichirou Inuyashiki is a 58-year-old family man who is going through a difficult time in his life. Though his frequent back problems are painful, nothing hurts quite as much as the indifference and distaste that his wife and children have for him. Despite this, Ichirou still manages to find solace in Hanako, an abandoned Shiba Inu that he adopts into his home. However, his life takes a turn for the worse when a follow-up physical examination reveals that Ichirou has stomach cancer and only three months to live; though he tries to be strong, his family's disinterest causes an emotional breakdown. Running off into a nearby field, Ichirou embraces his dog and weeps—until he notices a strange figure standing before him. Suddenly, a bright light appears and Ichirou is enveloped by smoke and dust. When he comes to, he discovers something is amiss—he has been reborn as a mechanized weapon wearing the skin of his former self.

However, the origins of these strange powers remain unclear. Who was the mysterious figure at the site of the explosion, and are they as kind as Ichirou when it comes to using this dangerous gift?

Sentenced to death, ninja Gabimaru the Hollow finds himself apathetic. After leading a blood-soaked life, Gabimaru believes he deserves to die. However, every attempt to execute him inexplicably fails. Finally, Sagiri Yamada Asaemon, a fledgling member of a famed executioner clan, is asked to take Gabimaru's life; yet Sagiri makes no move to kill him as requested.

Though unaware of the numerous dangers ahead, Gabimaru decides to accept the offer—alongside ten other death row convicts—in hope that he and his wife may finally live in peace.
