High schooler Nanami Momozono has quite a few problems of late, beginning with her absentee father being in such extreme debt that they lose everything. Downtrodden and homeless, she runs into a man being harassed by a dog. After helping him, she explains her situation, and to her surprise, he offers her his home in gratitude. But when she discovers that said home is a rundown shrine, she tries to leave; however, she is caught by two shrine spirits and a fox familiar named Tomoe. They mistake her for the man Nanami rescued—the land god of the shrine, Mikage. Realizing that Mikage must have sent her there as a replacement god, Tomoe leaves abruptly, refusing to serve a human. Rather than going back to being homeless, Nanami immerses herself in her divine duties. But if she must keep things running smoothly, she will need the help of a certain hot-headed fox. In her fumbling attempt to seek out Tomoe, she lands in trouble and ends up sealing a contract with him. Now the two must traverse the path of godhood together as god and familiar; but it will not be easy, for new threats arise in the form of a youkai who wants to devour the girl, a snake that wants to marry her, and Nanami's own unexpected feelings for her new familiar.

It has been six months since Yoshiki Tsujinaka's best friend, Hikaru Indou, went missing in the mountains and returned a week later with no recollection of what had transpired. Certain that it is not the Hikaru he knows who came back, Yoshiki finally asks Hikaru about it. Suddenly, "Hikaru" reveals his true monstrous form and begs Yoshiki to keep it a secret, as he does not want to kill him. Despite his paranormal nature, "Hikaru" seems almost innocent, full of childlike wonder and eager to experience the summer heat, the countryside, and all kinds of other things in a human body for the first time. And for Yoshiki, it matters little if "Hikaru" is a fake relying on stolen memories—as long as he never leaves again. As Yoshiki desperately clings to "Hikaru" in his intense grief, it becomes increasingly clear that something dangerous and supernatural may have descended from the mountains into their village.

The Republic of San Magnolia has been at war with the Empire of Giad for nine years. Though it initially suffered devastating losses to the Empire's autonomous mechanized Legions, The Republic has since developed its own autonomous units, called Juggernauts, which are directed remotely by a Handler. While on the surface the public believes the war is being fought between machines, in reality, the Juggernauts are being piloted by humans, all of whom are "86"—the designation given to the Colorata minority of San Magnolia. The 86 originally had equal rights, but were persecuted and scapegoated by the dominant Alba race and the Alba-supremacist Republic government to the point where Colorata were both officially designated and popularly considered subhuman. The 86 were not permitted to have personal names and were immured in internment camps in the 86th District (their namesake); all the while being forced to fight in the Republic's war with the Empire to receive better treatment. Major Vladilena "Lena" Milizé, an Alba noble and military officer in the San Magnolian military, is an outspoken activist against the grave mistreatment of the nation's Colorata minority, and the willful deception of the Republic government to the general public. She is assigned as the Handler of the Spearhead Squadron of the Eastern Front: an elite unit composed entirely of 86 veterans who have earned names. Led by their squad leader, Shinei "The Undertaker" Nouzen, the Spearhead Squadron is infamous among military officials. Its notoriety stems from the state in which its commanding officers are left: Handlers presiding over the squad have descended into insanity and some have gone as far as committing suicide. Lena, an avowed 86 sympathizer, gets to know the Spearhead Squadron in her time as head of the contingent. At same time, Lena and Shinei learn a dark secret: the Republic and the war with the Empire are not what they seem.
