Humans and katawara are at war, but there are those on each side who join forces. Tama is a fox spirit who loves humans, while her sendou brother, Jinka, despises them. Together, they use the power of spirit transformation to defeat the monstrous katawara and put an end to the evils of this chaotic age. What destiny awaits the duo at the end of their journey?
The chaotic aftermath of a confrontation between Jinka Yamato and Yazen results in the power dynamics between the magically gifted katawara and humans being turned upside down. As the news of the downfall of dangaishu—the katawara-hunting monks led by Yazen—spreads across the country, rogue groups of katawara start to form, worsening the already-fragile relationship between them and humanity.
Having lost faith in his abilities, Shinsuke Hyoudou now spends his time heavily drinking in the company of Senya. Senya indirectly causes the death of the father of Tsukiko, after a surprise attack of a local god gone berserk.
Despite this, Tsukiko holds no grudge against Senya and is determined to become Shinsuke's disciple no matter what. Although Shinsuke refuses to become Tsukiko's sword instructor, he reluctantly agrees to let her travel with him and Senya. While the unlikely trio heads towards their next destination, Tama Youko continues her journey to find the trail of Jinka.
