Plot
The story is set in legendary China. A beautiful female fox spirit named Dakki is controlling the emperor Chu-o and the ruling In dynasty, and is using her power over him to do evil in the nation. An immortal-in-training named Taikōbō is chosen by the great immortal sages for the Houshin Project — to seal away or destroy the evil demons that infest the world. In the course of his adventures, Taikōbō gathers other powerful companions and sets out to seal away the demons and eventually destroy the fox-spirit Dakki.

There are significant plot differences between the novel, the manga series and the anime. In the novel adaptation by Ryu Fujisaki, Houshin Engi follows Taikōbō on his mission to rid the Ningenkai of the evil immortals that have resided there.
