Hoshin Engi

Hoshin Engi (封神演義 Hōshin Engi), also known as Soul Hunter, is a Japanese manga series by Ryu Fujisaki. Hoshin Engi was inspired by an ancient Chinese novel Fengshen Yanyi. The story involves the Chinese mythology and history of China, in particular the last members of the In (Yin Dynasty aka Shang Dynasty) and the plot to overthrow them.

Plot
The story is set in legendary China. A beautiful female fox spirit named Dakki (妲己) is controlling the emperor Chu-o (紂王 Chū-ō) and the ruling In (殷) dynasty, and is using her power over him to do evil in the nation. An immortal-in-training named Taikobo (太公望 Taikōbō) is chosen by the great immortal sages for the Houshin Project (封神計画) — to seal away or destroy the evil demons that infest the world. In the course of his adventures, Taikobo 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.
