The heroes visit the house of a young girl named Shun-Rey, who is waiting for the return of her boyfriend – the young apparition of a spirit. Sha Gojyo is surprised when he hears the name of this monster, Gee-Yen, which has the same as his missing brother-in-law. The townsfolk tell the heroes the monster that attacked humans in the forest looked like Gee-Yen. Shun-Rey runs to the forest.

The fortune-teller Chin-Ih-So approaches the heroes. Hakkai destroyed his family. Chin-Ih-So plots to cause Hakkai to go insane. Sha Gojyo and Goku are injured. Sanzo supports Hakkai in a silent battle with a dark, psychic world. Hakkai tries shake off a twisted illusion but, he is trapped by Chin-Ih-So's trick and suddenly attacks and wounds Sanzo. If Hakkai reverts back to himself, the heroes will quickly die.

Several monsters are missing. Yaone, a female warrior of Kogaiji, begins to investigate what is happening. Meanwhile, Sanzo and his three comrades find Tonpoo, an old friend of Sha Gojyo and Hakkai. Tonpoo tells the heroes he volunteered a militia called Fanron Troop, which consisted of humans tasked with hunting evil monsters. The same night, Yaone is captured by the captain of Fanron Troop when she sneaks into the camp.

Running out of food and tobacco, Sanzo and his followers come upon a lake with a beautiful, mirror-like surface—a saltwater lake. The local village has prospered as a salt producer and distributor. The numerous villagers are happy and lively.

Will the Sanzo party be able to defeat the War God Prince Nataku?
