After the previous Godzilla attack, a miniature arms race ensues to collect his cells. Concerned over Godzilla's possible return, the Japanese government uses the cells to create a new bio-weapon, ANEB (Anti-Nuclear Energy Bacteria). They seeks the aid of geneticist Genshiro Shiragami, who's experiments result in a new mutation.

The year is 1945. After the horrific fire-bombings of the Pacific War levels Japan to the ground, the government decides to consult spiritual psychics to aid them in winning the war. Unfortunately, the resentment and agony of the souls of the fire-bombing victims culminate together to revive the evil Onmyoji, Yasunori Kato. Only a young, psychically imbued apprentice of the priests will dare fight against the evil magic user. However, can this lone man possibly contend with Kato's overwhelming power?
