A demonic reincarnation of a Japanese general from the 10th century appears in the early 20th century Tokyo with a mission to destroy the blooming city.

In 1945, after the horrific fire-bombings of the Pacific War levels Japan to the ground, the government consults spiritual psychics to aid them in winning the war. Unfortunately, the souls' resentment and agony of the victims culminate together to revive the evil Onmyoji, Yasunori Kato. Only a young, psychically imbued priests' apprentice will dare fight the evil magician.
