Hokaibo, a depraved monk, lives amidst the din and bustle of the great city of Tokyo. Pretending to raise funds to rebuild a temple bell, Hokaibo actually spends what money he can collect pursuing women. His mind is turned not to the pious thoughts suitable to a monk, but to fantasies of a life of luxury indulging in his favorite food: drink and pleasures of the flesh.
Uncontrollable desire and greed lead him to spying, deceit, theft, and even murder. Hokaibo's adventures end with his own death; his soul merges with the ghost of a long-suffering princess, creating a powerful and dangerous creature who terrorizes the people of Tokyo.
