Kokuhaku-sha

As a common worker, he once forced a starving beggar to carry heavy corn bags in exchange for food, and the beggar was crushed to death. The beggar's spirit vows revenge at the man's happiest moment, yet secretly helps him prosper until he becomes rich, marries and has a daughter. Fearing the curse, the man and a servant undergo surgery to swap faces; when the spirit returns, it mistakes the servant for him and kills the servant instead. The man later confesses to Rohan Kishibe that he is responsible for both deaths. Afterward, the spirits of the beggar and the beheaded servant remain with him, watching constantly for further wrongdoing.
