Two of Oma's workmates, Ryuichi Murakami and Koji Kawamata, are embezzling money from the company. To do it, Murakami seduced Yamamoto, a woman who works in the company accounting department. When an investigation about the case starts and a rumor that Yamamoto is the culprit starts to be spread, Yamamato is found hung in a rope. The police consider it as a suicide, but Oma, as the Judge of the Darkness, appears before Murakami and charges him for Yamamoto's murder.
