It's only natural that employees have started to quit. Nezumi-Otoko, who happened to be nearby, proposed the use of yōkai. The Kappas from the Tono mountains are hard workers, and the president is pleased that he could secure such employees with a cheap salary of three cucumbers an hour. The Kappas are also very satisfied with the all-you-can-eat cucumber workplace. However, the Kappas gradually began to get suspicious that they were being exploited. Finally, they stood up and demanded their rights!
