One after another, Kitarō and his friends get attacked. Medama-Oyaji says that Yūta is the cause...!?

If this continues, she will lose her life. Can Kitarō get rid of the yōkai that is haunting Masae...?

A company president is conversing with his subordinate at a bar, saying "people who believe in yōkai are just making excuses because they are weak."

In order to get home, he and his subordinate board a special train. Eventually, The president begins to realize that the train is traveling on a different route than usual.

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.
