Crayon Shin-chan: The Storm Called! The Adult Empire Strikes Back

About the story

One day, a new amusement park called the Twentieth Century Expo suddenly opens near Kasukabe, where Shin-chan lives. Old twentieth-century television programs and films play everywhere; everything recreates bygone days. Every adult who visits becomes absorbed in nostalgia, while the children find it completely uninteresting. What Shin-chan never expects is that once his parents enter the park, they stop caring about anything else and remain lost in the past. All the town's adults go there, leaving only the children behind! Who is behind this plot, and can Shin-chan and his friends stop it?
