Shin-chan and his parents go to watch sumo wrestling live. Misae cheers for Mainoumi, while Shin-chan cheers for Onishiki. Eventually, Mynomimi wins, but Shin-chan objects the decision and goes inside the ring. When Misae goes to get Shin-chan, Yokozuna lifts her up on his shoulder, and Shin-chan also climbs. Hiroshi clicks pictures of them. At the end, they get kicked out of the stadium.
