One day Shin-chan on his way back found a ball near a river and brought it home. Himawari saw that ball and swallowed it as she loves shining things. Later it was known that it was a mysterious ball that belonged to Devil Jack and two gangs for which they were fighting with each other for getting the ball. It was considered that they could win the world with that ball by releasing the Devil Jack. Himawari was kidnapped by the king Jed, but later she was released. Devil Jack was accidentally released by Shin-chan.
