Seventeen years ago, a baby boy was abandoned in front of the daycare center. In his small hand was an old die with a tiger sitting on the second dot. It was a mysterious ivory die made with prayers in ancient India. Now a high school student, Sho works at the "Niko Niko Garden" daycare center after school. One day, a small problem occurred at Niko Niko Garden. The mother of Shin-chan, a child attending kindergarten, hasn't come to pick him up.

When Choji hears about it from his granddaughter Minako, he worries, "That's not a game for decent people"
