A note about chapter 87 (Child's Play): "Daruma-san has fallen" is from a children's game which is similar to the game "red light green light" (popular in the U.S.). One person closes his or her eyes and calls out "daruma-san has fallen!" That person then turns around to look at the other players. If he or she catches any of them moving at that point, they lose the game. The goal of the other players is to reach the person without being caught moving.
