Variation by Hirabayashi Shunichi, with a few adjustments by MN.
Make a list of fears in advance, to save time. From the list, players vote for the top 10 fears that they have. Of course, they can add another words not on the list, but the number of fears should be the same as the number of demons.
Divide the participants into two groups. One group is the people, the other is the Demons. Each Demon will choose one fear to represent, keeping this secret from “the people.” The Demons will draw masks that somehow express – without words or symbols – the fear that they represent.
