If I recall correctly some people actually put the "Demons Out" thing in Japan, someone taking the role of the "Demon" (well it would be more like Ogre, since they mean Onis) and people throwing the pellets thingies to them.
Of course, in this scenario Akyu seems to be doing the role against her will.
