The guys are getting ready for the ghost-catching game, which is supposed to take place in the arena. The guy with the cropped hair is the one who's mobilizing the troops, and he's got a special shock absorber that he uses to keep people from getting caught by ghosts. Everyone is ready to go, but they need to make sure they don't get caught by a ghost that's not supposed to catch people. Whoosh, whoosh, what's going on? It's a game of "ghost-catching" , and the only way to catch a ghost is to kill it. The guys need to find out what the ghost is, so they can kill it or be seen by it. They need to figure out how many ghost servants there are, and how they're supposed to handle the whole thing.
