In the middle of the night, the school's gym is abuzz with activity. Everyone is trying to figure out how to get rid of the disc-keeper, who is responsible for keeping track of everyone's movements. The other students are trying to find a way to stop him, too, but they can't find any way to do it. The disc-keepers, however, can only attack one person at a time, and the other students cannot attack anyone at all. This is the first time we've seen this rule in action, so we're not sure how it's supposed to work, but it works pretty well. It's not like they're going to be able to do anything about it, though, because the walls around the gym are so high that they'll have no way of stopping the other players from hitting them. The students are so excited about the upcoming battle that they start to clap and yell at each other.
