A Touhou parody of Battle Royale, a novel and later, a film. In the story, because of overpopulation and a failing education system, the Japanese government initiated a program to reduce population by taking a group of kids to an isolated location, providing them with weapons, and having them fight to the death. Each person is wired with explosives, and all but one person must be eliminated within 3 days, else all participants are killed.
