They awake in a classroom in a small, vacated island, surrounded by troops, and wearing metal collars around their necks. A teacher, psychopathic sadist Kinpatsu Sakamochi, briefs the students: the class has been chosen to participate in the Program. The students are also given a time limit. If twenty-four hours pass without someone being killed, then all of the collars will be detonated simultaneously and there will be no winner. It is mentioned that only 0.5% of Programs end in this fashion. The students are issued survival packs and a random weapon/tool, and sent out onto the island one by one. While most of the students receive guns and knives, some acquire relatively useless items like boomerangs, dartboard darts, or a fork. Hiroki Sugimura finds a radar device that tracks nearby students, and Toshinori Oda receives a bulletproof vest.
