BattleRoyle

Battle Royale takes place in an alternate timeline; according to the book’s prologue, Japan is a police state, known as the Republic of Greater East Asia . From time to time, fifty randomly selected classes of secondary school students are forced to take arms against one another until only one student in each class remains. The program was created, supposedly, as a form of military research, though the outcome of each battle is publicized on local television. A character discovers that the program is not an experiment at all, but a means of terrorizing the population. In theory, after seeing such atrocities, the people will become paranoid and divided, preventing an organized rebellion. Under the guise of a ‘study trip’, a group of students from Shiroiwa Junior High School , a junior high school operated by the fictional town of Shiroiwa , are corralled onto a bus and gassed, only to awaken in a school on an isolated, evacuated island, wearing metal collars around their necks. After being told about the program, the students are issued survival packs (along with a random weapon or a tool) and sent out the island one by one. While most of the students receive guns and knives, some students acquire useless items like boomerangs, some common dartboard darts, or a fork. In some cases, instead of a weapon, the student receives a tool. To make sure the students obey the rules and kill each other, the metal collars around their necks track their positions, and will explode if they linger in a ‘Forbidden Zone’ or attempt to remove the collars. The Forbidden Zones are randomly chosen areas of the map that increase in number as time goes on, re-sculpting and shrinking the battlefield and forcing the students to move around. The collars secretly transmit sound back to the organizers of the game, allowing them to hear the students’ conversations, root out escape plans, and log their activities.
