Battle Royale - Plot

Plot

Battle Royale takes place in 1997 in an alternate timeline—Japan is a member region of a authoritarian state known as the Republic of Greater East Asia (大東亜共和国?, Dai Tōa Kyōwakoku). Under the guise of a "study trip", a group of students from Shiroiwa Junior High School (城岩中学校, Shiroiwa Chūgakkō?) in the fictional town of Shiroiwa, in Kagawa Prefecture, are gassed on a bus. They awaken in the Okishima Island School on Okishima, an isolated, evacuated island southwest of Shodoshima (modeled after the island of Ogijima). They learn that they have been placed in an event called the Program. Officially a military research project, it is a means of terrorizing the population, of creating such paranoia as to make organized insurgency impossible.

The first Program was held in 1947. Fifty third-year junior high school classes are selected (prior to 1950, forty-seven classes were selected) annually to participate in the Program for research purposes. The students from a single class are isolated and are required to fight the other members of their class to the death. The Program ends when only one student remains, with that student being declared the winner and receiving a government funded pension. Their movements are tracked by metal collars, which contain tracking and listening devices; if any student should attempt to escape the Program, or enter declared forbidden zones (which are randomly selected at the hours of 12 and 6, both a.m. and p.m.), a bomb will be detonated in the collar, killing the wearer. If no one dies within any 24-hour period, all collars will be detonated simultaneously and there will be no winner.

After being briefed about the Program, the students are issued survival packs that include a map, compass, food and water, and a random weapon or other item, which may be anything from a gun to a paper fan. During the briefing, two students (Fumiyo Fujiyoshi and Yoshitoki Kuninobu) anger the supervisor, Kinpatsu Sakamochi, who kills both. As the students are released onto the island, they each react differently to their predicament; beautiful delinquent Mitsuko Souma murders those who stand in her way using deception, Hiroki Sugimura attempts to find his best friend and his secret love, Kazuo Kiriyama attempts to win the game by any means necessary (stemming from his lack of ability to feel human emotion due to a partial lobotomy caused by a car crash while in utero) and Shinji Mimura makes an attempt to escape with his best friend, class clown Yutaka Seto.

In the end, four students remain: protagonist Shuya Nanahara, Noriko Nakagawa (the crush of Shuya's best friend), Shogo Kawada—a survivor of a previous instance of the Program—and antagonist Kazuo Kiriyama. Following a car chase and shoot-out between Kazuo and the main characters, Noriko kills Kazuo by shooting him, but to absolve the quiet and naturally good-natured Noriko of any guilt, Shogo then shoots Kazuo, claims he is in fact responsible for Kazuo's death, and then takes his two partners to a hill. After telling Shuya and Noriko that he will kill them, Shogo shoots in the air twice, faking their deaths for the microphones planted on the collars. He then dismantles the collars using information he had previously hacked into the government servers to obtain. Shogo boards the winner's ship, as do Shuya and Noriko, covertly, a short while later. On the ship, Shogo kills Sakamochi and a soldier, while Shuya kills the other soldiers on board. Shogo tells Shuya how to escape, succumbs to his wound from the battle with Kiriyama and dies. The two remaining students return to the mainland and attempt to travel to find a clinic belonging to a friend of Shogo's father. From there, they make plans to escape to the U.S., facing an uncertain future as they run from the authorities who have spotted them as they try to board a train.
