Twenty years ago, the fascist government of the Republic of Greater East Asia seized control of Japan. To terrorize citizens and crush any possibility of rebellion, the government established Program 68, a brutal military program in which Japanese high school students were sent to a remote island and forced to kill one another—the Battle Royale. After being banned for two decades, Program 68 has returned, now under the direction of a sinister government artificial intelligence. The troubled and misbehaving students of Daitoa Academy's Class F have been selected, armed, and divided into squads, and must now fight each other to the death. Friendships and loyalties will be tested, and only the strongest will survive.
