Королевская битва 2

Three years have passed since the infamous Battle Royale massacre, and one of the kids that survived the bloody game — Shuya Nanahara — has set up a terrorist group, declaring war on Japan's adults. A new game is established by the government, and the 42 randomly-selected school kids are this time given the task of storming the terrorists' island fortress to kill Nanahara within three days — or they themselves will be terminated.
