A prison island where criminals are isolated from society. Yoshioka repeatedly clashes with the guards, and after Kubota is captured and badly injured, the two are thrown into solitary confinement and beaten relentlessly. Amid the violence, Oogami (Yu Matsuda), the hospital’s chief, orders that they be treated. The next day, Yoshioka and thirty other inmates are taken to a classroom. Standing at the podium is the island’s new owner, Sakata (Daisuke Nagakura), who delivers a chilling announcement: “Today, you’re all going to kill each other.” A deadly free-for-all among young offenders begins. The long-awaited second chapter of the series.
