A decade after the blood-thirsty Battle Royale, another gore game has begun. The Japanese government created an absurd game for high school students one day. The rule: only the strongest survive. For Fujiwara, everything seems to be going well – he is doing well in school, he is good looking and also he is a good fighter. One day, he is suddenly attacked by a group of students without any provocation. He then found out that there is this mysterious violent game that is being spread through the mobile phone in the school. Students who played the game became hypnotized and will begin to fight senselessly. Fujiwara fought and finally discovers the terrifying secret.
