Shinichi Sanada, a student at Ibuki Academy, attempted suicide by jumping off a building. The reason for his suicide was school bullying. Student council president Hayato Fujiwara knew that Sanada was bullied and thought that he was a weak person and that it was natural for him to be bullied. Fujiwara was suddenly chased on the street. The bad group headed by Kenji Todoroki was chasing him. Fujiwara not only cleverly shook off the pursuers, but also caught Masashi Nakajima who was about to attack him. Under Fujiwara's questioning, Nakajima revealed the reason for the crime. He registered on the school's underground website and participated in a dangerous game. He had to do this to get points. Everyone who joined the game entered their personal information. If they could grab someone else's mobile phone and send text messages, they could get points. Using the points, they could delete their own information, and the extra points could be exchanged for huge amounts of cash. However, once the points reached zero, it was "GAME OVER", and personal secrets were exposed. Fujiwara guessed that Sanada's suicide was related to this game, and decided to participate in the game himself to find out. Chiori Kinoshita was forced to join the game by someone else logging into the website and entering information. When she was in danger, Fujiwara saved her. Fujiwara, Kinoshita and other game participants were attacked by point hunters. Shinichiro Kamiya suddenly appeared and persuaded everyone to take a bus to a safe place. Fujiwara did not trust Kamiya. He felt that collective action was prone to sniping, so he got off the bus with Kinoshita. Assassins appeared one after another. Can Fujiwara survive and become the winner of the game?
