Shinji Mimura

In the Program, Mimura is shown to be a intuitive and intelligent student. He was the only student to figure out that there were microphones in the collars (although this does not stop them from still talking about their plans). He is also a lethal hacker. Along with his friends Yutaka and Ijima, Shinji managed to hack the computer system with a "Third Man" hacking code, making the collars stop working for 15 minutes. Their plan was that while the systems were offline and the danger zones were cleared they would drive a truck filled with explosives and molotovs that they all made in the 15 minute gap into the school to blow it up in order to kill Kitano and the soldiers.
