The students, thinking that the truth about the fake video has finally come out, appeal to Hiiragi to release them. However, Hiiragi tells them that there is still a secret to be revealed, and issues the next challenge.
A few years later, on March 9, the students, who have moved on with their lives, visit the classroom again for the third anniversary of the death of Mr. Hiiragi.
Hiiragi takes Gunji hostage and brings him up to the rooftop. Hiiragi makes his final demand but is shot by a police sniper.
