One day, high school student Shunsuke Ohta comes across a man that looks exactly like himself, who commits suicide at a train station. The next day, Shunsuke is abducted on his way home from school. When Shunsuke wakes up after that, he finds himself inside of a cage. There, various torturers gather and compete to see who can make their target confess their secrets the fastest in the "Torture Tournament." Shunsuke's battle as the "White Prince" against the "Black Moon" begins!

Three years have passed since the bombing of a classroom by a boy who rarely came to school. Now, the seven survivors of that incident have gathered in that classroom. One of the survivors, Takumi Shindou, informed the other survivors that one of them was responsible for giving the bomb to the culprit. With those words, the search for the accomplice began. At the same time, a female student went to a private high school in Tokyo. "All of you will die with me," she said, with a bomb wrapped tightly around her body… Thus continued a chain of terrorism by bullied students, striking fear into classrooms all across the nation!
