Having narrowly escaped their encounter with the brutal Kazuo, Shuuya and Hiroki tend to their injuries while other players take center stage. Shinji Mimura and Yutaka Sato have quietly assembled a bomb for the express purpose of destroying the "school" that serves as The Program's command center. Everything is in place, all they need do is deliver it, but in the world of Battle Royale, nothing is ever so simple. An encounter with another classmate causes Yutaka to question his trust in Shinji, but the real trouble arrives in the form of one Kazuo Kiriyama. Having lost Shuuya and Hiroki, Class B's most feared student is angry and frustrated, a dangerous combination for a man with a machine gun. With the element of surprise on his side, Shinji and Yutaka have little chance of seeing the morning, but maybe, with a little luck, they can take the murderous Kazuo with them.
