Battle Royale: v. 5 by Koushun Takami
After their initial plan to take down The Program fails, Shinji Mimura and Yutaka Sato put their backup plan in motion. Having located all the supplies necessary to put together a crude bomb, the pair are all set to deliver their package right where it will do the most damage...the school which serves as The Program control center. The only problem is that the school is in a permanent danger zone. Shinji believes he's found a way around this. Or more specifically, above this. Meanwhile, Sho Tsukioka has never been what you would call a normal 9th grader. Flamboyantly gay, and damn proud of it, he believes the key to surviving The Program is to tail its likely winner, Kazuo. Kazuo, however, may have other plans. Finally, in what may be the most blackly comic Battle Royale vignette yet, Hiro Shimizu has seen her best friend turn on her, her other best friend murdered, and has now taken a bullet herself. While her wound may not be lethal, her bad luck, it would appear, just might be.
