This work by Hiro Ando is from the Schoolgirl Series, which is based on characters from Koushun Takami's 1996 novel, Battle Royale (バトル・ロワイアル). The novel takes place in a fictional fascist Japan, where a government sponsored program, "Battle Experiment No. 68," forces fifty randomly chosen junior high students to fight to the death each year on a remote island. When it was published in 1999, it was a bestseller, despite its violent content; it went on to become a manga series in 2000 and was adapted to film by the great Japanese genre director Kinji Fukasaku.

Still from Battle Royale (2000)
