Battle Royale 2: Blitz Royale

A group of middle school students from Shikanotoride Junior High School are selected to take part in a deadly competition on an island, where they must fight until only one remains. The manga centers on Makoto Hashimoto, identified as Girl #10, who worries about her class being chosen for "the program," a secret event requiring students to kill one another. Encouraged by her best friend, Itou Yamamoto, and her mother, she prepares for the possibility. Her concerns appear unfounded when it is announced that fifty such programs have already taken place in the past year, making it highly improbable that her class will be selected.
