Battle Royale: v. 6 by Koushun Takami
Having recovered from her fever, Noriko is now ready to travel, but her trip is cut short by the powerful Hiroki. Confronted by Shogo, the two come to blows until Shuuya intervenes. Inviting Hiroki to join them, the young martial artist briefly considers it, but ultimately goes his own way, revealing that he's searching for Kyoichi Motobuchi. Making plans to rejoin the alliance as soon as he finds Kyoichi, Hiroki departs just as the alliance finds itself under attack. When it's discovered that the attacker is Kazuo, Shuuya agrees to distract him while Shogo and Noriko flee. It's a sacrifice that will cost him dearly. Shuuya survives, but just barely. Having caught several rounds from Kazuo's machine gun, it's only through the interference of Hiroki that Shuuya escapes with his life. Meanwhile, Shinji and Yutaka are on the verge of completing their plan to take out the "school," when the bumbling Yutaka loses an integral piece of equipment. With his temper slowly rising, how will the frustrated Shinji react?
