Battle Royale by Koushun Takami

smooth, hard wood. Was this what they called a boomerang? A weapon used for fighting and hunting in primitive tribes. An aboriginal village hunting hero might be able to knock down an ailing, sluggish kangaroo with this thing, but what use could it possibly have for them? Shuya sighed and returned it to Noriko's day pack.
    They finally stopped heaving like drown victims gasping for air.
    "You want some water?" Shuya asked.
    Noriko nodded and said, "Just a little."
    Shuya took out the plastic bottle from his day pack, broke the seal of the twist-off top, and sniffed the contents. He spilled some on his hand and licked it cautiously. Then after taking a sip, making sure he had no abnormal reaction, he handed it over to Noriko. Noriko took the bottle and only swallowed a small mouthful. She probably knew that water was precious. Each bottle only contained approximately one liter, and they'd only have two. Sakamochi said they had no access to telephones, but what about the water system?
    "Let me take a look at your leg."
    Noriko nodded to Shuya's request and stretched out her right leg, which had been tucked in under her skirt. Shuya took out the flashlight from his day pack. He cupped it carefully with the palm of his hand to prevent its light from leaking out and pointed it at her leg wound.
    The wound was on the outer calf. A section of flesh approximately four centimeters long and one centimeter deep had been scraped off. A thin stream of blood still flowed out of the ends of the pinkish flesh wound. It looked like she needed stitches.
    Shuya quickly turned off his flashlight and grabbed his sports bag instead of his day pack. He grabbed the bourbon flask and two clean bandannas he'd packed for the trip. He uncapped the flask.
    "This is going to hurt."
    "I'll be okay," Noriko said, but once Shuya tilted the flask and poured the bourbon to disinfect her wound, she let out a small hiss. Shuya pressed one folded bandanna onto her wound. He opened up the other one, folded it, then began wrapping it around her leg tightly like a bandage. This would stop the bleeding for now.
    After wrapping her leg, he pulled at both ends of the bandage tightly, tied them together, and mumbled,
    "Damn…"
    Noriko whispered, "You mean Nobu?"
    "Yoshitoki, Yoshio. Everyone and everything. I'm not into this. I am so not into this."
    As he moved his hands Shuya glanced at Noriko. Then he looked down and finished tying his knot.
    Noriko thanked him and tucked her leg in.
    "So Yoshio was the one who killed…" her voice was trembling, "…Mayumi?"
    "That's right. He was above the exit door. I threw the arrow at him and he fell."
    Now that he thought about it, Shuya suddenly realized he hadn't taken care of Yoshio. He'd instinctively assumed Yoshio would remain unconscious for a while, but for all he knew Yoshio might have woken up immediately afterwards.
    Which meant he might have taken his bow gun, climbed up on the roof, and continued his slaughter.
    Was I being too naive again? Should I have just killed him over there?
    With this thought Shuya checked his watch under the moonlight. The old, domestically manufactured Hattori Hanzo limited-edition diver's watch (along with most of his belongings, it had been donated to Shuya through the orphanage) read 2:40. Everyone might have left by now. At most there were only two or three students left, regardless of Yoshio Akamatsu's state. Shinji Mimura had already…Shuya was nearly certain Shinji could easily escape Yoshio...By now he'd already left too.
    Shuya shook his head. Now he felt foolish believing they could unite against their situation.
    "I never thought someone like him would actually try to kill everyone else to survive. I understand the rules, but I didn't think anyone would actually participate."
    "You might be wrong about that though," Noriko said.
    "Huh?" Shuya looked into Noriko's face, too dark to discern under the moonlight.
    Noriko continued, "You know how Yoshio was always timid. I think he
