Setting the wire across sector G-7 where the school was turned out to be a hassle. First, Shinji tied the end of the wire to the tip of a tall tree behind the rock they’d climbed on. Then he took the other end and began walking between the trees, but then a gust in the upper region of the sky acted up, so guiding the garbage-bag balloons proved to be difficult. There were at least ten occasions where he had to climb up a tree to loosen the wire. On top of that, given how the enemy could be anywhere in the dark, he had to worry about Yutaka, so the endeavor ended up exhausting him.
But he’d managed to set the wire after a full three hours, when he heard the gunfight. It was past 11 p.m. He heard an explosion as well, but he couldn’t afford to get involved, so he hurried back to the farm coop with Yutaka. By then the gunfire had ceased.
Finally Shinji began building the electric detonator, but this also turned out to be difficult. He didn’t have the proper tools, and furthermore the device required a delicate balance. Electric current had to run through the device at the moment of impact against the school, but at the same time he had to make sure it wasn’t so sensitive it’d be ignited in the middle of the rope cable by, say, a bump or knot in the rope.
But somehow he managed to build it, using a motor (which he removed from an electric razor) instead of the detonator for the test. It was right when he began testing, in other words, only moments ago, that the midnight announcement was made. The only one who died was Hirono Shimizu (Female Student No. 10), whom Shinji saw immediately after the game began. He thought it might have been a result of that intense gun battle, but in any case Sakamochi had announced something far more urgent, at least to him and Yutaka. Sector F-7, which included the cliff rock they’d climbed up on to survey the school, was designated to be a forbidden zone as of 1 a.m.
No wonder Yutaka was so impatient. If they couldn’t enter that area then all their preparations would amount to nothing. It would be the end for them. He didn’t want to be in the situation of, after a clever play, being just one move away from checkmate only to fall into a fatal trap.
Shinji quickly pulled out the electric detonator from the tube chained to his knife. He connected the two cylinders—their dull metallic exterior shone in the dark—and peeled off the insulation from the lead wire. Then using tape, he first secured the small plastic spring serving as the electrical switch, then took the end of the lead wire extending from the detonator and tied it to the wire from the charge device. He taped the connection over and over so it would be completely secure. Then next to the battery he installed a condenser circuit board taken from the flash component of a camera. In order for the detonator to be absolutely reliable, he needed a high voltage output. He connected the wires to this device as well. To prevent any accidental detonation, he decided he would work on the remaining wire from the electric detonator at the top of the mountain, taping the exposed end of the wire to the side of the battery.
“All right.”
Shinji stood up, and then put the completed detonation device in his pocket.
“Let’s hurry. It’s time.”
Yutaka nodded. Just in case, Shinji tossed his equipment, including the electrical pliers and extra lead wire into his day pack, and then lifted several piles of rope they had divided up onto his shoulder. He looked down. There was a gas can filled up with a mixture of gasoline and ammonium nitrate. To add oxygen, he stuffed in insulation material filled with air and folded in pleats. The opening was shut with the lid, but next to it another rubber lid functioning as the detonator holder was tied to it with a plastic cord dangling from the handle.
Then he looked at his watch. It was 12:09. They had plenty of time.
Okay then. He was trembling from excitement. It took a lot of effort, but now they had everything they needed. They would connect all the ropes they had, tying one end to a tree in H-7. Then they would tie the other end of the rope to the end of the fishing wire secured by the weight of a rock. They would unravel the rope and leave it there and then go around the school, going up the mountain into F-7. He would take the wire tied to the top of the tree and reel it in immediately. The rope stuck to the wire would then come to them. He would proceed to attach the pulley to the gas-can gondola with the detonation device and thread the rope through it. Then he would stretch the rope taut with one swift motion and secure it to a tree. Then the rest is… party time, dude. Have fun! Here we go! Make it happen!
Once they had done some damage to the school’s computer, or its electrical current or wiring, Sakamochi’s staff would suspect a system failure, no, given the power of explosives here once the entire computer… no, in fact half the school was blown up, then they would take the tire tubes they’d already hidden behind the rock in F-7 and run towards the western shore, escaping by sea as planned. If they could mislead the government by sending a false SOS signal using their transistor radio and get to the next island, Toyoshima, in less than a half an hour as calculated, then they would take a boat. (He had experience with a motor boat. He was really appreciating all the wisdom his late uncle had imparted.) Then they would probably escape into Okayama, hopefully landing on an obscure shore, and then they’d be fine. They could take a freight train heading to the countryside. Or they would furnish themselves with a car passing by. After all, he had a gun. Carjack. Nice.
Shinji looked down at the Beretta M92F tucked into his belt. He was planning on slipping through by misleading the government, but just in case they were found at sea, he’d filled several Coke bottles with his special ammonium nitrate-gasoline mixture and stuffed them into his day pack. But without a detonator they were basically just Molotov cocktails. If they were detected, it would be best to swim toward the guard ship and get on board to fight. If all went well they could get their hands on the enemy’s weapons, and if they could operate the ship, it could provide their means of escape. But he would have to be a good shot to accomplish this.
He was a little concerned. He’d been running all over the island with his Beretta, but come to think of it, he hadn’t fired it once. And even his uncle didn’t have a gun, so he’d never learned how to use one.
But Shinji shook his head. The Third Man, Shinji Mimura. No prob. The first time he held a heavy basketball and tossed a free throw, the ball swooped right through the basket.
“Shinji.” Yutaka called him.
Shinji looked up. “Are you ready?”
“No…” Yutaka said pitifully. And then he nervously wrote something on the memo pad.
Shinji read it under the moonlight by the window. It read, I can’t find the pulley.
He glanced at Yutaka. For all he knew he might look really mad. Yutaka suddenly drew back.
Yutaka was in charge of half of the rope supply and the pulley. Ever since Shinji took the pulley from the well, Yutaka had been in charge of it, bringing it over here and putting it somewhere.
Shinji put his bundles of rope and day pack down again. He began searching the area on his knees. Yutaka did the same.
