Hiroki grimaced from the sudden surprise. He got up, crouched, and then closed the door and locked it.
The gunfire sounded familiar. It was the sound he'd heard before and after that incredible explosion. After he escaped Toshinori Oda, he heard the sound of gunfire behind him...in other words it was whatever killed Toshinori Oda. It was also the gunfire he'd heard when Yumiko Kusaka and Yukiko Kitano were killed. He'd heard the gunfire several other times. It all came from "that classmate." Like Hiroki, the assailant had probably come here after hearing gunfire. Or maybe the student was here to kill the assailant who'd killed Yukie Utsumi's group. Or maybe—the assailant himself was returning.
Kneeling down on the floor, Hiroki reached around his back and gripped his gun with his left hand. He'd found the bullets in the day pack Mitsuko left behind, so it was now fully loaded, but he couldn't find an extra magazine. Maybe Mitsuko had put it in her pocket. Colt Government .45 Single-Action Automatic. Seven rounds in the magazine, plus one in the chamber. He couldn't afford to reload the bullets individually. The moment he did he'd be wasted by the assailant's machine gun or any other gun on him or her.
His back against the wall, Hiroki looked at the kitchen where the girls' corpses were. Unfortunately, the windows were sealed with planks from the inside. It would take too much time to tear them off and escape. He looked over at the door leading to the tower. No, that was impossible. It was too high for him to jump off the top of the lighthouse. It would be insane. He'd end up sun bathing right next to Yuko Sakaki. No, wait...what was this "someone" trying to do? Was he tiptoeing behind the door, approaching, or was he taking his time waiting for Hiroki to come out? No, he had to be in a rush too. He had to get rid of Hiroki before he might be shot from behind by someone else arriving as a result of the gunfire—
Hiroki was right. The wood around the doorknob was blown to bits. (In fact, several of the bullets exiting the door tore off the shoulder and side of Chisato Matsui, who was lying directly in front of the door.)
The door crashed open.
The dark figure leaped into the room.
As it tumbled over once and got up, Hiroki realized it was Kazuo Kiriyama (Male Student No. 6). Ignoring the corpses in the room, he pointed his machine gun to the side of the door which was his blind spot, and immediately began firing away.
After five or six bullets tore through the wall...the gunfire stopped...because he saw no one there.
Now was his chance. Hiroki swung his stick up and leaped onto Kazuo Kiriyama from above. At the last instant he'd decided to climb to the top of the high shelf installed beside the door. He'd decided against using the gun since he wasn't used to it and had tucked it away again. The important thing was to stop the assailant—who turned out to be Kazuo Kiriyama—from shooting anymore.
Kazuo responded by looking up. He lifted the muzzle of his machine gun, but the handle of the broom Hiroki held struck Kazuo's wrist. The Ingram M10 9mm crashed onto the floor, slid, and stopped beyond the table where Satomi Noda was.
Kazuo tried to pull out another gun (it was a large automatic pistol, different from the revolver Toshinori Oda had), but Hiroki, who'd landed and balanced himself, quickly swung the tip of his stick and struck this gun down too.
A rapid assault! I'll strike him down!
The stick came swinging down, but Kazuo quickly bent back and somersaulted backwards. He leaped over Yukie Utsumi's body with the grace of a kung fu master, and after tumbling once he was standing in front of the center table. By the time he was standing he had a revolver in his right hand, the one that belonged to Toshinori Oda.
But even Kazuo couldn't have foreseen Hiroki's agility. He'd immediately moved within eighty centimeters of Kazuo.
"Yahh!" Hiroki swung his stick, striking the gun in Kazuo's hand three times. It flew into the air. Before it landed on the floor, the other end of Hiroki's stick swung at Kazuo's face. There was a table behind Kazuo. He couldn't retreat anymore.
But—the stick stopped several centimeters before hitting Kazuo's face. A third of the stick flew by Kazuo's face. Strangely enough, he only heard it crack later. Kazuo had chopped off the stick with his left hand.
The next moment, Kazuo formed a spear fist with his right hand to strike Hiroki in the face. He was aiming for Hiroki's eyes.
It was a miracle he managed to duck and dodge it. That was how fast Kazuo's fist was.
But Hiroki had managed to dodge it. When he dodged it, he grabbed Kazuo's wrist with his hand that had dropped the stick. The next moment, he twisted his wrist back. Simultaneously, he kneed Kazuo in the stomach with all his might. The absolutely calm Kazuo gasped slightly.
With his left hand restraining Kazuo's arm, Hiroki pulled out his gun and cocked the hammer back. He pressed the gun against Kazuo's stomach and pulled the trigger.
