4. Kurohime’s Preserve

Rin Yuki spoke for the first time on a Thursday morning, three days before the Kasumi Maru was scheduled to sail.

Sato had requested the interview through official channels, filing the paperwork that would place the boy in an interrogation room at nine o'clock. The request was granted, but when Sato arrived, he found Takahashi already there, seated in the corner with his expensive briefcase and his expression of patient condescension. The lawyer had been notified, as was his right, and he had come to ensure that nothing was said that might prejudice his client's interests — by which he meant Kirishima's interests, not the boy's.

"I'll be observing," Takahashi said. "The suspect is a minor, and his psychological state is fragile. I won't allow coercive questioning."

Sato ignored him and sat down across from Rin Yuki. The boy looked worse than he had a week ago. The fluorescent light of the holding cells had bleached his skin to a pale gray, and the shadows beneath his eyes had deepened into bruises. But his posture had changed. The defensive hunch was still there, but beneath it Sato sensed something new — a crack in the fortress, a willingness to let someone see inside.

Sato placed a photograph on the table. It was the booking photo of Emi Tanaka, taken when she had first entered Asahi no Kai at age fifteen. In the image, she was smiling — a cautious, hopeful smile, the smile of a girl who believed she had finally found safe harbor.

"Her name was Emi," Sato said. "She was in your group home. Three months ago, she was transferred to the island. Two weeks ago, her body was pulled from the harbor. She had been shot with an arrow. Her bones show evidence of repeated chases, fractures, restraints. She was sixteen years old."

Rin looked at the photograph. His face, which had been immobile for so long, underwent a series of minute transformations — a tightening around the eyes, a tremor at the corner of his mouth, a swallowing motion that seemed to require enormous effort. When he spoke, his voice was still hoarse, but it was no longer the rusted whisper of their first meeting. It was the voice of someone who had decided, against all his instincts, to trust.

"Her name wasn't Emi," he said. "Not on the island. On the island, we didn't have names. We had numbers. She was Seven. I was Nine."

Takahashi leaned forward in his chair. "I would advise the suspect not to — "

"Shut up," Rin said, without looking at him. The words were quiet but absolute, and Takahashi, after a moment's hesitation, sat back.

Sato leaned forward. "Tell me about the island."

Rin's eyes went somewhere far away. When he began to speak, his voice was flat, reciting facts as though they had happened to someone else.

"The boat leaves at night. They keep you in a holding room at the dock until it's time. The room has no windows. You can hear the water, but you can't see it. When the boat comes, they put a hood over your head and take you on board. The ride takes about an hour. When you arrive, they take the hood off, and you're in a forest. There are lights — small ones, along a path. They walk you to a building. They call it the Lodge."

He paused. His hands, cuffed to the table, had begun to tremble.

"The Lodge has rooms. Each new arrival gets a room. The room has a bed, a toilet, a sink. It looks almost normal. You stay there for a few days. They give you food. They let you rest. They want you to be strong. That's important. The game isn't interesting if the prey is weak."

Sato felt a coldness spread through his chest. "The game."

"They tell you the rules on the third day. A man comes to your room — one of the guards. He explains that you have been selected for a special program. A hunting program. You will be released into the forest on the north side of the island. You will be given a head start. The length of the head start depends on how much the hunters have paid. Sometimes it's ten minutes. Sometimes it's an hour. Then the hunt begins."

"How many hunters?"

"It varies. Sometimes one. Sometimes a group. They're always men. They wear masks — traditional masks, like the ones from the Noh theater. They carry different weapons. Bows. Crossbows. Some use rifles with tranquilizer darts. They prefer to wound first, then close in. It's more satisfying that way." His voice had taken on a clinical detachment that was more disturbing than any emotion could have been. "The forest has traps. Snares. Pits. Some of them were built by the guards. Some of them are natural. The island is rocky, with cliffs on the eastern side. If you're lucky, the terrain kills you before the hunters do."

"How do you know all this?"

"Because I survived. Six hunts. Most don't survive the first one. The ones who do, they get put back in the rotation. The hunters like repeat prey. They say it's more challenging." He looked up at Sato, and his eyes were no longer empty. They were full of a grief so immense it had no language. "I watched them kill Emi. She was in my intake group. We arrived on the same boat. She lasted two hunts. On the third, they put us in the forest together. She was shot in the back while running. I heard her scream. I didn't stop. I kept running. That's how you survive. You don't stop."

The room was silent. Even Takahashi had gone still, his pen frozen above his legal pad.

"How did you escape?" Sato asked.

"The sixth hunt. They put me in the forest with two other prey — a boy named Kenji, who was Twelve, and a girl I didn't know. The hunters that night were a group of four. They were drunk. One of them got separated from the others. He was stalking me through a ravine, and he slipped on the rocks. He fell. His crossbow went off when he hit the ground. The bolt hit him in the leg. I took his weapon. I took his mask."

Rin's voice dropped to a whisper. "I killed him. I didn't mean to. I just wanted him to stop moving. But once I started, I couldn't stop. I kept hitting him until there was nothing left to hit. Then I took his radio and his keys and I ran. I found the dock. There was a boat. I didn't know how to pilot it, but I figured out enough to get it moving. I aimed for the lights on the mainland. I crashed into some rocks near the harbor. I swam the rest of the way."

"And Kirishima?"

"He was at the hotel that night. I didn't know that. I was just trying to find somewhere to hide. I went into the parking garage because it was dark and quiet. He was there. I recognized him. He used to visit the group homes to select the transfers. When he saw me, he smiled. He smiled, and he said my name, and something inside me broke. I remembered everyone he had ever chosen. I remembered Emi. I remembered Kenji. I remembered all of them. And I wanted him to stop smiling."

Takahashi cleared his throat. His face had gone pale. "This is clearly a fabrication. The boy is delusional. I'll be filing a motion to have this testimony excluded — "

"You'll do nothing," Sato said, rising from his chair. He looked at the lawyer with an expression that made Takahashi recoil. "Because if what this boy is saying is true, and I believe it is, then your client is a monster, and every person who has protected him is complicit in mass murder. That includes anyone who tries to bury this testimony. Are you prepared to be named as an accessory, Mr. Takahashi?"

The lawyer said nothing. Sato turned back to Rin.

"I'm going to the island," he said. "Tonight. I need to know everything you can tell me about the layout. The guards. The security. Everything."

Rin nodded, and for the first time since Sato had met him, the boy's expression showed something other than terror or emptiness. It showed hope — a fragile, dangerous hope, the kind that had been crushed out of him a hundred times before, but which had somehow survived.

The boat was a small fishing trawler named the Umineko, and its captain was a man named Higa, a weathered fisherman in his sixties who had once worked under Kenzo Sato's supervision at the eastern harbor. Higa owed the old harbormaster a debt that went back thirty years, to a typhoon season when Kenzo had pulled Higa's son from a capsized vessel. When Sato had explained what he needed, the fisherman had asked no questions. He had simply nodded and said, "Be at the south dock at midnight. We'll sail with the tide."

Sato and Ishigami boarded the Umineko under a moonless sky. Ishigami carried a waterproof bag containing evidence collection kits, a camera, and the tools of his trade — scalpels, swabs, sterile containers. He had also brought a compact pistol, which he handed to Sato with visible reluctance.

"I don't like weapons," Ishigami said. "But we don't know what we'll find out there."

The crossing was rough. Higa navigated without lights, following a route that skirted the main shipping lanes and avoided the harbor patrol's usual sweep. The old fisherman knew the waters around Misono as intimately as a lover's body, and he guided the trawler through channels that did not appear on any official chart.

Two hours into the crossing, the silhouette of Kurohime Island rose against the horizon. It was larger than Sato had expected — a dark mass of volcanic rock and dense forest, crowned by a ridge that ran the length of the island like a spine. There were no lights visible from the sea. The island looked uninhabited, pristine, the kind of place that might be featured in a nature documentary. Only the private dock, visible now as they drew closer, suggested human presence.

Higa cut the engine and let the trawler drift toward a rocky inlet on the island's southern coast. "This is as close as I can get. There's a path up through the rocks. It'll take you into the forest. I'll wait offshore until dawn. If you're not back by then, I'll have to leave."

"We understand," Sato said. He clasped the old man's hand. "Thank you."

Higa's grip was firm. "Your father saved my son. I'm just repaying a debt."

The path through the rocks was treacherous, slick with spray and treacherous underfoot. Sato and Ishigami climbed in silence, their flashlights hooded, their movements careful. By the time they reached the tree line, the trawler had disappeared into the darkness, and they were alone on the island.

The forest was dense, the trees twisted by decades of salt wind. Sato navigated using Rin's instructions — follow the ridge line north, avoid the clearings, watch for tripwires. The ground was uneven, full of exposed roots and hidden hollows. In the darkness, every shadow seemed to move, every sound seemed to signal danger.

After an hour of careful progress, they found the first evidence of what they were looking for.

It was a tree, an old camphor, its trunk scarred with deep gouges. Ishigami ran his gloved fingers over the marks and recognized them immediately. "Arrow impacts. Multiple arrows, over a long period. The tree was used for target practice. Or — " he paused, his face grim, " — or for something worse."

They continued north. The forest opened into a small clearing, and in the center of the clearing stood a structure that Rin had described: a wooden platform, raised off the ground, with a railing around its perimeter. It was a hunting blind, designed to give the occupant a clear view of the surrounding terrain while remaining concealed from below.

Sato climbed onto the platform and found spent shell casings littered across the floor. Tranquilizer darts. Crossbow bolts. A crumpled packet of foreign cigarettes. The blind had been used recently, and often.

Farther north, they found the pit.

It was hidden beneath a lattice of branches and leaves, a trap dug deep into the rocky soil. The bottom was invisible in the darkness, but when Sato shone his flashlight into its depths, he saw something that made his stomach lurch. Bones. Human bones, partially covered by debris, the remains of someone who had fallen into the pit and been left to die.

Ishigami lowered himself into the pit with a rope from his bag. Sato held the light while the pathologist worked, his movements swift and professional despite the horror of the setting. He photographed the remains, collected samples, and documented the position of the body. When he climbed back out, his expression was unreadable.

"Female, probably late teens. The bones show multiple fractures consistent with a fall, but there are also signs of earlier trauma. Arrow wounds. This was a hunting victim, same as Emi Tanaka. She survived the hunt but fell into this trap. The injuries would have been survivable if anyone had come for her. No one did."

They pressed on. The forest grew denser, the undergrowth thicker, until they emerged at the edge of a wide, manicured lawn. In the center of the lawn stood the Lodge.

Rin had described it as a hunting cabin, but the building Sato saw now was more elaborate. It was a two-story structure built in the style of a traditional Japanese inn, with dark wooden beams and a sweeping tiled roof. Light glowed from several windows. Cars were parked in a gravel lot to the side — expensive cars, the kind driven by men who owned shipping companies and served on boards of directors.

Sato and Ishigami approached from the treeline, keeping low. Through a window on the ground floor, Sato could see a lounge area furnished with leather chairs and hunting trophies. But the trophies were not animal heads. They were items of clothing, displayed in glass cases like museum exhibits. A tattered blue uniform jacket. A pair of worn sneakers. A necklace made of cheap plastic beads.

"Souvenirs," Ishigami whispered. "They kept souvenirs."

There was a second building behind the Lodge, a long, low structure that resembled a barracks. Sato guessed it was where the victims were held between hunts. The windows were barred. The door was heavy steel. It looked like a prison, and it was.

They were working their way toward the barracks when a voice cut through the darkness.

"Don't move."

Sato froze. A man had emerged from the trees behind them, a man in dark tactical gear, his face obscured by a balaclava. He held a rifle, and it was pointed directly at Sato's chest.

"I said don't move," the man repeated. "Drop your weapons. Now."

Sato let his pistol fall to the ground. Ishigami set down his bag. The man stepped closer, his rifle steady, and spoke into a radio on his shoulder.

"Perimeter breach. Two intruders. South lawn. Requesting backup."

Within minutes, they were surrounded. Four more men emerged from the darkness, all armed, all masked. One of them stepped forward and pulled the hoods over Sato and Ishigami's heads. The world went black, and Sato felt rough hands binding his wrists behind his back.

They were marched across the lawn and into a building. Sato could tell by the echo of footsteps that they were inside the Lodge. They were pushed into chairs, their hoods removed. They were in a room that looked like an office — wooden desk, leather chair, hunting prints on the walls. The man behind the desk was not wearing a mask.

He was a man in his late fifties, handsome in a weathered way, with silver hair and a face that might have been distinguished if not for the ruin of his right eye. The eye was swollen, the socket surrounded by fresh sutures, the damage so severe that Sato knew immediately what had caused it. A rock. In a parking garage. Wielded by a boy who had watched his friends die.

Katsuhiko Kirishima smiled at them, and the smile was ghastly on his ruined face.

"Detective Sato," he said. "And Dr. Ishigami. I've been expecting you. My lawyer said you were asking inconvenient questions. I had hoped you would see reason. But here you are." He gestured at the room around them. "Welcome to Kurohime."

Sato said nothing. His mind was racing, calculating distances, exits, the positions of the guards. There were no exits he could reach. The guards were too many.

"I must admit," Kirishima continued, "I underestimated you. Most detectives in this city understand how things work. They take their paychecks and they look the other way. But you — you had to be the hero. The crusader. And now you're going to find out what happens to crusaders on this island."

Ishigami spoke for the first time. His voice was calm, almost clinical. "The boy's testimony is on record. The evidence we've collected — the bodies, the logs — they don't disappear just because we're here."

Kirishima laughed. It was a horrible sound, wet and ragged through his damaged face. "Doctor, do you really think this is the first time someone has threatened to expose us? Do you think the city of Misono doesn't know what happens here? The mayor knows. The police chief knows. Half the prefectural assembly knows. They know because they've been here. They've hunted here. This island is the most exclusive club in the country, and its members are very, very powerful."

He leaned forward, his good eye fixed on Sato. "The trial is in two weeks. Your homeless boy will be convicted. He'll be sent to a detention facility, and one day, he'll have an accident. A fall. A fight. Something tragic. And your evidence — the bodies, the logs, all of it — will be lost, or destroyed, or discredited. And the hunting will continue. It will always continue, because the men who come here are the men who run this country. They don't answer to you. They don't answer to anyone."

He sat back and gestured to the guards. "Take them to the holding room. We have a hunt scheduled for tomorrow night. I think our guests have just volunteered to be the prey."
