4. Immediate Appeal

The excavation crew arrived at midnight, four men in a windowless van that smelled of diesel and brine. Jun had found them through a contact in the southern islands, a chain of introductions that began with a former salvage diver and ended with a man who called himself only "Captain." The Captain was fiftyish, sun-leathered, with the powerful shoulders of someone who had spent decades wrestling with the sea. His three companions were younger, silent, their faces obscured by the shadows of baseball caps pulled low. They spoke a dialect of the southern archipelago that Kaito could barely follow, a rapid-fire patois that seemed designed to exclude outsiders.

Kaito met them at the southern service road, a gravel track that branched off the main airport access route and wound through a copse of stunted pines before terminating at a drainage culvert. It was the least visible approach to the garrison site, shielded from the airport's security cameras by the bulk of a disused cargo warehouse. He had scouted the location himself three nights earlier, walking the perimeter alone while the airport's runway lights pulsed in the darkness like a line of grounded stars.

The Captain surveyed the site with the practiced eye of a man who had dug up things better left buried. He carried no flashlight, relying instead on the ambient glow of the distant city reflected off the low cloud cover. His boots crunched softly on the gravel as he walked to the edge of the survey markers.

"You want us to dig here," the Captain said. It was not a question.

"Grid coordinates 34-17," Kaito confirmed. "Approximately eight meters down. There is a void, likely concrete. I need to know what is inside it."

The Captain turned to face him, his expression unreadable in the darkness. "Eight meters is not a shallow grave, Yashiro-san. Whoever put something down there did not intend for it to be found. What exactly are we looking for?"

Kaito hesitated. The truth was dangerous, but a lie would be worse. These men were professionals, and professionals despised being deceived about the risks they were taking. "I believe there are human remains," he said quietly. "A man who disappeared in 1978. My father's generation buried him in the fill material when the land was reclaimed."

The Captain absorbed this information without any visible reaction. He pulled a cigarette from his jacket pocket and lit it, the match flaring briefly in the darkness. "The ground here is saturated. The water table is high this close to the bay. If there are remains, they will be in poor condition after forty-seven years in wet concrete. The forensic value will be degraded, but not destroyed. DNA can survive surprising conditions."

"You have experience with this kind of recovery?"

"I have experience with many things," the Captain said, exhaling smoke. "My price has just doubled. Hazard pay."

Kaito nodded. The money was irrelevant. What mattered was speed and silence.

The crew unpacked their equipment with efficient precision. It was not the heavy machinery of a legitimate excavation but a collection of portable, specialized tools: a ground-penetrating radar unit that folded into a backpack, an auger drill with diamond-tipped bits that could core through reinforced concrete, and a compact water pump with a sound-dampened motor. They worked without speaking, each man knowing his role.

While two of the crew members calibrated the radar unit, the Captain unrolled a laminated map of the original reclamation grid. It was the same chart that Endo the surveyor had shown Kaito, but this version was annotated with additional markings in a spidery hand. The Captain traced the grid lines with a calloused finger.

"Pier seven, section eight," he murmured. "That was the old notation system from the 1990s reclamation. The piers were the reference markers, concrete pillars driven into the seabed before the fill was added. Section eight was the easternmost quadrant. Your father's coordinates are precise, but the reclamation was not a precise operation. The fill was dumped in layers, compacted by bulldozers, and paved over. The void may have shifted as the ground settled."

"Can you locate it?"

"We will try."

The radar operator called out a reading. The void was faint but detectable, a ghostly outline on the screen that suggested a hollow space approximately two meters in diameter. It was not directly beneath the coordinates Kaito had specified but shifted slightly to the north, perhaps a meter and a half off-center. The Captain nodded, adjusted the drill position, and gave the signal to begin.

The auger bit into the earth with a low whine, its diamond teeth chewing through the packed fill material. Soil samples came up in the coring tube: first the asphalt of the original service road that had been buried during the reclamation, then a layer of compacted gravel, then a dark, wet loam that smelled of salt and decay. The drill descended in measured increments, each meter marked by the addition of a new extension rod.

Kaito watched from the edge of the work zone, his heart pounding. The night was unnaturally quiet, the silence broken only by the hum of the drill and the distant crash of waves against the seawall. In the darkness, he could almost hear his father's voice, that low rumble that had once seemed so authoritative, now echoing with a menace he had never recognized in life. The land remembers what we bury in it.

At 4.7 meters, the drill hit something solid. The Captain raised a hand, and the motor stopped. The crew gathered around the borehole, their flashlights trained on the opening.

"Concrete," the Captain said, inspecting the drill bit. "Reinforced with rebar. This is structural-grade material, not fill. It was placed here deliberately."

"Can you break through it?"

The Captain nodded slowly. "We can, but it will take time. The rebar will slow us down. And we need to be careful. If this is a burial vault, breaking through too aggressively could damage what is inside."

He replaced the auger bit with a smaller, diamond-coated coring tool designed for precision work. The drill resumed its work, slower now, the sound higher-pitched and more insistent. Kaito paced the edge of the work zone, his eyes scanning the darkness for any sign of patrols or security cameras. The airport's perimeter fence was two hundred meters away, its chain links topped with razor wire. Beyond it, the runway lights blinked in their steady, automated rhythm. The world was asleep, but Kaito felt as though he were standing on the edge of a precipice, the ground crumbling beneath his feet.

At 5.9 meters, the drill broke through. The Captain withdrew the coring tool and shone a flashlight into the borehole. For a long moment, he was silent, his face illuminated from below by the reflected light.

"There is a cavity," he said. "Several feet deep. I can see the walls—smooth concrete, like the inside of a pillar. And at the bottom..." He paused, adjusting the flashlight. "There is something there. Fabric, perhaps. And bone."

The word hung in the air like a curse. Kaito felt his legs weaken. He had known what they would find, had known it since the moment he opened the box his father had left behind. But knowledge was not preparation. The reality of the discovery struck him with a force that was almost physical, a nausea that rose in his throat and threatened to overwhelm him.

"We need to remove it," he said, his voice hoarse. "Tonight. Before anyone else finds it."

The Captain looked at him with an expression that was not quite pity and not quite contempt. "Yashiro-san, I am sorry, but that is not possible. The remains are encased in concrete. To extract them without heavy machinery would take days, and it would destroy whatever forensic evidence remains. The best we can do is seal the borehole and hope the site is not excavated further."

Seal the borehole. Leave the body in place. Hope that the judge did not order a full excavation. It was a gamble with impossible odds, and Kaito knew it.

Before he could respond, a light flickered at the edge of his vision. A vehicle was approaching along the service road, its headlights dimmed but unmistakable. Kaito's blood ran cold. The crew froze, their hands still on the equipment.

"Police?" the Captain asked, his voice calm but edged with tension.

Kaito squinted into the darkness. The vehicle was a sedan, not a patrol car, and it was moving with the slow, deliberate pace of someone who knew the terrain. As it drew closer, he recognized the silhouette of the driver.

It was Jun.

Jun parked the car fifty meters away and walked toward them, his footsteps crunching on the gravel. His face was pale, and he was holding his phone in one hand, the screen still glowing with an open message.

"Aniki," he said, his voice low but urgent. "We have a problem."

"What kind of problem?"

"The High Court ruling. It was released an hour ago. The judge has issued an order for a supplemental environmental survey of the garrison site, including a full geological investigation of the anomalous void. The survey is to begin in three days."

Kaito stared at him, the words slowly resolving into meaning. The judge had done exactly what he had feared. The curiosity that had been piqued during the hearing had transformed into a formal order. The court was going to excavate the site, and when they did, they would find everything.

"Three days," Kaito repeated numbly. "That is not enough time."

"There is more," Jun said. He held up his phone, the screen displaying a news article. "The Aozora Peace Alliance has filed a second petition, this one with the High Court directly. They are appealing the dismissal of the initial injunction. The appeal will be heard next week. Emi Harada is holding a press conference tomorrow morning to announce a new campaign to halt the construction permanently."

The walls were closing in. The legal process, which Kaito had once believed would be his shield against the clan's violent past, was now the mechanism that would expose it. The judge's survey order, the protesters' appeal, the body entombed in concrete beneath the site—all of it was converging on a single point of catastrophic revelation.

"Seal the borehole," Kaito ordered the Captain. "Do it now. Make it look like nothing was here."

The crew scrambled to comply, reversing the drill and extracting the extension rods, filling the hole with a quick-setting slurry that would disguise the intrusion from a casual inspection. But Kaito knew it was a temporary measure at best. A full geological survey would detect the disturbance, and a forensic excavation would find the body regardless of how well the borehole was concealed.

As the crew packed their equipment and prepared to depart, the Captain pulled Kaito aside. "I have been doing this work for twenty years," he said quietly. "I have recovered bodies from the ocean floor, from collapsed mines, from mass graves left by wars that the world has forgotten. In all that time, I have learned one thing: the dead do not rest until they are ready. And this one, whoever he is, is almost ready to rise."

The van disappeared into the night, its taillights vanishing around a bend in the service road. Kaito stood alone in the darkness, the weight of his inheritance pressing down on him like the concrete that entombed Shinichi Hara. The journalist had waited forty-seven years. Three more days would make no difference.

But for Kaito Yashiro, those three days would determine whether he would follow his father into the darkness or find some other path, some narrow passage between the law and the underworld that would allow him to survive what was coming.

He climbed into Jun's sedan, and they drove back to the city in silence. The first light of dawn was breaking over the bay, painting the water in shades of rose and gold. It was beautiful, Kaito thought, in the way that endings are sometimes beautiful. A moment of grace before the reckoning.

In the Higurashi-no-mori shrine, Tetsuzan Kawada received a phone call. The voice on the other end was one of the crew members from the southern islands, a man who had been paid to dig and also paid to report.

"They found it," the voice said. "The son knows everything."

Kawada closed his eyes and let out a long breath. The game had changed. Kaito was no longer a misguided idealist; he was an active threat. And threats, in the world of the Yashiro-kai, were dealt with decisively.

"Prepare the council," Kawada said. "We will meet tomorrow. It is time to discuss the succession."
