The Monument of Salt and Silence

The sky was bright and clear, a mocking contrast to the black sea below. The sea didn’t shimmer or reflect the sun. It was a thick, oily black that seemed to swallow the light before it could hit the surface. 

The only noise was the rhythmic, industrial thrum of the ship's engine. There was no cawing noise of seagulls begging for scraps or the splashing sound of dolphins breaking the surface. Just a heavy, dead silence. Kousuke stood at the railing, the "black abyss" staring back into his soul until his eyes ached.

He watched Yuuto through the corner of his eyes. The boy was small, his hands gripping the cold metal railing. Kousuke reached into his pocket and pulled out a crumpled pack of cigarettes, lighting one with a hand that shook only slightly. He’d packed enough for six months, but watching the way the kid leaned toward the water, he already felt the nicotine craving spiking.

They looked like a father and son on a cruise trip, if not for the team of men in yellow hazard suits watching them from the observation deck—like plastic toys against the gray ship. Or undertakers bringing the exiles to the graveyard.

The incident a few days ago had been red—a blinding, searing heat that turned the sky to fire. But the aftermath was black. The sea was now the soup of the nuclear waste and the thousands of lives it claimed. It was hell on earth and made him wonder why he was still here. Maybe to watch over the man-made purgatory underneath?

He should have died in the blast. The fact that he didn't mean he owed something—to the dead, to the universe, to his own gnawing guilt. Six months in a lighthouse over a mass grave? That felt about right.

Before he knew it, the ship had already arrived at the lighthouse. One that had stood still since the First World War and survived the blast. A monument for this giant sea grave.

The men in hazard suits worked in eerie silence, sliding supply crates down the connected pipe without setting foot on the island's rocky shore. They moved with the efficiency of people performing a burial—quick, clinical, no eye contact.

Kousuke wanted to ask when the next supply drop would be. When the pickup was scheduled. But the way they turned away the moment the last crate hit the ground told him everything he needed to know.

The boat's engine roared to life before he could form the question.

Kousuke's mission was simple: maintain the light, report weekly on “abnormal phenomena”, and survive the 6-month quarantine. If he did, the mainland promised him a life.

He didn't expect the variable that was Yuuto, another survivor who was now adjusting his dinosaur backpack. The kid had no family left, and he didn't want to be in the research quarantine facility.

“Can I go with you?” Yuuto had asked back at the facility, his small hand tugging on Kousuke’s sleeves, his eyes big and begging. 

“Sure, why not?” Kousuke answered, too quickly, too easily. A reflex born of his own terror of being alone with the silence. 

It was their first meeting, and now Kousuke was technically Yuuto's unofficial guardian. Taking care of a kid in an isolated place was like adding an extra burden on the already difficult task. But he knew he would go insane if staying alone for that long.

He helped Yuuto set their stuff in the rooms. Yuuto took the small room with the round porthole window. Kousuke took the room near the observation deck, where the radio sat like a silent, judgmental beast.

He set up his study table, neatly arranged with Manila folders and a thick leather-bound journal, and a pen. It was a performance of normalcy.

Day 1:

Thorough check of the structure. Needs minor maintenance, but overall held together well.

Tomorrow I will clean the engine and generator, and check the basement seawater level.

Indoor humidity is low—good for preventing mold.

Air quality is poor, as expected. Medium radiation levels detected.

The underground water well remains intact, unaffected by contamination. Still need to test the filter system.

Yuuto asked if the sea is always this quiet. I didn't know how to answer him.

…

Kousuke closed the journal. The ink felt too black, matching the water outside. He went to check on Yuuto. 

The boy pressed his face to the round window, his breath mingling with the glass. 

“Liking the view here, buddy?” Kousuke asked, leaning against the doorframe. He went to light another cigarette but stopped, remembering the rations.

“I rarely saw the sea before.” Yuuto hopped down and faced Kousuke. His face was bright and tingling with excitement that was out of place for this dead place. 

“You can go down and play in the sand, you know,” Kousuke said, forcing a smile, “Just stay away from the water. It’s... not for swimming.”

***

Kousuke watched Yuuto making a sandcastle and drawing on the sand with a random piece of driftwood. The boy seemed to be very focused on the task. It was a collection of strange, swirling patterns, or maybe just Yuuto’s way of drawing fish. If not for the looming presence of the black sea ahead, it could just be a gentle getaway for two of them. 

There were times when Yuuto would stop playing and standing up, perfectly still, head tilted as if sensing something in the waves. But those didn't last long; a few seconds later, the boy went back to his castle.

Kousuke couldn't sleep at night. The silence was too much for him. He was used to the city noise, the roaring of car engines. Here, the silence felt like it was pressing against his eardrums, trying to get inside. His best bet was to pretend the sea had a heartbeat and its rhythm was his lullaby. 

A soft knock came at his door. Yuuto stood there, wrapped in a blanket.

“Do you hear it too?” Yuuto asked.

“Hear what?” Kousuke asked, curious.

“The voices in the ocean,” Yuuto answered, his voice uncertain, like he was trying to translate a language he didn't quite understand.

“I don't hear them,” Kousuke said, his heart giving a strange, uncomfortable thud. “But I wish I could. Maybe they’re more interesting than the silence.”

“Wanna sit by the beach now? Maybe we can see the moon and the star from there,” Yuuto tilted his head.

They climbed down the spiral stairs, their shadows dancing wildly against the stone. They spread a blanket on the cold sand, far enough from the lapping black tongue of the tide. There was no moon, but the stars were terrifyingly bright, reflected in the oily water like sunken diamonds.

The light shone through the ocean, like the lantern that guided the lost ship. But in this case, there was nothing to guide except the dead. 

The breeze carried the scent of salt and rot—the smell of things that had been underwater for too long.

And then, Kousuke froze.

It was faint. A melody, drifting up from the black depths. It wasn't quite singing, and it wasn't quite the wind. It was a low, vibrating lilt, like a mother humming to a child through a thick wall. It was patient. It was ancient.

"Do you hear that?" Kousuke whispered, his skin crawling.

Yuuto nodded, pulling his blanket tighter. He didn't look scared. He looked... recognized. His eyes were fixed on the water, unblinking, watching for a shape that wasn't there yet.

The lullaby continued, rising and falling with the black tide. It sounded like it had all the time in the world. 

As if it knew they weren't going anywhere.
