The sea had retreated too far.
Kamo Itsuki's clone stood atop the building, his gaze fixed on the distant horizon where the water had pulled back, exposing seabed that should never see the light. The air grew heavy, charged with something that made the hairs on his arms stand on end.
"The tide..." His voice was quiet, but Fushiguro Toji heard him clearly.
Toji's eyes narrowed, scanning the sky where clouds gathered with unnatural speed. They churned and boiled, darkening from grey to black, swallowing the sun whole. The wind that followed carried a chill that had nothing to do with temperature.
"Tsunami." Toji's hand tightened on the soul-releasing blade. "A big one."
Below them, Fushiguro Megumi had stopped resting. His Divine Dogs were on their feet, hackles raised, growling at the sea. Other Shikigami materialized around him, drawn by his sudden spike of cursed energy.
He looked up at his father, waiting for instructions.
Toji did not look back. His eyes were fixed on the horizon where a line had appeared—thin at first, barely visible, but growing. Expanding. Rising.
"Get inside the barrier," he said. Not loud. Megumi heard him anyway.
The boy moved, his Shikigami flowing with him, but his gaze lingered on the sea. On the wall of water that was no longer a line but a wave, dark and hungry, climbing toward the sky.
Kamo Itsuki's clone did not move.
He could feel it now—the curse woven into the water, the technique that had pulled the sea back only to hurl it forward. This was no natural disaster. This was a weapon, aimed at the heart of Yokohama, at the barrier that held thousands of unconscious civilians.
"Kenjaku's remnants," he murmured. "Or something older."
"It doesn't matter." Toji's voice was flat. "Can your barrier hold it?"
Kamo's clone did not answer immediately. He was calculating—not the wave's height, not its speed, but the cursed energy coiled within it. Dense. Old. Hungry.
"The barrier can hold." He paused. "The city cannot."
Toji understood. The barrier would protect the unconscious, the civilians, the ones who could not run. But Yokohama itself—the buildings, the streets, the people who had not reached shelter in time—
"The wave is too wide," Kamo continued. "Too fast. Even if I expand the barrier, I cannot cover the entire city before it hits."
Toji looked at the sea, then at the barrier behind them, then at his son, who had reached the edge of the dome and was looking back, waiting for his father to follow.
"Then we don't cover the city." Toji's voice was calm, final. "We break the wave."
Kamo's clone turned to look at him. For a moment, neither spoke.
Then the clone smiled—a thin, sharp expression that did not reach his eyes.
"You're insane."
"Probably." Toji cracked his neck, tested the weight of the soul-releasing blade in his left hand, the spirit-slaying sword in his right. "But I've done crazier things. Remember that fish?"
"That was a curse. A big curse. This is the ocean."
"The ocean's just water." Toji stepped to the edge of the building, looking down at the wave that was now a wall, now a mountain, now a sky. "Water breaks."
He did not wait for an answer. He jumped.
The wind screamed past him as he fell, the city rushing up to meet him, but Toji's eyes never left the wave. It was close now—close enough to see the debris caught in its maw, the buildings already swallowed, the darkness at its heart where the curse coiled.
He hit the ground running.
The street was already flooding, water swirling around his ankles, his knees, his waist. He did not slow. His body, honed by a Heavenly Restriction that had traded cursed energy for impossible strength, carved through the current like a blade.
Behind him, Kamo's clone was already moving. His hands traced runes in the air, expanding the barrier inch by inch, buying seconds that would mean lives.
Toji reached the waterfront as the wave began to curl overhead.
He looked up. The water blotted out the sky. In its depths, something moved—a shape without form, a hunger without end, the curse that had called this wave into being.
Toji smiled.
"Soul-Release Blade."
He swung.
The blade did not cut water. It cut curse. The wave shuddered, its face splitting, its momentum faltering. The thing in its depths screamed—a sound that was not sound, a pain that was not flesh.
Toji did not stop.
He spun, the spirit-slaying sword coming around, its edge gleaming with power that belonged to Kamo Itsuki's genius. The second cut was not aimed at the wave, but at the curse within it, the technique that held it together, the will that drove it forward.
The wave broke.
Water exploded outward, no longer a wall but a storm, a flood, a chaos that could not be controlled. Toji was swept off his feet, dragged under, battered by debris and force that would have killed any ordinary man.
He surfaced, gasping, and saw the wave reforming above him.
'Not enough.'
The curse was healing. The water was gathering. He had bought seconds, minutes, but not enough.
Then the light came.
Behind him, the barrier blazed—not the soft, steady glow of protection, but something sharper, brighter, focused. Kamo Itsuki's clone stood at its center, his hands raised, his eyes blazing, his body already beginning to dissolve.
'He's not expanding the barrier,' Toji realized. 'He's redirecting it.'
The light struck the wave. Not to hold it back—to cut it. To split it, to scatter it, to turn one killing blow into a thousand harmless ones.
The water parted. The curse screamed again, but this time there was no power behind it, no will to resist. It dissolved into the scattered foam, into the rain that now fell gentle over the broken city.
Toji stood in the shallows, chest heaving, watching the water recede. Behind him, the barrier pulsed once, twice, then steadied.
He looked up at the building where he had stood moments ago. Kamo's clone was gone—dissolved, expended, used up in that final act of defiance.
But the barrier held. The people inside were safe. The city was broken, but not lost.
Toji turned and began to wade back toward the shore, toward his son, toward the work that remained. Behind him, the sea returned to its bounds, sullen and quiet, its stolen power spent.
For now.
The water did not recede.
It settled, sullen and vast, swallowing Yokohama whole. Buildings that had stood for decades became islands—jagged silhouettes against a grey sky, their lower floors drowned, their windows shattered, their signs hanging at desperate angles. Cars floated like forgotten toys, bumping against lampposts and storefronts with dull, rhythmic thuds. Photographs drifted past—faces of strangers, moments of joy, now sodden and lost.
Above it all, the guardian barrier held.
It was a bubble of light in a world turned dark, a dome of safety that the flood could not breach. Inside, thousands slept, unaware of the sea that had risen to swallow their city.
On its peak, three figures stood.
Kamo Itsuki's clone was fading—not gone, not yet, but thinner than before. The effort of redirecting the barrier had cost him, and he could feel the edges of his existence beginning to fray.
Beside him, Fushiguro Toji was coiling the Chain of a Thousand Miles around his weapons, connecting soul-releasing blade to spirit-slaying sword, preparing for something that would require both. His expression was calm, but there was a tension in his shoulders that hadn't been there before.
Fushiguro Megumi stood a step behind them, his Divine Dogs at his feet, his other Shikigami circling above. His face was pale, but his voice was steady.
"This tsunami... it wasn't natural, was it?"
Kamo shook his head. "If it were, we'd have had warning. Evacuations. Time." He looked out at the flooded city, at the wreckage of Yokohama. "This was deliberate. And whatever caused it—"
"Is still here." Toji finished the thought. He had attached the last link, tested the weight, found it good. "And it's strong. Strong enough to do this, strong enough to hide until now."
He looked at his son. "Megumi. You know what to do if things go wrong?"
Megumi's jaw tightened. "Get inside the barrier. Don't be a hero."
"Good." Toji's lips twitched into something that might have been a smile. "Your mother taught you that."
"I learned it from watching you nearly die."
"That's called 'leading by example.'"
Kamo's clone made a sound that might have been a laugh. "You two can bond later. We have company."
The water stirred.
It began as a ripple, then a current, then a churning that pulled debris into its center, spinning it faster and faster until the whirlpool was wide enough to swallow a city block. The air grew thick with cursed energy—dense, ancient, hungry.
And from the depths, something rose.
It emerged slowly, deliberately, as if savoring the moment. Its body was the color of blood, its limbs thick and powerful, its face a tangle of tentacles striped in black. Wings spread from its hips, leathery and vast, dripping seawater that turned to steam as it touched the air.
Dagon. Special Grade Cursed Spirit. Lord of the Depths.
It stood on the water as if on solid ground, its many eyes fixed on the barrier, on the figures atop it, on the father and son who dared to stand against the sea.
"Fushiguro Toji." Its voice was the crash of waves, the groan of drowning cities. "I had heard you were dead."
Toji's smile was thin and sharp. "Rumors of my death were greatly exaggerated. Usually by people who are now dead themselves."
"Your son, then." Dagon's eyes slid to Megumi, and something in its gaze sharpened. "The Ten Shadows. How fitting. I wondered if the bloodline would survive."
"It did." Toji stepped forward, one blade in each hand, the chain between them singing softly. "And I'm not dying today. Not to you. Not to anyone."
Dagon's tentacles spread wide, blocking out the sky. "You think you can stop me? I am the sea. I am the storm. I am the depths that swallow all light. You are just a man."
Toji began to walk toward the edge of the barrier, toward the water, toward the thing that had drowned his city.
"I'm not just a man."
He stepped off the barrier and into the air, and for a moment, he hung there, suspended between sky and sea, between what he was and what he had chosen to become.
Then he fell—not down, but forward, toward Dagon, toward the heart of the storm, toward the battle that would decide if Yokohama lived or died.
Behind him, Kamo's clone raised his hands, preparing to support where he could.
Behind him, Megumi watched his father fly toward a god of the deep with nothing but two swords and a chain, and wondered if courage was something you learned or something you were born with.
The water rose to meet them both.
