The impact didn't just hit Akira. It crushed through him, a physical manifestation of the ocean's absolute weight. The force drove his body backward across the ancient stone path, his boots carving deep, jagged fractures into the barnacle-encrusted surface before he finally skidded to a halt. The walls of suspended water around him trembled violently, massive ripples forming as if the Atlantic itself were convulsing in reaction to the clash.
For a brief, ringing moment, there was only the sound of rushing blood in his ears. Then Akira exhaled, a sharp, white mist escaping his lips. It wasn't a breath of pain, but of cold realization.
"…That wasn't cursed energy," he said quietly, his voice layered with the resonant hum of the Abyss.
The entity standing before him lowered its arm with a deliberate, agonizing slowness. Its form, which had been a flickering ghost only moments before, was beginning to stabilize. It was adapting to his presence, pulling matter from the surrounding silt and salt to give itself a more permanent, lethal definition.
"…Of course it isn't," the Abyss King murmured from the depths of the Library. "This place, these guards... they predate your modern understanding of power. You are fighting the physics of a lost world, Akira."
Akira straightened his back, the black silk of his uniform torn and damp. The pressure here was fundamentally different from the urban tension of Tokyo. Every movement felt heavier, slower—not because of the physical density of the water, but because of a conceptual drag. His authority, his Sovereign's Command, wasn't flowing with its usual fluid arrogance. It was being resisted. It was being tested by an older law.
The entity stepped forward, the ancient stone groaning under its weight. "…You carry the Crown," it said, the voice vibrating through Akira's skull. "Then prove you are not the same mistake we sealed beneath the waves ten thousand years ago."
Akira's eyes narrowed, the gold and violet swirling into a storm of defiance. "I don't prove anything to shadows," he replied, his voice hardening. The ground beneath his feet cracked as he exerted his will. "I decide what remains and what is erased."
The entity moved again, faster than the eye could track through the distorted light of the trench. This time, Akira was ready. He raised his hand, the violet-gold sigil flaring with desperate intensity.
"Stop."
Nothing happened. For the first time since the warehouse in Morocco, his command failed. The word hung uselessly in the air, swallowed by the salt and the silence. The entity's strike landed—a direct, crushing hit to his side that launched him off the stone path and headlong into the suspended wall of water.
The moment his body touched the liquid barrier, the ocean swallowed him.
Darkness. Cold. A pressure that felt like the world was trying to turn his bones into dust. Akira's eyes snapped open underwater, but this wasn't the fluid, yielding water of a swimming pool. It didn't flow; it held. It was a prison made of pure, concentrated weight. His body didn't sink; it stayed suspended, locked in place like an insect trapped in amber.
"…So this is the trial," he thought, his mental voice echoing strangely through the dark.
Above him, the stone path remained an island of stability in the void. The entity stood at the edge, a silent sentinel watching his struggle. Waiting to see if the new Sovereign would drown in the legacy of the old one.
"…You command matter, Akira," the King said slowly, his voice a tether to reality. "Steel. Structure. Form. You have ruled the things that men have built."
Akira clenched his hand, his fingers clawing at the unyielding water. The Red Tower shard in his palm flickered weakly, its crimson light struggling against the gloom.
"…But here, matter is not yours to command," the King continued. "This water is the memory of the world's first grief. It does not obey the laws of the surface."
The water tightened around him, rejecting his presence, pushing into his lungs without him even taking a breath. Akira's heart rate slowed. His frantic movements ceased. He stopped fighting the pressure and, for the first time, he listened to it.
"…You're not just pressure," Akira whispered internally. The water around him trembled at the vibration of his thought. "…You're a system. A cycle of weight and time."
Above, the entity's head tilted. It saw the change in the boy's aura.
Akira raised his hand with agonizing slowness, no longer forcing his will upon the ocean. Instead, he reached out to the resonance of the city below, to the salt in his own blood that called out to the salt in the sea.
"…Protect me."
For a heartbeat, there was nothing but the crushing dark. Then, the water shifted. It didn't explode or surge in a violent current; it aligned. The lethal pressure around his body redistributed, forming a dense, rotating layer of current that orbited him like a moon. It wasn't resistance; it was cooperation.
Akira moved. He stepped forward inside the ocean itself, the water parting around him like a living shield, bowing to the authority of one who had learned to listen.
"…Good," the King said, a note of dark amusement in his tone. "You're finally learning that a Sovereign doesn't just dictate; he harmonizes."
Akira looked up at the path above. Then, he pushed. "Rise."
The ocean obeyed. A massive column of water erupted upward, a geyser of pure authority that carried him back onto the stone path in a violent surge. Akira landed in a crouch, calm and stable. Water circled his right arm now, compressed into a flowing, blade-like current that hummed with the power of the depths.
"I don't need to control every drop," he said, standing tall as the General watched him. "I just need the sea to accept that I belong here."
The General was silent for a long moment. Then, its form solidified further, ancient and corroded armor forming across its chest, marked with the same blues and golds that lit the city. "…Then you may pass the first threshold, Usurper. I was a General of the King you carry in your soul."
Akira didn't react outwardly, but inside the Library, the Abyss King smiled.
"…And I was left here," the General continued, his voice a low funeral dirge, "to ensure the Crown never returns to the sun. Because we remember what happened the last time the sky saw that light."
The ocean trembled again, but this time it wasn't from tension. It was an awakening. Far below the ruined city, something massive shifted in the silt—a colossal movement that sent tremors up the stone path. Akira's gaze moved past the General, toward the heart of the sunken ruins.
And then, he saw it. A faint, pulsing crimson light, deeper and more ancient than the shard from the Red Tower.
"…There," Akira said, his own shard vibrating in a frantic, hungry symphony.
The General stepped aside, not blocking him, but not granting him safety either. "…The throne awaits. But the throne is not empty."
The ground ahead collapsed inward, forming a descending gate that led into the bowels of the city. Beyond it lay a darkness that felt alive, breathing with a rhythmic, heavy heat.
"…One final guard," the General said quietly. "The one who took my place when the lights went out."
Akira stepped forward without a hint of hesitation, the water blades around his arm sharpening into crystalline edges. "I didn't come across the world to turn back at the door."
The gate opened fully. From the blackness emerged a beast that defied the logic of the natural world. It was a mass of coral, fossilized bone, and something that still moved and bled inside the stone. Its eyes opened slowly—huge, abyssal orbs of deep red that matched the glow of the shard.
The entire sunken city screamed as the beast moved, its bulk displacing the gravity of the trench. Akira felt the weight again, but it wasn't the ocean this time. It was the presence of a relic of a war that had never truly ended.
"…That's not a guardian," Akira said, his hand tightening.
The King's voice dropped to a whisper, cold and certain. "No… that's what happens when a weapon is left to rot in the dark for ten millennia. It becomes the hunger itself."
The beast lunged, and the throne behind it burned with the light of a dying star.
