The atmosphere in the throne room of the Black Coral Temple had shifted from a battle to a massacre. General Vane, usually so composed and arrogant, was now stumbling backward, his polished boots slipping on the blood of his fallen guards. The air, or rather the water, felt heavy—so heavy that the imperial soldiers still on the ships above could feel the vibration in their sonar. It was a pressure that didn't come from the depths, but from the boy standing in the center of the room.
Kaito stood in the center of the chamber, his feet barely touching the white sand. He wasn't just breathing; he was flowing with the currents. The white light in his eyes wasn't just magic—it was the soul of the ocean itself, awakened by his desperation and his bloodline. This was the "Abyssal Core," a legendary power that the Iron-Empire had spent centuries trying to replicate with their cold, mechanical steam-engines. But some things cannot be manufactured; they can only be inherited through blood and sacrifice.
"I told you, Vane," Kaito's voice echoed, sounding like the roar of a distant tidal wave hitting a jagged cliff. "The sea doesn't belong to the Empire. It doesn't belong to your steam, your steel, or your greed. It belongs to those who protect it."
Vane gritted his teeth, his hand trembling as he reached for a backup device on his belt. His face was pale, the shadow of the temple's obsidian pillars making him look like a ghost of the man who had entered. "You're just a mutation, boy! A freak of nature! The Iron-Empire has tamed storms, and we have conquered the surface. We will tame you, even if we have to burn the very ocean to do it!"
He threw a handful of Magnetic Disks toward Kaito. In mid-air, the disks expanded, clicking into place to create a high-voltage electrical net designed to paralyze even a Great Kraken. The blue sparks hissed in the water, turning it into a deadly trap. But Kaito didn't move. He didn't even blink. He simply raised a single hand, palm facing forward, and the water pressure around the disks increased so rapidly that they were crushed into tiny, useless metal cubes before they could even release their first spark.
"My turn," Kaito whispered, a cold chill running through the room.
With a speed that the human eye couldn't track, Kaito disappeared. He didn't swim; he became the current. He reappeared directly in front of Vane, his father's dagger pulsing with a white-hot intensity that illuminated the General's terrified face. Kaito didn't stab him; instead, he tapped the flat of the blade against Vane's reinforced brass chest-plate.
"Abyssal Art: Internal Implosion!"
The impact wasn't loud, but the result was devastating. The high-pressure steam-engine attached to Vane's suit, designed to withstand the crushing depths, suddenly had its flow reversed. The pipes hissed and groaned, the metal screaming under the sudden change in physics, before exploding outward in a cloud of superheated bubbles. The force sent the General flying across the room, crashing into the base of the pearl throne. He slumped there, his golden uniform charred and tattered, his breathing coming in ragged, wet gasps.
Outside the temple, the imperial destroyers were in absolute chaos. Their sonar screens were white with interference. The Azure Ghost, still docked in the shadows of the temple walls, began to hum in sync with Kaito's heartbeat. Its engine, the Heart of the Iron-Whale, was drawing power directly from the temple's ancient core, its bioluminescent lights turning from a calm blue to a fierce, regal white.
Kaito turned his attention away from the defeated General and toward the Eternal Frost, the block of magical ice holding his father. He knew that the fight with Vane was just a distraction—a preamble to the real challenge. Breaking a seal that had lasted for a decade was not about strength; it was about resonance. But with the Abyssal Core awakened within him, the ice no longer looked like an unbreakable wall—it looked like a frozen river waiting for the sun to rise.
"Hang on, Father," Kaito murmured, his hands glowing as he touched the surface of the ice. The coldness didn't bite him; it welcomed him. "I'm bringing you home. I'm finishing what you started."
But just as the first thin crack appeared in the center of the ice block, a massive, soul-shaking alarm sounded from the seabed. It was a sound Kaito recognized from the naval academies—the Depth-Buster. The Empire's ultimate fail-safe. It was a massive cylinder filled with concentrated heat-magic and unstable crystals, designed to evaporate entire miles of ocean floor to "sanitize" a battlefield. And it was heading straight for the temple's coordinates.
Kaito looked at the depth gauge on his wrist. The projectile would hit in exactly three minutes. Three minutes to break the ice, get his unconscious father into the Azure Ghost, and outrun a blast that would level the entire Silent Abyss.
"Three minutes," Kaito gritted his teeth, his eyes flaring with renewed power. "That's more than enough."
