The training grounds of the Void Academy were no longer a place of silence. They were a place of Resonance.
Under the grey, bruised sky of the grounded Capital, fifteen thousand students sat in perfect, geometric rows. In the center of the courtyard, Kaito stood atop a raised obsidian dais. He wasn't wearing his Royal Gladiator silks; he was back in the simple black linen of a laborer, his moon-white hair tied back with a scrap of his iconic crimson scarf.
"Fear is a vibration," Kaito's voice rang out, clear and cold. "When you are afraid, your atoms shake. You leak heat. You leak kinetic potential. To the Star-Eaters, you are a beacon of wasted energy. To master the Void, you must first master the stillness of your own soul."
The First Ascension: The Trial of the Still Heart
Kaito raised his hand. [Technique: Zero-Field Expansion].
A ripple of silver light expanded from his feet, covering the entire courtyard. Instantly, the ambient temperature plummeted. The moisture in the air crystallized into a fine, sparkling dust. For the students, it felt as if their very blood was turning into slush.
"Stop the shivering," Kaito commanded. "Don't fight the cold with heat. Harmonize with it. Lower your own internal frequency until the cold has nothing to bite."
In the third row, a young girl named Mina—the first student Kaito had pulled from the pods—was trembling violently. Her "Zero-Soul" was erratic, sparking with a faint, uncontrolled purple light. She was fighting the cold, her body trying to generate heat through sheer panic.
Rin walked over to her, placing a gentle hand on Mina's shoulder.
"Mina, listen to my heartbeat," Rin whispered. [Technique: Echo-Sync].
Rin projected a steady, slow rhythm. Mina gasped, her sightless eyes widening as she felt Rin's pulse. Slowly, the girl's breathing deepened. Her shivering slowed. She stopped fighting the cold and began to "sink" into it.
Suddenly, the purple sparks around Mina vanished. They were replaced by a soft, silver hum.
[Achievement: First Student Awakening – Void-Pulse Unlocked]
Mina opened her eyes. She wasn't cold anymore. She was Still.
The Science of the Void-Pulse
"Look," Kaito said, pointing to Mina.
The air around the young girl was distorting. She wasn't just sitting there; she was accidentally creating a Kinetic Sink. The falling snow avoided her, curving around her body as if repelled by an invisible wall.
"She has found her Zero-Point," Kaito explained to the class. "She isn't using power to push the world away. she is removing herself from the world's equation. This is the Void-Pulse. It is the first step toward the Absolute Zero."
The Hidden Frequency
While the students practiced, Rin pulled Kaito aside to the edge of the courtyard. She looked exhausted, her Echo-sense strained.
"Kaito, I found something during the sync with Mina. When she reached her Zero-Point, I heard a 'hiss' coming from the rift in the sky."
Kaito sharpened his Void-Sight, looking up at the mercury-needle ships hovering in the stratosphere. "A hiss? Like a leak?"
"No," Rin said, her face grim. "Like a broadcast. The Star-Eaters' ships aren't just hovering. They're singing. It's a sub-atomic frequency that keeps their 'Living Singularity' suits stable. If we can find a way to interrupt that song..."
"We can dissolve them before they even land," Kaito finished.
He looked at the fifteen thousand students, now all struggling to reach the same stillness as Mina.
"We don't just need warriors, Rin. We need an Orchestra. If I can teach them to pulse in unison, we can create a planetary interference field."
The Darkening Sky
The lesson was interrupted by a thunderous crack from above. The rift in the sky widened, and three more needle-ships descended, much larger than the scout Kaito had destroyed. They didn't land; they began to circle the Capital, dropping Gravity Anchors that glowed with an ominous, sickly violet light.
"They're not waiting for us to finish training," Kaito muttered, the Null-Edge appearing in his hand.
He looked at Mina and the other students. They were still far from ready. Most could barely hold the pulse for ten seconds.
"Rin, take the lead students to the Spire's roof. Use the clockwork gears as amplifiers for your Echo-sense. I'll buy you time."
"Kaito, you can't face three of them alone! Your marrow hasn't recovered from the last fight!
Kaito adjusted his scarf, his eyes turning into endless, violet pits.
"I'm not going to face them," Kaito said, his voice dropping to a frequency that made the ground groan. "I'm going to ground them."
[Absolute Zero: Gravitational Collapse]
Kaito didn't jump. He simply stepped off the dais and into the air, folding the space beneath his feet.
The Academy watched as their master ascended into the bruised sky—a single, silver-white spark flying toward a fleet of cosmic predators. The first war of the Singularity Era had truly begun.
